== I want to be one of your Google Summer of Code students, what should I do? ==
  
−
This is a compilation of ideas from ML. Needs to be refined (more detailed description, deliverables, workload estimation?):
+
Welcome! Here is a quick list of things to do:
  
−
== List of Ideas for the Project ==
+
* '''MOST IMPORTANT:''' Submit your application to [https://www.google-melange.com Google] before '''March 21st'''.
 +
* '''MOST IMPORTANT:''' Join our IRC channel, '''#wesnoth-dev''' on irc.freenode.net ([http://webchat.freenode.net/ webchat]), and talk about your project and your application. We will not give formal interviews, but we will clearly favor people we have learned to know during the selection process. IRC is the main, mandatory communication medium for the Battle for Wesnoth Project; for the same reason, it's also a good idea to regularly read the [http://www.wesnoth.org/irclogs/2014/ IRC logs].
 +
* '''VERY IMPORTANT:''' Create a wiki page about your idea, using our '''[[SoC2014 Template of Student page|student proposal page template]]''' as base.
 +
** To create a new page, enter the desired URL for the page in your browser's address bar, e.g. <code><nowiki>http://wiki.wesnoth.org/New_Page</nowiki></code>. (See also http://www.mediawiki.org/wiki/Help:Starting_a_new_page)
 +
** Go into editing mode on the template page http://wiki.wesnoth.org/index.php?title=SoC2014_Template_of_Student_page&action=edit and copy the contents to your new page. '''DO NOT ACTUALLY EDIT ANYTHING IN THE TEMPLATE!'''
 +
** Fill the questionnaire.
 +
** Describe and explain your idea in as much detail as possible. Look at other student pages, and provide a timeline, milestones, and studies you've done.
 +
* If you haven't done so yet, create an account on [https://github.com/ GitHub]. ('''Required''' for pull requests and for granting you commit access to the main repository later on.)
 +
* If you haven't done so yet, create an account on [https://gna.org/ Gna.org], where our [http://bugs.wesnoth.org/ bugs tracker] and [https://mail.gna.org/listinfo/wesnoth-dev developers mailing list] are hosted. ('''Recommended''' for submitting bug reports with a single identity, '''required''' for managing bug reports if you are granted commit access.)
 +
* If you haven't done so yet, create an account in the [http://forums.wesnoth.org/ Wesnoth.org forums], and tell a leader of the [http://forums.wesnoth.org/memberlist.php?mode=group&g=6644 Summer of Code group] or a forum administrator on the IRC channel to give it SoC group membership.
 +
** Forum administrators: Ivanovic, Noy, shadowm, Soliton, Turuk
 +
** SoC group leaders: AI, Crab, mordante/SkeletonCrew, thunderstruck, Trademark
 +
* Though not mandatory, it is '''highly advisable''' to take a look at the [[EasyCoding]] and [[NotSoEasyCoding]] pages and implement one of the proposed ideas ideas (or any idea of similar scope) so we can have an idea of how you work. Be sure to use your GitHub account when submitting pull requests so we know who it is coming from. You can also implement features from our [http://bugs.wesnoth.org/ bugs tracker].
 +
** This should give you a good idea what the Wesnoth source code is like and help you get used to our coding style as well.
 +
** When you implement something, also list it on your own page with a reference to the pull request.
 +
** You can also start working on your project and submit patches/prototypes related to it.
 +
* For working on Wesnoth you '''must''' be able to compile Git master. See our [[WesnothRepository|repository information page]] and the guide on [https://github.com/wesnoth/wesnoth/blob/master/INSTALL.md Compiling Wesnoth].

=== Writing an AI based on the formula AI ===
+
== Information about our Project ==
 +
The information we provided Google with about our project can be looked up at the site [[SoC Information for Google]].
  
−
Wesnoth has always had a simple C++ based AI. David (our lead developer) has been working on a simple language to write AI in Wesnoth ''link to formula AI page here''
+
Also see the [[DeveloperResources|Developer Resources]] listing (linked from the [[Project]] page).
−
 
 
−
The Wesnoth AI is used as an opponent in most campaigns, and as such is an important piece of code for the Wesnoth project. Unfortunately it is also one of the most neglected piece of code and a place where a lot of research and work could be done
 
−
 
 
−
==== General description ====
 
−
 
 
−
The aim of this project is to develop a new AI that would replace the original C++ AI. The main criterias we would want for this new AI are
 
−
 
 
−
* ''Plugability :'' It should be trivial for any content maker to change the behavior of the AI in specific case. The exact cases are still to be defined but should typically include
 
−
** hardwiring the first few turns of the AI
 
−
** changing the recruitment pattern
 
−
** completely controlling a given unit (scenario unit)
 
−
** taking control then giving back control of a given unit
 
−
* ''tunability :'' It should be easy for a scenario author to specify the general behaviour of the enemy on a given scenario (aggressiveness, intrepidity...)
 
−
* ''specific behaviours :'' there are some typical behaviours that are not smart to win the scenario but are needed, such as guarding a given unit, a given position, wandering aimlessly, attacking randomly, always fleeing. The AI should implement such behaviours, and allow easy addition of new behaviours
 
−
 
 
−
==== Required knowledge and talent ====
 
−
 
 
−
* ''A minimal knowledge of C++ is required, a good knowledge of C++ is desired :'' The formula AI framework is a work in progress and chances are high that some changes in the wesnoth code base will be needed. The wesnoth developer community is used to handle people that are familiar with coding but not C++, however the Formula AI framework uses advanced C++ features and a good knowledge of the language would avoid a major hurdle when plugging in new entries or functionalities for the AI
 
−
* ''Good social interaction with a large player community :'' A preliminary phase to coding any AI is to know the strategies and game pattern used by human players. This requires huge interaction with the player community. Our Gameplay Developers are open and can give some good starting points, but a big game experience and good interaction with the player community will greatly help in the study of the design
 
−
 
 
−
==== Milestones and deliverables ====
 
−
 
 
−
It is hard to give milestones at this point, but here are some ideas of what could be done
 
−
 
 
−
* ''AI design description, and basic function library :'' This first deliverable aims to conclude the '''study and analysis''' part of the project : becoming familiar with the formula language, study of multiplayer strategies and of the need of scenario writers with regard to AI. We would like to have a description of the code structure of the AI, some basis of the play strategies it would use and how external scenario writers could configure it for the particular behaviour they need
 
−
* ''Main AI delivery :'' This milestone's aim is to deliver a working AI implementing the strategies described in the first phase. It would not have to systematically beat the standard C++ AI at this point, but should be able to play the game correctly (recruit, early deployment on villages, grouping units to attack, holding its ground, protecting weak/important units). Moreover most plug-in entries should be available and a test-case for these entries should be provided.
 
