Raycast hits wrong object

Questions & Answers

Hello,

I have a scene with 3 Objects (all of the same Prefab type):

The prefab has a script that checks if the player clicked on the object:

void Update() {
   if(Input.GetMouseButtonDown(0)) {
      Debug.Log("MouseDown");
      Ray ray = camera.ScreenPointToRay(Input.mousePosition);
      RaycastHit raycastHit;
      if(Physics.Raycast(ray, out raycastHit) && raycastHit.collider.gameObject.tag == "Magnet") {
         GameObject go = raycastHit.collider.gameObject;
         Debug.Log("Hit object: " + go.name);
         ...

The problem is: When I click ONCE on ONE object, I get the hit 3 times! This is the output when I click ONCE on one object:

How is it possible that I hit all 3 objects (when the ray clearly only intersects the geometry of ONE object)?

Damn, I just found the problem! For all people that run into a similar problem: I hit the SAME object 3 times cause the code was executed 3 times and found the same hit every time.

Guess its not a good idea to have Scripts on objects that are multiple times in the scene?
