@julesv, yup. You can create as many TMX files as you like.

@neophit I was thinking of tiles, would ti work if I had lots of them for lots of different puzzles?
@randomtruth Thank you :D

@randomtruth: thats a very kind gesture. It might be better to use the PM mechanism rather than publishing your email on a public forum.

Have you looked at Tiled? TMX Maps are supported in cocos2d.

It seems like you are having some problems with the basics of objective-c send me an email @ skylersaleh@gmail.com and ill give you some help.

To tell you the truth I am genuinely confused. I'm 14 and although I have quite a lot of experience with programming in general (Python) I'm finding cocos2D really hard right now :/ I get the main concepts, but it's just where to place my code etc.

Would I remove the nsarray and just declare the int[x][y] instead? Do I actually need to declare anything in the header file?

You are definitely on the right track. I would create something like this.

const int MaxX = 10; //amount of X tiles
const int MaxY = 15; //amount of Y tiles
int boards[MaxX][MaxY];

You can manipulate boards[xnumber][ynumber] the exact same way you would handle an integer.
To go through the entire grid you would need to set up an iterator.

int x = 0;// reset variable
while(x<MaxX)
{
int y = 0; // reset variable
while(y<MaxY)
{
int aNumber = boards[x][y]; // gets number at (x,y)
++y;
}
++x;
}

Also if you want to you could make an array of CCSprites by replacing int boards[MaxX][MaxY] with CCSprite * boards[MaxX][MaxY]
then this iterator will give you a sprite instead of an integer.

Hello! I'm implementing this (http://www.puzzle-light-up.com/) game. I've started by making a 120x120 grid placed in centre of my screen. I also created a 2D array. My idea was to make seperate files with lots of puzzles. In the files there would be a notation like this:
0=empty/unlit
1 = lit
2=filled in block with nothing in it
3=filled in block with 1 in it etc.
6 = has light bulb in it

Could you teach me a way to fill this 2D array with a seperate/external file. I was thinking of a loop which fills board[x][y]. Also, if you have any tips on how to represent the array visually after it's loaded please tell me.

Thank you :D
