Managing movie clip depths

Every movie clip has its own z-order space that determines how objects overlap within its parent
SWF file or movie clip. Every movie clip has an associated depth value, which determines if it will
render in front of or behind other movie clips in the same movie clip Timeline. When you create
a movie clip at runtime using
MovieClip.duplicateMovieClip()
specify a depth for the new clip as a method parameter. For example, the following code attaches
a new movie clip to the Timeline of a movie clip named
container_mc.attachMovie("symbolID", "clip_1", 10);
This creates a new movie clip with a depth of 10 within the z-order space of
For example, the following code attaches two new movie clips to
named , will render behind
clip_1
container_mc.attachMovie("symbolID", "clip_1", 10);
container_mc.attachMovie("symbolID", "clip_2", 15);
Depth values for movie clips can range from -16384 to 1048575.
The MovieClip class provides several methods for managing movie clip depths: see
MovieClip.getNextHighestDepth()
