C# Class FarseerPhysics.Collision.Shapes.LoopShape

A loop Shape is a free form sequence of line segments that form a circular list. The loop may cross upon itself, but this is not recommended for smooth collision. The loop has double sided collision, so you can use inside and outside collision. Therefore, you may use any winding order.

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.
ComputeMass ( MassData &massData, float density ) : void	Chains have zero mass.
GetChildEdge ( EdgeShape &edge, int index ) : void	Get a child edge.
LoopShape ( ) : System.Diagnostics
RayCast ( RayCastOutput &output, RayCastInput &input, Transform &transform, int childIndex ) : bool	Cast a ray against a child shape.
TestPoint ( Transform &transform, Vector2 &point ) : bool	Test a point for containment in this shape. This only works for convex shapes.
