Cave-Ins
« on: September 08, 2011, 08:09:15 am »

I'm preparing a cave-in to entertain some of my visitors.

1. Is a cave-in more likely to kill what's beneath it if it contains more z-levels of rock?

2. Does cave-in damage extend any distance horizontally? Can I safely put things right next to the cave-in zone?

Cave-ins always kill anything directly beneath them, all the time.  Doesn't matter how many Z-layers deep the cave-in is.

Cave-ins create large clouds of dust.  Objects and creatures near the cave-in, in the path of the dust can be thrown around and injured.  How bad that is may depend on how much material is falling and how far it falls.  I am not aware of any actual science that's been done along these lines.

Be careful that cave-in's with natural walls (and possibly constructed ones too, I'm not sure on that) will pass through any floors or staircases below them. As a result you can end up where this

Wait, you are confusing matters with that diagram. Noble bedrooms are an absolutely valid cave in target area.

Otherwise constructions like walls and floors will punch through floors, only difference to natural rock is that they will deconstruct once they hit a wall, constructed or otherwise.

Thanks, I'll be careful about what's underneath the cave-in.

I'm using a cave-in to speed along some digging. I'm digging around a giant space instead of straight through it. The mass of rock that will fall is about 60 z-levels high. What happens to all the rock in that mass? Will it all turn to stone as if I had mined it all? Or will some of it disintegrate?

Tons of people could answer your question better than I, but they aren't, so I thought I'd give it a stab, anyway.

I'm pretty sure, based on the replies I've received about caving in to move soil around, that no natural stone is converted to mined stone in a cave-in, and also none of it is destroyed or changes types. It just drops however far you dropped it, until it hits the ground and stops.

Not sure whether it drops tetris-style:
Code: [Select]
before:     after:
WWWWWW      WWWWWW
W I  W      W    W
W WW W      W    W
W W  W      W WW W
W    W      W W  W
WWWWWW      WWWWWW

or every-column-for-itself:

Code: [Select]
before:     after:
WWWWWW      WWWWWW
W I  W      W    W
W WW W      W    W
W W  W      W W  W
W    W      W WW W
WWWWWW      WWWWWW

Of course, natural floors left after mining are destroyed by cave-ins, so you could speed removal of natural floors that way, to avoid having to channel each square, and carefully avoid the danger of cave-ins, but I don' think it will get rid of unmined rock for you.

Spoiler: Grumbledwarfskin quote (click to show/hide)

It falls in the 'every column for itself' style.
