Summary

• Collisions occur when two or more elements in a Flash movie touch each other. Whenever the space by one Movie Clip instance occupies the space of another, a collision, or "hit," has occurred.

• You can detect simple user-initiated collisions by using the startDrag() method and _droptarget property of the MovieClip object.

• Using the hitTest() method of the MovieClip object, you can detect the intersection of X and Y coordinates with a specified Movie Clip instance. You can also use hitTest in a similar fashion to _droptarget, where the overlap of two specific Movie Clip instances is detected.

• You can use the ColorTransform class to create new color values and apply them to Movie Clip instances.

• You can create sound libraries in less time by using ActionScript and the Sound object. You create Sound objects by using Linkage identifiers for sound files in the movie's Library.

• By using the new PrintJob class, you can output high-quality artwork to a PostScript or non-PostScript printer.
