Question by Oninji · Dec 15, 2011 at 05:25 AM · javascriptcollisioncolliderdamage

Cannot detection collision

Greetings, I'm scripting a sword hit to apply damage. The problem is that Unity does not detect any collision.

Here's the test script,

     var damageAmount = 20;
 var isHitting : boolean = false;
 
 function OnCollisionEnter (collision : Collision) {
     isHitting = true;
     
     if (collision.gameObject.GetComponent(Tagger).canBeHit == true){
         collision.gameObject.SendMessage("applyDamage", damageAmount, SendMessageOptions.DontRequireReceiver);
     }
 
 }


For some weird reasons, the isHitting boolean does not turn true. Both my object that have the script and the one I hit have a collider.

Does at least one of the colliders also has a non kinematic rigidbody attached? Maybe the problem relies on the absense of it.

Try adding a rigidbody to your object, unless you have. Just moving a collider around won't trigger collisions. It has to be a rigidbody on either end of the collision. If you don't want it affected by physics, set it to kinematic in the inspector. This should enable your collision callbacks.
