Creating MovieClip objects with ActionScript
Flash Player 9 and later, Adobe AIR 1.0 and
way of adding content to the screen in Flash is by dragging assets
from the library onto the Stage, but that is not the only workflow.
For complex projects, experienced developers commonly prefer to
create movie clips programatically. This approach brings several
advantages: easier re-use of code, faster compile-time speed, and
more sophisticated modifications that are available only to ActionScript.
The display list API of ActionScript 3.0 streamlines the process
of dynamically creating MovieClip objects. The ability to instantiate
a MovieClip instance directly, separate from the process of adding
it to the display list, provides flexibility and simplicity without
In ActionScript 3.0, when you create a movie clip (or any other
display object) instance programatically, it is not visible on the
screen until it is added to the display list by calling the
method on a display object container.
This allows you to create a movie clip, set its properties, and
even call methods before it is rendered to the screen. For more
