I may be missing something obvious here, but I've been wondering what the best strategy is for implementing a global game controller function? Like a main() update loop in traditional programming.
I intend to use this to track game state changes, centralise events, instantiate objects etc. From what I understand Unity seems to expect a script to be attached to a GameObject, there doesn't appear to be a 'world' object I can apply an update() function to.
I would also like this 'world' object/function to be able to receive propagated events in the hierarchy.
I just need a tip to set me on the right path, the paradigm Unity uses to deal with this more traditional programming paradigm.
