RAAGH! So I get the brilliant idea to chain up this elf crossbow-zombie I caught during a siege as a kind of infinite ammo auto-turret, which is the only part that worked well out of this whole thing.. too well..
I want that zombie back in a cage! :| Here's the setup, resplendent with high-definition detailed hand-labelled schemata:
On the right is the bottom/ground floor, left image is one z-level up and above the nest box room. Pictured is the charming elfzomb on a gold chain with a bridge to the right that can be lowered so the zombie has visibility to fire downward and eastward over my fort entrances.. I realized very shortly after chaining him there (he shot the dwarf that chained him in the ass before he could dive back downstairs..) that he was going to be a disruptive force..
For a while he served as a pretty decent kea repellent, but I hadn't thought that he's on my 2nd z-level and was going to shoot at any life-form who dared try and build above the 2nd floor since that zombie room was roofless.. I've since broken down and made an obsidian roof using dfhack over the northern portion of the room so my construction can continue.. At first I tried making a single obsidian tile suspended in the air above the zombie's chain, hoping the block would fall and punch the chain through the floor, setting the zombie free, but the tile of obsidian also spawns with its own flooring/support and won't fall.. (dfhack needs a function for dropping projectiles! And for abusing extracts/blood/fluids/syndromes..)
For a second I hoped that maybe I'd constructed the chain on a tile that was created by the central walls in the nest box room below, so I could dismantle that wall on z-1 and destroy the floor on z-2, but its built on a dwarf-built floor tile
I've even considered dfhack-dropping a tile of magma in there and burning him free, but there is quite a bit of raw wooden fort around that room (and around the whole complex) and I already had a tough time using dfhack-water to extinguish a forest fire..
Can I deconstruct or otherwise destroy the tile his chain is on from below, or use some secret dfhack trick I don't know about? I've already got cage traps set up to collect him no matter what direction he goes once set free, so that's handled.. I deconstructed the staircase that led up there so that invaders (or my own dwarves) couldn't climb up there and kill him once he started firing.. I just want him back alive (or as alive as a zomb can be..) so I can install him in a proper 3-z-level tall bridge-walled turret-box
with a roof..
