Our ActionScript courses use version 3. Version 3, available along with version 2 in Flash CS3 and CS4, is a more robust programming language preferred by programmers. It uses standard programming conventions. Version 2 is a simpler scripting language that is more suited for designers without programming experience. If you are using Version 2, our courses present many similar terms and concepts, but would not directly apply to version 2.
