C# Class Project290.Physics.Dynamics.Contacts.Contact

The class manages contact between two shapes. A contact exists for each overlapping AABB in the broad-phase (except if filtered). Therefore a contact object may exist that has no contact points.

Public Methods

Method	Description
FlagForFiltering ( ) : void	Flag this contact for filtering. Filtering will occur the next time step.
GetManifold ( Manifold &manifold ) : void	Get the contact manifold. Do not modify the manifold unless you understand the internals of Box2D.
GetWorldManifold ( Vector2 &normal, FixedArray2 &points ) : void	Gets the world manifold.
IsTouching ( ) : bool	Determines whether this contact is touching.

Private Methods

Method	Description
Contact ( Fixture fA, int indexA, Fixture fB, int indexB ) : System
Create ( Fixture fixtureA, int indexA, Fixture fixtureB, int indexB ) : Contact
Destroy ( ) : void
Evaluate ( Manifold &manifold, Transform &transformA, Transform &transformB ) : void	Evaluate this contact with your own manifold and transforms.
Reset ( Fixture fA, int indexA, Fixture fB, int indexB ) : void
Update ( ContactManager contactManager ) : void	Update the contact manifold and touching status. Note: do not assume the fixture AABBs are overlapping or are valid.
