I'm working on an iso RTS and I'm using the staggered approach to store my map data in an array. This means that each X co-ordinate represents 2 different X tiles, depending whether or not the Y co-ordinate is odd or even, in which case the tile is offset, shown below.
This works fine, however it does add an extra layer of complexity to every calculation, pathfinding, movement, etc.
I am curious, what are the alternatives? I require the whole map to be filled with tiles, so simply tilting a traditional square grid will not work, because many tills will have negative co-ordinates, and arrays do not have negative cells, shown below. Unless (0,0) is far, far off in the top left somewhere, but that leaves a huge amount of empty array cells and a seemingly unnecessary giant array. My maps are 256x512.
I'm open to all suggestions. Thank you for your time.
