For someone who doesn't know the map like the back of their hand it may be very difficult to spot exactly what changed. There isn't any really good way to do this right now -- using the 'diff' tool at command line doesn't give good results for .map files. </p><p>Such a tool would be helpful for someone who maintains a map pool containing maps made by others, also for someone who wants to browse a repository and examine balance changes on several maps, which could be instructive for someone who wants to make and balance their own maps. </p><p>There's any number of ways to actually do this, one might be to have a feature in the map editor that takes the name of another map and adds map labels to indicate what hexes changed. It could also be a command accessible in debug mode when playing the game, or it could be an additional command-line argument (--diff [map1] [map2] ?) for the game. (It could be a standalone application but that's probably going to end up with much more work for you.) </p><p><a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/2323">https://github.com/wesnoth/wesnoth/issues/2323</a> </p><p>Note that the current status here is that a "map diff" tool now actually exists as a GitHub action that runs on pull requests with changed maps, although there are some bugs with it that could be fixed, and having a native "map diff" tool that runs as part of Wesnoth itself would fit the original request better. </p> <h3><span class="mw-headline" id="Add_an_option_to_not_store_replays">Add an option to not store replays</span></h3> <p>As noted in <a rel="nofollow" class="external free" href="https://wiki.wesnoth.org/SavefileWML">https://wiki.wesnoth.org/SavefileWML</a> all normal savefiles usually contain [replay] and [replay_start] tags that usually take over 50% of the total savefile size and are only used for providing the possibility to replay scenarios. It's be nice to have an option to skip these information to reduce the savefile size. Alternatively one could create a tool integrated in a load/savegame dialog to remove the replay information from a given savegame file. </p><p>See the feature request <a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/1457">https://github.com/wesnoth/wesnoth/issues/1457</a> </p> <h2><span class="mw-headline" id="MP_related_features">MP related features</span></h2> <h3><span class="mw-headline" id="Add_possibility_to_switch_off_mod_dependency_checking">Add possibility to switch off mod dependency checking</span></h3> <p>MP modifications 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). </p><p><a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/2324">https://github.com/wesnoth/wesnoth/issues/2324</a> </p> <h3><span class="mw-headline" id="Make_a_header_for_the_add-on_when_we_organize_scenarios_by_add-on_in_the_MP_create_dialog">Make a header for the add-on when we organize scenarios by add-on in the MP create dialog</span></h3> <p>Using an established GUI technique to signal when one block of scenarios for an add-on ends and the next begins would make it much easier to use this dialog, if the user has several add-ons. </p><p>See one proposal here: <a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/1365">https://github.com/wesnoth/wesnoth/issues/1365</a> </p> <h3><span class="mw-headline" id="Timer_pause_button">Timer pause button</span></h3> <p>Longstanding feature request here: <a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/1237">https://github.com/wesnoth/wesnoth/issues/1237</a> </p><p>Request is for either a button, or a simple chat command like :pause, :unpause, to allow players to put the timer on hold if they are interrupted. </p><p>Ideally would be accompanied with a multiplayer-only scenario attribute "number_of_pauses" which decreases each time a client pauses the game. Pause should use a blindfold object to black out the screen, and send a chat message automatically when it occurs / resume occurs. For an example of how it might look, start a local hotseat mp game and enable the Preferences->General->Turn Dialog option. (This behavior was introduced in this commit: <a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/commit/bab03d554bea92f1ce6f585ef1123202173a3491">https://github.com/wesnoth/wesnoth/commit/bab03d554bea92f1ce6f585ef1123202173a3491</a>) </p><p>Wintermute/happygrue also has other ideas about how the timer should/could work. For example, instead of their client ending their turn, the networked opponents could be required to "confirm" the time out. (This is probably a networked MP-only idea.) </p><p>A very fancy implementation might instead of a counter, allow the other players to vote on whether a pause request is granted. </p><p>Make sure that the paused client still responds to network commands, so that it is possible to kick a person who pauses and then doesn't ever unpause. </p> <h3><span id="Add_a_"concede"_button"></span><span class="mw-headline" id="Add_a_.22concede.22_button">Add a "concede" button</span></h3> <p>Often times in mp, players concede the game before their leader is actually killed. When the game ends 'officially' the map is revealed, which can sometimes be instructive for the losing player. Additionally, it makes it easier to analyze the results of many games, for purposes of balancing, or for maintaining a ladder. So while it may seem small, this would actually be a pretty useful feature. </p><p>There was a PR to fix this, but it never got merged due to being broken: <a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/pull/535">https://github.com/wesnoth/wesnoth/pull/535</a> </p><p>This could be implemented in lua. </p> <h3><span id="Show_[options]_values_in_the_mp_lobby_gameslist"></span><span class="mw-headline" id="Show_.5Boptions.5D_values_in_the_mp_lobby_gameslist">Show [options] values in the mp lobby gameslist</span></h3> <p>It'd be useful for a newly-joining player to see the chosen [options] of a mp game, since most likely there isn't enough space we could for example wigher show the options via an extra dropdown button in the lobby or show them in the mp waiting dialog instead. </p><p>See the featurerequest <a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/1514">https://github.com/wesnoth/wesnoth/issues/1514</a> </p> <h2><span class="mw-headline" id="WML-related_features">WML-related features</span></h2> <h3><span class="mw-headline" id="Support_variable_poison_properties">Support variable poison properties</span></h3> <p>See a feature request here: </p><p><a rel="nofollow" class="external free" href="https://github.com/wesnoth/wesnoth/issues/1339">https://github.com/wesnoth/wesnoth/issues/1339</a> </p> <h3><span class="mw-headline" id="Events_Manipulation">Events Manipulation</span></h3> <ul><li>[event] persistent="yes" - creates an event that lasts for the rest of the campaign</li> <li>[disable_event][/disable_event] disables the event within which it appears (useful with conditionals).
