I’m using the sample assets supplied by Unity on the Asset store and I was using the 2d robot Character. I followed this video https://www.youtube.com/watch?v=UbPiCgCkHTE When I made a floor and put the box collider on it the player simply clipped through it. Am I doing something wrong?
Make sure you are not mixing 2D and 3D colliders cause they don’t work together.
