Question by b_schwartz · Aug 29, 2017 at 04:00 PM · collisioncollision detectionontriggerenter

OnTriggerEnter only works on one collision?

I have an OnTriggerEnter function with two objects set to detect collision.

Both have a tagged hitbox and attackbox, both with colliders set to trigger, and only the Player seems to be detecting collisions. I have tried setting kinematic rigidbodies on either, and both. Both are on the default layer, with collision set on it.

I really don't see what the problem could be. Again, I AM getting the "Enemy Takes Damage", so the function is obviously working, just not for both.

     public bool knockDownAttack;
     public float attackStrength;
 
     public GameObject otherObject;
 
     void OnTriggerEnter (Collider other)
     {
         if (gameObject.tag == "PlayerAttackBox" && other.tag == "EnemyHitBox")
         {
             EnemyTakeDamage();
         } 
 
         else if (gameObject.tag == "EnemyAttackBox" && other.tag == "PlayerHitBox")
         {
             PlayerTakeDamage();
         }
         else
         {
             return;
         }
     }
 
     void EnemyTakeDamage()
     {
         Debug.Log("Enemy takes damage");
     }
 
     void PlayerTakeDamage()
     {
         Debug.Log("Player takes damage");
     }

Did this ever get resolved? I have a similar issue where I am trying to instantiate a particle effect on collision on two different objects, but only one works at a time.

 void OnTriggerEnter2D(Collider2D other){
 
         if (other.tag == "Wall") {
             Instantiate (CannonSplosion, other.transform.position, other.transform.rotation);
             Destroy (this.gameObject); 
         }
 
         if (other.tag == "Player") {
             Instantiate (CannonSplosion, other.transform.position, other.transform.rotation);
             Destroy (this.gameObject); 
         }
     }

It only seems to instantiate the particle effect when it hits the player, but not the wall/ground of my tilemap.
