I ran into an Issue when trying to use the Box Collider for jumping and climbing, and after a few trials I found out that sometimes after i would fall a big distance (off the ladder or from the mushroom) I would partially Clip through the floor preventing me from jumping or climbing.
A solution I found was to check the “Is Trigger” box for the Feet (BoxCollider2D). This made it so everything now works, I cant wall jump, I don’t clip through the floor anymore, but can still climb and jump.
Figured I’d post this just in case anyone in the future has trouble with this, this may be a solution for them as well.
Edit: As a side note I am currently using Unity 2021.2.3f1
