source: code/branches/menuanimations/src/orxonox/Level.cc @ 6921

Last change on this file since 6921 was 5929, checked in by rgrieder, 15 years ago

Merged core5 branch back to the trunk.
Key features include clean level unloading and an extended XML event system.

Two important notes:
Delete your keybindings.ini files! * or you will still get parser errors when loading the key bindings.
Delete build_dir/lib/modules/libgamestates.module! * or orxonox won't start.
Best thing to do is to delete the build folder ;)
