메소드	설명
AddController ( Controllers def ) : Controller
CreateBody ( BodyDef def ) : Body	Create a rigid body given a definition. No reference to the definition is retained. @warning This function is locked during callbacks.
CreateJoint ( JointDef def ) : Joint	Create a joint to constrain bodies together. No reference to the definition is retained. This may cause the connected bodies to cease colliding. @warning This function is locked during callbacks.
DestroyBody ( Body b ) : void	Destroy a rigid body given a definition. No reference to the definition is retained. This function is locked during callbacks. @warning This automatically deletes all associated shapes and joints. @warning This function is locked during callbacks.
DestroyJoint ( Joint j ) : void	Destroy a joint. This may cause the connected bodies to begin colliding. @warning This function is locked during callbacks.
Dispose ( ) : void	Destruct the world. All physics entities are destroyed.
GetBodyCount ( ) : int	Get the number of bodies.

GetContactCount ( ) : int	Get the number of contacts (each may have 0 or more contact points).

SetContinuousPhysics ( bool flag ) : void	Enable/disable continuous physics. For testing.
SetDebugDraw ( DebugDraw debugDraw ) : void	Register a routine for debug drawing. The debug draw functions are called inside the World.Step method, so make sure your renderer is ready to consume draw commands when you call Step().
