Question by Gabriel-Oliveira-Almeida · Mar 15, 2016 at 01:47 PM · c#collision detectiontesting

Collision working once

Hi guys! I testing some collision, and i have a problem. I make this scenario: ![alt text][1]

The idea is, addforce by rigidbody, in the ball, he go ups, bounce wall, go down, bounce platformer, go up again and stays in this forever.

Every time the ball collide with something, in the console print "hit". The Script:

 float speed = 10f;
 // Use this for initialization
 void Start () {
     GetComponent<Rigidbody> ().velocity = Vector3.up * speed;
 }

 void OnCollisionExit (Collision Col)
 {
     if (Col.gameObject.tag != "Respawn") {
         Debug.Log ("hit");
     }

 }

The Problem is.....in the console only appears hit, in the first colission, all other they dont work. Why this happens? What i make wrong?

I found the issue, is the Unity itself. I update for the last version, and the script works. Thx for the help.

Perhaps you need to run it through FixedUpdate or somehow make it repeat the script constantly.

You could also try OnCollisionEnter, and see if that calls the script every time it bounces.

I tryin put in Update and FixedUpdate, but dont work. I thiking this function call its self, when have a colision. I trying Change to CollisionEnter, but have the same effect, only print one hit. The ball bounce like 5 times in the top wall and the raket, but print only one time.

On your Rigidbody, make the Collison Detection Continuous.
