C# Класс FarseerPhysics.Dynamics.Contacts.Contact

The public 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.

Описание свойств

enabled публичное свойство

Enable/disable this contact. This can be used inside the pre-solve contact listener. The contact is only disabled for the current time step (or sub-step in continuous collisions). NOTE: If you are setting Enabled to a constant true or false, use the explicit Enable() or Disable() functions instead to save the CPU from doing a branch operation.

public bool enabled
Результат	bool

fixtureA публичное свойство

public Fixture fixtureA
Результат	Fixture

fixtureB публичное свойство

public Fixture fixtureB
Результат	Fixture

friction публичное свойство

public float friction
Результат	float

manifold публичное свойство

Get the contact manifold. Do not modify the manifold unless you understand the internals of Box2D.

public Manifold,FarseerPhysics.Collision manifold
Результат	FarseerPhysics.Collision.Manifold

restitution публичное свойство

public float restitution
Результат	float

tangentSpeed публичное свойство

public float tangentSpeed
Результат	float
