I'm doing a tactical game (X-Com / Fallout style) for fun. I've decided to use a hexagonal map, but I'm having a graphic problem.
My current map display is HUD-like, with only the border of the map cells displayed, without any texture. It's simple and allows for display of different types of information by varying the color of the border. For example, the "danger view mode" displays the borders with a color going from green (no damage possible) to red (prob of damage > 90%).
Now, it's a bit hard to differentiate the kind of tile the player is on. I could put a plain color (green is grass, pale blue is water...), but this is going to limit the possibilities. Thus, I would like to display a texture on my tiles. Since the maps are generated, I can not use a picture for the whole map with the HUD over.
So, my question is: does anyone know how can I generate the seamless hexagonal textures (algo or plugin)?
