The Game: progress (3)

Another strange turn on the road of game development. I was thinking about hex grid and looking for possible ways to display it. There are several problems about it:
- cell/tile notation, or basically the system of coordinates
- conversion between the internal system of coordinates and the cartesian coordinates of the screen
- adjacency of the fifth and sixth cells
I came across a number of useful resources about hex coordinates:
- Amit’s Game Programming
- PlayTechs: Programming for fun
- Ron’s Brain: Hex map in Javascript
- … and many others
The main problem is that almost all resources look at hex grids with adjacent upper and lower cell, while I want a grid with adjacent cells located to the right and to the left. So I will learn conversion between coordinates and the math behind it, by implementing the same examples to “my” grid orientation.
To start with, I took Tim Holt’s hex map example, read about a game called Lights Out, and implemented a hex version of it in JavaScript and plain HTML, using no PHP for grid rendering (in contrast to Tim’s example). The result is here. It has a fairly easy solution, the design is wanting and the code is surely buggy, but it’s fully functional and playable.
