Adding parameters to dynamically created movie clips

Do one of the following:

• Use the following syntax with attachMovie():

  myMovieClip.attachMovie(idName, newName, depth [, initObject]);
  

• Use the following syntax with duplicateMovie():

  myMovieClip.duplicateMovie(idName, newName, depth [, initObject]);
  

The initObject parameter specifies the name of the object whose parameters you want to use to populate the dynamically created movie clip.

1. In a new Flash document, create a movie clip symbol by selecting Insert > New Symbol.
2. Type dynamic_mc in the Symbol Name text box, and select the Movie Clip behavior.
3. Inside the symbol, create a dynamic text field on the Stage with an instance name of name_txt.

   Make sure this text field is below and to the right of the registration point.

4. Select Frame 1 of the movie clip's Timeline, and open the Actions panel (Window > Actions).
5. Create a new variable called name_str, and assign its value to the text property of name_txt, as shown in the following example:

   var name_str:String;
   name_txt.text = name_str;
   

6. Select Edit > Edit Document to return to the main Timeline.
7. Select the movie clip symbol in the library, and select Linkage from the Library pop-up menu.

   The Linkage Properties dialog box appears.

8. Select the Export for ActionScript option, and Export in first frame.
9. Type dynamic_id into the Indentifier text box, and click OK.
10. Select the first frame of the main Timeline, and add the following code to the Actions panel's Script pane:

    /* Attaches a new movie clip and moves it to an x and y coordinate of 50 */
    this.attachMovie("dynamic_id", "newClip_mc", 99, {name_str:"Erick", _x:50, _y:50});
    

11. Test the Flash document (Control > Test Movie).

    The name you specified in the attachMovie() call appears inside the new movie clip's text field.
