| So, while I was scripting my Checkers board I had to incorporate an algorithm for arranging the pieces in a zig-zag pattern. As many of you already (but for those that don't, here you are), a checkers board is much like Quadrant-1 in a coordinate plane system. Which means in order to create this zig-zag effect, one has to construct as sequence like so: (0, 0), (1, 1), (2, 0), (3, 1), etc. And instead of using static, or hardcoded, values, I created a script that creates this sequence for me. Brace yourself, there is Trigonometry involved.
