v0.31 Talk:Obsidian

It looks like obsidian will still be used for constructing items out of stone- I'm staring at some obsidian mechanisms right now. I haven't checked yet if it works for items made at a mason's workshop. --Vaniver 21:24, 11 April 2010 (UTC)

Actually, what happens is that obsidian is just not being listed in the "economic stone" menu. If it is a layer in your starting location, it will be allowed for construction (green), if it is not a layer, it won't be allowed (red). Since it is not listed, you cannot switch between these two states. To allow obsidian to be listed, you have to remove its "max edge" tag from the raws. You can add it back after switching, and the game will remember its "cannot use" status. 157.82.24.21 08:01, 16 April 2010 (UTC)

Confirmed. I'm using mayday edition v0.31.08, and it worked like you described (thanks!). To clarify, the tag is [MAX_EDGE:20000] under [INORGANIC:OBSIDIAN] in the file data\save\regionX\raw\objects\inorganic_stone_layer.txt --83.183.240.185 18:24, 27 July 2010 (UTC)

im confuzed. whn i make rock short swords they show up as cedar short sword ect not obsidian short sword. it this correct? --gareth 10:26 08 June 2010

v0.31.06 - Also seeing obsidian swords being created as random-wood swords. --awilson

I was not able to make obsidian by dumping a bucket full of water onto magma. Instead I ended up with a 1/7 water tile. Not even any steam.--Passive Fist 12:47, 3 July 2010 (UTC)

Since I was confused by this: I was able to make obsidian by dumping a bucket full of water on lava. I had to have one extra z-level of open space between the pond zone and the lava though. Otherwise it would just produce steam.^v0.31.25 --SGdYy409Ls 06:35, 16 October 2011 (UTC)

So if I make an obsidian short sword, does it deal damage like a regular wooden sword or like the 40D obsidian short swords?

As obsidian. The bug is fixed as of v.x.16, btw.

The sword one may be, but the economic stone listing one isn't. Gaah, I wanted a road paved with obsidian blocks.

Magma-safe items

I've gone ahead and edited the part about "all items being destroyed" in a water+magma reaction tile. Magma-safe items are not destroyed, but are entombed within the tile. If the tile is mined, the items will re-appear. This is quite easy to test. --Heavenfall

This could be quite useful for traps. --GaxkangtheUnbound

I actually just entombed a group of caged goblin invaders in my obsidian farm and I was surprised to find a copper cage and most of the goblins copper items when I mined out the following obsidian. AS I'm running an unmodified DF I'm changing the text to show that not even all magma un-safe items are destroyed. --Egodeus 14:53, 29 May 2011 (UTC)

I've observed that copper and bronze usually survives brief magma-baths, but silver almost always melts if left in too long. It might be due to other material properties. --Quietust 16:00, 29 May 2011 (UTC)

Bones can survive entombing, especially if you flood the creatures with water and then cover them with magma, not the other way. --Someone-else 16:37, 29 May 2011 (UTC)

I'll consider it verified and remove the verify tag. --Egodeus 13:56, 1 July 2011 (UTC)

effect on outside

If you cast obsidian outside for living space rather than stone then does the tile become inside and/or subterranean again since there's a "natural wall" above it? Cpad 07:17, 24 May 2011 (UTC)

Melting obsidian

I was in the middle of making a flooding trap through an obsidian layer. I suddenly get the message that a section of the cavern has collapsed. I also see a combat report, which was the first time on that fortress. It mentioned the dwarf caught in the collapsing being caught in BOILING MAGMA. Eight times. Is this normal behaviour with obsidian, or a bug? -121.44.251.31 07:35, 27 May 2011 (UTC)

It's a known bug. The game mistakenly labels the dust cloud generated by a cave-in as "boiling magma". (The rock dust gets labeled as rock gas. And, technically, the material is roughly equivalent to magma mist, minus the toxicity and lethally hot temperature. Meaning, it's rock in a form that is neither liquid nor solid.) To wit:

Boiling Magma where there is none

Cave-in dust is sometimes mistakenly labeled using the material's gas state rather than its solid powder state (i.e. it's equivalent to it saying "steam" instead of "snow") - thus, while it may have said "boiling magma", it actually meant "stone dust".

The Bowyer has been caught in a cloud of boiling magma!

Don't worry, it's a known bug. The bowyer was hit by rock dust from the cave-in, but the dust uses the "gas" name of rock rather than the "powder" name. It isn't actually hot, but it can fling them through the air with some force.

Testing Arena

It seems impossible to outfit creatures with obsidian weapons in the object testing arena. Bug?
