ok… you sent me a PM with a request for more detail.
well… I can only guess really.
I’d say that the sliding panels are done by creating a single white fill square the size of the stage.
select the first frame of the layer with the fill, and hit, create motion tween. Select the keyframe that is produced and set the alpha level of the tween with the “effects” panel. probebly 10%.
Select a frame down the timeline a ways and hit F6 to make a keyframe there. Now both keyframes have a 10% alpha level on the square.
Select all the frames and choose menu option, “edit/copy frames”
Paste these frames into as many layers as you need to make an opaque stack of these tanslucent white panels.
Go back to each layer and set out the movement on the last keyframe to have them move off the stage. Adding keyframes or frames to make a more smooth, and realistic exit.
It will not look as good as theirs… not on your first try. Work with the “easing” settings in the “Frame” panel to change how the panels begin and end various slides. Easing is HIGHLY IMPORTANT to making smooth looking movement. “Easing In” means that the movement between the keyframe with the easing set, and the next keyframe in the layer, is reworked to a bell curve, starting slowly and gaining speed until it reaches it’s destination. “Easing Out” uses an oppostie bell curve, starting out fast and slowing until it reaches the next keyframe. Easing is the difference between mechanical movement which is precise, and natural movement which is a “growing”, “feeling” movement.
