Dune 2 Legacy source code?

XTF · August 13, 2002

TonyD, do you plan to release the source code? Others might be able to spot bugs, improve performance or add cool features.

TonyD · August 13, 2002

hmm I am considering it, Ill be able to host it on sourceforge too, Ill have a few days to think about it........

stefanhendriks · August 13, 2002

actually my experience is, even if you use any license like thingy , or sourceforge or whatever. Your source will always be ripped and claimed as someone elses work. I think its hard to fight it. Thats why my point of view is with several projects "I give it, and i dont give a damn if you use my code and claim as if its yours".

Only do this if you code for your own fun and you REALLY dont give a damn ;)

XTF · August 14, 2002

That's your experience with CS bots. I think the chance of that happening is less likely for a Dune 2 game.

BTW, the XCC source code is also available on SF: http://sourceforge.net/projects/xccu/

One idea is when you release the sourcecode, you let one part out or something. Just so ppl not good at programming wont claim it as their own and use it ;)

stefanhendriks · August 14, 2002

indeed that was my experience with bot programming. I saw every bot who was releasing their source being ripped. Thats why i never will release the code of mine.

It wont happen that fast with Dune 2 Legacy ofcourse, but then again, its about the principle. You have to face it that there will be people ripping off code...

TonyD · August 14, 2002

some good points raised here.

There are some parts of my code that I am quite proud of and wouldn't want any one ripping, but most of it I wouldn't really care what any one does with it... But if I released only part, how much use is a portion of the code, people wouldn't be able to compile it, let alone help with the game development.

I am also not quite sure what I want to do with it as well, I have plans to add support for 3d objects and terrain much like newer similar games do, such as warcraft3, emperor and such, also networking, and good ai.

Decisions, decisions.....

BTW theres a patch out, which changes only a few significant things, although I have upped it to 0.15 because it seems very stable.

Hey Olaf,

theres a program on this page with source that manages to extract the icon files from the icon.icn file. If you adjust the palette file in the same way your mixer does for the app, some of the tiles come out looking almost correct, however I can't make sense of the src, it seems not to match the app. Do you think this could be any help for you in decoding the icn format?

well.. cyborg... it then u kloose the pint

only good programmers that can finish the poject will steal... other just look and try and be happy when their modifications work...

Tony D:

You wrote about 3D program...

Do you want any models for your 3D program? ;D

This hasnt much to do with open source projects...

TonyD · August 15, 2002

yep that would be great, but don't expect any results for quite a looong time, Im gonna get this finished before I extend it to support 3d stuff

XTF · August 15, 2002

What's your goal? My goal for XCC was to develop utilities so I could edit the game. That goal was met. Whether somebody else would release other utilities didn't matter.

If you use Visual C++ 6 too, you could release OBJs instead of Cs to protect part of the source code.

Why do you think the source doesn't match the EXE? I guess it's a great help, but I can't find my Dune 2 files to test it now.

stefanhendriks · August 15, 2002

i sent Olaf an IM about this btw ;)

the source code of that icon extractor is not compiling to well on my MSVC6. It gives some warnings, but then it also does NOT create any good bmp's anymore. They are not even read as a good BMP format. I guess you really need a C compiler. (an older one?, other one? i dunno).

I thought u may have, but wanted to be sure he knew about it....

Anyways, I think the code is wrong because I had a look at some of the offset definitions, and some seem to be way beyond the length of the icon.icn file - it seems something is deffinately wrong with this unless I am not understanding the code in it correctly.

iconconv.c(34) : warning C4013: 'exit' undefined; assuming extern returning int

iconconv.c(46) : warning C4013: 'writebmp' undefined; assuming extern returning int

iconconv.c(54) : warning C4101: 'z' : unreferenced local variable

That's 'normal'. You probably need to add "#pragma pack(push, 1)" at the top.

I think you misunderstood my last post Olaf.

The code did compile, yes, with these errors, indeed. But, the output of the program was totally garbage. No program would read the bmp files at all.

thats all what i meant ;)

TonyD · August 16, 2002

see this:

#define INDEXOFFS 0xd248

the file is only 0xCE9D bytes long!

BTW there is now a dedicated forum on my dune page, if anyone cares.

XTF · August 16, 2002

It's 0xd3d7 (54231) bytes long.

I know. And I fixed both the warnings and the garbarge creation.

TonyD · August 16, 2002

Am I do something really stupid, both windows and my hex editor show it as being only 52,893 (0xCE9D) bytes long. Pehaps somehow I have gotten a wrong version or something,

does your code create the tiles looking correctly as they should as well with your version of the icn file?

I have version 1.07 of dune2, perhaps there is a difference.

Ah ic yes, I had a look and it seems this has been the reason why I couldn't do this all along, stupid me, thanks Olaf.

XTF · August 16, 2002

I downloaded SuperDune from this site and used that version. Yes, they look fine. Should I upload the BMPs?

Did you use the code I posted?
