What?

The contest... Its a Code Golf contest.

But there is no algorithm given?

But a task. Create something awesome and golf it down.
Most code golf challenges on codegolf.SE aren't about implementing an algorithm but to golf something as much down as possible.

what about including things like Anet, shadeC or other libraries that include code files? i assume that not allowed ?

I assume that you can include all data that is shipped with Gamestudio, but everything else would be "your submission". So, no. But that has to be confirmed by George.

Thank you for the kind words, Ratchet! I wanted to create a menu that's as simple as possible and can be used in other projects as well.

"what about including things like Anet, shadeC or other libraries that include code files?" HeelX is right: feel free to include any of the scripts that come with the default installation of Gamestudio in your project, but any other script must be your creation. You're the Ninja!

I'm sorry that I have to ask but I am still not sure what the contest is about.

So I can make anything I want?
Is it also possible to make something like a small game?

Yes and yes the only rules are the line count (semicolon count, sic!) and the filesize (5 KB); the guidelines I proposed are optional. If you can make a game, the better, I suppose

Ok thanks for the answer
(now I have to make a code which counts every ';' in a file )
