extension idea.

I think using Viewport object is better than using subapplication because you'll code only one game for all players.

i dont know how to use the viewporint split screen eaither.

you can use 2 subapps that are directed to the same frame, you just have to tell the subbapp which player it has to handle(with a global value for exemple)
in the directed frame you have to code an engine that can handle both players (i don't think it's a big deal)

The only problem with viewport object is that you lose the parallax scrolling feature and repeat mode of layers but you'll be able to program only one game without the necessity of synchronized all elements involved in the game between each screen. ;)

I'll release an example soon.

well thx for all the help i found out how to use the sub apps. it still would be cool for an exstenchen. i dont need it now but id still be lazy enuf to use it.

Here is an example of a split screen made with viewport.
