I'm...probably going to shamelessly copy that because that looks and sounds brilliant. How will you deal with skeletons that spawn though? Won't they shoot through the half blocks?
Yes, skeletons shoot through the blocks because they are assholes and ruin everything. It's simple enough to kill them though if you move quickly. They can't chase you and have barely any room to work with so it's a simple thing to do.
The only way I could get the skeletons to not shoot you would be to redesign the prison to use blocks that obscure sight. This defeats the purpose of the prison though. You would have to use glass, which doesn't look very good for a prison. You also couldn't put a door in, as they can see and shoot through doors.
I'm not going to let some skeletons stop me from building it though.