−
* ''Fine tunning and behaviour library :'' The third phase would validate the actual strategy of the AI. The AI should consistently beat the default C++ AI, and do fairly well against an average human player. At that stage a library of scenario behaviours should also be delivered. The AI does not need to be as efficient with all scenario tweaking, but should act correctly with regard to the particular behaviour desired.

=== Extending the Multiplayer server ===
 
−
 
 
−
When the development team met at FOSDEM, we had our multiplayer community, though it is strong and healthy, had its growth restrained by the interface of the multiplayer lobby.
 
−
 
 
−
==== General Description ====
 
−
The general idea of this project would be
 
−
* To study the current lobby,
 
−
* To present some ideas of evolutions both in interface and functionalities of our multiplayer interface to allow it to scale to a much larger community
 
−
* To present some well constructed thought on our MP community and how that interface would develop it
 
−
* Of course to implement those changes :)
 
−
 
 
−
Some ideas that we had (but that are in no way mandatory)
 
−
* Having a simple way to register and authenticate nicknames, similar to what IRC offers. The point is not to have cryptographically safe logins, but to have something simple that gets the job done
 
−
* Having a simple room system? again inspired on IRC
 
−
* Having some way to find the type of games you are interested in.
 
−
** game type
 
−
** number of free slots/players
 
−
** any other criteria you might find interesting
 
−
 
 
−
Other ideas we are not convinced are good, but that are certainly worth studying (especially how the communities based around these concepts are different from ours)
 
−
* ranking players
 
−
* guilds
 
−
* official tournaments
 
−
* titles for players
 
−
* metaservers
 
−
* game matching when players are ranked (poker, bridge...)
 
−
 
 
−
The scalability of the project, both in term of number of players, and in term of the possibility for players and developers to extend the concept will be a valued criteria
 
−
 
 
−
Administration/moderation problems and techniques should also be studied
 
−
 
 
−
interaction with the Add-On server/forum might be an interesting field to expand to
 
−
 
 
−
==== Required knowledge and talent ====
 
−
 
 
−
* A fair amount of experience on C++ is required. Wesnoth uses some advanced C++ features and is heavily based on BOOST and STL. We can train you in some of the libraries used, but learning all of them would be a big hurdle
 
−
* Various experience with multiplayer games, in order to have a good idea of what multiplayer lobbies of other game look like, and (more importantly) a good idea of the social behaviours of multiple MP communities, how teams are formed in games and things like that
 
−
 
 
−
==== Milestones and deliverables ====
 
−
 
 
−
* A first milestone would be a presentation summarizing the different studies, and the proposed interface. preliminary informal stages would probably be desirable, to make sure the proposed idea is already a consensus within devs
 
−
** Study of other MP game-matching interfaces and functionalities
 
−
** Study of other MP communities
 
−
** Study of other MP moderation practices
 
−
** Study of the Wesnoth MP community, including needs, various opinons from different developers and players
 
−
* A second milestone would be the main code delivery. Code should be functional for it will be delivered in the next Wesnoth development release
 
−
 
 
−
=== Scenario/Campaign editor ===
 
−
 
 
−
Currently, in order to create campaign or multiplayer scenarios, it is necessary to manually edit WML files - XML-like configuration files. The goal of this project would be to create a graphical editor allowing the same.
 
−
 
 
−
==== General description ====
 
−
 
 
−
A scenario editor for Wesnoth supporting everything possible by Wesnoth's engine would be a huge project, so the scope of the actual project would of course be limited - what exactly should be implemented would be decided by initial discussion. Implementation details and choice of language/tools would also be up to the student to choose. The main ideas would be for the scenario editor to be:
 
−
* cross-platform (at least Linux, OSX, Windows)
 
−
* easy to use (someone who tries reasonably hard should be able to create a simple scenario/campaign with it, even if not knowing WML)
 
−
* powerful (there already is a map editor coming with Wesnoth - the scenario editor will provide more/different things)
 
−
* extensible (also after the SoC project, it should be easy to add additional features)
 
−
 
 
−
There exist at least two attempts at a scenario editor, an OSX-only one which shipped with early Wesnoth versions, and CampGen, an external tool written in WxPython. The student could look at them for ideas or even use one of them as base, but that should be discussed first. The below assumes a new application is developed from scratch (which likely will be much more motivating for the student than reviving an existing attempt). The actual things to be done would be:
 
−
 
 
−
* Decide on a cross-platform GUI which would be best suited (Qt4, Wx, GTK, Wesnoth's builtin GUI (in that case, could maybe integrate with the existing map editor, but would have serious other problems), or others...).
 
−
* Decide on a platform/language to use (C++, Python, or others...). Wesnoth is written in C++, so it's what most developers would prefer, but as long as it can be expected to work on Linux, OSX and Windows, this is completely open.
 
−
* GUI design. This is the main part of the project. The editor should make it easy to create scenarios, so the GUI must not be confusing/hard to use.
 
−
* Decide on base features. [[ReferenceWML]] lists everything currently supported by WML. Theoretically, the scenario editor could support everything, but for the timeframe of the SoC project, it will be necessary to decide on the most important features and implement those.
 
−
** WML-centric or not? Two opposite views for such an editor would be to either strictly follow WML, as extreme case have one dialog for each WML element. Or on the other hand make a scenario creation tool which completely hides WML and then simply can export to WML, translating features as necessary. The final design likely would be somewhere in between.
 
−
** Ability to read existing WML? The editor will export to WML, but need to decide if it also should be able to read it.
 
−
** Built-in map editor? Wesnoth comes with a map editor, but it can only be used to define the terrain. The scenario editor has to allow placing events and units and other things, so it will need a way to display maps as well. Would be worth investigating if the existing C++ map-drawing code of Wesnoth can be re-used.
 
−
** Ability to enter custom WML code? For advanced users this might be nice, if it can integrate well.
 
−
** Story screen editor for campaigns?
 
−
** How powerful should the events editor be? WML basically is a turing complete language, so must decide what should be supported and how to present to the user.
 
−
** Custom unit animations?
 
−
** Custom multi-hex terrains?
 
−
* Extensibility (leave the possibility to extend the application with plugins for some of the above things, either with a plugin architecture or by making the source code modular enough)
 
−
* WML-export. The second major part besides designing and implementing all the GUI will be exporting the result to WML, and depending on some design choices this could prove more or less hard to do.
 
−
 
 
−
==== Required knowledge and talent ====
 
−
* Knowledge of C++. Even in case the editor is not written in C++, it will be necessary to look at some parts of Wesnoth's source code (WML-parser, editor, ...) and understand them, possibly even integrate/re-use them.
 
