There is a Win32 version of Libnet though, so I will be working on this soon. The mini-map has been changed. Instead of seeing everything at all times, there is now a realistic radar system. Radars can be established at points on the map, or they can be associated with mobile units. Radar sweeps will uncover dark terrain, as well as update unit positions on the mini-map.
Individual radars can have different burst frequencies, rates of expansion, and ranges.
So, the idea will be to have as much radar coverage as possible. There is now a tile animation system that allows a contiguous block of tiles in a tileset to be rotated, providing an animation effect. The frill layer is simply a layer of tiles on the map that are drawn above the normal map tiles. The bases and flags are stored in the frill layer so that there can be terrain underneath them. The flags need this because they are transparent.
