Question by Tageos · Jul 28, 2015 at 10:51 PM · c#collider

Only use specific collider

Hello!

So what i want to do is make an enemy do stuff only when a 2D collider attached to a bullet gameobject touches the enemy. Now the enemy will react to every collider that touches him. How would i go about to fix this?

 void OnTriggerEnter2D (Collider2D other) {
         Debug.Log ("Zombie Hit");
     }

Thank you!

/Taegos

Set tag on enemy to " Enemy "

 void OnTriggerEnter2D (Collider2D other) {
             if (other.gameObject.CompareTag("Enemy")) {
                 Debug.Log ("Zombie Hit");
             }
         }

Thank you, but if 2 enemies collide with each other i get this message. I only want "Zombie Hit" if it is the bullet that hits them. This is a step on the way though, thank you :)

Ohh, so the script is attached to the Enemy? in that case tag bullet as " Bullet " and if (other.gameObject.CompareTag("Bullet")) or by its name if (other.gameObject.name == "bullet")

I'm new to unity as well so I'm not so sure but I believe you can use the Tag function. Attach a tag called bullet to the bullet and then do something like this.

  void OnTriggerEnter2D (Collider2D other) {
 if(other.CompareTag("Bullet"))
          Debug.Log ("Zombie Hit");
      }
