Simple Drag Function within an AS file

I have a movie clip Screen which contains another movie clip dragger. (a drag bar)

I will be attaching instances of this clip as needed.

What I want to do is write a function so that when the dragger bar is pressed in any of the instances of the Screen clip, that instance of Screen can then be dragged.

This function resides in a class Screen which is linked to the movie clip and I am using AS 2.0

This is more or less what I have come up with

Code:

---

function drag() {
        dragger.onPress = startDrag(true);
        }

---

What's throwing me is the paths and use of this in AS 2.0 I know it's simple, sorry this is my first class.

Thanks for your help

One way to do it would be to attach the following script to the dragger instance:

code:

---

on(press)

{

  _parent.startDrag();

}



on(release)

{

  _parent.stopDrag();

}

Hi,

Thanks but I am trying to centralize all the code which is common to the Screen clip. It's got to be something simple, I just can't see it.

code:

---

function setupdrag() 

{

	dragger.onPress = function()

        {

          this._parent.startDrag();

        }

	dragger.onRelease = function()

        {

          this._parent.stopDrag();

        }

}

---

That does it

Thanks

I am running into another problem. Can't figure it out.

The function works as long as I include Screen for example: Screen.dragger.onPress Of course In actuality it would be Screen1, Screen2 etc...

So here is the button action, I pass the id to the as file.

Code:

---

attachMovie("Screen", "Screen1", 2, {id:1});

---

In my .as file I declare the var

Code:

---

var capt:String, id:Number;

---

In the constructor I add the full path

Code:

---

function Screen() {
                path = "Screen" + id + ".dragger";
                trace(path);
}

---

It traces out correctly even when I trace it from within the function but it only works if I hardcode the path.

is this a type mismatch? what is going on?

Thanks

First off in when attaching the movie, you need to name the clip using a dynamic id number, like so:

myID = 2;

attachMovie("Screen", "Screen"+myID, 2, {id:myID});


Secondly, your path is a string:

path = "Screen" + id + ".dragger";

You'll need to evalulate it to use it like a movieclip.

path._x += 3; // invalid
mc = eval(path);
mc._x += 3; // valid

Yes, that will work, thanks.

I thought they had done away with eval in 2.0