−
* Ability/interest in GUI/application design. A not negligible part of the project likely will be spent designing various GUI dialogs.
 
−
* Prior use of level creation tools/modding tools. Knowing existing tools for other games will help a lot in the design phase, as many good ideas can be seen there. Not required though.
 
−
* Having played Wesnoth and knowing what scenarios look like would help. Someone who never played Wesnoth before would risk losing a lot of precious time playing the game instead of working :) But it's not required of course.
 
−
* Knowledge of WML. A candidate who already knows Wesnoth's WML could save the initial time studying it. (On the other hand, not knowing WML might mean less technical bias and might lead to an application which is easer to use for non-technical users.)
 
−
* Ability to interact with developers/users. Presenting GUI mockups and test versions and incorporating early user feedback likely will improve the end result a lot. The Wesnoth community is big enough that there should be quite some willing testers.
 
−
 
 
−
==== Milestones and deliverables ====
 
−
The initial design will decide on many later things, and likely a lot of talking to developers and users will be necessary. But some general milestones I'd expect:
 
−
* Create a base test application in the chosen language/platform. This will not do much yet, maybe load some WML and display it as text. Try to package it for Linux, OSX and Windows (there will be help from the Wesnoth community, so no need to have access to all of them), and see if it can be expected to work. If a standard GUI like C++/Qt4 is used, this will be rather trivial. Something like Python/Wx or C#/.NET might take more time.
 
−
* Add ability to edit some very simple, maybe only textual properties of a scenario, and export to WML. It should already have base features like Save/Load/Undo, copy/paste, multiple documents, and so on. Depending on the chosen GUI this may be easy or already require some work.
 
−
* Finish design. Should list the intended features and demonstrate how the GUI will work.
 
−
* Start implementation, a natural milestone would be to make it possible to create and export a very simple, but playable scenario.
 
−
* Add more of the features (which ones and in which order depends on the design above, a detailed roadmap will be part of it).
 
−
 
 
−
=== Addon server ===
 
−
Wesnoth has an addon server which offers users to upload user
 
−
made content (UMC). This allows all other users of Wesnoth
 
−
to easily download and install this content. The server was
 
−
originally written for user made campaigns but contains a lot
 
−
more types of addons nowadays. Both the server side and the
 
−
client side need to be improved.
 
−
 
 
−
==== General description ====
 
−
Both the server and client side of the addon server haven't
 
−
been improved over the years and can use quite some improvements.
 
−
The client side GUI needs quite some improvements. For the
 
−
server side it's wanted to allow better integration with
 
−
various tools, which improve the quality of the addons.
 
−
 
 
−
===== Server side =====
 
−
The server code either needs to be updated or rewritten, the
 
−
student is free to make this decision him or herself. The
 
−
student is free to choose the language for the server.
 
−
 
 
−
* The server only needs to run on Linux systems, crossplatform would be nice but isn't  required.
 
−
* At the moment there's a rudimentary integration with our translation project Wescamp. This needs to be improved. Upon uploading the new content needs to be send to Wescamp (via a svn commit). And the translations need to be fetched on a regular basis.
 
−
* We have various tools to check the WML code and also upgrade it to newer version. The addon server needs to be able to run those tools on the content.
 
−
 
 
−
===== Client side =====
 
−
The client side needs improvements, there are two main clients
 
−
the ingame version and a standalone version in Python.
 
−
 
 
−
* Upgrade the GUI, Mordante is working on a new GUI library which is intended to make it possible to make the wanted changes.
 
−
* Make it easier to see what kind of addon it is, at the moment a lot of new users download something and have no clue what kind of addon it is.
 
−
* Make it easier to see whether a newer version of the addon is on the server and update the addon.
 
−
* Make it easy to select which translations you want to download and also look for newer versions of the translations.
 
−
 
 
−
====  Required knowledge and talent ====
 
−
* Knowledge of C++, the game is written in C++ and modifications need to be made there.
 
−
* Knowlegde of Python, various tools have been written in Python which need to be intergrated with the new server.
 
−
 
 
−
==== Milestones and deliverables ====
 
−
* The first step is to determine what exactly needs to be done and determine in which language the server will be rewritten. This includes, but isn't limited to:
 
−
** Determine the exact feature set.
 
−
** Protocol changes needed.
 
−
** Methods to integrate with both the WML tools and Wescamp with the new server.
 
−
** Determine the GUI for the client side.
 
−
* This needs to be presented and discussed with the mentor(s).
 
−
* The next thing in to implement the feature set. The code needs to be fully functional and committed in trunk.
 
−
 
 
−
=== Map editor ===
 
−
The map editor in Wesnoth serves two goals, making it easy to create
 
−
a new map and helping the terrain artists to test their new terrains.
 
−
 
 
−
==== General description ====
 
−
The current editor hasn't been actively maintained for quite a while and the
 
−
quality of the code isn't up to par with the main game. The student
 
−
will either revive the current editor or start from scratch, the latter
 
−
will probably be easier. When rewriting from scratch the student can
 
−
pick the language of his/her liking as long as the result is crossplatform
 
−
(at least Linux/Windows/OS X).
 
−
 
 
−
Some of the things the new/revived editor should be able to do:
 
−
* Include all features of the current editor.
 
−
* When rewritten, great care must be taken that the render engine works the same as the render engine in the main game. When rewritten in C++ it can simply use the game sources, otherwise the student needs to turn the main game C++ files into a library which can be called in the language the editor will be written in.
 
−
* The editor needs to be able to handle so called ''custom terrain'', these are terrains used in maps but not loaded by default.
 
−
* The editor needs to be able to reload the terrain graphics config files, this way terrain artist can test the changes to the config files without having to reload the editor.
 
−
* The current editor can generate random maps with help of a config file, which contains a generator definition. The editor can only use one generator hardcoded. This needs to be modified to be able to use every generator config the user has installed.
 
−
* Various ideas exist to help the artists to make it easier to tune their terrains and config files, this is a secondary goal. We think it will be too much work to do this in one summer.
 
−
 
 
−
==== Required knowledge and talent ====
 
−
* The current editor and the main game are written in C++ therefore knowledge of C++ is required. Even if the editor is rewritten in another language the render engine needs to be converted to a library.
 
−
* The student needs to be able to make a user friendly user interface.
 
−
* Depending on in which language and toolkit the editor is (re)written in the student will need to have skills in that language and toolkit. The current editor uses the SDL toolkit with our own widget toolkit.
 
−
 
 
−
==== Milestones and deliverables ====
 
−
* The first step is to determine which features are wanted. This means the student has to interact with the community and determine what is wanted.
 
−
* From this list the student needs create a list of items he/she will be able to do within one summer.
 
