The boxes are standing right next to each other, but somehow, the player manages to collide with the ghost edge. I use
AddForce to control the player with a Box Collider, though I also tried using a Mesh Collider, and I tried setting the player's collision to continuous. This also happens in 2D.
I've seen other people's posts about this bug, but I couldn't really understand how to fix it. How do I fix this?
