I have recently been playing around with the XNA framework to get a grasp at how to develop games for the XBOX 360. It is great fun, but quite different from the development I usually do. So far, I have a game engine foundation, which lets me create generate missions from image/text file tuples, where the image determines the mission’s board and the text file describes the mission, emenies, goals etc.
This setup makes it easy to quickly develop a large amount of missions, that can be divided into multiple campaigns. By making the base model solid, new missions will be more like content management than programming.
When my game engine imports a mission map image, it generates a grid of walkable and unwalkable tiles, of which the board consists. I will write more about these tiles and how to handle them in a future blog post.
The next step is now to be able to find the shortest patj from a tile to another. I found this great tutorial and will use it to implement the A* algorithm, which hopefully will take care of this for me:
