Public Methods

Method	Description
World ( Vector2 gravity ) : System	Initializes a new instance of the World class.
addBreakableBody ( BreakableBody breakableBody ) : void
addController ( Controller controller ) : void
addJoint ( Joint joint ) : void	Create a joint to constrain bodies together. This may cause the connected bodies to cease colliding.
clear ( ) : void
clearForces ( ) : void	Call this after you are done with time steps to clear the forces. You normally call this after each call to Step, unless you are performing sub-steps. By default, forces will be automatically cleared, so you don't need to call this function.
overlapCircle ( Vector2 center, float radius ) : void
processAddedBodies ( ) : void
processAddedJoints ( ) : void
processChanges ( ) : void	All adds and removes are cached by the World duing a World step. To process the changes before the world updates again, call this method.
processRemovedBodies ( ) : void
processRemovedJoints ( ) : void
queryAABB ( AABB &aabb ) : List	Query the world for all fixtures that potentially overlap the provided AABB. Use the overload with a callback for filtering and better performance.
queryAABB ( bool>.Func callback, AABB &aabb ) : void	Query the world for all fixtures that potentially overlap the provided AABB. Inside the callback: Return true: Continues the query Return false: Terminate the query
rayCast ( Vector2 point1, Vector2 point2 ) : List
rayCast ( Func callback, Vector2 point1, Vector2 point2 ) : void	Ray-cast the world for all fixtures in the path of the ray. Your callback controls whether you get the closest point, any point, or n-points. The ray-cast ignores shapes that contain the starting point. Inside the callback: return -1: ignore this fixture and continue return 0: terminate the ray cast return fraction: clip the ray to this point return 1: don't clip the ray and continue
removeBody ( Body body ) : void	Destroy a rigid body. Warning: This automatically deletes all associated shapes and joints.
removeBreakableBody ( BreakableBody breakableBody ) : void
removeController ( Controller controller ) : void
removeJoint ( Joint joint ) : void	Destroy a joint. This may cause the connected bodies to begin colliding.
removeJoint ( Joint joint, bool doCheck ) : void
shiftOrigin ( Vector2 newOrigin ) : void
solve ( TimeStep &timeStep ) : void
step ( float dt ) : void	Take a time step. This performs collision detection, integration, and consraint solution.
testPoint ( Vector2 point ) : Fixture
testPointAll ( Vector2 point ) : List	Returns a list of fixtures that are at the specified point.
