Hi,
It's good and highly recommanded that eventually, you master both PlayMaker and regular scripting, this is the best combination you can dream of. I tweeted yesterday about this soccer game that is using PlayMaker just for the visual fsm thingy and each state is just calling a regular script. PM becomes the backbons of your logic, the authoritative source of the current state, but doesn't have to deal with more if you don't want to.
I remember years ago I saw a team using PlayMaker on a big game with very complex UI, and they were using PlayMaker the same way, all panels, windows, animations for the UI were handled by PlayMaker, and scripts controlled it and relied on it, while implementing other features in pure code.
Bye,
Jean
