Collider.OnCollisionStay(Collision)

参数

描述

OnCollisionStay is called once per frame for every Collider or Rigidbody that touches another Collider or Rigidbody.

In contrast to OnTriggerStay, OnCollisionStay is passed the Collision class and not a Collider. The Collision class contains information about contact points, impact velocity etc. If you don't use collisionInfo in the function, leave out the collisionInfo parameter as this avoids unneccessary calculations. Notes: Collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached. Collision events are sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions. Collision stay events are not sent for sleeping Rigidbodies.

public class Example : MonoBehaviour
{
    void OnCollisionStay(Collision collisionInfo)
    {
        // Debug-draw all contact points and normals
        foreach (ContactPoint contact in collisionInfo.contacts)
        {
            Debug.DrawRay(contact.point, contact.normal * 10, Color.white);
        }
    }
}
