Function Documentation

b2Distance()

B2_API void b2Distance	(	b2DistanceOutput *	output,
		b2SimplexCache *	cache,
		const b2DistanceInput *	input
	)

Compute the closest points between two shapes. Supports any combination of: b2CircleShape, b2PolygonShape, b2EdgeShape. The simplex cache is input/output. On the first call set b2SimplexCache.count to zero.

Definition at line 454 of file b2_distance.cpp.

b2ShapeCast()

B2_API bool b2ShapeCast	(	b2ShapeCastOutput *	output,
		const b2ShapeCastInput *	input
	)

Perform a linear shape cast of shape B moving and shape A fixed. Determines the hit point, normal, and translation fraction.

Returns

true if hit, false if there is no hit or an initial overlap
