Flash Tutorial - Displacement Map Filter & Animation
Flash 8 Pro introduces many graphic filters including the Displacement Map Filter which allows you to distort a Movie Clip based on a bitmap's color values. The Displacement Map Filter distorts the colors in one object based on the color of another object. This gives you a distorted effect.
The DisplacementMapFilter class uses the pixel values from the specified BitmapData object (called the displacement map image) to perform a displacement of another object on the Stage, such as a Movie Clip instance. You can use this filter to achieve a warped or mottled effect on a BitmapData or Movie Clip instance.
Here is how the DisplacementMapFilter class works. The Displacement Map Filter is applied with the use of ActionScript. For each pixel in the destination bitmap, the DisplacementMapFilter class does the following:
In this tutorials you will create the Flash Movie below, learn how to swap the images and learn how to edit the code so that the animation is triggered on different type of events like mouse roll over. Here is one of the Movies that you will be creating using the Displacement Map filter:
Note: If the Movie below is not animating - refresh your web page: Ctrl F5
