Class SmoothMover

java.lang.Object
greenfoot.Actor
SmoothMover
public abstract class SmoothMover extends greenfoot.Actor
A variation of an actor that maintains a precise location (using doubles for the co-ordinates instead of ints). This allows small precise movements (e.g. movements of 1 pixel or less) that do not lose precision.
