Creating timeout objects
You can create a timeout object—a script object that acts like a timer and sends a message when
the timer expires. This is useful for scenarios that require specific things to happen at regular time
intervals or after a particular amount of time has elapsed.
Timeout objects can send messages that call handlers inside child objects or in movie scripts. You
create a timeout object by using the
handler to be called, and the frequency with which you want the handler to be called. Once a
timeout object is created, Director keeps a list of currently active timeout objects, called
