[Help] Guitar Hero-esque code not working.

Code (CSharp):

1.     void OnTriggerStay2D (Collider2D other) {
2.         Debug.Log("Test");
3.         if (Input.GetKeyDown("D"))
4.         {
5.             if (other.gameObject.tag == "ZoneWin")
6.  
7.             {
8.                 Destroy(gameObject);
9.             }
10.         }
11.        
12.     }
13. }

I have the correct tags, correct everything as far as I can see. However, my gameObject just passes through the other sprite I put in. (This code is on the object that I am Instantiating.)

 

does something involved have a rigidbody2d attached?

 

Yes, my "ZoneWin" sprite has a rigid body.
