Well for one, read the tutorial that R.E.B submitted. That will help with the identifying the dupes.
Now dependent on how the movieclip will follow your character, the code need changes.
If its a platformer the AI needs to recongize walls, jumps and well platforms. If its a free
view, like over the head 3d roaming movement, then it might be as simple as
if(this._x<_root.guy._x){_x+=3}...etc.
However depending on how much depth you want to go on with the project yo'll
have to figure out the many circumstances that the computer AI will face.
After you identify the scenarios then you can begin to properly code what you
want.
That's my bit of two cents. If you can give me more info I can try to help some more.
However I too am currently facing this problem and trying to decide how to create
A competent AI structure.

Ok here is how it works,I have a gun and a dot,I programmed the gun to shoot and i want it to follow the dot like some fairy or sumthing.That way while the dot is moving i can just click and shoot(i already programmed the click and shoot)so with the code i can have the gun following instead of standing there.

So wait, are you saying that the "gun" is basically being held by the "dot"?
If that's the case all you have to say is that (_root.gun._x=_root.dot._y;_root.gun._y...etc).
If that is not what you meant then I'm sorry but I'm a bit confused at your post.
