Hey!
I’m trying to create a Super Smash Bros-style mechanic where getting hit by an enemy’s pickaxe increases a percentage, and the higher that percentage, the more knockback you take.
I’ve been looking for a way to implement this, but I haven’t had any luck so far. Does anyone know how to do it?
Thanks in advance! 
How many weapons you have on your map ? If you don’t have a lot, you could use conditional buttons to check that the damager player is not holding any of them upon dealing damage (which would mean they’re holding the pickaxe)
You could also add a distance check if you want
Then either use a pool of explosive devices or remotely activated movement manipulators to bump the damaged player away from the damager player
Got it, thank you!
