In this tutorial we discuss the ENTER FRAME event in ActionScript 3. The Enter Frame event is used when you want to have an event fire repeatedly as the application is executed. Care must be taken in using this event as it is processor intensive. We discuss using the Enter Frame event as a way to animate objects in ActionScript. We work with dynamic Sprites in the demonstration and discuss the proper code syntax to initialize and execute the Enter Frame event. Building a small application we use the Enter Frame event to animate an object across our stage. We use filter properties in our demonstration to add a little more complexity and control to our ActionScript demonstration.
