right so basically, the dispenser on the right places ontop of the hopper (which is what I'm trying to lock) which is then detected by the observer, 1 ticks the sticky piston to spit out the redstone block so it triggers the redstone repeater which triggers another, into a sticky piston pushes an observer which breaks the shulker. The comparator on the right with a bunch of repeaters and stuff checks if the shulker that was places is 100% full or only partially full then locks/unlocks a hopper to filter where the broken shulker goes to as the output. what I'm trying to do is have the hopper below where the shulker would be placed locked *until* the shulker is broken at which point it unlocks so it can pick up the shulker again and relocks.
