2d OnMouse(anything) Not working

Question

So I want to be able to click on these targets and have them destroy themselves. Right now I have many OnMouse functions all just trying to print something for testing. For whatever reason it doesn't fire. I'm sure theres something simple I'm missing. Anyones help is greatly appreciated. Here is a picture of Unity itself and the code.

using UnityEngine;
using System.Collections;

public class TargetLogic : MonoBehaviour 
{

    // Use this for initialization
    void Start () 
    {

    }

    // Update is called once per frame
    void Update ()
    {
        //print("ok");
    }

    void OnMouseDown()
    {
        print("Works");
    }
    void OnMouseEnter()
    {
        print("Enter");
    }
    void OnMouseUp()
    {
        print("up");
    }
    void OnMouseOver()
    {
        print("Over");
    }
}

I also Have tried with a 2d Rigidbody as shown here

Answer 1

I see nothing wrong with your first setup, the only thing that may interfere could be another object over (in Z space) your target, with a collider attached to it.

The first collider in Z space is the one that get's the mouse events.

So try to disable everything except the MainCamera, the Light and your target, if it is working then there is something that overlaps your target, and this object is getting the mouse events.
