Changeset 2023 for code/branches/objecthierarchy/src

Timestamp:

Oct 27, 2008, 10:56:51 PM (16 years ago)

Author:

Message:

• Added support for dedicated server. Could not network test it yet, client still segfaults me.
• Also kicked GraphicsEngine::levelSceneManager_, there are only the statistic methods left.
• GSDedicated also derives from GSLevel, but GSLevel is not anymore a real GameState.
• CameraHandler and LevelManager get created in GSLevel now.
