DF Dwarf Mode Discussion / Interesting things when attempting to build underwater fortresses
« on: February 07, 2009, 01:33:22 am »
Hi all.
I was attempting to build an underwater fortress. But rather than the drain the ocean method, I decided to pump vast volumes of lava into the ocean, in the hope of carving out a large obsidian tower to the ocean floor.
I tried dropping the lava from the level immediately above the water and also two levels above the ocean. The result was the same:
A single tall spire of obsidian was created, and from there, the obsidian pancaked out into a circle, rarely extending beyond that one z-level. This meant I wouldn't be able to reach the ocean floor easily, this way.
Well, I took the next step of digging down into the disk I had created. I went down into that level, and channeled down, expecting the water pressure of the ocean all around me to swell up from the hole at my feet. Strangely, it did not. Well, from here, you could channel out the entire bottom of the construction, fill it with lava again, and repeat, all the way to the ocean floor. This would kind of suck, because you'd have to wait around for lava to dry up, or mix in more water, or something.. but I wanted to try it.
Well, this is where it gets weird. I accidentally channeled out the obsidian spire holding the whole thing up (I got to it via a bridge). Without the support, the whole thing fell down about 4 z levels and landed intact on the ocean floor:

This makes me wonder if I could somehow sink intact structures onto the ocean floor and make some good use out of them. One caveat is that the obsidian disk was not constructed- I understand constructions would have been destroyed.
For the interested, here was an earlier attempt- a bigger circle that connected with the land:

As you can see, there isn't much underneath that disk. It poured in just to the right of the three tile wide set of water tiles. That's where I feed the magma in.
Does anyone have more information about pouring magma into water in a multilevel situation?
