Yo Nathan, sorry to bother, but I can't for my life make this work 😭
I made these spells:

and
https://pastebin.pl/view/ddb77489

They work combined to make a wall slide and wall jump. I wanted to make so when the player jumped (triggered on unsneak the main problem here) would push him from the wall, but nothing I did works 😭. It targets the blocks in a ring arround the player, using AOE wouldn't target the player no matter what I did. Tried some obscure parameters like "source_at_target" and "source_is_target", but couldn't make it work.
