Question by BlackShadow · May 26, 2014 at 04:20 PM · collisioncolliderbox collidercontactcontact.point

How do I find the point of contact on a box collider?

I'm performing a little bit of simple practice in unity. As a start I'm trying to recreate pong as a start. But I ran into a little problem, what I want to do is have the ball go in a certain direction depending on where the collision happened. I tried using contact points, but the point seems to be the world position instead of the collision on the box, I was wondering if there was a method I'm missing that gives the contact point on the box instead of the world.

Take the world point and use Transform.InverseTransformPoint() to get a point relative to the object. Something like:

  var localPos = transform.InverseTransformPoint(col.contacts[0].point);
