C# Class FarseerPhysics.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.

Méthodes publiques

Méthode	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.
ComputeMass ( MassData &massData, float density ) : 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.

public abstract ComputeMass ( MassData &massData, float density ) : void
massData	MassData	Returns the mass data for this shape.
density	float	The density in kilograms per meter squared.
Résultat	void

RayCast() public abstract méthode

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.
