I wasn't sure where to post this, so I'll post it here.

So once again, I was experimenting with Dwarf Fortress to work on my wound editor. However, I kept coming across something odd. Sometimes, different parts would be coupled in with a part's layers.

I'm not good with explaining, so I'll give you an example.

The subject I was testing on (A fox) had it's upper body injured. However, in the layers, there was an entry for it's left lung, a completely different part. Yet the part was in the upper body's layer list.

Is this a bug or something? If not, why does this occur?

[MrRoboto75]

Shouldn't the lung be inside the upper torso somewhere?

[ChairmanPoo]

Maybe it's a teratoma?

Where else would the lung be, exactly?

DF uses parent/child relationships when dealing with bodyparts, especially in the case of internal organs. This is so that attacks on a major part can have consequences for the secondary parts, meaning that a spear strike to the chest can puncture the heart, and the heart cannot be targeted as a separate location (because it isn't, really... It's contained within the former).

So for something like teeth, the hierarchy goes (upper body) -> head -> face -> mouth -> "teeth" -> the individual teeth, such such as eye tooth, second molar and so on.

The upper body is in parenthesis because there's a slightly different relationship between major bodyparts and their connections than there is between a large part and its organs or minor pieces, but all bodyparts have a tree structure that is rooted in the upper body. This is what makes it possible to cut a head off of a body, rather than a body off of a head.


Also this is the wrong subforum, this is the general discussion for things that are not DF.

Its naught a tooma!

Ah, that explains it. I'm making a wound editor script, and that kind of screwed up the script, so I guess I'll have to rework the script.

Yeah, my bad. Next time I'll try and post in the DF General Discussion.

Hehehe, well, you'll know there's something really wrong with a script when it starts acting exactly as expected.

You can get a better feel for how bodies are put together by going into the Raws and looking at... uh... I think it's called BODY_STANDARD.txt? I don't have an installation of DF on this computer, so I can't check it at the moment. Note that, as with most of DF's structuring, it can be a little hard to read.

This will also probably be a better way of learning about how the game handles things like muscle/fat/skin layers, hair, and bones than I would be able to tell you, as I never around much with that.


I will, however, tell you about a lovely time back in my days as a fledgling modder for an earlier version of DF, when I tried to make a race of vampires. In an attempt to make the heart a truly critical location (it was entirely possible to survive massive heart injury in those days), I made the dumb mistake of giving it the [HEAD] tag, which causes a mob to die if the part gets damaged heavily.

This of course resulted in vampires with hearts featuring faces, eyes and teeth, and their bite attacks would be split 50/50 between the head making the attack and the heart leaping out of the chest to nibble someone. Nightmarish mental images were had.

I checked, and you're kind of right. It was called body_default.txt. I'll check it out and see what I can do.

Holy shit, that sounds both simultaneously terrifying yet awesome at the same time.

All right, I think I may have figured it out. The sub parts are being treated as layers to the regular injured part.
