Creating content for Flash Player 4

To use Flash MX 2004 to create content for Flash Player 4, specify Flash Player 4 in the Flash tab of the Publish Settings dialog box (File > Publish Settings).

Flash Player 4 ActionScript has only one basic primitive data type, which is used for both numeric and string manipulation. When you author an application for Flash Player 4, you must use the deprecated string operators located in the Deprecated > Operators category in the Actions toolbox.

You can use the following Flash MX 2004 features when you publish for Flash Player 4:

• The array and object access operator ([])
• The dot operator (.)
• Logical operators, assignment operators, and pre-increment and post-increment/decrement operators
• The modulo operator (%), and all methods and properties of the Math class

The following language elements are not supported natively by Flash Player 4. Flash MX 2004 exports them as series approximations, which creates results that are less numerically accurate. In addition, because of the inclusion of series approximations in the SWF file, these language elements take up more room in Flash Player 4 SWF files than they do in Flash Player 5 or later SWF files.

• The for, while, do..while, break, and continue actions
• The print() and printAsBitmap() actions
• The switch action
