The speed multiplier speeds up (or down) execution of all following statements by the factor argument.
In the attached screen shot, you see that I have garfield walk in one loop cycle, then I speed him up by a factor of 4 in the next loop cycle, and then i slow him down to his original speed for the last loop cycle.
I have also attached a copy of the world for you to play with.
Let me know if you have any other questions…

If you look at what it does right now (see attached screen shot), you will see that it essentially builds the current (and only possible) Scene, readying it for execution. It is not a method you or your students need to use at this time.

>>
>> The student should create a boolean variable for the Scene class that is initially set to false as the program runs, and at the time when the student wants the event to become active, he sets the value of the variable to true. He would reset it to false when he no longer wants to listen for the event.
