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.

Clone() public method

public Clone ( ) : Shape
return	Shape

ComputeAABB() public method

Given a transform, compute the associated axis aligned bounding box for a child shape.

public ComputeAABB ( AABB &aabb, Transform &transform, int childIndex ) : void
aabb	AABB	The aabb results.
transform	Transform	The world transform of the shape.
childIndex	int	The child shape index.
return	void

ComputeProperties() public method

Compute the mass properties of this shape using its dimensions and density. The inertia tensor is computed about the local origin, not the centroid.

public ComputeProperties ( ) : void
return	void

EdgeShape() public method

public EdgeShape ( Vector2 start, Vector2 end ) : Microsoft.Xna.Framework
start	Microsoft.Xna.Framework.Vector2
end	Microsoft.Xna.Framework.Vector2
return	Microsoft.Xna.Framework

RayCast() public method

Cast a ray against a child shape.

public RayCast ( RayCastOutput &output, RayCastInput &input, Transform &transform, int childIndex ) : bool
output	RayCastOutput	The ray-cast results.
input	RayCastInput	The ray-cast input parameters.
transform	Transform	The transform to be applied to the shape.
childIndex	int	The child shape index.
return	bool

Set() public method

Set this as an isolated edge.

public Set ( Vector2 start, Vector2 end ) : void
start	Microsoft.Xna.Framework.Vector2	The start.
end	Microsoft.Xna.Framework.Vector2	The end.
return	void

TestPoint() public method

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

public TestPoint ( Transform &transform, Vector2 &point ) : bool
transform	Transform	The shape world transform.
point	Microsoft.Xna.Framework.Vector2	a point in world coordinates.
return	bool
