A quite difficult problem...

[CMaster2003]

I have 3 questions to begin with:

1. After I have created a unit(hopefully I'll manage) what should I do so that the game knows about it(including AI) and actually to be able to play with that unit?

2. Where can I modify the "global warming" occurence chance?

3. Where can I download an ANSI C compiler, the gmake program and everything else that I need to compile the game? (I know this sounds stupid but I'm hoping that there is a site which contains all of this stuff... for free ).

[Per]

1. If the unit is in the ruleset, the the game and the AI will know about it and use it.

2. Don't know. I think this is hard-coded in the source code.

3. Depends on your platform. If you are a Windows user, then you should try http://www.cygwin.com/ - press 'Setup' and choose to install everything. Compiling on Windows is hard. If you are a Linux user, then in all likelihood your system already has all the tools you need :-)

[Thue]

2. You can do it by editing the default value of game.warminglevel in common/game.c, and then recompiling .

Thanks for your help! I owe you one...

Yup, it's there (I love browsing the source)

Yeah, I found it myself, but thanks anyway for your effort
Anyhow, I think it's better to make the AI manage pollution better rather than changing the game.globalwarming variable...

I had no doubt you already found it yourself. But I was adressing the casual reader here.

My statement is meant to show of the fun things things that FC offers to the average public/forumgoer.reader/lurker. You can browse the source directly at the website! Is this relevant to programmers or someone who is already into Freeciv? The answer is no.

So nothing new for coders and FC players. True, but it's also important for others (who are not into FC) to know that these features exist . You have to show your stuff if you want people to get interested.
