Rigidbody.OnCollisionStay(Collision)

Description

OnCollisionStay вызывается один раз в кадр для каждого collider/rigidbody, который касается другого rigidbody/collider.

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 will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions. Collision stay events are not sent for sleeping Rigidbodies.

// Debug-draw all contact points and normals

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void OnCollisionStay(Collision collisionInfo)
    {
        foreach (ContactPoint contact in collisionInfo.contacts)
        {
            Debug.DrawRay(contact.point, contact.normal, Color.white);
        }
    }
}
