Attatching library behaviors during runtime?

Question

Well I have a graphic on the screen (not on the score but it's a child object that takes a sprite channel when it's created) but I want it to appear using the "Pixelate" behavior from the library. I want to know if by asigning it to a sprite scriptInstanceList or scriptList (and maybe then running a custom on runPropertyDialog event handler that I would have to create cause it's not present in the original "pixelate" behavior, although I guess that's not big deal doing through a duplicate of the behavior) it could be posible to effectively apply this interesting effect. The other alternative I'm thinking about is copying the parts of the behavior that I want into my scripts and adapt them as needed.

Answer 1

This is how I have made it to work, finally I think it's necesary to add it to the scriptInstanceList of the same sprite or else (in my testings) won't work. Thanks again! property values can be altered in the new handler but keeping in mind the limits established by the designers for these parameters (check on getPropertyDescriptionList for this).
- Calling code from outside:
RIGHT AFTER CREATING THE INSTANCE OF THE GRAPHIC:
       _pixelate= new(script"customPixelate", theGraphicSpNum)
       add(sprite(theGraphicSpNum).scriptInstanceList, _pixelate)
       _movie.call(#beginSprite, _pixelate)
- Inside a custom version of pixelate:
     property spriteNum
     property appearWhen, pixelateDuration, horizontalPixels, verticalPixels, minimumDim
     on new me, aSpNum -- for implementation via lingo
       spriteNum= aSpNum 
       appearWhen = "beginning of sprite" 
       pixelateDuration = 50
       horizontalPixels = 3
       verticalPixels = 3
       minimumDim = 4
       return me
     end new
Just for your reference the original behavior is under window/library palette and then animation/sprite transitions/pixelate
