reprogramming, sort of

[futhamucka]

hey i dont know a huge amount about programming, but, want to edit a lot of aspects and graphics on openttd, has anyone got any ideas of how i could go about this?

P.S. I'm a mac user so please dont suggest anythng windows based, or i may have to kill you

Experiment! You might find OpenTTD a bit to complicated if you don't have much programming experience but there is only one way to be sure.

You should read: http://wiki.openttd.org/index.php/Compiling_on_Mac but to summarise and expand (now that we have openttd.xcode)

The first thing to do is get the right tools, you need:

1. Fink - http://fink.sourceforge.net/
2. Xcode and associated tools: http://developer.apple.com/tools/download/
3. SDL: after installing fink run: fink install sdl
4. libpng: after installing fink run: fink install libpng3
5. svn: fink install svn-client

Now you can build the game:

1. now, get the source by running: svn checkout svn://svn.openttd.org/trunk some_folder_name
2. go into some_folder_name and open openttd.xcode
3. Click build

OpenTTD should build and be ready to run!

thanks for that mate:) ill give it a go, also can you program in C on these programs?

plus, how easy dyou reckon it would be to smooth out some of the graphics, as i am a demon with photoshop

There's an edit button to edit your messages

OpenTTD is written in C. I presume xcode is a GUI for Mac OS X that makes the development process a bit easier.

A new graphics engine will be worked on in a future version. Some examples of new graphics can be found in the "OpenTTD Graphics" forum, perhaps have a look there?

you are right. It's way easier if you are not used to command line debugging

About encoding/decoding graphics files (grf files), you will need grfcodec. It do compile on mac, but unfortunately it's little endian hardcoded for file IO, so it will produce garbage data when reading files on big endian (like mac)
Hopefully this will be fixed eventually (I don't think I will have time to look at this soon ), but I will for sure make sure that a new graphics format will have endian safe tools

Yes.

That's exactly right. Apple's Xcode page has more info.

I'll upload some screenshots with this post.

Just checked out the code, but can't seem to find the "openttd.xcode" file in there. Any tips on how to properly setup XCode to import the OpenTTD codebase into?

There is no XCode project file in the code base. But you can simply from a terminal compile it: ./configure && make
Checkout our wiki for more details on how to compile.

I saw somewhere that people were doing code editing and debugging via XCode, so I was trying to find out what is the proper way to configure the XCode project to import the codebase, get the code completion, etc.

I used to just open the openttd '/src' folder in xcode. I did try configuring an xcode project once, but it didn't seem worth it. I just use TextWrangler now instead. Compile with make.
