| Q1: | I did the Car with Rotating Wheel task, but when I first made the Rotating Wheel symbol, I forgot to specify the default symbol behavior as Movie Clip. I went back to the Library to rectify this error, but it still doesn't work (the wheels don't rotate). Why not? |

A1:
| Changing the symbol properties of the item in the Library affects only any new instances you drag from the Library, which will have the properties of the master in the Library. However, instances already in a movie will have the same behavior they started with. Your instances of the Rotating Wheel symbol are behaving like graphics. Go to where they're used (inside the Car symbol) and, with the Properties panel open, select each instance. Then change the Symbol Behavior setting from Graphic to Movie Clip. |

A2:
| You could have seen Loop Once in the Properties panel, but not when a movie clip was selected. Only instances behaving as graphics have this option—which is a good reason to use Graphic symbols. Of course, when you become accomplished with ActionScript, you'll find ways to achieve the same effect when using a movie clip—although it still might take more work than simply using the option available to instances of graphics. |
