DF Dwarf Mode Discussion / Re: Sealed Liquid Trap Hallway Design Question
« on: April 22, 2012, 11:21:12 pm »... You've not implemented the solution that I suggested. The way you've described, with 1 pump, obviously won't work. I'm talking about using 20 pumps for a 10-long 2-wide hallway so that every single tile in the hallway is a pump input tile. If there are no adjacent 2/7 non-pumped tiles to flow into the pumped tiles, no 1/7-depth tiles will appear and you have no problem.
I've tried what you describe both with 22 adjacent pumps and 3 adjacent pumps, and there are still cases in both sets of adjacency where 1/7 magma stubbornly refuses to disappear, with all the surrounding tiles starting out at 7/7. Believe me, if it worked, I would use it. As you've outlined, it would effectively only permit a 2-tile path width, which is more limiting that what I have now, which works (minus the evaporation problem) with up to a 9 width path. In other words, I would rather wait for 1/7 evaporation than be limited to a 2-tile path. Right now, the larger I make my hallway, the better it works, so I'd rather keep going in that direction rather than smaller. It just requires more mechanisms.
You seem to be making this more difficult than it really needs to be... Why is the whole floor covered in pressure plates?It's not. As you can see from the video linked in my sig, it's a single row of 9 pressure plates surrounded by bridge-floor.
instead of trying to fill the walkable pathway with magma, have a ton of pumps constantly dropping it in from above, and make a majority of the floor grates that feed magma back into the system?The pressure plates are triggering the automated system. When an enemy walks over it, it seals the hallway, fills it with magma, waits for it to be full; once full it empties the hallway, unseals it, and waits for the next batch of victims. Entirely automatically, with no manual intervention of any kind.
I also do not see what role the pressure plates play at all.
It is neither necessary nor desirable to have your pressure plates inside the area to be sealed off. Put the triggered plates just *outside* the sealed-off area.
I've tried that. The problem is, when the pressure plate is triggering an automated sequence, retriggering it will create a situation whereby creatures outside the sealed area will keep the trap in a state of perpetual "on/start" and it will never reset/empty. (they keep stepping on it) I've tried them outside, and it didn't work for me. But if I could, I would.
I've tried isolating the pressure plate outside the hallway, but eventually, just one creature gets sealed in there with it, and keeps retriggering it. Annoying, those pesky enemies.
As I've been working with mods that heavily use trap-avoiding enemies for 2 1/2+ years, I've not really developed skills for pressure plate use, instead using lever-triggered architectural traps.
