So, from what I understand there is a runagsgame function. But what do you do after? and is it possible to put a 3d game within a 2d game? I would be really thankful for any help offered.
It depends on what kind of '3D' games you're after.
As the name suggests, RunAGSGame() is for running another game made with AGS only.
So basically it depends on what you can do with AGS.
AGS is not designed for 3D games but with some scripting or plugins you can do some '3D' effects to some extend. There're a couple of threads about making 3D stuff with AGS. You may try to search for them.
thanks.