−
* This needs to be presented and discussed with the mentor(s).
 
−
* The next thing in to implement the feature set. The code needs to be fully functional and committed in trunk.
 
−
 
 
−
=== Make your own ideas ===
 
−
If you have your own idea the best thing is to join IRC wesnoth-dev at irc.freenode.net and discuss the idea with the developers there. If the developers think your idea is interesting and like the feature you can start to turn it into a full proposal. Once done discuss it again on IRC so the developers can accept your idea.
 
−
 
 
−
=== Other ideas to be fleshed out ===
 
−
* A MapGenerator rewrite - better scalable for outdoor maps, plus the possibility to define areas (similar to the caverns in the ave generator) etc.

==== Describe your organization. ====
 
−
The Battle for Wesnoth, or simply Wesnoth, is a free turn based strategy game with role playing elements designed in June 2003 by David White (Sirp).
 
−
 
 
−
The first stable release (1.0) was on October 2 2005, the latest stable release (1.4) was on March 8 2008.
 
−
 
 
−
add some info from http://www.ohloh.net/projects/3175
 
−
 
 
−
* A turn­based strategy game
 
−
* On a hexagonal board
 
−
* Role playing game style elements
 
−
* Single player and multiplayer modes
 
−
* Runs on a variety of platforms
 
−
* Highly customizable and 'moddable'
 
−
 
 
−
What makes Wesnoth stand apart from the other open source games are the following aspects
 
−
 
 
−
* A large developer and player community
 
−
** two servers (stable and developement) with more than a hundread players at all time
 
−
** more than two thousands downloads a day
 
−
* A mature project, but with active development and many improvements
 
−
* High quality artwork: both graphics and music
 
−
* Very well­balanced by a tireless team of playtesters
 
−
* Fun, unique gameplay
 
−
 
 
−
The general [http://www.wesnoth.org/wiki/WesnothPhilosophy Philosophy] of the game (both for gameplay and coding) puts en emphasis on simplicity. The core rules are meant to be learnt easily but provide interesting gameplay and diverse strategies.
 
−
 
 
−
On the other hand, Wesnoth scenarios provides a simple language to easily customize scenarios, which has lead to a huge modding community providing us with a wide amount of content.
 
−
 
 
−
* Advanced C++, with some use of Boost
 
−
* The Simple Directmedia Layer (SDL) libraries:
 
−
* SDL, SDL_net, SDL_ttf, SDL_image
 
−
* gettext for internationalization
 
−
* Python to allow scriptable AIs
 
−
* Otherwise, most of Wesnoth's technology is “home grown”:
 
−
** WML : the scripting language used to write scenarios
 
−
** FormulaAI : our AI developement language
 
−
 
 
−
* 2.1 million downloads via sourceforge.net, many more via various mirrors of Linux Distributions
 
−
* best rated game at the [http://www.happypenguin.org/list?sort=avg_rating linux game tome]
 
−
* game of the year 2007 at [http://www.linuxquestions.org/questions/2007-linuxquestions.org-members-choice-awards-79/open-source-game-of-the-year-610236/ linuxquestions.org]

==== Why is your organization applying to participate in GSoC 2008? What do you hope to gain by participating?====
 
−
 
 
−
Most of our developers have particular areas of interest in which they work. Though they are efficient in their areas, there are other, presently uncovered, areas of the code with a need for improvements but a high barrier to entry.
 
−
 
 
−
If a student were dedicated to any of these uncovered areas, we believe that person could be brought up to speed relatively quickly and function as a peer of the existing developers.
 
−
 
 
−
By bringing new people in and allowing them to be actively responsible for an area of code, we hope to kickstart some areas of the project that have lagged behind
 
−
 
 
−
==== Did your organization participate in past GSoCs? If so, please summarize your involvement and the successes and challenges of your participation.====
 
−
This is the first time the Wesnoth project has applied to Google SoC.
 
−
 
 
−
==== If your organization has not previously participated in GSoC, have you applied in the past? If so, for what year(s)?====
 
−
 
 
−
This is the first time the Wesnoth project has applied to Google SoC.
 
−
 
 
−
==== Who will your organization administrator be? Please include Google Account information.====
 
−
Nils Kneuper aka Ivanovic
 
−
 
 
−
crazy.ivanovic |ATTT| googlemail.com
 
−
 
 
−
==== What license(s) does your project use?====
 
−
Our project is entirely GPL.
 
−
 
 
−
All code is GPL.
 
−
 
 
−
All art is GPL, 99% was made for the project, everything else was taken from content that was checked to be GPL.
 
−
 
 
−
==== What is the URL for your ideas page?====
 
−
Our main summer of code page is located at http://www.wesnoth.org/wiki/SummerOfCodeIdeas
 
−
 
 
−
This page contains various coding ideas and the thought the development team has already given them.
 
−
 
 
−
It also contains a list of the developers that are the most active on IRC and their domains of interest.
 
−
 
 
−
==== What is the main development mailing list or forum for your organization?====

Most development work takes place on "wesnoth-dev |ATTT| gna.org". Beside this some work happens at http://www.wesnoth.org/forum/.
 
−
 
 
−
in particular, all art developement takes place on the forum.
 
−
 
 
−
==== What is the main IRC channel for your organization?====
 
−
 
 
−
All our IRC channels are on the ''freenode'' network
 
−
 
 
−
* ''#wesnoth-dev'' is the main development channel, where most discussion takes place
 
−
* ''#wesnoth'' is a generic channel for the community
 
−
* ''#wesnoth-mp'' is a separate channel for multiplayer games and balancing
 
−
 
 
−
==== Does your organization have an application template you would like to see students use? If so, please provide it now.====
 
−
We plan mainly to meet potential students through our IRC channel, but the following questions are wesnoth-specific and are worth pondering for any student, even if we don't need a formal answer
 
−
 
 
−
* What type of gamer are you? What type of games? What type of opponent? Are you more interested in story or gameplay?
 
−
* Are you good at interacting with other players? Our developer community is friendly, but the player community can be a bit rough.
 
−
* Do you give constructive advices? Do you receive advice well? Are you good at sorting useful criticism from useless ones?
 
−
* Have you played Wesnoth? How long?  Single player or multiplayer? We do not plan to favor Wesnoth players as such, but some projects require a good feeling of the game which is hard to get without having played intensively.
 
−
* What nickname do you plan to use on IRC and the forum?

