I would like to know how to implement a system that allows a tile to be passed through from below. That is, I want to be able to walk freely beneath it, but when jumping through it, I should be able to land on top of it. This means the tile's hitbox should only activate when the character is above it, but not when below. I want to create scalable vertical platforms with jumps, similar to those in the classic arcade Snow Bros.
I appreciate your responses and your help.
