Public Methods

Method Description
Clone ( ) : Shape
ComputeAABB ( AABB &aabb, Transform &transform, int childIndex ) : void

Given a transform, compute the associated axis aligned bounding box for a child shape.
ComputeProperties ( ) : void

Compute the mass properties of this shape using its dimensions and density. The inertia tensor is computed about the local origin, not the centroid.
EdgeShape ( Vector2 start, Vector2 end ) : Microsoft.Xna.Framework
RayCast ( RayCastOutput &output, RayCastInput &input, Transform &transform, int childIndex ) : bool

Cast a ray against a child shape.
Set ( Vector2 start, Vector2 end ) : void

Set this as an isolated edge.
TestPoint ( Transform &transform, Vector2 &point ) : bool

Test a point for containment in this shape. This only works for convex shapes.
