OnCollisionEnter but have colliding object not move the object it collides with

Questions & Answers

Is it possible to use OnCollisionEnter or detect collision otherwise without having one object affect the position of the other?

i.e., bullet A hits Object B, but Object B does not move, bullet A goes “right through”

OnTriggerEnter with isTrigger checkboxed for the bullet and rigidbody set for both objects:

Vector3 v = new Vector3(0,0,-3);

public GUIText t;

// Use this for initialization
void Start () {

}


// Update is called once per frame
void Update () {
	transform.Translate(v);
}


void OnTriggerEnter(Collider col){

	t.text = col.gameObject.name;
	
}

you can set for the GameObjects that are Colliding in the Collider component settings in the inspector “is Trigger = true”
and call OnTriggerEnter instead of OnCollisionEnter … so the colliders will “fly” or go through each other.

so this way Bullet A hits Object B, and Object B does not Move, Bullet A goes through :slight_smile:

also, try to debug yor collition/trigger

void OnTriggerEnter(Collider col){
   Debug.Log("Collision True");
   t.text = col.gameObject.name;
    }
