 Subject: Flash class review and Quiz Two on Wednesday...

    1.  The Flash quiz two, as any of you know who were at class today,
           will be on Wednesday.  We had a very productive class today,
           in my estimation, so I am not disappointed we kept going into
           the car with rotating wheels concepts.  Using theBlueBlade and
           theGreenBlade to illustrate the need for Library Symbols to be
           building blocks for GreenRotatingBlade and BlueRotatingBlade,
           i.e. Symbols that have their own Timeline, so they can have their
           own animation (Motion Tween between two theBlueBlades, for example,
           for the BlueRotatingBlade, was very useful, I hope.

    2.  The Flash cars assignment will not be due until Friday.  Help with
           uploading it can come again in class demo on Wednesday, using
           Dreamweaver and in hands-on class on Friday, using Dreamweaver.

    3.  If you need help uploading Flash, just let me know and I can help
           you.  Please make an appointment by email or see me after class
           or before class.

    4.  One thing I have discovered is confusing is the naming of the
           instances of theRotatingWheel.

        Your assignment will have TWO instances of theRotatingWheel.

        You can name them (instance name, not Symbol name) something like

             rearWheel and frontWheel    or     rearTire and frontTire

        Suppose that the instance of theCarSymbol from your library that
           you animate on the Stage using the main timeline and a motion
           tween to go from off stage left side
                         to off the stage exit right side is named
                                                                   theCar. 
        Remember, every instance of theCarSymbol has two named
           component symbols, i.e. the two instances of theRotatingWheel
                                                                  symbol.

        Suppose you named your theCarSymbol wheels rearWheel and frontWheel.
                                                   ---------     ----------

        How do you start the car's wheels rotating again, if they are
            stopped?

            this.theCar.rearWheel.play();

            this.theCar.frontWheel.play();

        --
        If your theCarSymbol instance is named theCar and theRotatingWheel
        --                                     ------     two instances
                                                          it uses are
                                                          called
                                                               rearWheel
                                                          and frontWheel!

         How do you stop the wheels from rotating?

               this.theCar.rearWheel.stop();

               this.theCar.frontWheel.stop();

         How do you stop theCar from moving across the stage over and over?

               stop();

         How do you start theCar up again so it drives across the stage again?

               play();

         What would the following button do when you clicked it?

             on (release) {

                 play();

                 this.theCar.rearWheel.stop();

                 this.theCar.frontWheel.stop();
             }

      It would start theCar moving from KF#1 (off stage to left side)
                                     to KF#2 (off stage, exit right side),

         i.e. start theCar driving across the stage over and over again
              from the start KF position
                to the finish or final KF position.

       Yet theCar would be skidding its tires, as neither tire would be
       rotating because of the stop() command you gave to that tire on
       that car.               $$$$$$                          ****
            ^^^

                 this.theCar.rearWheel.stop();
                      ^^^^^^ ********* $$$$$$
                        car    tire     command

       This should help, especially if you study it in conjunction with
your notes and handouts and the class web page AND take notes about it 
too.  Experimenting and playing around and trying things out in Flash 
is very good too.

       What would the code look like for stopping only the car?

       on (release) {
          stop();
       }

       What would the code look like for stopping only the tires?

             on (release) {

                 this.theCar.rearWheel.stop();
                 this.theCar.frontWheel.stop();
             }

       What would the ActionScript 2.0 code for a GREEN Go button look like
          if it was supposed to start up everything again, assuming that
          the name of the car was theCorvette, and the names of
          theCarSymbol's instances of theRotatingWheel that theCarSymbol
          was made up of were:

                   rear_Wheel and front_Wheel?

       on (release)  {
           play();

           this.theCorvette.front_Wheel.play();
           this.theCorvette.rear_Wheel.play();
       }

       See you on Wednesday for Quiz Two and more ActionScript 2.0.
