Unity3d OnCollisionEnter not firing

Questions & Answers

I made a simple script to detect collisions, but it doesn’t appear to be working. The collision doesn’t seem to be acknowledged whatsoever.

using UnityEngine;
    using System.Collections;    
    public class Pickup : MonoBehaviour {
    	// Update is called once per frame
    	void onCollisionEnterEnter (Collision col){
    		if(col.transform.tag.Contains("Weapon")){
    			Debug.Log ("Poke");
    		}
    	}
    }

Both the objects have colliders and rigidbodies. I cant seem to figure out why this isnt working. onTriggerEnter doesnt work either, even if one of the objects is set to be a trigger.

Your on collision enter function isnt capitalized replace onCollisionEnter with OnCollisionEnter
