Troubleshooting ActionScript > Using the Debugger
Using the DebuggerThe Debugger allows you to find errors in a movie as it's running in the Flash Player. You can view the display list of movie clips and loaded movies and change the values of variables and properties to determine correct values. You can then go back to your scripts and edit them so that they produce the correct results. To use the Debugger, you must run the Flash Debug Player, a special version of the Flash Player.
The Flash Debug Player installs automatically with the Flash 5 authoring application. It allows you to download the display list, variable name and value pairs, and property name and value pairs to the Debugger in the Flash authoring application.
To display the Debugger:
Choose Window > Debugger.
This opens the Debugger in an inactive state. No information appears in the display list until a command is issued from the Flash Player.
To activate the Debugger in test-movie mode:
Choose Control > Debug Movie.
This opens the Debugger in an active state.
