a careful inspection of z / stones reveals that obsidian is not even listed.
2010-04-02 01:39   
thats right. i manually forbid all of it from the z->stocks screen. easy enough work around, but it would be nice if it worked (as i imagine) as it was intended.
2010-04-03 12:52   
Probably related to 0000256. Obsidian is not being used to make "rock swords", thus it's not an economic stone, thus it isn't in the Stones screen.
2010-04-08 07:18   
I was trying to enable obsidian and couldn't mark it as a non economic stone. I noticed that Raw Adamantine has the property Sharp blades. It looks like obsidian and Raw adamantine have gotten squashed together somehow.

Actually most ores now have the ability to make sharp blades.
And yes, obsidian is not listed in the Stones menu. Possibly related to [LAVA] tag? Removing the tag from a previous save doesn't make it show up, so probably not, but that's about all I can see from the raw files that makes it different to other stones, bar the value.

2010-04-16 00:44   
I have found out that this is related to the [MAX EDGE] tag. Removing the [MAX EDGE] from obsidian makes it show up in the economic stone menu again. It also makes it no longer able to make swords (as expected)

By the same token, adding a [MAX EDGE] tag to another stone with a very high value makes it able to make swords (as expected) and removes it from the economic menu (try it with a normal, useless stone).

ON THE OTHER HAND, if you take a MAX EDGE stone, and add the [FLUX] tag to it, it starts to appear again on the menu. (and becomes flux material).

My guess is that the logic that hides/shows things in the economic menu is inversed for "sharp blade" stones. So all the common stones which are NOT able to be sharp blades appear on the menu, and obsidian, which is "sharp blade"-able and nothing else gets hidden.

Even if the stone is not being displayed on the economics menu, its green/red status is remembered by the game. So if you want to use obsidian for constructions, you can remove the "max edge" tag from obsidian in the raws (material_stone_layer.txt), load your game - obsidian will be shown as red in your economic stone menu. Turn it to green. Then save your game, and return the "max edge" tag to obsidian. When you return to your game, you won't be able to see obsidian anymore, but the game will remember that you gave permission for the use of obsidian.

awesome workaround!

Reminder sent to: aepurniet, caranha, DoctorZuber, Shurhaian

Is this bug still present in 0.31.25, or was it fixed along with related bug 0000256?

Obsidian is still not shown on the economics "stone" menu. v.25

I got this bug in the newest version (31.25)
2011-04-08 15:25   
There's another work around that doesn't require either removing the max_edge permenantly or save/loading each time you want to toggle its status.

Create a custom reaction of some sort that uses obsidian as a reagent and that seems to make it appear normally.

For example, I have:
[NAME:make obsidian mechanism]
And every thing works fine

The Stones screen appears to exclude all inorganic materials whose only "special" characteristic is "Sharp blades", i.e. having MAX_EDGE >= 10000.

The following binary patch disables this check in Win32 v0.31.25 SDL:
0x2AD5F4: 33 -> 00

As a side effect, this causes all other metals to start showing up in the list.

Alternatively, the following binary patch switches the condition around (from "MAX_EDGE >= 10000" to "MAX_EDGE < 10000") and causes the Stone screen to exclude materials which cannot be used for "Sharp blades" (or anything else), effectively making the Stones screen behave the same way as it did back in 40d (and not listing "mundane" stones), which is probably how it was supposed to work all along:
0x2AD5F3: 7D -> 7C

2012-02-01 11:40   
Binary patch for version 0.31.25 Linux: (untested)
4A7F52 : C5 FB FF FF -> 00 00 00 00 (display all stones)
4A7F51 : 8F -> 8E (show obsidian but hide all "mundane" stones)

This should be sorted now. Thanks Quietust!
