 			Sets which physics engine to use for 2D physics.
 			"DEFAULT" and "GodotPhysics2D" are the same, as there is currently no alternative 2D physics server implemented.
+			"Dummy" is a 2D physics server that does nothing and returns only dummy values, effectively disabling all 2D physics functionality.

 			If [code]true[/code], the 2D physics server runs on a separate thread, making better use of multi-core CPUs. If [code]false[/code], the 2D physics server runs on the main thread. Running the physics server on a separate thread can increase performance, but restricts API access to only physics process.
