Game Data is used to hold Data which is needed to drive the game

set default settings

Load the current game State from a typical quake3 cfg file

-

s32 GameData::load ( const path &filename )
-{

-        return 0;
-
-    // the quake3 mesh loader can also handle *.shader and *.cfg file

Store the current game State in a quake3 configuration file

so we need a good starting Position in the level. we can ask the Quake3 Loader for all entities with class_name "info_player_deathmatch"

set the Animation of the player and weapon
