Just as it s easy to forget a comma or to misspell a word when writing a letter it s easy to make mistakes when writing scripts regardless of how familiar you are with ActionScript. However unlike your letter recipients Flash is unforgiving when it comes to script errors. In scripting errors mean bugs and bugs mean your script either won t work at all or won t work as planned. Luckily Flash provides some handy ways to test scripts and stamp out bugs. 1. If isn t already open open it now. This is the file we set up in the last exercise.

Although there are all kinds of ways you can test your movie in this environment determining overall file size streaming capability and appearance we re interested in testing its interactive features which means doing everything we can to mess it up. TIP Enlist as many friends and colleagues as possible to help you test your project. This way you have a greater chance of testing every possible scenario and thus finding all the potential bugs. 3.
