Detailed Description

A distance proxy is used by the GJK algorithm. It encapsulates any shape.

Member Function Documentation

Set() [1/2]

void b2DistanceProxy::Set	(	const b2Shape *	shape,
		int32	index
	)

Initialize the proxy using the given shape. The shape must remain in scope while the proxy is in use.

Set() [2/2]

void b2DistanceProxy::Set	(	const b2Vec2 *	vertices,
		int32	count,
		float	radius
	)

Initialize the proxy using a vertex cloud and radius. The vertices must remain in scope while the proxy is in use.
