40d Talk:Trap

Cage traps clarification

I think I know the answer, but are ANY sort of cages suitable for trapping any kind of invading monster (except those that evade traps altogether, such as kobalds). The page mentions a glass trap catching a colossus, but will that also apply to a rickety wooden trap? I haven't produced any glass. --Rusty Mcloon 06:18, 29 May 2008 (EDT)

Yes. I've had a bronze colossus trapped in an Ashen Cage before. I don't think creatures care what you trap them in.--Dadamh 14:59, 29 May 2008 (EDT)

cage traps for food

Couldn't one generate a mild supplementary food source by putting cage traps out on the map at random? Or create rows of them to catch aggressive creatures that are chasing down a fleeing dwarf. The ability to place them on the surface has some interesting possibilities. Kefkakrazy 04:45, 4 November 2007 (EST)

You can really do this with any kind of trap now - I built a 1 tile wide stair/corridor up an exposed cliff face, and as I was concerned about goblins and the like I stonefall-trapped it. Ever since then some of the local wildlife has used it to get up and down the 5 z-level cliff, with predictable and hilarious results. The goats just die, but the marmots are hurled off the cliff face to splatter on the ground below. It's a nice easy meat/leather/fat source, as well as being entertaining "Dwarfy McDwarf cancels reload stone trap - interrupted by (flying) hoary marmot" Acama 19:48, 20 December 2007 (EST)

berserk dwarves

Will berserk dwarves set off pressure plates? Toady mentioned he was going to stop that from happening VengefulDonut 19:39, 4 November 2007 (EST)

On a possibly related note, pets CAN set off traps. Although in my experience the pet has to be falling unconscious to do so. Anonymousphrase 22:43, 27 May 2008 (EDT)

It may also be the case that you can also get pets killed by a trap if they're in the square when a hostile sets off the trap. —Chaos 12:42, 28 May 2008 (EDT)

flooding a spiked pit

Will flooding a spiked pit break or cancel the spike trap? I'd test this, but I don't have the channel dug in yet. --Xazak 18:30, 5 November 2007 (EST)

confirmed that flooding doesn't affect spear/spike traps. YayTheDwarves 17:52, 6 January 2008 (EST)

I'm pretty sure the "corpse stuck in trap" chance is 50%, according to Toady either on IRC or some forgotten forum post a few months back. I really can't remember for sure. -EarthquakeDamage 02:31, 10 November 2007 (EST)

cage traps/ fire imps

I've secured the entries oy my magma furnaces with cage traps, but it seems that the fire imps just walk through. Just as the Giant moles did. How so? --Doub

supposedly there is a bug that causes any creatures on the map when it is generated to count as residents, and thus know where your traps are and not trigger them. I've never run into the problem myself, but I've never specifically tested for it so I can't really say for sure if it still exists (or ever did). --BurnedToast 07:41, 6 January 2008 (EST)

I had read about this and tried it out with a trapped coridoor next to my magma vent - an imp I tempted out walked right through 4 cage traps and 4 stonefall traps without triggering them. Seems like indigenous life is currently trap-immune. Most magma creatures can be dealt with by a few marksdwarves though, so you're only in serious trouble if you have a herd of skeletal hippos on your map on embark.--TangoThree 15:42, 19 January 2008 (EST)

There's always the menacing spike + lever combo. And pits. Benitosimies 16:08, 10 March 2008 (EDT)

I've killed fire imps and magmamen with stone fall traps --Strangething 01:20, 19 July 2008 (EDT)

I've caught native fire imps in cage traps loaded with green glass terrariums. Rkyeun 21:42, 4 August 2008 (EDT)

Trolls and Cages

I'm planning on making the only passage to my fortress filled with cage traps, but I'm not sure if dwarves going out and migrants and traders coming in will be affected by them. Does anyone know? Also, do trolls smash goblin cages? Patarak 21:41, 23 January 2008 (EST)

Only hostile units will trigger traps. Trolls only smash buildings and after a goblin is captured the cage is not built. So the answer to your second question is no. --Karlito 21:45, 23 January 2008 (EST)

Make sure to forbid the traps when the siege starts. Otherwise your dwarves will rush out to reload them and store all the cages. --Ikkonoishi 22:53, 23 January 2008 (EST)

