C# Class FarseerPhysics.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. Warning: You cannot reuse fixtures.

Public Methods

Method	Description
GetAABB ( AABB &aabb, int childIndex ) : void	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.
IgnoreCollisionWith ( Fixture fixture ) : void	Ignores collisions between this fixture and the provided fixture.
IsFixtureIgnored ( Fixture fixture ) : bool	Determines whether collisions are ignored between this fixture and the provided fixture.
RayCast ( RayCastOutput &output, RayCastInput &input, int childIndex ) : bool	Cast a ray against this Shape.
RestoreCollisionWith ( Fixture fixture ) : void	Restores collisions between this fixture and the provided fixture.
TestPoint ( System.Vector2 &point ) : bool	Test a point for containment in this fixture.

Method Details

GetAABB() public method

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.

public GetAABB ( AABB &aabb, int childIndex ) : void
aabb	FarseerPhysics.Collision.AABB	The aabb.
childIndex	int	Index of the child.
return	void

GetMassData() public method

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.

public GetMassData ( MassData &massData ) : void
massData	FarseerPhysics.Collision.Shapes.MassData	The mass data.
return	void

IgnoreCollisionWith() public method

Ignores collisions between this fixture and the provided fixture.

public IgnoreCollisionWith ( Fixture fixture ) : void
fixture	Fixture	The fixture.
return	void

IsFixtureIgnored() public method

Determines whether collisions are ignored between this fixture and the provided fixture.

public IsFixtureIgnored ( Fixture fixture ) : bool
fixture	Fixture	The fixture.
return	bool

RayCast() public method

Cast a ray against this Shape.

public RayCast ( RayCastOutput &output, RayCastInput &input, int childIndex ) : bool
output	FarseerPhysics.Collision.RayCastOutput	The ray-cast results.
input	FarseerPhysics.Collision.RayCastInput	The ray-cast input parameters.
childIndex	int	Index of the child.
return	bool

RestoreCollisionWith() public method

Restores collisions between this fixture and the provided fixture.

public RestoreCollisionWith ( Fixture fixture ) : void
fixture	Fixture	The fixture.
return	void

TestPoint() public method

Test a point for containment in this fixture.

public TestPoint ( System.Vector2 &point ) : bool
point	System.Vector2	A point in world coordinates.
return	bool

Property Details

OnCollision public_oe property

Fires when two shapes collide and a contact is created between them. Note that the first fixture argument is always the fixture that the delegate is subscribed to.

public CollisionEventHandler OnCollision
return	CollisionEventHandler

OnSeparation public_oe property

Fires when two shapes separate and a contact is removed between them. Note that the first fixture argument is always the fixture that the delegate is subscribed to.

public SeparationEventHandler OnSeparation
return	SeparationEventHandler

PostSolve public_oe property

public Action PostSolve
return	Action

Proxies public_oe property

public FixtureProxy[],FarseerPhysics.Dynamics Proxies
return	FarseerPhysics.Dynamics.FixtureProxy[]

ProxyCount public_oe property

public int ProxyCount
return	int