David White (davewx7@gmail.com)
 
−
 
 
−
Jeremy Rosen alias Boucman (boucman2|ATTT|gmail.com)
 
−
 
 
−
Mark de Wever aka Mordante (mordante.wesnoth|ATTT|gmail.com)
 
−
 
 
−
==== What criteria did you use to select these individuals as mentors? Please be as specific as possible.====
 
−
 
 
−
Our first criterion was that all the people had to be volunteers. According to other open source projects, being a SoC mentor takes a lot of time and the person has to be ready to spend quite some time with the student
 
−
 
 
−
Dave is the project leader and one of the most knowledgeable in C++. He has also written the Formula AI code which we plan to develop via the SoC. He is well known in our community for formulating simple but effective explanations for complicated topics, and has good design intuition. The growth of Wesnoth demonstrates his capacity to get other developers to work together and keep them involved in a thriving community.
 
−
 
 
−
Boucman is one of the oldest active developers around. He has rewritten the whole animation engine and made it an easily pluggable system allowing artists to easily specify exactly how they want the units to appear. He also started many community oriented projects like the [http://wiki.wesnoth.org/UnsortedContrib Art Contribution] section of the wiki (now automated) and the [http://wiki.wesnoth.org/ReferenceWML WML Reference Manual]. He is responsible for dispatching and sorting the patches at [http://patches.wesnoth.org] and has created the new developer process we currently use.
 
−
 
 
−
Mordante is one of the most active developers on our IRC channel. Not only has he done preliminary studies and coding in multiple areas that are candidates for Summer of Code ideas, he also is one of the coders with the best overview of the Wesnoth code.
 
−
 
 
−
All other developers listed in the ideas page are the leading capacities we do have for the respecting areas. Have a look at our list of people who to contact for which regards. In general all our developers will mentor all students. That is, questions should just be asked in our IRC channel, where basically every developer who has an idea can directly answer.
 
−
 
 
−
When choosing the mentors, we have kept in mind that most developers can answer most technical questions, and we have chosen people that are well known for interacting with new-comers/external developers and can provide general guidance and design advice, more than people with specific technical knowledge.
 
−
 
 
−
==== What is your plan for dealing with disappearing students?====
 
−
The first thing to do is to avoid this situation altogether.
 
−
 
 
−
Wesnoth is a game, and as such have lots of developers that are not coders. In particular, artists are well known in the wesnoth community for being very sensible about criticism and our community is used to people being sensible to critics.
 
−
 
 
−
We will try to choose students that accept criticism and are able to filter constructive criticism from useless ones. The wesnoth developper community is used to juging people according to these criterias and the special title we are going to give to applicants will allow us to easily spot any such problem and discuss them before the grow out of control.
 
−
 
 
−
 
 
−
If a student disapears, his mentor will be in charge of recontacting him to see what is going wrong (available time, tension with other developers, with members of the community etc...) depending on the actual problem, the mentor and the student will have to agree on possible ways to defuse the problem.
 
−
 
 
−
If a student disapears completely and there is no way to get back to him, there is little the project can do except slvaging whatever can be slavaged from the code (the students will have SVN write access, so most of the work will be commited either to trunk or to a specific branch) and find a core developper to take on the job. This will probably slower and less effective for the project, but it's the best we can do.
 
−
 
 
−
==== What is your plan for dealing with disappearing mentors?====
 
−
 
 
−
==== What steps will you take to encourage students to interact with your project's community before, during and after the program?====
 
−
 
 
−
Wesnoth has a particularly healthy community, both for developers and for players.
 
−
 
 
−
Our general policy regarding new coders has always been "two patch... you're in" In other word, anybody that is able to get two non-trivial patches applied is offered commit right.
 
−
 
 
−
We have a developer responsible for applying patches and guiding new developers into our community. This is a well known and effective process we plan to apply to students, directing them to our [[EasyCoding]] pages (these project are usually a couple of hours long and has been chosen to provide easy access to code)
 
−
 
 
−
Usually, patches go back and forth a couple of time, to make sure that all secondary things are in place (indenting, coding style, modified makefiles etc.) The idea is that coder education should take place before the coder gets commit rights, but that getting new coder in is one of the most important things to maintain our project alive.
 
−
 
 
−
If the student is a little proactive and ready to join IRC, all the developers are usually very welcoming, and good at directing newcomers to quickly give useful results.
 
−
 
 
−
We also plan to give a special forum title to any students. This will allow all forum members to tell them apart from normal users and give them read/write access to the developer only forums. This will also allow us to quickly spot any problem they might have interacting with the player community. We have a very mature developer community, but our player community is made of all sort of people of all age and education, and it can be rough at time.
 
−
 
 
−
==== What will you do to ensure that your accepted students stick with the project after GSoC concludes?====
 
−
 
 
−
Since our community has a history of having developers easily and quickly join, we expect the student to be full-fledge developers quite faset (probably a little after the end of the bonding period).
 
−
 
 
−
Thus there will be no "end of GSoC" transition. At the end of the Summer of code we expect the student to be responsible for the part he developed, and to continue taking care of it, like other developers are responsible for their part.

Contents

I want to be one of your Google Summer of Code students, what should I do?

Welcome! Here is a quick list of things to do:

  • MOST IMPORTANT: Submit your application to Google before March 21st.
  • MOST IMPORTANT: Join our IRC channel, #wesnoth-dev on irc.freenode.net (webchat), and talk about your project and your application. We will not give formal interviews, but we will clearly favor people we have learned to know during the selection process. IRC is the main, mandatory communication medium for the Battle for Wesnoth Project; for the same reason, it's also a good idea to regularly read the IRC logs.
  • VERY IMPORTANT: Create a wiki page about your idea, using our student proposal page template as base.
  • If you haven't done so yet, create an account on GitHub. (Required for pull requests and for granting you commit access to the main repository later on.)
  • If you haven't done so yet, create an account on Gna.org, where our bugs tracker and developers mailing list are hosted. (Recommended for submitting bug reports with a single identity, required for managing bug reports if you are granted commit access.)
  • If you haven't done so yet, create an account in the Wesnoth.org forums, and tell a leader of the Summer of Code group or a forum administrator on the IRC channel to give it SoC group membership.
    • Forum administrators: Ivanovic, Noy, shadowm, Soliton, Turuk
    • SoC group leaders: AI, Crab, mordante/SkeletonCrew, thunderstruck, Trademark
  • Though not mandatory, it is highly advisable to take a look at the EasyCoding and NotSoEasyCoding pages and implement one of the proposed ideas ideas (or any idea of similar scope) so we can have an idea of how you work. Be sure to use your GitHub account when submitting pull requests so we know who it is coming from. You can also implement features from our bugs tracker.
    • This should give you a good idea what the Wesnoth source code is like and help you get used to our coding style as well.
    • When you implement something, also list it on your own page with a reference to the pull request.
    • You can also start working on your project and submit patches/prototypes related to it.
  • For working on Wesnoth you must be able to compile Git master. See our repository information page and the guide on Compiling Wesnoth.

