How can I tell what prefabs a child object (script) is in?

This isn't a stupid question: I had this problem many and many times too - so many times that I finally created a simple way to find it. Attach this line to Start in the script you want to find (all instances will be affected):

function Start(){
    print("I am in "+name);
    ...
}

This will print the name of each object containing this script. If you have lots of objects with the same name, however, you may need some visual aid. Call this function inside Start:

function IAmHere(){ while (true){ Debug.DrawRay(transform.position, 20*Vector3.up, Color.red); yield; } }

function Start(){ IAmHere(); ... } This will show a 20 m red line over each object containing the script (remember to click the button Gizmos over the Game view, or nothing will be drawn).
