Question by DannyBacon · Oct 04, 2018 at 06:37 PM · collisionlayersdetectionhow-to

How to check the collision layer on collision event?

I'm sorry, I know this is basic stuff, but I can't find up to date answers ANYWHERE!!! :P

I have a collision event already set up, but it will fire for anyt$$anonymous$$ng it collides with. I only want it to react to a specific collision layer. How do I do it?

Here's an answer from 2012, but it doesn't seem to work anymore: https://answers.unity.com/questions/261556/how-to-tell-if-my-character-$$anonymous$$t-a-collider-of-a-ce.html

There's no reason it shouldn't work - the Collider object still can access the GameObject it is attached to and in turn its layer:

void OnCollisionEnter(Collision collision) {
    Debug.Log(collision.collider.gameObject.layer);
}


Check if you have your layer set up on the GameObject that contains the collider component. Maybe you've set up the layer on a parent object and not its children?
