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
  • unsynced luarules now recieves all synced luarules callins (could break very lazily coded gadgets, also if game includes gadgethandler then it should be updated to match, 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)

Spring 96.0

Spring 95.0
