Fluid related questions
« on: August 01, 2010, 05:53:13 am »

I was wondering...

1) Can you flush invaders off map with a stream powerful enough? I'm talking gigantic reservoir, with lots of floodgates opening simultaneously. Magma is too much of a pain to pump up anyway...

2) Are tame carp offspring still bugged and tagged as hostile, and do they still go batshit insane when caravans arrive?

3) How far can a dwarf be flinged by a stream? I'm envisioning a "rocket slime"-ish megaproject, with goblin prisoners and my military in separate giant "tanks", firing various stuff and themselves at the ennemy.

Faisible?

1) Sorry, but no. Beings either choose to leave a map of their own accord, or not at all.
2) When was this?
3) They can't be flung by water at all. Momentum isn't really well modelled (yet); the only thing that comes close is bodyparts/bodies being hammered/hurled by various warhammers, maces, axes and so forth.

Christ, are you dwarves or are you elves? If you think Hell has too many demons, then you kill them till the population reaches an acceptable number.

You COULD line up your fort so that the hammerer shoots dwarves out of a cannon, but usually that doesn't have as much of an effect on the invasion.

Too bad :(.

Alas, this is not fast-paced enough.

1.) I'm trying to get exactly the same thing to work. It should be possible, but isn't easy; you need to work around limitations of the game:The pressure simulation is more concerned with how much water ends up where than what it does on the way. Teleporting fluid (caused by pumps or, for water, gravity) doesn't affect objects in the tiles it passes through. As such, you'd maximise flow/depth gradients rather than volume of water moved; probably involving a water source hooked up to a repeater and a fairly elaborate drainage system.

2.) Not a concern any more.

3.) Momentum is only accounted for in very specific situations; what you describe isn't possible to my knowledge.

I haven't see the specific problem you mentioned, and more generally terrified screams of 'oh, carp!' seem to be a thing of the past.

I modified the carps as tameable in the raws, then put some cage traps in a corridor near a river turn, tied a kitten, flooded the corridor with filtered water, then opened it to carps, then drained it, then tamed the carps, then dumped the carps in my moat.
That created many goblin chunks, until they made babies. The babies were "Hostile", and ignored the dwarves but drowned/salsaified two caravans and a diplomat. Then a human siege came and shot them all.
I heard that the same thing happened to someone else with cave crocs.

Maybe you could use the water to push them off a cliff or into a pit? Send them to visit the GCS for a chat and tea.

This doesn't have the appeal of "GET OFF MY MAP".
