When I try to move graphical objects across the screen at steps which are not whole numbers (for example, 0.5 pixels per frame) this results in choppy and 'laggy' movement; as the object will simply move 1 pixel every two frames.
I understand why this is happening as the x / y values of an object must be Integers, but I wonder if there is anyway to create smooth slow movement, such as there is in Adobe Flash.
