Cool waterfalls - how?
« on: August 16, 2010, 06:52:19 am »

I want to liven up my main meeting hall by adding some cycling waterfalls - or rather one waterfall that falls through different holes in the ceiling.

The main setup is pretty simple - a reservoir, some pumps, some floodgates, a drainage system. What I am having trouble with is a clock system that opens/closes ceiling floodgates.

What I initially planned was something like this:

Code: [Select]

#########
#........  <-- pressurized water comes from here
#+#+#+#/#
#o#o#o#o#  +, / - closed/opened floodgate, o - pressure plate
#+#+#+#+#
........#  <-- surplus water drains down there
#########


The idea is: water floods the rightmost chamber, when some critical level is reached, pressure plate triggers and 1) intake floodgate closes, 2) drainage floodgate opens, 3) intake floodgate of the next chamber opens, 4) one waterfall floodgate opens, one closes. Repeat with the next chamber.

The problem is pressure plates can't seem to be set to open one thing and close another at the same time, so there goes this design.

What can I do to make it work?

you only need 1 tile of water, to make a waterfall / mist generator.

Make this at level 0, where you want the waterfall:

Code: [Select]
....   . = floor
....   # = wall
..##
..#.

then at z+1, dig a channel above the walled-off 1x1 area below, designate a pit, and set it to be a pond. Your dwarves will fill it up to 6/7 water. Undesignate the pit when there's 6/7 in it.

Now, dig channels in the other corners of z+1, and place pomps, and power:

Code: [Select]
_>>_   >v<^ = pump (direction)
^ggv   _ = channel
^.gv   g = gear assembly
_<<_
Once it's powered, you'll have a nice mist generator, giving your dwarves happy thoughts. You can remove the walls around the initial pond at z=0 once it runs.
Once in a while, your dwarves will get spammed by a job cancellation, dangerous terrain. You can prevent this by building statues below the channels. As long as it stays powered, it will never run out of water, the 6/7 block of water will keep jumping around indefinitly.

Ofcourse, you can make the design larger if you want, by adding more pumps and channels.

Or, to make your own idea work, instead of using 1 pressure plate, use 2 pressure plates per reservoir. One, to close the intake, one to open the outlet, and the next gate

You can pressurize water like the rl miners used to do wow didnt know that.

Look at the designs on the wiki for repeaters.  They use a flood gate and a 1x1 drawbridge attached to the same lever.  This is because their open and close states are opposite each other.
