Changeset 5929 for code/trunk/src/libraries/core/Game.cc

Timestamp:

Oct 12, 2009, 8:20:07 PM (16 years ago)

Author:

Message:

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
