Step Seven: ActionScript for the Timeline

The following Actionscript will make the first button move. There is additional code that makes the other buttons follow the first button, a bit like follow the leader.

1. To avoid errors lock the Buttons Layer:
2. Click on the Insert Layer button:
3. Rename the new Layer to: Actions
4. Place the following ActionScript on Frame 1 in the: Actions Layer
   
   // stops the movie on frame 1
   stop();

   // sets the x position for the menu to stop and go back to. You may need to adjust these two settings
   var goto = 30;
   var backto = -80;
   
   // declares a variable called go which will be used to help create the movement
   var go = 0;

   // sets the speed - don't set it too slow
   setInterval(mousePosition, 5);

   // this function is called by the word 'mousePosition' in the setInterval above
   function mousePosition() {
      // sets the x position for the mouse to activate the menu movement
      if (_xmouse<=20) { //adjust number as necessary
         MC1._x = MC1._x+bounce("right");
      }
      if (_xmouse>=110) { //adjust number as necessary
         MC1._x = MC1._x-bounce("left");
      }
   }

   // this function is called by 'bounce' in the mousePosition function above
   function bounce(leftOrRight) {
      // sets the swing properties
      if (leftOrRight == "right") {
         go = (goto-MC1._x);
         go *= .09;
      }
      if (leftOrRight == "left") {
         go -= (backto-MC1._x);
         go *= .09;
      }
      return go;
   }

   Note: If you are struggling to understand the functions above see the tutorial: Intro to functions

5. Test Your Movie: Control > Test Movie (Ctrl + Enter)
6. Place the Mouse over the: Menu bar

   
   So far only the first Button works.

   Note: Only one Button will work. To make the rest of the Buttons work there one more step.

7. Close the Test Window:
