CHAPTER 3
Sprites
A sprite is an object that controls when, where, and how cast members appear in a Macromedia
Director MX 2004 movie. Multiple sprites can use the same cast member. You can also switch
cast members assigned to a sprite as the movie plays. You use the Stage to control where a sprite
appears, and you use the Score to control when it appears in your movie.
Sprites appear on the Stage layered according to the channel in which they are assigned in the
Score. Sprites in higher-numbered channels appear in front of sprites in lower-numbered
channels. A movie can include as many as 1000 sprite channels. Use the Movie tab of the
Property inspector to control the number of channels.
Sprite properties include the sprite’s size and location, the cast member assigned to the sprite,
the sprite’s name, and the frames in which the sprite occurs. Different properties can alter the
appearance of a sprite. You can rotate, skew, flip, and change the color of sprites without
affecting cast members. You can change sprite properties with the Property inspector or Lingo
or JavaScript syntax.
You can also give each sprite a unique name. You can assign a name by using the Property
inspector, and then view the sprite by name in the Score and on the Stage. Assigning a name lets
you refer to the sprite by that name in Lingo or JavaScript syntax and not just by the channel
number that it occupies. You can move a sprite to a different channel and not worry about
changing scripts. Editing scores and code scripts is much easier when you refer to a sprite by
its name.
In Lingo or JavaScript syntax, some properties are available only for certain types of sprites. Such
properties typically are characteristics that are related to the specific sprite type. For example,
Lingo or JavaScript syntax has several digital video properties that determine the contents of
tracks in digital video sprites.
