Collision 碰撞

# Collision 碰撞

Describes collision.

描述碰撞。

Collision information is passed to [Collider.OnCollisionEnter](../Collider/Collider.OnCollisionEnter.html),
[Collider.OnCollisionStay](../Collider/Collider.OnCollisionStay.html)
and [Collider.OnCollisionExit](../Collider/Collider.OnCollisionExit.html)
events.

碰撞（Collision）信息是传递到 [Collider.OnCollisionEnter](../Collider/Collider.OnCollisionEnter.html)，
[Collider.OnCollisionStay](../Collider/Collider.OnCollisionStay.html)
和 [Collider.OnCollisionExit](../Collider/Collider.OnCollisionExit.html) 事件。

参见: [ContactPoint](../ContactPoint/ContactPoint.html).

### Variables**变量**

* [relativeVelocity](Collision.relativeVelocity.html)
  The relative linear velocity of the two colling objects
  (Read Only).
  两个碰撞物体的相对线性速度（只读）。
* [rigidbody](Collision.rigidbody.html)
  The Rigidbody we hit (Read Only). This is null if the
  object we hit is a collider with no rigidbody
  attached.

  The Collider we hit (Read Only).
  我们碰撞的碰撞器（只读）。
* [transform](Collision.transform.html)
  The Transform of the object we hit (Read
  Only).
  我们碰撞的物体的 [Transform](../Transform/Transform.html)（只读）。
* [gameObject](Collision.gameObject.html)
  /gameObject/ is the object we are colliding with. (Read
  Only).
  gameObject 是我们碰撞的物体（只读）。
* [contacts](Collision.contacts.html)
  The contact points generated by the physics
  engine.
  接触点由物理引擎产生。
