Is there anyway to have split screen sections in a game? Would make for interesting puzzles I think. I tried a search but didn't find anything.
Split screen? As in parallax scrolling?
Then no, AGS current doesn't suppost this feature.
If by puzzles you mean stuff like sliding puzzles just use sprites (as objects, characters or overlays).
No I mean the game screen being split in two with one character on one screen and another on the other. Could even be in two different rooms.
You can just use one room for this (like this game (http://www.adventuregamestudio.co.uk/games.php?action=detail&id=815)). But you can't make them scroll independently (as in parallal scrolling like I mentioned).
In two different rooms: no.
Weeeeelll...
I think it might be possible to simulate behaviour like this by getting creative with objects, interactions, regions and the like. But it will be extremely complicated to get something like this to work.
Coming to think of it, might be worth a try. :=
