These are nice ideas but...
we can still push the boundaries of !!SCIENCE!!
I use the following plan regularly (aka. all the time) and it has never failed yet.
After making my first large scale, large time, mega engraved danger-room I thought there has to be a better way.
This is what I thought up of. (And yes, i confirm quality spears cause problems)
####### #####
#L #|DW# -OR- L#|DW#
##D#### D####
- # = Wall
- L = Lever
- D = Door
- W = Weapon Rack/Armor stand/etc
- | = Upright Spikes
Its super efficient and super cheap. The lever is connected to the spikes (10 tower-cap spears), the outer door is no-pets (to avoid cat-splotion! Or not...), the inner door is internal, no-pets and forbidden. Finally the barracks is made. Because only the tile w/ the spikes is accessible, dwarfs will never dodge to "safe" squares, 'cause there are none! I will also not that this does NOT stop dwarfs training dodge, if anything it is faster because they are always "under attack". Also this is super cheap w/ only,
2x doors
10x no-quality wood spears
3x mechanisms
1x armorstand (what I use)
PS - I like to
import 10 tower-cap spears because A: Its dwarfy B: No issues with no-quality carpenters!
PPS - This is my first post w00t!
I've been lurking since the 40d days but with the resent dev-log, I couldn't wait any longer!
