Prefab Duplication issue

Questions & Answers

The prefab is a hazard, and when the ball collides with the trigger, it triggers the game over panel.

However, only the last prefab dragged into the hierarchy does this correctly, not all of them.

The prefab has the ‘GameOver’ script attatched:

    public void OnTriggerEnter(Collider collider)
    {
        if (collider.tag == "Player")
        {
            //gameOver
            gameOver = true;
            //disable mesh
            collider.gameObject.GetComponent<MeshRenderer>().enabled = false;
            //freeze pos
            PlayerController.instance.playerRb.constraints = RigidbodyConstraints.FreezeAll;
            //disable move buttons
            foreach (GameObject buttons in MoveButtons)
            {
                buttons.SetActive(false);
            }
            //instantiate explosion
            Instantiate(playerExplosion, collider.transform.position, Quaternion.identity);

        }     
    }
}

And the GameManager has the following:

	public void Update ()
    {
        isGameOver = GameOver.instance.gameOver;

        //check for game over
        if (isGameOver)
        {
            gameOverPanel.SetActive(true);
        }
    }

Why does this only work for the last placed prefab ? any thoughts ?

Here is a video of the problem -

Ok, it seems like your GameOver script has a static instance. You cannot have a static instance of a script that is on multiple objects! If that’s the case then each next object with this component overwrite the instance with a reference to itself, that’s why only the last one works

Make your gameOver field ‘public static’ and reference it instead.

     public void Update ()
     {
         isGameOver = GameOver.gameOver;
 
         //check for game over
         if (isGameOver)
         {
             gameOverPanel.SetActive(true);
         }
     }
