Create a Gradient Glow Filter with ActionScript

Free Flash Tutorial

Step Two: The ActionScript

1. In the Timeline insert a new Layer:
2. Name the Layer: ActionScript
3. Select Frame 1 of the Actionscript Layer: Frame 1
4. Open the Actions Panel: Window > Actions (F9)
5. If Script Assist is on, Switch it off:

   Note: With Script Assist on you cannot type in the Actions Panel. If you want to learn more about Script Assist see the tutorial on the Actions Panel

6. Type (or paste) the following into the Actions Panel:

   // Makes the filter available to use in the Movie.
   import flash.filters.GradientGlowFilter;

   // The Arrays (lists) below must all have the same number of entries.
   // Lists the colors to use in the Gradient.
   var colors:Array = [0xFF99FF, 0xFFFFFF, 0x990000];
   // Sets the transparency of each color.
   var alphas:Array = [0.5, 0.4, 0.3];
   // Set the position of each color.
   var ratios:Array = [0, 50, 255];

   // Creates a variable with info about the Filter settings.
   var myGradientGlowFilter = new GradientGlowFilter (0, 0, colors, alphas, ratios, 35, 25, 1.2, 1, "outer", false);

   // Applies the filter to the object named myObject.
   myObject.filters = [myGradientGlowFilter];

   Note: It is possible to write this code in a more compact form. The Arrays do not need to be separated out but can be directly included in the parameter settings. I prefer to spread it out as it is easier to edit. But if you wish you could write the code like this: // Makes the filter available to use in the Movie. import flash.filters.GradientGlowFilter; // Creates a variable with info about the Filter settings. var myGradientGlowFilter = new GradientGlowFilter (0, 0, [0xFF99FF, 0xFFFFFF, 0x990000], [0.5, 0.4, 0.3], [0, 50, 255], 35, 25, 1.2, 1, "outer", false); // Applies the filter to the object named myObject. myObject.filters = [myGradientGlowFilter];
