C# Класс Box2D.Dynamics.Fixture

A fixture is used to attach a shape to a body for collision detection. A fixture inherits its transform from its parent. Fixtures hold additional non-geometric data such as friction, collision filters, etc. Fixtures are created via Body::CreateFixture.

Открытые методы

Метод	Описание
Create ( Body body, FixtureDef def ) : void
CreateProxies ( BroadPhase broadPhase, Transform xf ) : void
Destroy ( ) : void
DestroyProxies ( BroadPhase broadPhase ) : void	Internal method
Dump ( int bodyIndex ) : void	Dump this fixture to the log file.
Fixture ( ) : System
GetAABB ( int childIndex ) : AABB	Get the fixture's AABB. This AABB may be enlarge and/or stale. If you need a more accurate AABB, compute it using the shape and the body transform.
GetMassData ( MassData massData ) : void	Get the mass data for this fixture. The mass data is based on the density and the shape. The rotational inertia is about the shape's origin.
Raycast ( RayCastOutput output, RayCastInput input, int childIndex ) : bool	Cast a ray against this shape.
Refilter ( ) : void	Call this if you want to establish collision that was previously disabled by ContactFilter::ShouldCollide.
TestPoint ( Vec2 p ) : bool	Test a point for containment in this fixture. This only works for convex shapes.
