Hi odinn,
You are not doing anything wrong. The head collider is a trigger collider.
Actually, Rick’s Barry should have dived into the ground instead of bouncing off. In later videos, you can see, that he doesn’t bounce anymore. Rick suspects that the surface effector made the head bounce in this case. Sometimes, there are undesired side-effects, and since we didn’t write the Collider2D classes or the surface effector class ourselves, we cannot prevent those side-effects.
Did this clear it up for you?
