I am writing a program that needs to be able to access the map data from Dwarf Fortress. How is the data of the map tiles stored, and how can I access it? Basically, I want an array of all of the individual tiles in the area. How can I retrieve such information?

While I'm possibly the furthest possible from an expert on the subject, there's a memory access library which is easily your best bet for this sort of thing. It's not perfect yet, but it'll most likely do what you need.

Ah, no java libraries then? Hmm... the program has to be in java.

most of the DFhack stuff is C++ but any program (hint dwarf fortress) can make/use its own language if the creator is bold enough

 Hello and welcome to the forums!

 So yeah guys, this is basically a guy who wants to make a Dwarf Fortress to Minecraft map converter. Thus why Java is an issue. Then again, if it a program separate from either program and merely converts data then it need not be in the language of Minecraft.

Well, the language would be much less of an issue if I knew any C++.  I looked at the previously linked library and saw that it did exactly what I needed from this half of the program. Maybe I can just teach myself some very basic C++ so that I can utilize the aforementioned library to output to a text file, then read that in with the java program.

*Headdesk* I completely fail at learning how to use libraries in C++. The program I need is just about twenty lines, but I can't get it to run! I just want to go through all of the tiles and put their values in a text file, but I keep getting errors. ;-; Can anybody figure this out?

Code: [Select]

#include <iostream>
#include <fstream>
using namespace std;

#include <DFTypes.h>
#include <DFTileTypes.h>
#include <DFHackAPI.h>
#include <integers.h>

int main (void) {
uint32_t len, wid, hei;
DFHackAPI *pDF = CreateDFHackAPI("Memory.xml");
DFHackAPI &DF = *pDF;
if(!DF.Attach()) {
cerr << "DF not found" << endl;
return 1;
}

ofstream lWriter;
lWriter.open("Landmap.map", ios::trunc);

DF.InitMap();
DF.getSize(len, wid, hei);

for(uint32_t z = 0; z < hei; z++) {
for(uint32_t y = 0; y < wid; y++) {
for(uint32_t x = 0; x < len; x++) {
uint16_t* tile = 0;
DF.ReadTileTypes(x, y, z, tile);
lWriter << tile;
lWriter << " ";
}
lWriter << "\n";
}
lWriter << "===\n";
}

lWriter.close();
DF.Detach();
return 0;
}

This is the error I'm recieving:

I'm probably making some obvious amateur mistake here, but I can't figure it out.

Pretty sure something is linked incorrectly, if dfhack comes with a compiled library you'll need to make sure you link it (not an #include).

[VDOgamez]

I thought as much I just can't figure out how to link to a library in eclipse.
