About this page

This page holds informations about engine changes that are relevant to game/map makers. The idea is to replace the "make your game ready for next release"-threads with a wiki page because unlike a forumpost, everybody can edit this. So if you find a thread (or mantis post etc) that explains a fix, please add it here. Back-link to forum. Use for bumping.

Spring 98.0

slight changes:

• fix definitions of UnitDef::Is{Strafing,Hovering}AirUnit b95764cd
• experience has slightly different effects: 0f59e103 , http://springrts.com/mantis/view.php?id=4446
• synced/unsynced now have the same callins (could break very lazily coded gadgets, also gadgethandler must be updated or unsynced luarules chatactions will be executed twice)
• each usage of SYNCED now makes a copy of the whole table
• types of variables returned from callins are now checked, e.g. MouseMove must return a bool
• TTL for LightningCannon now needs to be set in weapondefs, as 'beamttl' (see https://github.com/spring/spring/commit/dd7d1f79c3a9b579f874c210eb4c2a8ae7b72a16)
• Spring.GetUnitCommands/Spring.UnitCommandQueue won't work if they are called to often without a limit on the size of the table they return. Use e.g. Spring.GetUnitCommands(unitID, maxQueueSize)
