source: code/branches/presentation2/data/lua/LuaStateInit.lua @ 6404

Last change on this file since 6404 was 6404, checked in by rgrieder, 14 years ago

Simplified our resource system a bit by working with a single resource group on the user end.
However you can still declare resource groups for separate loading. But accessing the files will always look in all groups.
