Module Rasterizer

Documentation for the Rasterizer module.

       # To use a mouse movement sensor "Mouse" and a 
       # motion actuator to mouse look:
       import Rasterizer
       import GameLogic

       # SCALE sets the speed of motion
       SCALE=[1, 0.5]
       
       co = GameLogic.getCurrentController()
       obj = co.getOwner()
       mouse = co.getSensor("Mouse")
       lmotion = co.getActuator("LMove")
       wmotion = co.getActuator("WMove")
       
       # Transform the mouse coordinates to see how far the mouse has moved.
       def mousePos():
               x = (Rasterizer.getWindowWidth()/2 - mouse.getXPosition())*SCALE[0]
               y = (Rasterizer.getWindowHeight()/2 - mouse.getYPosition())*SCALE[1]
               return (x, y)
       
       pos = mousePos()

       lmotion.setTorque(0.0, 0.0, pos[0], False)
       # ...Y is applied in local coordinates
       wmotion.setTorque(-pos[1], 0.0, 0.0, True)
       
       # Activate both actuators
       GameLogic.addActiveActuator(lmotion, True)
       GameLogic.addActiveActuator(wmotion, True)
