Animation plays for every instance of an object

Questions & Answers

I created a method for detect clicking on an object in scene and play a animation attached to a canvas
the code is :

 if (Input.GetMouseButtonDown(0))
             {
                 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
                 RaycastHit hit;
     
                 if (Physics.Raycast(ray, out hit, 1000, TurretSellLayer))
                 {
                      anim.SetTrigger("Luanch");
                     Debug.Log("Noooooooooooooow");
                 }
                 
             }

the code works fine but when ever i click one of them , animation plays for every instantiated prefab in the scene

You should google it, this is a common objective, odds are someone’s asked it before… you need to check against the specific instance somehow, such as checking the name:

Not sure if every instantiation would have a unique name off-hand, if not you may have to set each on creation to use name, or use some other variable or whatever feels good… probably the cleanest way is something like: if (hit.gameObject == gameObject) etc.

If you’re attaching this script to all your instantiated objects then it’s normal that you’re having this behavior, since you’re only checking for Input.GetMouseButtonDown and it’s called for every object that has this script attached.

If instead you’ve attached this script to one only object in the scene then may be that your ‘anim’ member is a reference to the original prefab, in which case it’s also ‘normal’ how it behaves since the changes to a prefab is reflected in all its instances.

@Seth-Bergman Thanks a lot
RaycastHit does not contain a definition for gameObject but you gave me the Idea and now I am checking for its transform and works like a charm
Thanks again