Thieves and trap avoidance

Is it possible that Kobold thieves/Goblin master thieves can also trigger traps? I think I killed one and caged another master thief in the past. Maybe the quality of the mechanism is important here? --Qwertyu 13:24, 17 March 2008 (UTC+1)

goblin thieves, both regular and master, have always triggered traps -Chariot 14:18, 17 March 2008 (EDT)

So why does the article then say "Sneaking enemies do not trigger traps"? Goblin master thieves seem very sneaky to me. --Qwertyu 20:33 17 March 2008 (UTC+1)

once goblin thieves are revealed they are captured fine. even revealed kobolds dont trigger. -Chariot 15:45, 17 March 2008 (EDT)

At least "normal" goblin thieves are scewered fine without being detected, says my weapon trap --Koltom 16:58, 17 March 2008 (EDT)

I have to agree with Koltom, I got an "Ambush" event when a goblin (master) thief went into a cage trap, and had another one cut to pieces by a serrated disc, which I only noticed when suddenly all my dwarves rushed off to remove his clothes. --Qwertyu 13:31 (UTC+1)

Weapon traps apparently have a chance of friendly fire. At least, that's what the ghost of my Kitten(tame) told me... QMarx 18:48, 13 April 2008 (EDT)

Crossbow Trap?

How does a crossbow trap work? Does it have line of sight, like a Dwarf? – unsigned comment by Lordmick134

Ranged weapons in weapon traps work much the same as melee weapons do, attacking the creature which triggered the trap. The only real difference in functionality seems to be that they require and use up appropriate ammunition, and (according to the article) do not get occasionally stuck and need cleaning like melee weapons in a weapon trap do. --Janus 21:31, 28 March 2008 (EDT)

Trapping cave dwellers

Has anyone sucessfully caged a cave dwelling megabeast? I have tried on two seperate maps to capture a minotaur and an ettin, both times the monster just run right through the cage traps. Perhaps creatures that are spawned on embark are bugged immune to traps?

Weapon Trap Jamming

The page says crossbow weapon traps don't jam, but what about a trap with a crossbow and a melee weapon? Does the crossbow still fire if the trap jams? Or does a trap have to be pure crossbows to avoid jamming? --Strangething 01:21, 19 July 2008 (EDT)

Trap betrayals?

Has anyone else been betrayed by their own traps? I had a dog and a crossbowman killed by weapons traps. Serrated iron disks ripped through their bodies like the bloody tusks of enraged elephants.

Correction. A dog, a crossbowman, and a miner. Will the slaughter never end?--Amenos42 12:08, 30 July 2008 (EDT)

I've noticed that traps tend to fire on people/animals with injuries. They've killed lots of 3 legged dogs for me, and a soldier that was dragging himself off the field.

Traps will (also) trip for any and all unconscious individuals. That may be or be one of the reasons. Drawf irons 20:53, 4 August 2008 (EDT)

Does that include dead individuals? And is it possible to get my dead dog out of his cage? --Groveller 01:32, 14 August 2008 (EDT)

Mark it for dumping? That's usually the solution as to how to get anything out of anywhere! --Raumkraut 09:34, 16 August 2008 (EDT)

Cage Trap Question

I recently received the message that there was a goblin snatcher in my fortress. It zoomed the page to one of the 3 cage traps. I took the game off pause and it gave me the same message again. Now I have two cave traps sprung, and when I press "k" and go over them, one says : "goblin cage (Larch)" and the other says "Goblin cage(nickel)". Does this mean I have successfully caught the scoundrels? Or are they still at large?

If there is a flashing 'g' then yes, if no than It could be possibly a bug.Hoborobo 08:25, 10 August 2008 (EDT)

Stone Fall Update: Watch Out!!

This is as of release 0.28.181.39f: in the past hour I saw two of my own dwarves - both normal healthy members of society - get killed in two different stone fall traps I'd had set up. Clearly, the old rule that dwarves are immune to their own traps is no longer entirely accurate...unless there's a bug going on here? Has anyone else fallen prey to this occurrence? Grand marquis 06:31, 16 August 2008 (EDT)

See two sections up. :P Anything unconscious will trigger traps currently - did those dwarves fall asleep on the trap square maybe? I've changed the section on triggering traps, so it gives at least a little hint that backfiring is now possible! --Raumkraut 09:33, 16 August 2008 (EDT)
