I've been trying to learn how to highlight a hexagon when the cursor is over a hexagonal tile. I've read several articles that explain it using a "mouse map" texture image that helps to determine if the cursor/mouse is within a hexagon on a tile map. However, I can't seem to get it to work. I originally tried using the tutorial from Kurt Jaeger's xna resources but its mainly for isometric tiles. I then found an explaination on gamedev.net but my puny brain can't seem to comprehend it. If someone could help explain this concept of using a "mouse map" or maybe an easier method would be great. Unfortunately, it won't let me upload my solution. If you need to see my project, let me know a way of posting it. Thanks.
I forgot to mention, this is in XNA 4.0
