Statemachine?

No one knows what im talking about?

A finite state machine? There are countless implementations of the finite state machine; it all depends on the needs of your design. What are you looking for?

Not really sure, my state machine (for game states) works like a stack, you can push/pop but you can also clear the entire stack and start a new. If your att he main menu you can go into options etc and pop back out but if you want to go to "new game" then you no longer need the main menu so I clear and push a new state.

I've yet to come across a situation where one state needs information about another but I was thinking and if I had a "loading" state where a level is loaded then that might be a candidate. I'd planned to just pass in a referance to the required information rather than the loading state accessing it. The whole tell, don't ask thing.

I just had a look, my game state machine uses a vector inside (stl). Its using that rather than a stack as sometimes I want a state to be updated/rendered beneath the current one, a stack only lets you access the top.

Do you mean Vector as in STL Vector Container?

I suppose its like a stack based state machine?

Google Stack based FSM or stack based state machine and you might get what you want.

If you go to options and change settings, then pop if off, wont the settings be lost?


And also thanks everyone for telling me what it was called

Depends how its implemented, I have a semi-global "options" object. Though it is only really used by my main game state so I guess it could live there and be passed around.
