Repeating an animation using the AnimateProperties class in Flex and Flash Player 10

The following example shows how you can repeat a property animation in Flex with the beta Gumbo SDK and Flash Player 10 using the AnimateProperties class and repeatCount property.

Full code after the jump.

To use the following code, you must have Flash Player 10 and a Flex Gumbo SDK installed in your Flex Builder 3. For more information on downloading and installing the Gumbo SDK into Flex Builder 3, see “Using the beta Gumbo SDK in Flex Builder 3″.
