Example on how to implement a pixel-to-hexagon-map-location algorithm.

John Eriksson
Using hexagon based maps is not as easy as using square maps. Mostly because it takes more effort to translate pixel locations (like mouse clicks) to map locations. When I search this issue on the net I found a really nice article explaining a technique to solve this matter with mathematics. But I wanted to have a pixel-perfect pixel-to-map algorithm so I used the article as a base and implemented a way to solve this.

Based on the assumption that if I needed this then probably someone else need it I wrote this little example to show how a pixel-to-hexagon-map can be implemented in python/pygame.

Example Instructions

When you move around the mouse pointer the application will translate the mouse location to a hexagon map location and show this with a yellow hexagon.

    The way shown here is not good enough, since it is based on predefined matrix of hexes. I found a better method, which is more universal and works for every hex tile size. Mail me if you wish an example
