CharacterController:disable character-to-character collision

Question

I was wondering if there was a way to disable character collision when using CharacterController.

I still want all other collision detection (terrain etc) but when colliding with other CharacterControllers, I'd like that collision ignored.

Any idea?

You can make a script that you attach to a single game object (for which there's just going to be one instance) and you put the following code in the Start function of the script :

void Start() {

         UnityEngine.Object[] characterControllers = GameObject.FindObjectsOfTypeAll(typeof(CharacterController));

         System.Collections.ArrayList existingCCColliders = new System.Collections.ArrayList();

         foreach (CharacterController charController in characterControllers)
         {
             Component[] colliders = charController.GetComponents(typeof(Collider));

             foreach (Collider collider in colliders)
             {
                 foreach (Collider existingCollider in existingCCColliders)
                 {
                     Physics.IgnoreCollision(collider, existingCollider);
                 }
             }
         }

}

Now there are probaly bugs in this code.It's just the logic, I haven't tested it. But the idea should work. and maybe you'll have to replace the arraylist by some other type of collection as I don't remember if arraylists are supported in Indie.

function Start() { ignoreCollision("Player"); }

function ignoreCollision(tag: String) { var objects = GameObject.FindGameObjectsWithTag(tag); for (o in objects) { if (o.GetComponent("Collider") && o != gameObject) Physics.IgnoreCollision(collider, o.collider); } }

just editing the post above me.
