Class that has everything pertaining to a 2D world. A physics space, a visual scenario, a navigation map and a sound space. 2D nodes register their resources into the current 2D world.
Direct access to the world's physics 2D space state. Used for querying current and potential collisions. When using multi-threaded physics, access is limited to [code]_physics_process(delta)[/code] in the main thread.
The [RID] of this world's vertex light 2d space resource. Used by the [VertexLights2DServer] for static 2D lights. If the vertex lights 2d module is not enabled this will just return an empty RID.
