Unity 5，销毁（game.Object）

Question

I just started to make 2D game for myself, I've got a problem. I have a gameObject moving through the sreen from right to the left, I need to destroy it when it leaves the screen. I've created "object_killer", added BoxCollider2D component, IsTrigger. This is my small script (C#):

 void OnTriggerEnter (Collider other)
    {
           if (other.tag == "rektcar")
            {
            Destroy(gameObject);
            }
    }

But nothing happens - my gameObject is moving far away from the screen. "object_killer" has rektcar tag.

Answer 1

Do both of the colliding objects have a 2D collider? Also, if you're making a 2D game with 2D colliders use

OnTriggerEnter2D(Collider2D) {  }

Answer 2

Since you've used OnTriggerEnter you should make sure your object has selected IsTrigger property. If you don't want to use trigger you can change OnTriggerEnter to OnCollisionEnter .
