AS3Wrapper

AS3Wrapper imports Flash libraries into Javascript.

• Full Flash API
• Construct Flash objects directly in Javascript
• Pass objects, functions and primitives to methods directly
• Module system, with Papervision3d
• Works with IE 5.5, 6 and 7 and Firefox 2.0

Simple Example

Javascript code with AS3Wrapper

with(playerInstance)
with(flash.display)
with(flash.net){  
	var image = new Loader();
	image.load(new URLRequest(url));
	addChild(image);
}

Equivalent ActionScript 3.0 code

import flash.display.*;
import flash.net.*;
... {
	var image:Loader = new Loader();
	image.load(new URLRequest(url));
	addChild(image);
}

Live Examples

• 1. Drawing a scene
• 2. Loading an image
• 3. A text-effect with scalable fonts
• 4. Papervision3d Cube

Coding Differences

There are a few programming differences you have to adhere to:

• Types: Leave them out.

• Getters and Setters: Use object.getName() in place of object.name.

• Imports: In place of ActionScript import statements, you should use with blocks. For example, you can use with(flash.display){new Sprite();} to create a new Flash object from the class flash.display.Sprite.

• Multiple Virtual Machines: A web page can contain multiple instances of the Flash player. Therefore, when you write Javascript that you want to execute for the player named player, be sure to enclose it in a with(player) {} block. This ensures that any newly constructed objects are created in the correct virtual machine.

Running Locally

The Flash player won't let you run javascript in a page that's being hosted on the local file system. To get around this for development, you can:

• View local file using a web server on localhost and http, or

• Set your local AS3Wrapper.swf to be trusted by following these instructions.
