Bay 12 Games Forum

So im trying to force nethercap to spawn in an area after the game has started, been poking around for two days and all ive found is this code from 2014

feat = df.global.world.cur_savegame.map_features[2]
num = #feat.feature.population
feat.feature.population:insert('#', { new = df.world_population, type = df.world_population_type.Tree, plant = dfhack.matinfo.find('PLANT:NETHER_CAP').index });
for i,j in pairs(df.global.world.populations) do if (j.population.cave_id == feat.layer and j.population.population_idx == num - 1) then df.global.world.populations:insert('#', { new = df.local_population, type = df.world_population_type.Tree, plant = dfhack.matinfo.find('PLANT:NETHER_CAP').index, population = {region_x = j.population.region_x, region_y = j.population.region_y, population_idx = num, cave_id = feat.layer, depth = feat.start_depth, unk_28 = -1 } } ) end end

Which claims to do exactly what Im trying to do, but i get this error

...\DWARFF~1\Dwarf Fortress 0.44.12/hack/scripts/nether.lua:1: Cannot read field world.T_cur_savegame.map_features: not found.
stack traceback:

        (...tail calls...)

I dont understand programming enough to understand what this is doing, or what the error is. Could someone help explain this to me? Or alternately direct me to a better tool to introduce biome/cavern appropriate trees/saplings/spores to an area? Its taken me nearly 4 days to generate a world i have any interest in playing in long term, and the only thing i lack is nethercap for a project. Thank you in advance, I hope this is the right forum.

Link to previous post on same topic I found. incase ive made a mistake or explained poorly.

Ive shot this troll with like 40 iron bolts, the most its done was bruise their left cheek. Does skill impact damage too, or is troll skin just tougher than iron?

So, my surface forest caught on fire, and amid the spam of "something collapsed on the surface" suddenly like half of my fort was knocked out, i go to look, something smashed a hole straight down several floors, through solid basalt, and now my fort is full of smoke. Ive seen chopped down trees leave a single space hole in the ground, but im not chopping anything, and that doesnt explain why its a several floor deep hole. If my whole surface operating as a giant cave in piston trap thing?

Edit: its also completely destroyed several stockpiles, and a farm, this is stupid. I could see it messing up the top level, but not like 3-4 floors down through solid stone, its a tree, not a bomb.

Hey, I asked this over on dwarf mode forum, they suggested I come here. Im planning to temporarily retire a fortress im playing and make an adventurer from it, send them to raid a nearby necromancer tower and steal the slab, bring it back to my fortress to make more necromancers. It will be my first attempt at adventure mode. How hard is it to get in and steal a slab? Does taking the slab disrupt the towers operations? Is it always on a necromancer? Id be fine if my fort still got attacked by the undead, I just want my own necromancers for live training, and imprisoned ones go insane eventually, means ill run out someday.

My goal is building a pond that fills up to 3/7 (thats still pathable right?),to use as a bath house, little soap stockpile pretty much just because, a well, if possible setting up a mist generator in the entrance (could use the water that fills the tub?), and ideally, filling the room with steam (unless this will like, tank fps in which case I wont bother), and designating it a meeting hall or sculpture garden so dwarves will go in and get cleaned up every so often.

So, questions are I guess, how many squares of 3/7 water are made per square of 7/7?
Is that even how liquids work?
How big can the pool reasonably be?
Instead of the mist generator, can I just make the water fall from above into the pool?
How to do it with minimal pumps?

If I understand correctly, you stick them in a windowed room with a bridge to turn it on and off by blocking their view, fill the room the windows look towards with corpses and use it for live training? Is it safe to build up a second floor and surround that in fortifications? or can the undead climb out or anything like that? Would it be particularly effective to use the corpses of my own dwarves? Or are all corpses equally durable?

So I see in the wiki it says that visitors might side with their civ if it attacks you, just reporting that this does indeed happen, just had a bunch of bards attack my tavern when the humans id been waiting for caravans from attacked with....6 guys. My 10 hammer lords beat them all to death, and stray dogs mauled the bards to death. I have to wonder why they even attacked when it was so hopeless. No idea if the game models "is this a good idea or not?" though in such decision making.

Caught myself some armadillos, wiki tells me they produce shells, and im trying to breed them, while getting them into their own room, a cave croc I was training got lose and spooked one, its been "overcome by terror" for about 2 months now, they also havent bred at all, which could obviously take longer than 2 months, I just wanted to make sure I dont have to like, catch another one because this ones too upset to breed or something. Neither was injured, they were just present while a dwarf choked a crocodile to death far as I can tell.
