Documentation for the Rasterizer module.
Example Uses an L{SCA_MouseSensor}, and two L{KX_ObjectActuator}s to implement MouseLook::
# 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()
# Set the amount of motion: X is applied in world coordinates...
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)
# Centre the mouse
Rasterizer.setMousePosition(Rasterizer.getWindowWidth()/2, Rasterizer.getWindowHeight()/2)

def makeScreenshot(filename):

Writes a screenshot to the given filename.

The standalone player saves .png files. It does not support colour space conversion

When run from Blender, makeScreenshot supports Iris, IrisZ, TGA, Raw TGA, PNG, HamX, and Jpeg.
Gamma, Colourspace conversion and Jpeg compression are taken from the Render settings panels.
