I got an array which holds nodes on a grid. To find out where in the array I want to put each node, so I easily can find them again by giving X/Y, I do this:
index = (y * totalSize + x);
This has been working nice so far, but I'm at a complete loss on how to reverse this calculation if I got the node index and want to know what position that would be on the grid. Any hints for a tired brain?
