-
ActionScript has several data types, including Boolean, Function, MovieClip, Number, Object, and String.
-
You should create a procedure when the same actions are repeated within a Flash movie, or when you want to avoid storing long action lists within Button instances.
-
A function is defined with the function action, in the format function name (arguments){actions}.
-
Arrays can manage related information, such as lists. An array is initiated with the Array constructor, as in myArray = new Array();.
-
Array elements have an index number, indicating their position in the array. Array index numbers start with 0 and increment by 1 with each new element.
-
Functions can be used as methods of ActionScript objects. You assign a method by creating a unique method name after the object and setting the method's value equal to a function name (for example, mcMenu.createMenu = createMenu;). Parentheses and arguments are omitted from the method assignment.
-
You create objects with the function constructor. Functions intended for this use describe properties and methods for objects using the this target path. You create a new object by specifying an object name and setting its value equal to a new instance of the function name, as in myObject = new SoundLibrary(1,7);.