Information about our Project

The information we provided Google with about our project can be looked up at the site SoC Information for Google.

Also see the Developer Resources listing (linked from the Project page).

People to bug on IRC

We have prepared a list of people with their areas of competence. This should give you an idea of which areas those people can help you with. Of course you should always ask in the IRC channel first, but these are the most likely people to be able to help you.

List of Ideas for the Project (Suggestions from Wesnoth developers)

Note: This list of ideas is automatically generated from the Description section of pages in the Summer of Code 2014 Idea category. DO NOT TRY TO EDIT THIS LIST BY HAND - IT WON'T WORK. Instead, create a new page using the GSoC idea page template.
Note: To add a student page, create a new page copying the contents of the student proposal page template.


AI: Improve AI by implementing global attack/retreat decision

Page for the idea: SoC_Ideas_AI_Global_strategy

The Wesnoth AI works by making local decisions about moves and attacks. Teach it to determine if it's worth to fight offensively or defensively in a given situation.


There are 5 submitted student proposals for this idea

Aditya Pande - Global AI for Battle of Wesnoth

I propose to implement global AI using a combination of idea of Quiescence search on game tree with alpha beta pruning along with a few heuristics to make it possible to actually solve this complex game. Also this approach requires an evaluation scheme for the same.

The idea of using Quiescence search here is different than that in chess engines. Here my idea is to reduce the average branching factor for each choice made by considering the ones which do not affect the game drastically (hence called quiet moves). In this case the braching factor for a unit can be given by 

braching factor=Number of attacking moves + Number of Acquire village moves + 2

The 2 represent all Quiet moves based on retreat or charging forward towards enemy. As the quiet moves above do not affect the game drastically they shall be decided based on heuristics and here I plan to only consider the greatest retreat/charge.

The idea behind my approach is based on "Wesnoth can be treated much like a continuous game, because many positions tend to be very similar to each other. Additionally, unlike discrete board games, it is not common that a very small wrong move in Wesnoth is disastrous."

The aim of the whole approach is to simplify the game complexity using few heuristics and then use approach of negamax to select a good overall global move(not the best because of the simplication done) . Also the number of attacking moves and number of acquire village moves has to be reduced to actually keep the problem solvable. (Read all the heuristics for the same in Technical description).

I also plan to divide the whole problem into independent parts whenever possible. Let me give an example, lets say that the AI is under attack on 2 fronts but there is (currently) no relation between the 2 as to say that the AI units involved can't interact(i.e they are too far and can't 'get close' to each other in next turn). My idea is that by doing such division and focusing on solving each problem individually sharply reduces the complexity of the problem.

Lastly I plan to adopt some ideas from Fuzzy Logic, FSM and Behaviour trees to improve the current model I propose.
See Aditya Pande Global AI for more information.

Vahen_Improve_AI

I would like to improve the AI by implementing Global attack / retreat decision.

Elements : Anything around the unit that can cause a change to the behavior

Behavior : Determine what the enemy is going to do based on the elements.

Deliberation : Does the best move depending on the behavior previously set .

To do so I will use probality theory to determine what is best move to do.
See Improve AI for more information.

Arveanor Global AI

Give an ai player a set of potential objectives to pursue such as taking a village, killing an enemy, defending a village etc. Also give each ai different behavior modes based on the information they have access to. i.e. fight aggressively, fight defensively, fight cautiously etc. The ai would, depending on it's current behavior mode pursue the objectives more or less rigorously depending on how they align with the current behavior.

The behaviors and objectives would not necessarily mix strongly with recruitment, however a similar system to what would analyze which behavior to be used would also be able to inform recruiting patterns. Obviously certain unit types and a large amount of certain terrain hexes give good reason to favor certain units in recruitment, of course gaining vision and taking outlying villages (i.e. AI global objectives) would play into recruitment in terms of recruiting faster units.

Improve the automated collection and display of multiplayer game data

Page for the idea: SoC_Ideas_Multiplayer_Data_Analysis

Multiplayer games are currently archived. This includes lots of interesting and potentially useful data, including recruits, deaths, number of turns and other things. The only way to access this information currently is parsing the WML one save file at a time. Additionally, which side(s) won the game is only recorded in some cases. We would like to record which side(s) won or lost (for as many games as possible) and then display useful information about these games for balancing and feedback purposes.

There is 1 submitted student proposal for this idea

Sachith Seneviratne - Multiplayer Data Analysis Proposal

Although Multiplayer games are being archived currently, no data is saved regarding the winner(s). Recording and presenting this information would allow for easier balancing and feedback for content creators. Specifically, this project will add a means by which players can indicate who won, as well as parse the saved data and store in a database as much useful information regarding the games as possible.


See GSoC sachith500 Proposal for more information.


SDL2

Page for the idea: SoC_Ideas_SDL2

The Wesnoth project uses the SDL library. Last year, a new major version (2.0) of SDL was released. This version of the library has better support for mobile devices like the Android and the iPhone. This project involves helping porting Wesnoth from SDL 1.2 to 2.0.

There are 5 submitted student proposals for this idea

Ben Kenawell - SDL2 Project Proposal

Descriptive Summary of Proposal
I would like to work on moving the event and input handling from SDL 1.2 handling to SDL 2.0. To accomplish this I will be considerate of the many differences between the versions including how text input is handled and the differences in event handling. In performing both these tasks, I will be aware of a possible Android or iOS port (since I would love to see that myself), so that my code will perform as smoothly on mobile operating systems as it already does on desktop OSes.

First Level Sections
One major change in event handling is how the thought process behind the keyboard works. The keyboard has become like a many buttoned controller, instead of text inputs. This will be a major change I will work on, in order to make Battle for Wesnoth more keyboard-layout independent. Mouse input will remain similar, except for the mousewheel which, with better support in SDL 2.0, will be more useful for scrolling around the screen. This change may also help with two-finger scrolling across a screen where the comptuer reports this as a mousewheel, ultimately aiding in the creation of a mobile port. Event handling will have similar ideas in mind. While the actual code has not changed very much, those differences will be taken care of as well as a new style of event handler for certain important events, i.e. events that affect the state of the app (open/closed) will be monitored more closely so that progress may be saved. I have taken this into consideration along with the other event handler changes in order to deal with the "garbage collector," which is the nightmare of mobile operating systems. I fear that in the near future (at least with Windows machines), that the garbage collector's presence might make an appearance in desktops, and this measure would increase the longevity of my changes as well as more easily enable mobile ports.
See Dragonofair0/GSoC2014 project idea for more information.

Juan Miguel Ruiz Ladrón, new SDL version

Project description I want to upgrade Wesnoth's SDL 1.2 version to SDL 2.0 version. Specifically the event handling system.


