Hello, I know I'm 3 years late, but I want to add info here about these files. Aura Kingdoms's map files consists of the .nif file(3d model of the whole map), dds textures for these models to use, and { fsm,fsmp,pgp }. fsm and fsmp are files with the description of the map's fisical models, they are used mainly for collision detection, if there's a stone model on the map these files should be able to tell this to the executable of AK and it will handle it as a model that can't be 'tresspassed', so it is considered a obstacle. Finally, pgp files are similar files which are responsible of taking fsm and fsmp data and creating a pathfinder mechanism, in 2D and 3D games a pathfinder is an algorithm which detects collisions in a path of a object and if it collides with something then it changes direction keeping it's final destination, so it can go from one point to another automatically. This is used when your character walks automatically through the map in the game.
