Learn the notes of ActionScript axu

Today, I am working on a blog system, using the Avatar upload function, and using flash for implementation. Actionscript3 is not well received, so I wrote several diaries in my study.

1. The As script file is associated with the FLA file. The As script file under the FLA directory is automatically loaded. You can also choose "menu file"> "Settings"> "add path" to associate the as files in more folders.

2. Enable the FLA file to automatically execute the as class selection menu: file-> ActionScript settings-> Add "document class". Enter the relevant class name to load the SWF, class in the specified as is initialized.

3. How to Write a control using the As script to write a class, inherit Sprite and movieclip. And draw the interface and add events.
