Is this still valid? I recall that only truly disconnected areas cave in these days...
Yeah, this is what I've heard. I'm digging out a bunch of greater than 7x7 rooms now so we'll find out shortly. --Karlito 00:26, 30 October 2007 (EDT)
- I've dug out some big rooms (10x10 I think is the biggest so far) and not had a cave-in for a season or so. I'm thinking it only does it on disconnects. makes it ALOT easier to plan your fort out. --BurnedToast 00:33, 30 October 2007 (EDT)
- No kidding. What are the chances of accidentally completely disconnecting an area? I think that Toady One is going to continue to tweak the cave-in circumstances, though, so some things that don't cave in now may in later versions. --Peristarkawan 12:56, 30 October 2007 (EDT)
- Sorry, but I don't understand what a disconnected area is. Could you try to explain? sinoth 12:50, 30 October 2007 (EDT)
- A disconnected section doesn't connect to the rest of the map. As far as I know, that means it checks above, below, north, south, east, and west of a block of stone for connecting blocks, and continues checking through them to make sure the section isn't isolated. Toady mentioned something along the lines of it only checking for disconnects around the area you are mining. If the section is isolated, each block of the disconnected section will fall straight down. That's the general idea, I believe, and such disconnects are not easy to create. --Janus 13:12, 30 October 2007 (EDT)
- I can easily see how to create an isolated support, but how would you create an isolated room? The dwarves would have to get there somehow... Also, wouldn't an isolated room (with nothing on any side of it, including above) be less likely to collapse because there's nothing nearby to collapse into it? --Bobson 13:49, 30 October 2007 (EDT)
- 1. Build a box with constructed walls from the ground.
- 2. Remove the construction connecting it to the ground.
- Also, an isolated room, would have to collapse, unless we've got anti-gravity-field-generators. --Savok 14:59, 2 November 2007 (EDT)
- I've mined out several levels underground. Then I dug channels (carefully) around the edge of the top layer. Once the last channel section was finished... bam! Cave-in. Only, it didn't stop at the first level below. It kept going to the last level dug out, taking with it all the loose debris. If there are any BUILDINGS in the region that collapsed, they will break apart. --AzureLightning 14:04, 30 October 2007 (EDT)
"Don't pay any attention to the information below this line! It is simply a placeholder!" - Why have it there if doesnt need to be? Take it away and readd when something worthwhile is to be said. --Mizipzor 17:51, 31 October 2007 (EDT)
When building my underground farms with light access I had alot of collapses but once the room was finished they ceased. There 8 by 8 and three floors down with open air access. I think a collapse happens if you have a room greater the 7x7 horizontally and more than 3 vertically. From what I've observed it seems like it only checks for a collapse everytime a square is dug. --Lucid 20:57, 31 October 2007 (EDT)