First-level The main problem to move Wesnoth to SDL 2.0 version is the event handling system. I would work with desktop version of the game, improve keyboard input to select actions, units, etc. Also, develop the mobile version of the game, i'm working with Android, using LibGdx framework, i think, it's similar to SDL 2.0 version for handling events and more.
See Juan Miguel Ruiz Ladron/GSoC2014 Proposal for more information.

lipkab - SDL2 transition

I propose to help with the SDL2 transition.

I'd like to work on implementing hardware accelerated rendering for Wesnoth and enabling it for the map/unit rendering system.
See SoC2014 lipkab SDL2 for more information.


See SoC2014 SDL2 DrawingTransition for more information.

TODO: Copy this page and write "your name - proposal title" in this h4 section

TODO: Write a small (1-4 sentences) description of your proposal here.

TODO: Add more first-level sections to detail your proposal
See SoC2014 SDL2 stevedes for more information.


SpriteSheet

Page for the idea: SoC_Ideas_SpriteSheets2014

Wesnoth uses thousands of images, each of them stored in separate files. It would be more efficient to store multiple images in a single file. In order to make that possible, the Wesnoth engine needs to be adapted to allow this change.

There are 2 submitted student proposals for this idea

ALourenco - SpriteSheet

I am proposing the development of a SpriteSheet compability, so the number of assets of Wesnoth can be decreased and it's coding gets cleaner. Instead of having a lot of pictures, we can have, for example, just one per character with all animations needed. It works like a chess board where you can acess the previosly separated pictures in it's respective position. Since Wesnoth uses SDL, we can use OpenGL directly and easily handle several textures from only one SpriteSheet.
See GSoCSpriteSheetsALourenco for more information.

Aishiko GSOC 2014 SpriteSheets

My proposal is to take the current functions for drawing sprites and move it to allow for spritesheets, while hiding any of the changes from campaign designers. It should allow for the seemless intergration of spritesheets and allow for a period of conversion from multiple files to sheets.
See SpriteSheetApplicationSAB for more information.


UMCD

Page of the idea: SoC_Ideas_UMCD_2014 Improving and completing the new add-ons server, UMCD (User-made Content Daemon).

There is 1 submitted student proposal for this idea

Spoffy - UMCD Extension Proposal

I intend to complete and extend the User Made Content Daemon produced by Trademark during GSoC 2013. This means implementing the basic functionality (Uploading, downloading addons, etc) in a secure manner. After this, I would continue on to extend it by adding administration tools, refactoring code, adding build scripts, adding cross-platform support (in principle), and other things (probably!). Outlined on this page is an in-depth proposal

More to come as I fill this out.
See SoC 2014 Spoffy Finishing and Enhancing the UMCD for more information.


Game Engine: Unify SP and MP

Page for the idea: SoC_Ideas_Unify_SP_and_MP_2014

Wesnoth has lots of user made content, but some of it works only for either singleplayer or multiplayer. To solve this, some of the engine's singleplayer and multiplayer code paths need to be unified and extended.

There are 2 submitted student proposals for this idea

RiftWalker - Game Engine: Unify SP and MP

Currently, certain add-on content works only in single- or multi-player games. The purpose of this project is to ensure that all user-made content works across game modes by unifying and extending the code paths that handle configs for single- and multi-player games. This will be achieved by making SP a special case of MP as described by Zaroth.

  • To begin with, I will implement the current single player campaign creation through the multiplayer code path, changing as little as possible.
  • Once I've sorted out all the problems that may arise from this, the door will be open to a host of potential new features and improvements which I will implement according to demand from the community.


See SoC2014 RiftWalker Unify SP MP for more information.

youngoli - Unify SP and MP

Abstract: This proposal is intended to unify the separate code paths responsible for handling configuration files in single player and multiplayer. This will allow content that previously would only work in multiplayer to work in singleplayer as well.
See SoC2014 youngoli UnifySPandMP for more information.


Other: Your own ideas

Page for the idea: SoC_Ideas_Your_Own_Ideas_2014

Suggested skills: C++ (depends on the project).

There are 9 submitted student proposals for this idea

Dugi - Campaign Wizard

I've seen on the forums that people frequently ask for campaign wizards and such and when they're told that there is no such thing, they struggle usually with the basics like writing a proper _main.cfg file. There is a project named Eclipse Java plugin, but it's not a part of wesnoth, only a few people know about it and it is basically just a text editor adapted to work with WML. This project is to make a campaign wizard, incorporated into the game, that would allow creating simpler campaigns in an intuitive way, without having to read or write source codes.

The idea is to create a campaign making GUI that would be accessible from the map editor or some other menu, and would allow making campaigns without writing any codes, just clicking and writing some dialogues, unit names and such. It wouldn't allow doing all the things that can be done with WML, just the more common things.

It would contain several windows or tabs, one for the entire campaign's properties (setting up the basic properties), one for the scenarios (setting up the basic properties, like assigning maps, sides' properties, then adding commonly used events) and something for adding custom units (basic properties, assigning images to attacks and animations).

It would need to use slightly different data structures than usual wesnoth because campaigns need including files and macros, preprocessor defines and similar things that are usually parsed out when reading the files. I think that they could be created through inheritance and a few modifications (especially a special tag for macros and a property to make it depend on difficulty).

The map editor can do a plenty of things around scenarioWML, so it might be used to create scenarios after some editing, but at least some sort of ActionWML editor would need to be added (supporting basic tags like message, creating units, killing units, moving units).

This is what the main window of the campaign editor might look like (sorry for not caring much about the layout's appearance, but that's not the point): 1Y6Og6S.png

Further expansions (if time remains or to be done in another summer) may include support for ifs, variables and objects in ActionWML, AMLA, custom abilities and weapon specials in UnitWML, maybe possible alternative scenario paths.

--LARGE MODIFICATIONS TO PROPOSAL UNDERWAY, INPUT WELCOME--

Due to my particular skill set, working on the eclipse plugin (the UMC editor) would be ideal. Once I manage to acquire a copy of the source code, the project will probably go something like this:

1) (main task) check the wizards that are supposed to exist within the plugin. Make any modifications necessary to keep it up-to-date with WML, then make any changes, additions, or modifications that might be useful to the users. Wizards should include a scenario wizard and campaign main wizard, as these are the most painful to build by hand. Additional components may include a unit wizard, event wizard, and anything else I can think up. Unfortunately, I can't be more specific at this time.

2) (additional task) Check with the original author (Timeotei, I beleive,) and see if there are any things he wanted to include from GSoC 20(11? 12?) and try to implement them. It would be nice to contribute to the original vision.

