The primary use of this data is to display animated objects in the environment (cars, helis, fans etc.). "Physics" may also work but the implementation is buggy and incomplete, you may be able to add a object that can be pushed around but if you try to jump on it you fall.


Position, rotation and scale are used only when the object is not animated, otherwise the origin matrix is used instead.


Objects are not automatically created when a level is loaded, they need to be created from script using the obj_create command. After that they can be controlled with other commands like obj_show, obj_hide, obj_kill, env_anim and env_setanim. In some cases the object geometry has been baked into the environment and needs to be hidden (by using "env_show objectScriptID 0") before playing an animation.
