Split Screen Python script help

I’m working on a split screen game in blender. I got my hands on a real sketchy script for multiplayer . Can anybody possibly with some python experience give me a hand?:yes:

Right now I’m currently having problems with the
own = gamelogic.controller().owner.()

there’s a tut there .

#this is one of the scripts i’m working with, can anyone point out any problems?

from Rasterizer import *
own = GameLogic.controller(guy).owner(cam)
own.setViewport(0, 0, 1024, 384)
