item (abstract tag)

Items are simple moveable objects and the parent tag of weapon, garbage, and equipment. Although they can have a hitbox in the form of a model_collision_geometry, when moving they are simulated as simple point-like objects that can bounce off the BSP and non-item objects. Unlike units, they cannot be controlled or die (though they can despawn).
