Play a movie clip 241

Next, you’ll specify what the function does: it plays the movie clip on

the root Timeline, which is the main timeline. In your script, you’ll

refer to the movie clip by the linkage identifier name in the Linkage

Properties dialog box (MCTrio).

Additionally, even though you didn’t place an instance of the MCTrio

symbol on the Stage, you’ll use ActionScript to create an instance name

for the symbol. The instance name that you’ll specify is trio_mc.

3. With the insertion point at the end of the last line of script, press Enter

or Return. Then type the following:

this._parent.attachMovie("MCTrio", "trio_mc", 1);

The number 1 in the script that you just typed refers to the depth on

the layer in which to play the movie clip.

Every movie clip instance has its own z axis (depth) that determines the

stacking order of a movie clip within its parent SWF file or movie clip.

When you use the

attachMovie() method to create a new movie clip

at runtime, you always specify a depth for the new clip as a method

parameter.

Specify movie clip Stage coordinates

In addition to the z axis for the movie clip, you must specify the x and y

coordinates to place the movie clip within the Stage area at runtime.

■ Press Enter (Windows) or Return (Macintosh) after the last line in the

Script pane and type the following:

trio_mc._x = 275;

trio_mc._y = 200;

};

NOTE

For more information about the attachMovie() method, see

attachMovie() in the ActionScript 2.0 Language Reference. Additionally,

you can use the ActionScript 2.0 Language Reference for information

about ActionScript that allows you to manage depth;

getNextHighestDepth(), getDepth(), getInstanceAtDepth() are

methods of the MovieClip class. The DepthManager class allows you to

manage the relative depth assignments of a movie clip.
