Pressure + helpless goblins
« on: November 25, 2009, 02:32:02 am »
so, before  I get started on this project of minde, I need to know, will water that has 27 floors of pressure be able to sweep enemies off their feet and send them plunging down stream? if so, how far, on average will they be pushed before they can move again

Of course, why else would dwarves risk life and limb to retrive one sock during a full scale siege onslaught.
The depressing thing is that they quite often lose life and limb(s) in the process.

You might find this recent thread helpful. KenboCalrissian's first post in that thread is especially relevant.

More to the point, from what I understand, with that much pressure the goblins will be pushed about 1 tile before they're all in 7/7 water, which doesn't push anything. Fluids in DF do not work the way you think they do. Kanddak and some others have been working to improve the community's knowledge of fluid dynamics, but it's a difficult process.

Absolutely not. Don't make the mistake of thinking of DF water as if it's anything like water. You should read my thread that NecroRebel linked, which is also in my sig.

Pressure is not a quantity that you can measure as "27 floors". It's one of the rules for how water moves based on having a path through other 7/7 water to a space on a lower z-level, and it does not move objects or creatures at all under any circumstances. Creatures are only moved by water that is locally diffusing.

The wiki is notoriously inaccurate on subjects at the cutting edge, frequently reflecting passing memes, folklore, or the word on the street instead of true dwarven science.
