Help understanding splitscreen

I need to use Split screen for an upcoming game. I have looked at every capx I can find and I still do not understand it. There are no tutorials around, and I just need it to be put as simply as it can be, rather than trying to understand it based on a premade project. If anyone could help me, that'd be great!

You need to define a relative coordinate system for your 2nd "screen" with respect to the actual screen coordinates.

Basically, you have to add 960 to any x coordinate on your 2nd screen.
