Common::Point Tot::RoomFileRegister::trajectories[9][30][5]

This is a preset matrix of trajectories from different areas of the game.action Each room is divided into a number of areas according to the screen grid [rejapantalla].action

A given coordinate in the game (x,y) is mapped into a grid position by dividing the x with factorx (8) and the y coordinate by factory (5). With each room being 320x140 this results in 40 horizontal divisions and 28 vertical divisions which matches the [rejapantalla] matrix.action

When obtaining the grid position a given (x,y) coordinate matches to, [rejapantalla] returns an area number.action

trayectorias then has a precalculated route from each possible combination of two areas in the game. pixel by pixel translation within the area is done by bresenham algorithm in the trajectory function.
