Problem with OnTriggerEnter... No solution found on internet works

Unity Engine
1

yes, i know that the GameObject must have a rigidboyd attached to it. I’ve rigidbody and capsule collider attached to the object (called powerCell) in which i’ve attached this script too

void OnTriggerEnter(Collider col){
		Debug.Log ("pick");
		if(col.gameObject.tag == "Player"){

			col.gameObject.SendMessage("CellPickup");
			Destroy(gameObject);
		}
	}

But when i launch the game, once the player reach the powerCell no event is trigger. Why ??
Also noted that If in capsule collider inspector i check “is trigger”, i correctly see “pick” into the console, so the event is correctly launched :o

Probably you are a little confused.

void OnTriggerEnter(Collider col)

will work only if the collider attached to the object that your script is attached too is set as trigger.

If you don’t want the collider to be a trigger you need to use

void OnCollisionEnter(Collision col)

they are 2 different callbacks that will react in 2 different ways.

The book Unity 3.x Development Essentials (even if I am using the 4.3 build), page 192 uses OnTriggerEnter…
I tryed OnCollisionEnter too but the problem is the same

EDIT: ahh ok solved… i thought that is trigger had been an option to trigger the event at launch…
