C# Class Box2D.Collision.Distance.DistanceProxy

A distance proxy is used by the GJK algorithm. It encapsulates any shape. TODO: see if we can just do assignments with m_vertices, instead of copying stuff over

Public Methods

Method	Description
DistanceProxy ( ) : System
GetSupport ( Vec2 d ) : int	Get the supporting vertex index in the given direction.
GetSupportVertex ( Vec2 d ) : Vec2	Get the supporting vertex in the given direction.
GetVertex ( int index ) : Vec2	Get a vertex by index. Used by Distance.
Set ( Shape shape, int index ) : void	Initialize the proxy using the given shape. The shape must remain in scope while the proxy is in use.
