Runtime Versions: Flash Player 10, AIR 1.5

The Move effect move the target object in the x and y directions. The x and y property specifications of the Move effect specify the change in x and y that should occur to the transform center around which the overall transform occurs. If, for example, the autoCenterTransform property is set, then the from/to/by values in this effect will define how much to move the center of the target, not the (x,y) coordinates of the target.

Like all transform-based effects, this effect only work on subclasses of UIComponent and GraphicElement.

The <s:Move> tag inherits all of the tag attributes of its of its superclass, and adds the following tag attributes:

  <s:Move

    yBy="val"
