How Do I Use the Double wide screen trick like in Project Boom
I found out using the double screen was pretty crucial in my game so I took a look at the overview on project boom because I remember seeing it in there but I still am a bit edgy on it

There are a # of components and attributes that have to be triggered in order for everything to work well. You would have to have self.attributes for the objects on the right to record the starting position. You would need game.attributes for saying when to bring those objects on-screen.
It wouldn't be a walk in the park to say the least, but it is definitely doable and very useful. If you have no idea where to start to figure it out on your own, I would recommend looking for a template that incorporates the double-wide screen so you could see how somebody else uses it. Let me know if you can't find anything and I'll have a quick look around.

Then drag an actor into the scene to put your scene rules in. Click on the instance in the the scene and unlock the pad lock icon. Then create a rule that says when game.pause (or whatever) is true interpolate current scene.camera.origin.x to 420 (for iPhone) or (1024 for iPad).
The key is to have your game elements on a NON-scrolling layer (uncheck the scrollable box in the layer pannel under scene) and your off screen stuff on a scrolling layer.
