OnCollisionEnter Issue...

[anon4796025]

Ahoy! I’m having an issue detecting a collision driven by an enemy player. Below is the basic set-up:

• Player is a static collider tagged “PlayerCollider”
• Enemy is a rigged / animated (Cinema4D) import with a sword as a child of the last joint (hand)

Issue: When enemy animation swings sword, the collider (+ the script below) does not detect a collision (rigidbody projectiles seem to detect just fine)

var glassCrackParticle : GameObject;
    
    function OnCollisionEnter( collision : Collision ) {
    	if(collision.gameObject.tag == "PlayerCollider"){
    		print("sword hit");
    		var contact : ContactPoint = collision.contacts[0];
    		var rotation = Quaternion.FromToRotation( Vector3.up, contact.normal);
    		var instantiatedExplosion : GameObject = Instantiate(glassCrackParticle, contact.point, rotation);
    	}
    }

Is there something to animated rigs with weapons attached to them don’t detect quite right?

Thanks in advance

Try adding a RigidBody set to Kinematic to the moving collider. If you don’t do that, Unity physics will think both colliders are static and never check for them colliding. Setting the IsKinematic flag of the rigidbody basically tells Unity this collider is moved by script or animation, and to perform proper collision checks on it.
