1. Create two circular objects, and make one larger than the other.

2. Convert both these objects into movieclips.

3. Give the larger circular object an instance name of "parent".

4. Give the smaller one the instance name "child1".

5. Create a diagonal line as shown below.

6. Convert it to a movie clip and give it an instance name of "line".

7. Right click "child1", go to actions, and insert the action:

onClipEvent (load)  

{  

spring = false;  

startX = _x;  

startY = _y;  

spX = 0;  

spY = 0;  

_root.line._visible = 1;  

parentx = _root.parent._x;  

parenty = _root.parent._y;  

_root.line._x = parentx;  

_root.line._y = parenty;  

_root.line._xscale = _root.child1._x-parentx;  

_root.line._yscale = _root.child1._y-parenty;  

}  

onClipEvent (mouseDown)  

{  

startDrag ("", true);  

spring = true;  

}  

onClipEvent (mouseUp)  

{  

stopDrag ();  

spring = false;  

}  

onClipEvent (enterFrame)  

{  

parentx = _root.parent._x;  

parenty = _root.parent._y;  

_root.line._x = parentx;  

_root.line._y = parenty;  


//////  

_root.line._xscale = _root.child1._x-parentx;  

_root.line._yscale = _root.child1._y-parenty;  


//!spring = if false  

if (!spring)  

{  


//code to create the movements  

spX += (startX-_x);  

spY += (startY-_y);  

spX *= .09;  

spY *= .09;  

_x += spX;  

_y += spY;  

}  

} 


8. That's it! Press ctrl+enter to test the movie.
