# Adding parameters to dynamically created movie clips

When you create or duplicate a movie dynamically using the `MovieClip.attachMovie` and `MovieClip.duplicateMovie` methods, you can populate the movie clip with parameters from another object. The `initObject` parameter of the `attachMovie` and `duplicateMove` methods allows dynamically created movie clips to receive clip parameters. The `initObject` parameter is optional.

For more information, see `MovieClip.attachMovie()``and` `MovieClip.duplicateMovieClip()`.

To populate a dynamically created movie clip with parameters from a specified object:

- Use the following syntax with the `attachMovie` method:

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

- Use the following syntax with the `duplicateMovie` method:

    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.
