Answer 1

Depending on what scope you want to enforce, you can choose one of the following (going from broad to narrow):

A) Use a singleton object that can be accessed globally and allow it to hold any information you require.

B) Use a global/scoped event bus that allows listening for certain events. Attach the scene as a listener to the event bus. The events then carry the information you need to handle the event.

C) Track scenes manually and call methods directly on Scene instances for the smallest scope.
