Color Matrix 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.ColorMatrixFilter;

   // Defines which colors to change.
   var myMatrix:Array = [2,0,0,0,0,   /* Red */
                         0,1,0,0,0,   /* Green */
                         0,0,2,0,0,   /* Blue */
                         0,0,0,1,0 ]; /* Alpha Transparency */

   // Creates a variable with info about the Filter settings.
   var colorMatrix = new ColorMatrixFilter(myMatrix);

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

    

   Note: If you wish you can type the Matrix in a more standard format like this: [2,0,0,0,0,0,1,0,0,0,0,0,2,0,0,0,0,0,1,0]; Or like this: [2,0,0,0,0, 0,1,0,0,0, 0,0,2,0,0, 0,0,0,1,0]; I have spread it out into a matrix as this makes it is much easier to understand and edit. If you wish to type the code in a matrix format make sure you don't get your commas (,) and semi colons (;) mixed up. If you do you will get errors. There is only one semi colons (;) which defines the codes end of line: [2,0,0,0,0,   /* Red */  0,1,0,0,0,   /* Green */  0,0,2,0,0,   /* Blue */  0,0,0,1,0];  /* Alpha Transparency */ If you wish you can leave out the gray comments and white space. I only add the comments and space to make the code easier to read and edit. It could just as well be typed like this: [2,0,0,0,0,  0,1,0,0,0,  0,0,2,0,0,  0,0,0,1,0];
