C# Class Project290.Physics.Collision.Shapes.Shape

A shape is used for collision detection. You can create a shape however you like. Shapes used for simulation in World are created automatically when a Fixture is created. Shapes may encapsulate a one or more child shapes.

Public Methods

Method	Description
Clone ( ) : Shape	Clone the concrete 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.
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.

Method Details

Clone() public abstract method

Clone the concrete shape

public abstract Clone ( ) : Shape
return	Shape

ComputeAABB() public abstract method

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

public abstract 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 abstract 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 abstract ComputeProperties ( ) : void
return	void

RayCast() public abstract method

Cast a ray against a child shape.

public abstract 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

Shape() protected method
