Paintball GUN

Mam tu taki kod, który zmienia bloki w gline, a po 3 sekundach spowrotem w poprzedni blok. Niby wszystko okey, ale glina zostaję i nie zmienia się w poprzedni blok

on projectile hit:	if projectile is snowball:		set {_loc} to location of block at projectile		loop all blocks in radius 4 around {_loc}:			if loop-block isn't air:				set {_paintball::%location of loop-block%} to loop-block				broadcast "%location of loop-block% | %{_paintball::%location of loop-block%}%"				set loop-block to 159:1		wait 3 seconds		loop all blocks in radius 4 around {_loc}:			set loop-block to {_paintball::%location of loop-block%}
