I get the errors:

201 invalid types `int[int]' for array subscript

201At global scope:

205 `int firstroom' redeclared as different kind of symbol

[NUj6URfi]

Bump.

[Zhuge]

Line 201: firstroom() returns a integer, yet you are trying to index into it with [].

Line 205: Erm, what is this supposed to be? Some kind of function declaration...?

[NUj6URfi]

Line 205 is a function. How do I fix 201?

[Dy7SLyTq]

the parameter for it is really really wrong

[NUj6URfi]

And????

[Dy7SLyTq]

fix it. you are honestly telling me you cant figure out what is wrong with the functions parameter?

[N36fSL3A]

Why the hell are you using a multidimensional array for maps?

I think I already explained how difficult that is to manage. I have some code from an old RPG you can look at. It's made in SDL.

[Dy7SLyTq]

Why the hell are you using a multidimensional array for maps?

what are you talking about? hes only using vector arrays

[N36fSL3A]

[Dy7SLyTq]

thats not a multidemensional array. thats a vector array

edit: can i call it a vector array, because doesnt it represent a mathematical vector?

[NUj6URfi]

Sure. I know how to pass and return variables just not arrays. Also my book didn't say anything. It's not just an array but

myTileset[ firstroom()[ (b*MAPTOTAL_HEIGHT) + x ] ]

Well, since it's a pokemon game, I'm guessing you don't need layers. My map files for an old project will be pmed to you.

[NUj6URfi]

I need a zip

[N36fSL3A]

Why don't you download winwar

[Dy7SLyTq]

*winrar and i wouldnt get that. i dont really like it. i would personally use 7zip, but if your on linux, there is a builtin unpackager. just fire up the terminal navigate to the directory where the file is and just tar file_name

[NUj6URfi]

I don't want to download a rar thing.

[N36fSL3A]

Why not?

You'll need winwar to download many files. It's pretty lightweight.
