MonoBehaviour.OnCollisionExit(Collision)

Parameters

Description

OnCollisionExit is called when this collider/rigidbody has stopped touching another rigidbody/collider.

In contrast to OnTriggerExit, OnCollisionExit 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.

function OnCollisionExit(collisionInfo : Collision) {
    print("No longer in contact with " + collisionInfo.transform.name);
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void OnCollisionExit(Collision collisionInfo) {
        print("No longer in contact with " + collisionInfo.transform.name);
    }
}

OnCollisionExit can be a co-routine, simply use the yield statement in the function.
