the SWF file, click the movie clip to rotate it:
this.createEmptyMovieClip("triangle", this.getNextHighestDepth());
triangle.beginFill(0x0000FF, 100);
triangle.moveTo(100, 100);
triangle.lineTo(100, 150);

setMask (MovieClip.setMask method)

public setMask(mc:Object) : Void
Makes the movie clip in the parameter a mask that reveals the calling movie clip.
mc
The method allows multiple-frame movie clips with complex, multilayered
setMask()
content to act as masks (which is possible by using mask layers). If you have device fonts in a
masked movie clip, they are drawn but not masked. You can't set a movie clip to be its own
mask, for example, .
my_mc.setMask(my_mc)
If you create a mask layer that contains a movie clip, and then apply the method
setMask()
to it, the call takes priority and this is not reversible. For example, you could have
setMask()
a movie clip in a mask layer called that masks another layer that contains another
UIMask
movie clip called . If, as the SWF file plays, you call ,
UIMaskee UIMask.setMask(UIMaskee)
from that point on, is masked by .
UIMask UIMaskee
To cancel a mask created with ActionScript, pass the value to the method.
null setMask()
The following code cancels the mask without affecting the mask layer in the Timeline.
UIMask.setMask(null);
You can extend the methods and event handlers of the MovieClip class by creating a subclass.
