Tween a threshold

[Popinjay]

How would one go about tweening a threshold:

 

Such as in the below statement if I wanted the ".8" to tween between say 0 and 1?

 

bData.threshold(bData2,new Rectangle(0,0,bData2.width,bData2.height),new Point(0,0),">=", .8*0xFFFFFF, 0xFFFFFF, 0xffffff, true);

 

Any help appreciated.

nevermind, I just tweened an object I assigned a variable then tweened that with the onUpdate event (to call a routine to change the threshold with the variable on the object).

 

Dunno if there is a better way or not.
