Constructor Details

#initialize(dialog = nil) ⇒ Controller

This puts together the initial dialog and the user ones that are hooked into it.

The initial dialog needs an state defined as initially. This is where it will start.

Example:

initially :awake
state :awake do
  # ...
end

If you don’t give it an initial dialog, James will simply use the built-in CoreDialog.