3) (additional task) Once all other possible tasks have been completed, start a forum thread in the "wml" section and see if anyone has a unique/much needed addition. If they do, I can work on that...

4)...and if they don't, ask the devs for more work. IF my proposal is selected, I see GSoC as a job, and will work like a rabid horse.


I'm still working at convincing eclipse to load the UMC editor properly, and will post additional (much-needed) details as soon as I can.

Thanks for reading,

Improve Random Map Generator

The aim of this proposal is to create better random-generated maps for singleplayer and multiplayer game using new elements and options

Using different "biomas" in the same map (not only desert for example) to make more "unique" scenarios, also, including other elements like peninsulas so the general form of the map changes

AI: Improve AI by implementing global attack/retreat decision

Page for the idea: SoC_Ideas_AI_Global_strategy

The Wesnoth AI works by making local decisions about moves and attacks. Teach it to determine if it's worth to fight offensively or defensively in a given situation.


There are 5 submitted student proposals for this idea

Aditya Pande - Global AI for Battle of Wesnoth

I propose to implement global AI using a combination of idea of Quiescence search on game tree with alpha beta pruning along with a few heuristics to make it possible to actually solve this complex game. Also this approach requires an evaluation scheme for the same.

The idea of using Quiescence search here is different than that in chess engines. Here my idea is to reduce the average branching factor for each choice made by considering the ones which do not affect the game drastically (hence called quiet moves). In this case the braching factor for a unit can be given by 

braching factor=Number of attacking moves + Number of Acquire village moves + 2

The 2 represent all Quiet moves based on retreat or charging forward towards enemy. As the quiet moves above do not affect the game drastically they shall be decided based on heuristics and here I plan to only consider the greatest retreat/charge.

The idea behind my approach is based on "Wesnoth can be treated much like a continuous game, because many positions tend to be very similar to each other. Additionally, unlike discrete board games, it is not common that a very small wrong move in Wesnoth is disastrous."

The aim of the whole approach is to simplify the game complexity using few heuristics and then use approach of negamax to select a good overall global move(not the best because of the simplication done) . Also the number of attacking moves and number of acquire village moves has to be reduced to actually keep the problem solvable. (Read all the heuristics for the same in Technical description).

I also plan to divide the whole problem into independent parts whenever possible. Let me give an example, lets say that the AI is under attack on 2 fronts but there is (currently) no relation between the 2 as to say that the AI units involved can't interact(i.e they are too far and can't 'get close' to each other in next turn). My idea is that by doing such division and focusing on solving each problem individually sharply reduces the complexity of the problem.

Lastly I plan to adopt some ideas from Fuzzy Logic, FSM and Behaviour trees to improve the current model I propose.
See Aditya Pande Global AI for more information.

Vahen_Improve_AI

I would like to improve the AI by implementing Global attack / retreat decision.

Elements : Anything around the unit that can cause a change to the behavior

Behavior : Determine what the enemy is going to do based on the elements.

Deliberation : Does the best move depending on the behavior previously set .

To do so I will use probality theory to determine what is best move to do.
See Improve AI for more information.

Arveanor Global AI

Give an ai player a set of potential objectives to pursue such as taking a village, killing an enemy, defending a village etc. Also give each ai different behavior modes based on the information they have access to. i.e. fight aggressively, fight defensively, fight cautiously etc. The ai would, depending on it's current behavior mode pursue the objectives more or less rigorously depending on how they align with the current behavior.

The behaviors and objectives would not necessarily mix strongly with recruitment, however a similar system to what would analyze which behavior to be used would also be able to inform recruiting patterns. Obviously certain unit types and a large amount of certain terrain hexes give good reason to favor certain units in recruitment, of course gaining vision and taking outlying villages (i.e. AI global objectives) would play into recruitment in terms of recruiting faster units.

neonosos - Improve AI by global world analysis

My goal is to contribute Wesnoth AI by improving AI players with global-analysis skill. This skill makes AI players able to not only react on local impulses (such as attack or presence of another player), but also to make deeper-planned strategies.

Economical aspect
The AI player should be able to decide which enemy to attack according to his economical needs. It means, that if AI player needs gold, he should attack player with high gold resources.
War-strategy aspect
AI player should not attack if it's not appropriate. Why to attack player, that is much stronger than the AI? Maybe some kind of indirect (for example economical, diplomatic) attack would be more appropriate.
Planning for future aspect
Should I attack the nearest enemy's village? Why not to attack the further one, cutting of the escape from the nearest village?

Daniwa: Improve the AI's Attack and Retreat decisions.

Abstract: Implement a process that would allow the AI to make correct decisions in regards to attack and retreat. It will be based off probability focused on current metagame habits.

Proposal: The focus of my implementation is not on outputting the optimal result in every case but instead will aim at mirroring a player like decision. The goal for this is to foster and develop good game decision making in new players and prevent bad habits. Ideally, the AI should act correctly but unpredictably (which is technically impossible) and be able to be a training aid.

Zubin Kapaida: Improve AI by implementing global attack/retreat decision

I believe that the key to making a good AI bot is to keep your ideas clear and simple. One must evaluate the gravity of the situation using the given parameters and accordingly act offensively or defensively.

Sometimes it is more beneficial to risk one unit’s death or even sacrifice a few and perform the attack, the tricky part is to figure out when. In this game “Battle of Wesnoth” several factors affect the decision making like terrain, time of day (i.e. day / night), special abilities, enemy units’ status etc.

Positioning is a crucial part, ideally we should try to position every unit such that it has backup from other units and is away from critical danger, also positioning in terrain that would support maximum defense if ideal. Next we must try to exploit the enemies weakness, e.g. if the enemies unit has no defense in range, then we should attack that unit with heavy range units. Also while attacking we must try to surround the enemy from multiple directions and then synchronize the attack.

For implementation I propose use different parameters like aggression, depth etc. Here aggression parameter would specify how much the AI values its own units as opposed to that of the enemies. Depth parameter indicates the number of units that will attack a single opponent unit. protect_leader (radius) parameter, it is used to target any enemy unit which comes within the specified radius around the leader, and many others will be needed.

The value of aggression will determine whether to play offensively or to retreat. Next I propose the use of decision tree to determine the value of aggression. The decision tree will be a binary tree and in each node we check some condition like terrain, time of day etc. which affects our strategy. So we start from the root node and after validating all the conditions we end up on a leaf node. The value of aggression will be determined on the basis of the leaf node we end up on.

As mentioned earlier positioning is very important. Positioning of units is different for aggressive and defensive approaches. To plan out the positioning we will use threat map. A threat map is a 2D array which describes the level of danger on every position. While building a threat map, the positioning of the enemy units, type of units and other factors are taken into account.
