Assigning a class to a movie clip
To assign a custom class to a movie clip, you use the registerClass
property of the Object class. The registerClass
property takes arguments for a symbol linkage identifier (which identifies the movie clip) and a class. For example, this code assigns the class Ball to a movie clip that has the symbol linkage identifier myBall
.
Object.registerClass("myBall",Ball);
The symbol linkage identifier must be enclosed in quotation marks.
You can also remove a custom class previously assigned to a movie clip, by entering null
for the class
argument.
Note: You assign a symbol linkage identifier to a symbol in the Linkage Properties dialog box (choose Linkage from the Library options menu). For more information, see Dynamically adding a movie clip or sound to the Stage.
To assign a custom class to a movie clip:
Use the following syntax:
Object.registerClass("symbolID",class);
To remove a custom class assigned to a movie clip:
