   game space terrain and cells
  Hy.I would programming a real time robots strategy game , and i would organize a game space in cells,then i would calculate some things:1)area of view of the robots(the things that the robot view , can be enemy robot, explosions , guns on the floor ecc...)2)i would use a graph library for calculate the moviments of the robots , for this i use the graph path finder between 2 nodes.but how transform this 2 nodes in two coord in the cells in two coord at video in the game space terrain?3)calculate a bullet from this origin to the end if hit a robot.(also 2 coord begin to end)Thanks.   
  upup   ;  Everything you've said sounds reasonable.  What's the question?
