ActionScript 3.0 Presentation and Examples
Back in November, Danny Dura and I did a small world tour to talk to our international communities about ActionScript 3.0. Danny did Europe, and I did Asia. We put together a PowerPoint presentation (which you can view here), and several good code examples (which you can download here). The presentation covers:
- Regular Expressions.
- E4X. The new and very simple way to create, parse, and query XML in ActionScript 3.
- ExternalInterface API. Allows your Flash content to communicate with its container (usually the HTML page via JavaScript) without any additional libraries.
- File upload. Shows how to upload a file using Flex and save it on the server using ColdFusion. (File upload is actually already available in Flash 8.0, but this is a Flex 2 example).
- Data types. Lists all the ActionScript 3.0 data types and their default values.
- Operators. Demonstrates some of the ActionScript 3.0 operators.
- Packages. Demonstrates how packages work in ActionScript 3.0.
- Rest arguments. ActionScript 3.0 supports a concept of "rest arguments" which you allows you to make some argument required, and also handle an arbitrary number of additional arguments.
- Proxy. The flash.util.Proxy object is a more powerful version of __resolve.
- Reflection. Shows how to introspect ActionScript 3.0 classes.
- Timer. Shows how to execute code at a specified interval.
- The new display list API.
To run these examples and build your own Flex 2.0 applications, you'll need to grab the Flex Builder 2 alpha from Adobe Labs.
