I have been playing around with coordinate systems for a simple RPG. What I'm trying to do is to spit out a series of coordinates, starting from a center point (0,0) & circling outwards.

I have come up with this. But there's a lot of redundancy in the code. I know there is a simpler way to do this. Please bretheren, I ask your advice.

#!E:\perl\bin\perl.exe

$max_range = 3;

for $range(0..$max_range) {

        $y = $range;

        for $x(-$range..$range) {
                print "$x,$y \n";
        }

        $x = $range;
        for $y(reverse(-$range..$range)) {
                print "$x,$y \n";
        }

        $y = -($range);
        for $x(reverse(-$range..$range)) {
                print "$x,$y \n";
        }

        $x = -$range;
        for $y(-$range..$range) {
                print "$x,$y \n";
        }

}

Wait! This isn't a Parachute, this is a Backpack!
