Not sure what happened, but when I went to test if my character could jump on certain platforms, or if I have to move them, my character refuses to jump. I am using tilemaps and have a tilemap collider. (I’m using https://maaot.itch.io/mossy-cavern). So, I am not sure if that is the cause. Everything was working just fine before I started to make the edits in Part 5, and creating my scene.
EDIT: So, if you’re reading this, and having the same issue, make sure you remember to set your ground and platforms to the “Ground” Layer in the inspector. I don’t want to tell you how long it took me to figure that out.
