EasyCoding

Foreword

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....)

--Boucman 20:48, 3 October 2006 (CEST)

Since bugs are sometimes a good opportunity to get a first idea of the code, i will add some here that are easy to fix as soon as i stumble upon them (the one i had in mind is fixed already ;-).

MP related features

Use different font for in-game chat

Since commas and dots are apparently hard to tell apart. As per FR #7470 [1]

WML related features

WML configurable village income / upkeep

Preferably as a [scenario], [side] or [campaign] keys. As per FR #6301 [2]. Patch submitted: [3] (gabba)

Add support of [if] for [scenario]

As per FR #4539 [4]

Make [have_unit] optionaly use full SUF

[have_unit] by default uses SUF but does not apply it to recall list. Introduce an optional key that will allow to lift that limitation.

Side-specific results

Giving result=defeat or result=victory for specific sides. (FR #4960) -- dlr365 -- patch submitted [5]

Support for leaderless multiplayergames

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

Support for standalone multiplayer scenarios

There used to be support for standalone scenarios in the userdata tree, in reorganising the trees this feature got lost and an add-on is now required to add a scenario. Re-add this feature. It is probably a good idea to mirror the mainline multiplayer tree.

Other Ideas

See FutureWML; some ideas there are easier than others.

Improvements to FormulaAI

Add new formula functions, or minor improvements to the formula language. Make it easier to debug the formula language.

Please discuss these with Dragonking, Sirp or Boucman

Use AI_Arena for testing custom formulas.

Poisoning Improvement

Writing a formula that will make units with poison attacks prioritize their targets to spead poison as much as possible, avoiding already poisoned units and other useless targets

About to level formula

Writing a formula that would handle units with only a few XP left to level and have them fight accordingly (most likely to kill or hit depending on XP needed, taking into account target's level)

Healer improvements

Handle units with healing power, moving them at places where they can provide the most healing

Leader improvements

A bit more complicated : special handling of units with leadership to have them support units. Only do it if it actually is usefull (less hits needed to kill the unit) and ability to help multiple units in a single turn (assuming enough MP)

Berserker improvements

The default AI's strategy of attacking as much as possible is very bad with berserker... A simple AI that would prevent the berserker from attacking (and keeping him close to fight without being exposed) and attack when the chance to kill is high enough would be an interesting addition

Debugging help

* provide a way for a formula to have a text float over hex (for debugging purpose). done by Crab, patch submitted [6]

• in debug mode, have all AI move print their name in the log

New type of candidate moves : Global

to be called only once with no implicit variable

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

• allow custom themes to display values of WML variables (FR #6209)
• hide the hourglass item from the statusbar when there is no timer

Widget Changes

• show side number, name and team association information in the status table
• make games sortable in the lobby (open slots, total number of players, era, XP modifier, gold per village, fog/shroud)
• input history (chat, commands, ..) - note: rujasu is working on this feature

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.

* Savegame dialog

This is a new dialog to write and requires the minimap code to be fixed first. The dialog should mimic the current dialog. Sorting of a listbox and the proper alignment of the columns is not important (the engine doesn't support this yet). The code should only be used when --new-widgets is used as start switch since we're in a feature freeze at the moment.

Arrow keys for the slider

There's a new slider widget, but it doesn't support the keyboard yet. gui/widgets/slider.[c|h]pp

Clicking on the widget should capture the keyboard and then arrow left/right should move one step even if not all steps are visible.

Slider sizing

There are some issues with the sizing of a slider. gui/widgets/slider.[c|h]pp

In a layout step it needs to try to shrink itself, not entirely sure where or how yet, best ask mordante on irc.

Savegame related stuff

consistent player information

At the moment, the [player]-section for a campaign savegame will appear in two places: The root level of the savegame and the [replay_start]-section. This was due to a last-minute fix for 1.6 that was designed to be the least intrusive. The [player]-section should only be written to [replay_start] (and of course read from there as well). Patch submitted: [7] -grantwu

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)
