So yeah, this is doing my nut in and I can't figure out why.

I have a file that has tile information stored in the format of integers (1 = wall, 0 = empty etc etc)

Basically here it is, this basically creates 1x1 static box2d bodies that represent walls, however it is mirrored on the x axis and y axis. If I put a 1 at the left of my text file it actually creates the wall at the opposite side...

It's bugging me big time, any ideas? Cheats etc lol.

So you are probably reading it from the wrong side.
x=0->max   x=max-(0->max)

Yeah I see it now, acting weird though. It works for the iteration of the x axis but not the y.

for (int x = width - 1; x > 0; x--) {
            // Read the entire line
            String line = reader.readLine();
            // Avoid null pointer when reading end of file
            if (line == null || line.isEmpty()) {
               Gdx.app.log("Info",
                     "Reached end of file, level loading complete");
            } else {

               // Split the values
               String[] values = line.split(",");
               for (int y = height - 1; y > 0; y--) {
                  // Get each value and parse it to an integer at col x
                  // and row y
                  cells[x][y] = Integer.parseInt(values[y]); // Throws exception here first iteration


Seems to freak out when inside the inner loop, i'll figure it out. Had problems doing it earlier, just needs practice.

Possibly you have to read your file bottom-to-top to make it readable for yourself, but normally you could always read

int x =0; x < width; x++

I did get it working but decided to go with a different approach.

I just read the pixel values from an image into an array and use a witch statement depending on the hex color value, this means I can sit and draw levels in photoshop or something, hella lot easier on the eyes.
