如何使得两个相互拖动控制得MC的跟连运动更为流畅？两个MC:mc0,mc4;想使得拖动任意一个MC时，另外一个都能一起被拖动。如果快速拖动鼠标，两个相互控制MC之间的跟随运动却有迟缓，并不是紧紧跟随？请大家指教！
第一帧Action:
_root.onLoad = function() {
_root.mc0.useHandCursor = false;
_root.mc4.useHandCursor = false;
};
_root.mc0.onPress = function() {
_root.mc0.startDrag();
_root.onMouseMove = function() {
_root.mc4._x = _root.mc0._x;
_root.mc4._y = _root.mc0._y-_root.mc0._height;
};
};
_root.mc0.onRelease = function() {
_root.mc0.stopDrag();
_root.mc4._x = _root.mc0._x;
_root.mc4._y = _root.mc0._y-_root.mc0._height;
};
_root.mc4.onPress = function() {
_root.mc4.startDrag();
_root.onMouseMove = function() {
_root.mc0._x = _root.mc4._x;
_root.mc0._y = _root.mc4._y+_root.mc4._height;
};
};
_root.mc4.onRelease = function() {
_root.mc4.stopDrag();
_root.mc0._x = _root.mc4._x;
_root.mc0._y = _root.mc4._y+_root.mc4._height;
};
