Flash Animation 13: Creating a Simple Preloader

Now you need to double-click on the symbol to enter its editing stage. Because the script that controls the size of our load bar uses a scaling variable, you need to move the central axis point of the shape to the left; the loader scales the fill from 1 to 100%, and will scale based on the location of this point. If it's left in the normal position, it will scale expanding outwards on either side from the center. We want it to scale and expand outwards from the left to right, so we need to use the Free Transform tool to select that central axis point and drag it all the way over to the left edge of the shape.
