Stopping the Action

If you published your movie now, the car would start moving as soon as the viewer entered the screen. You want the viewer to click on a button to make the car move. In this exercise you will add a behavior to stop any action before the viewer clicks a button. Later, you will add a button for the viewer to click to start the action. You will use behaviors to control the action. Generally you use ActionScript, a scripting language, to control the action in a Flash document. However, behaviors allow you to control some actions even if you do not know ActionScript.
