So I'm trying to do griffpatch's platformer tutorial and I'm only halfway through the wall sliding chapter on his video on youtube.
I think I misplaced or forgot a block, cuz when I jump I can jump mid-air. I tried fixing it through this block

but wallsliding didn't work so I used the original one and hoped it would somehow fix itself later and used this

but wallsliding didnt work on it either.

If someone can fix, pls help
