The state of this world's physics space. This allows arbitrary querying for collision.
Direct access to the world's physics 2D space state. Used for querying current and potential collisions. Must only be accessed from the main thread within [code]_physics_process(delta)[/code].
The World3D's physics direct space state, used for making various queries. Might be used only during [code]_physics_process[/code].
