More Scrolling Function in Flash 5 - Page 3

Before we go any further, open the source FLA and use the the Movie Explorer (Window > Movie Explorer) to take a glance at the movie's structure. Make sure you view all elements in the Movie Explorer, especially Actions, Symbols, Layers and Frames. I extensively commented the ActionScripts (except for the button dragging) so that the source file could serve as a tutorial within itself. Explore both the movie elements and symbol definitions to familiarize yourself with how certain instances retain aspects of their parent symbols. If you have any confusion later on, come back to the Movie Explorer as it will draw out the entire source file tree(s) for you.

Now, view the library (Window > Library). These are the symbols employed by the movie. Some MC instances have the same names as their parent symbols, but others do not. For example the cfb_logic_up MC instance's parent symbol is also called cfb_logic_up, but the button_list MC instance's parent symbol is named scroll_target. Don't let this confuse you: all that matters in the ActionScript code is the INSTANCE NAME and its location within the movie tree.
