This is a purely code based implementation of the ubiquitous gray scale/luminosity
filter. While most common implementations of this effect tend to be timeline based
and therefore lacking in flexibility this little gem of code-driven ingenuity is
free from such constraints and open to wider application. Better yet, this utility
was built with ease of use in mind.
Near effortless two-step setup process involves simply copying the script to a
folder and referencing the script via an "#include" statement on the main timeline.
Once that's done every movieclip will support the fabulous "_grayScale" property.
"Property?" you ask. That is precisely the beauty of this utility. After the initial
setup, the effect is accessible via the "_grayScale" property on ANY movieclip
instance. Allow me to reiterate...A-N-Y MovieClip instance. Just like the standard
MovieClip properties ("_x", "_y", "_xscale", etc.). Hence forth you merely set the
property to a value between 0 and 100 inclusive. Set the property to 100 and viola!
you've got a full grayscale version of your movieclip. Furthermore you can easily
tween the property to fade from color to grayscale and back again using classic
interpolation methods or via the Tween class (or 3rd party tools like tweener).
Coupled with onRollOver/onRollOut event handlers you'll be able to implement the
colorize-on-rollover effect with relative ease. The sample preview above illustrates
this effect, the code for which comes packaged with your purchase of this versatile
utility.
In addition a class based implementation has also been provided for OOP aficionados.
All in all a great tool for any Flash developer to have in his/her arsenal.
