Not to ask people to write my game for me but...

        Assuming you have a coordinate plane with its origin at a given point. 
        Does anyone have any idea how you would get the x,y of points
        on that in terms of another coordinate plane skewed off the original
        one n number of degrees with its origin at a different point.  I'm
        writing a Wolfenstein/Ultima Underworld type game and need to know
        where points on the map are relative to the player given his current
        position and facing.  Thanks!
