Question

Right now I have this:

for (int i = 0; i < level.contentSize.width/level.tileSize.width; i ++){
    tile = [levelLayer tileAt:ccp(i,17)];
    if (CGRectIntersectsRect(ball.boundingBox, tile.boundingBox)) {
        NSLog(@"hit");
    }
}

What I need to have is two variables (right now I have one- i) so that I can check all tiles in all x and y values. So the tile = [levelLayer tileAt:ccp(i,j)]; <—would look like that.

You can try using inner for-loop with another loop variable j iterating through all possible values. Something like:

for (int i = 0; i < level.contentSize.width/level.tileSize.width; i ++)
    for (int j = 0; j < level.contentSize.height/level.tileSize.height; j ++){

        tile = [levelLayer tileAt:ccp(i,j)];
        if (CGRectIntersectsRect(ball.boundingBox, tile.boundingBox)) {
            NSLog(@"hit");
        }
}
