In a recent prototyping project, I attempted to simulate “shake” gestures in a desktop AIR application, i.e., using mouse cursor to simulate a hand grabbing some object on the screen…
Anyhow. I found out that Flash Player can send out the mouseMove event must faster than it can update the screen. In the case you want to keep track of the simulated gestural motion, you would want to track the mouse cursor position on the stage, instead of the display object the mouse cursor is dragging. This is because when you drag the object to the point Flash Player cannot keep up with, the redaw will then not necessarily reflect the real positional changes of it in between the frames.
Take a look here. Right click to for the code. Also note that when directly register Application.application as the currentTarget we seem to get smoother tracking than if we registered the display object, like so:
mButton.addEventListener(MouseEvent.MOUSE_MOVE, mButton_handleMouseMove);/** you got more stripped out points than if you do this:
addEventListener(MouseEvent.MOUSE_MOVE, mButton_handleMouseMove);// this is btter.*/
