Fireball not destory when touching wall a bit, but destroy when totally hits wall (OnTriggerStay ?)

Hello,

my wizard is Shooting a FIREBALL, which has a sphere collider and it's own class.

When the FIREBALL hits a wall but only touching it a Little bit, I would like to continue, but when it totally flies straight into the wall, I want to destory it.

This Code is working so far that the FIREBALL is destroyed every time, how can I have it continue when it just touches it a bit?

Code (CSharp):

1.  void OnTriggerStay (Collider other)
2.  {
3.   //Debug.LogWarning (string.Format ("Bullet Triggerstay with {0}", other.gameObject));
4.   if (!other.gameObject.CompareTag ("Monster") && !other.gameObject.CompareTag ("Animal") && !other.gameObject.CompareTag ("FurBall")) {
5.    Destroy (gameObject);
6.   }
7.  }

Thanks a lot

 

Make the fireball's collider smaller.

 

Then it is harder to hit Monsters or it Looks like hitting Monsters, but it does not.
Or not?

 

How about separate collider for walls and for monsters?

 

Good idea. I just tested I can have two colliders in one object, put them into public variables and check each one then.
I will add a smaller one for walls!

Thanks for the idea
