Help! OnTriggerCollider not working

Not sure what I’m doing wrong. One object has rigid body, one object has 2d collidor with a trigger. This script is attached to the object with the 2d collider with trigger:

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class KillerLogic : MonoBehaviour {

void OnTriggerEnter(Collider other)
	Debug.Log ("hit");

// Update is called once per frame
void Update () {



If your Colliders and Rigidbodies are 2d then your script needs to know that. So try this:

void OnTriggerEnter2D(Collider2D other)
