Are you wanting the actor to appear moving while staying center screen? ... that is, a scrolling world?

    int imgW = getImage().getWidth();

    if (getX() < imgW/2) setLocation(imgW/2, getY());
    if (getX() > worldW-imgW/2) setLocation(worldW-imgW/2, getY());
    int imgH = getImage().getHeight();
    int worldH = getWorld().getHeight();
    if (getY() < imgH/2) setLocation(getX(), imgH/2);
    if (getY() > worldH-imgH/2) setLocation(getX(), worldH-imgH/2);
    if (lastX < getX() && dx == 0) setLocation(getX()-80, getY());
}
This may or may not be exactly what you want. However, some of it may put you on the right track.
