Hey could someone look into how wounds work/get updated. I know there is some "calculated_XXX" flags but they did not seem to work when i removed brains from a dwarf (it should get him paralyzed?). I know that heart could be removed without any problems so maybe some info on how much bleeding should be correct for specific organ? Or just wound workings info would be appreciated.

Ah... sad: current dfhack has some bugs, one of them makes it so i can't track kills thus no money -.-

What specifically is the issue? Is it something that hasn't been fixed on the develop branch?

Would be really hard to do, considering that most tiles above a fort are solid, unrevealed rock.

That is easy: don't draw unrevealed tiles. The hard part is e.g. if it's dug out space. What then? You could make area around the cursor transparent but again...

Imho it needs some visual effect to make it useful.

There's build-windows.bat file in which you can just set path to dfhack and its version.

Ah, yep, thanks, got the vcxproj file set up with the paths and everything is good, I should have at least figured that out from the variables in the vxcproj file, sorry to trouble you.

Since you know way more about this than me, do you think it is possible (if I were to somehow gain the knowledge to do this on my own without bothering you) to render levels above you while having clickthrough to the current level?

The more I look at memory patching the more I realize that I have little hope of achieving this without being a huge pain the ass with more questions, but I'm willing to silently slog through it if it's possible.

It's really simple It could be done like this:

• You need to do something when game wants to render the game view, for that we use vmethod interposing: e.g. This gets called (instead) when fort-mode view is rendering
• Set window to where you want to render (e.g. in this case z+1)
• In that function you need to call "df-render-map" function, which mifki found.
• Read the screen and save it(?)
• Call original vmethod to perform "real" render
• do something with saved screen (e.g. somehow blend the tiles?)

Another example with rendering (in dfhack tree) here

Sorry if it's not twbt-like i've looked into that code quite long ago and can't quickly find relevant examples.

I remember in the old days people tried to get a fortress with 50+ years as moss would grow up everywhere...it is a thing yet, btw?

I was ecstatic when i noticed first tile of moss in one of my forts... But it was sooo long ago...
PTW btw epic story and fort.

I think I'm all setup to develop my cxxrandom plugin now, but I'm unsure how to import plugin functions into a lua script.
require('plugin.<name>') seems to be the correct syntax for importing, although the docs specify mkmodule('plugin.<name>') which did nothing but complain with errors.

The next step would be to give a shot at calling a function from a plugin. I can't seem to do that, so I'm guessing I'm either trying wrong or I imported the plugin incorrectly. I'm testing with the burrows plugin. Can somebody tell me how this is supposed to work?

I think it needs something like this: almost empty lua file to work. Don't know the exact reason why though...

I want to develop a dfhack plugin to export functions for random number generation.

The C++ random number distributions are looking quite appealing for a lua script I'm developing. There are some table entries I need to randomly select. I want to exhaust all selection options, randomly, in the fewest iterations necessary. So a std::uniform_int_distribution would be quite fitting for this task. Even creating a custom number distribution would be easier written in C++ over lua. A custom number distribution wherein: I create an array of my selection options (ie. a bunch of indices), then shuffle the array to a random order, and finally "generate" numbers by iterating through it.

I've looked over dfhack documentation, but there doesn't seem to be anything covering the creation of plugins. I've never worked with lua before last week, so I'm not even sure how exporting functions works.

• How can I get started?
• Do plugins require dfhack source files to integrate/build?
• Do I need to clone the entire repo? If so can anybody point me to a thread that covers getting setup? (preferrably in visual studio 2013-2017)
• Could I instead create my plugin without any of the dfhack source files, then drop it in? I feel this would be too convenient to be possible.

So there is a module that already has Mersenne twister implemented (before we could use c++XX) in a module . It could be extended to have more random stuff exposed to lua.

On the other hand module vs plugin (AFAIK) only difference is that modules are "baked in" into main library so other plugins/modules can easily use them.

• See: Compiling docs and Any files in here . There is also "skeleton plugin" but imho it's more complicated than it needs to be.
• Yes and no. Yes it needs for easiest build and integration. But there are ways to compile it without compiling whole dfhack. I think only mifki (of TWBT and other cool stuff) does that.
• Yes cloning entire repo is preferable. Currently we are in "new df version chaos" so pull-req are not being handled (afaik) and the compiling link should cover setup
• There are ways to do it... I did it by using online Continous Integration thing, but it does full dfhack compile (30min) so developing is slow and i'm using it only when i'm too lazy to update dfhack away from from my main pc.

As always: you can post your issues in dfhack thread or on irc channel
