EasyCoding

Foreword

We are currently in the process of updating this page. Parts marked by ~~strikeout~~ will likely be deleted shortly.

This page is here to document easy to do coding tasks. It is not here to double the feature request database, and should only be filled by people that know the code well enough to judge the difficulty of a given task.

If you are such a person, you should feel free to edit this page.

If you're not, you should post a feature request and discuss your idea on the forum or IRC. A coder with better knowledge of the code might give you the green light to add your feature here.

Anybody should feel free to add "clues" to any tasks, that is entry points, traps to avoid, person to contact to discuss and so on.

If you plan to work on a feature, write your name at the bottom of the feature, with the date. Note that if you are too long at working on a feature I'll "free" it back (that is if you're not working on it. If you have problems implementing it, just tell us....)

MP related features

Add possibility to give reason for "ignore"

As per FR #16001 [1]

See https://github.com/wesnoth/wesnoth-old/pull/1

Add possibility to switch off dependency checking

MP add-ons can define dependencies. Currently there's no way to force a "broken" configuration, although overzealous use of the system by UMC authors could make this feature useful. Add an option to the MP game creation screen to switch on/off dependency checking. Ask lipk (forum)/lipkab (IRC).

WML related features

Side-specific results

Giving result=defeat or result=victory for specific sides. (FR #4960) -- dlr365 -- patch submitted [2]

--Boucman 08:58, 28 February 2010 (UTC) Patch seems abandonned, but can be used for further work feel free to take over the FR

Support for leaderless multiplayergames

Add support for the WML key victory_when_enemies_defeated= in the scenario tag during multiplayergames. (FR #8106)

Support variable recall cost in wml

see https://gna.org/bugs/?16538

the syntax needs to be discussed and refined, but the overall idea is good

make sure to update whiteboard to handle this correctly

Ask Boucman

Other Ideas

See FutureWML; some ideas there are easier than others.

Improvements to AI

Note: not all of these are simple tasks. Talk to Crab or mattsc.

Setting aspects in the [side] tag like this:

[ai]
    aggression=0.123
[/ai]

does not work if the Lua engine is defined. You either need to use the [aspect] tag in the [side] tag with 'engine=lua', or use the code above in a [modify_side] tag in an event. Making the above syntax available (as it is with the c++ engine) would be nice. The same also applies to the FAI engine and to aspects set for AI sides in MP games.

Set up an option the allows us to exclude units from the move-to-targets phase similar to [filter_own] for the combat phase (other than setting ai_special=guardian, which has a number of other side effects). Actually, having this option for all CA's would be nice. (This is not a simple task. Some first attempts to do it have been made, but work seems abandoned at the moment.)

Set up a capability for letting a custom AI choose what unit type a unit advances to at the time of leveling up. (flix will work on this - 17 April 2013, Patch submitted [3])

Currently, setting goto_x, goto_y makes the unit go to that location in a straight line, even if that leads into a dead end. It would be nice to have this changed so that the unit uses the shortest possible path instead. All the pieces for this are in place, should be pretty easy to do. (flix will work on this - 13 April 2013, Patch submitted [4])

A number of AI parameters (aspects) have been deprecated. Add deprecation messages for those. This also involves fixing the syntax of mainline campaigns that use deprecated parameters. (PL_kolek will work on this - 21 April 2013)

Add more replay-safe actions to the Lua AI actions. A first step could be to add an AI action (and add lua function to do that) to use a right-click menu item.

In standard MP game or campaign game, if side X (e.g X=1) is human, wesnoth.debug_ai(X) segfaults wesnoth since lua ai for side X is undefined. fix it (by making debug_ai initialize the standard lua ai for side X if it's not yet initialized) (flix will work on this - 26 April 2013, Patch submitted [5])

GUI related features

Note at the moment Mordante is working on a new GUI system, these changes will probably affect the way these items need to be implemented. Contact Mordante on IRC before starting to work on these.

--SkeletonCrew 14:04, 9 March 2008 (EDT)

Theme Changes

hide the hourglass item from the statusbar when there is no timer

Widget Changes

make games sortable in the lobby (open slots, total number of players, era, XP modifier, gold per village, fog/shroud)
input history (chat, commands, ..)

GUI2 related features

GUI2 is the new gui engine Mordante/SkeletonCrew is working on.

Information on the wiki can be found here http://www.wesnoth.org/wiki/GUIToolkit
The source code is under src/gui/
The configuration config files are under data/gui/default

Some tasks need the --new-widgets since the code is only shown in the experimental mode. Tasks which need this switch have the * in the title.

Port the random map generator dialog to GUI2

The map generator currently doesn't use the GUI2 framework, but there's no reason why it couldn't. Ask lipk (forum)/lipkab (IRC).

Miscellaneous

More powerful village naming

Adding mountain names and other features to village names, having a second random name in village names

Currently the village naming engine has a very good structure that could allow more powerfull names to be generated. Understanding how it works should be quite easy, and a few usefull improvements could be added.

Currently villages can use lake names and river names, this should be extended to other features like bridges, swamps, mountains etc...
It would be nice to have a separate list of "first sylabus" and "last sylabus" for naming. That's not really needed in english, but some translations could use it
Again, it is common to have villages with more than one "random" word in them. having a $name2 variable would be nice

Debug Mode

New debug command functionality (setting additional status.variables, possibly terrain)
Add a right-click option in debug mode to kill the unit under the cursor
