I'm fairly sure they're possible with DF - lots of pressure plates, methinks - but has anyone ever made one with his/her fortress?

[Jakkarra]

not as of yet, but im going to make one for my adventurer fort for that competition thingie.

there will be a LOT of magma.  (with an auto-reset, so it can happen moar than once).

[yaklin]

what is this "goldberg machine"?

[Jim Groovester]

Google Rube Goldberg machines.

They're those overly complicated, over-engineered devices with multiple steps that perform simple tasks. The only example I can think of off the top of my head is in the third Back to the Future movie; Doc Brown has one to cook eggs.

They're also in at least one of the Honey I Shrunk the Kids movies as well. They're in lots of media, so I'm sure you've seen at least one.

I think my entire fort qualifies as that. The simple task is redistributing wealth from the goblins and elves to the humans and dwarves. It takes a 150+ dwarf fort to do so.

[yaklin]

ok, now that i know what they are i have seen some and doc didnt use the machine to cook eggs it was used to make ice

[ArkDelgato]

Dwarven breakfast machine!

simplified of course.
it could contain gobbo's, water and fireimps.

[Aldaris]

For those that don't knowof Goldberg machines, go and watch one of the newer wallace and gromits

Has anyone contrived an obsidian collapsing ceiling trap that automatically creates the next layer of obsidian to drop and resets?  I can't think of an effective way to dispose of the fallen obsidian automatically, though.

Drop it in magma?

[Kilo24]

That would work, but would take out whatever constructions were in the way so you couldn't crush anyone beneath it again.  You might be able to create a collapsing floor, but it wouldn't be better than a simple retractable bridge.

i had tougth about it a bit (for creating automatic obsidian rock making machine) but i think it is now impossible to make ... or at least i dont see how ... the main problems are:

• Opening-closing bridge in obsidian wont break it (kind a wierd but it just opens and is still encrusted in obsidian)
• Making a cave-in based machine hase two main dificulties too:
• cave-in stops game (it is anoying)
• you virtualy cant make unsupported obsidian, one of its edge qwill be in contact with something next to it cause you need thet to make bridges

[Jakkarra]

speaking of obsidian, and RGMs, i usually use an obsidian creating system to seal adventurers into my Adventure-forts.

It goes a little like this. Note, this is a cross-section

...F...F....           L

S=rock
M=MAGMA!
H=hatch
W=Water
F=floodgate
.=Floor
L=lever(attached to the floodgates,and hatches/retracting bridges, i cant quite remember)

Basically, when the lever is pulled, it causes the floodgates to close, the magma and wather to fall, these then solidify on contact with each other, sealing the adventurers into the fort (theres another way out, obviously) the lever also opens up the remainder of the fort

there are virtually no downsides to this, unless of course, a companion gets fossilised.



Love, jakkarra

So what's the downside?

[LegoLord]

I just had a stroke of brilliance!

Code: [Select]

  MMM
  %%%
WW%%%WW
W.....W
WW%%%WW
  %%%
  HHH
% = pump
W= wall
H=water channel
M=magma channel
 . = open space

The open space would need to be more than on z-level above the target.  Both pumps could be hooked up to gear assemblies and levers so that they only pump when a lever is pulled or a pressure plate is triggered.  Then, when this happens, they both go off at the same time.  Having a mechanical power source is necessary, as the impassible space would need to be built over an open space tile.
