Nice find on the dwarf_race_index!  How did you get 0x015cbe9c ?  I was able to get the creature vector but got lost as to the next step.

I was having a look at http://code.google.com/p/dwarftherapist/source/browse/inc/dwarfraceindexsearchjob.h (god, that's an ugly filename), and it prints out potential values when searching for it through the memory scanner. I looked in run.log, and it had three or four potential matches that were all the same value, but got rejected for some reason or another. I just tried one of them (I may have had to correct the address, as it prints the absolute, not relative). Because I picked an address more-or-less at random, I suspect that I may just have stumbled upon a spot in code that happens to have that value, but may not be guaranteed to. I didn't really feel like searching through the entire memory of DF looking for 0x000001d1 (don't forget to convert to little-endian if you're using a memory inspection tool, if you're searching for it) and finding which one was the constant value.

Correcting the address:

look for this line in run.log:
2012-Feb-14 17:51:04.872 DEBUG   core   memory correction: "0x00ab0000" [../dwarftherapist/src/dfinstancewindows.cpp:259] (find_running_copy)

Subtract that value from any absolute address to get the relative address.

Is there a reason why using the BruteForce (raw output) section on say 0x0213be9c (dwarf_race_index) reveals garbage instead of strings?  Shouldn't the name & nick be viewable?  There is data there and it appears to be structured, but just not in a human readable format.

Keep in mind that that should be dumping the raw hex values from memory - 0x41424344 is equivalent to the character values 'ABCD' for instance. (forgive me if you know this already)

Additionally, the only data that should be at that pointer (if it's valid for dwarf_race_index) is a four-byte integer that's the index of "DWARF" within the list of races (as far as I understand). (e.g., if the list is { elf, elephant, goblin, dwarf, dog }, dwarf_race_index would be an int * pointing to the value 3)

Even in the creatures vector, if you're looking at the entry for a particular dwarf, there may be no human readable data available, or there may be. Consider the following two examples:

Example A:
Code: [Select]
struct dwarf {
    char firstName[16];
    char lastName[16];
}

Example B:
Code: [Select]
struct dwarf {
    char *firstName;
    char *lastName;
}

If we have a dwarf "Urist McUrist", and we want to represent him with these structures, he would have two very different representations in memory, looking at those structures specifically:

A:
Code: [Select]
55 72 69 73 74 00 00 00    00 00 00 00 00 00 00 00
4D 63 55 72 69 73 74 00    00 00 00 00 00 00 00 00

B:
Code: [Select]
AA BB AA BB CC DD CC DD

In the case of A, we have stored: "Urist\0\0\0\0\0\0\0\0\0\0\0" followed by "McUrist\0\0\0\0\0\0\0\0\0", whereas B is two pointers (0xAABBAABB and 0xCCDDCCDD) that are the addresses of "Urist" and "McUrist" in memory elsewhere.

Depending how a dwarf, or any creature, is implemented in DF's code, we could see either of these being the case. Especially since all of the names are from a preset library (and not procedurally generated, as far as I know), I could definitely see first name and last name both being pointers. Some others are index values (profession appears to be, race certainly is).

I believe that the custom nickname and profession names are also dynamically allocated, and thus you'll just see pointer values rather than the actual string values. At least, as far as I can tell, they are.

So I am about as oblivious as physically possible to the arcane workings of programming, do the posts in the last couple pages represent significant headway towards getting it working properly, or is it just dabbling in interesting notes?

Well, for reference, the total that I was able to get working in DT over about 4 hours of effort this afternoon (not knowing anything about the inner workings of DT or DF before about 1pm today):

- DT could read all of my dwarves, but only the following attributes
    - first name
    - nickname
    - custom profession name
    - gender

So, I'd say it leans somewhat towards "dabbling". I'd say DwarfEngineer's estimate of the end of the weekend at best still holds pretty strongly.

I'll be working on DT for 2012 as soon as I get a chance. It's highly likely that a number of the structures and offsets have changed, so I'm not optimistic that this will go quickly. Add on the fact that today is Valentine's day, and we're looking at end of the weekend as the earliest I'll have something.

Sorry there hasn't been much activity lately - I can't promise that I'll get to many features, but I'll do what I can to add support for the new version.

Welcome back! Take your time as I'm sure there will be at least one inevitable bug fix release to mess everything up again.

For what little help it is to DwarfEngineer, I've been mucking around with DT and a memory viewer all afternoon and have been able to figure out the following:

checksum is 0x4f391a33
creature_vector is 0x0179f728
dwarf_race_index seems to be 465/0x1d1 (value in the .ini I've used is 0x015cbe9c, but I don't quite understand how it's determined where this value specifically comes from)

With these, DT is able to read all of my dwarves and their first names or nicknames correctly, last names still show up as "Unknownunknown". Sex appears to read correctly (all of my dwarves are correct, at least), and custom professions are read properly too.

I haven't been able to figure out any other values, hopefully these can make it at least a bit easier.

I can confirm these values. I only had a few minutes to look so far, but at a minimum, some of the offsets have changed (as expected) but also, the way language and translation is handled appears to have changed. Take a look at the generic language raw.

Hah! You unlucky bastard! I must admit, I already surrendered after a wave of 20. One really realizes what he misses most when it's not available anymore :(
But I'm optimistic DwarfEngineer will not let us down, sadly that doesn't mean it will be fixed immediately :/

Wish I knew more about that stuff... I never bothered with memory reading - I just did coding. Now I regret I never got into that :(

I'm glad I didn't find out about DT until after playing for a while.

I can manage, but the faster you update it, the less pain I'll go through in the end!

Got a little bit more time to work on it, but I'm done for the night now.

So far:

In game_data.ini:
Code: [Select]
total_words_per_table = 2173
expected_dwarf_race = 465

With those settings, you can find the translation vectors as well:
Code: [Select]
[info]
checksum=0x4f391a33
version_name=v0.34.01 (graphics)

[addresses]
translation_vector=0x017e3638
language_vector=0x017e3618
creature_vector=0x0179f728
dwarf_race_index=0x015cbe9c
squad_vector=0x0000000

This will display your dorfs with last names. Next is finding the dwarf_offsets, etc.

I, too, found those values (once I found out about game_data.ini - still learning a lot about DT, heh).

I'm working on trying to figure out some of the offsets. From what I can tell, all of the following are definitely correct:

first_name
nick_name
last_name
custom_profession
race
sex

I'm looking to get current_job figured out, at least. profession and happiness would be nice, too.

I'll have to dig through the code to learn how the souls are structured to see if I can figure them out.

Edit: I got enabled labours working. Here's my v0.34.01_graphics.ini file, it will give what I would call a very basic level of actual functionality to DT - you can manage your dwarves' enabled labours, at least, though you cannot see their skill level, current job, or happiness

I'm praying you can get Therapist working sometime soon. I just got a wave of about 20 useless millitary dwarves and have now decided to wall myself off from the world and brutally murder any migrants that come.

It's strange that I'm more scared of migrants than I am of the terrifying creatures sitting in the bottom of my fortress.

I believe happiness is 0x082c and current job is 0x030c. I am working on some of the rest, I will keep posting what I find as well
