C# 클래스 Box2D.Collision.Broadphase.BroadPhase

The broad-phase is used for computing pairs and performing volume queries and ray casts. This broad-phase does not persist pairs. Instead, this reports potentially new pairs. It is up to the client to consume the new pairs and to track subsequent overlap.

공개 메소드들

메소드	설명
BroadPhase ( ) : System
CreateProxy ( AABB aabb, object userData ) : int	Create a proxy with an initial AABB. Pairs are not reported until updatePairs is called.
DestroyProxy ( int proxyId ) : void	Destroy a proxy. It is up to the client to remove any pairs.
DrawTree ( DebugDraw argDraw ) : void
GetFatAABB ( int proxyId ) : AABB
GetUserData ( int proxyId ) : object
MoveProxy ( int proxyId, AABB aabb, Vec2 displacement ) : void	Call MoveProxy as many times as you like, then when you are done call UpdatePairs to finalized the proxy pairs (for your time step).
Query ( ITreeCallback callback, AABB aabb ) : void	Query an AABB for overlapping proxies. The callback class is called for each proxy that overlaps the supplied AABB.
Raycast ( ITreeRayCastCallback callback, RayCastInput input ) : void	Ray-cast against the proxies in the tree. This relies on the callback to perform a exact ray-cast in the case were the proxy contains a shape. The callback also performs the any collision filtering. This has performance roughly equal to k * log(n), where k is the number of collisions and n is the number of proxies in the tree.
TestOverlap ( int proxyIdA, int proxyIdB ) : bool
TouchProxy ( int proxyId ) : void
TreeCallback ( int proxyId ) : bool	This is called from DynamicTree::query when we are gathering pairs.
UpdatePairs ( IPairCallback callback ) : void	Update the pairs. This results in pair callbacks. This can only add pairs.
