ActionScript 3 introduced new ways to load content and new types of content – now Flash can handle raw bytedata. This also increased the complexity of the process. You need a Loader, URLLoader, URLRequest, event listeners…
ContentLoader is a class that simplifies the process into a one class that can fulfill most of the basic needs:
– send and load data
– load bytedata
– load variables
– hande errors
– load images, mp3s, xml, text (JSON too, of course, but parsing is not supported)
Example:
//listeners
_loader = new ContentLoader();
_loader.addEventListener(Event.COMPLETE, loader_INIT);
_loader.addEventListener(ErrorEvent.ERROR, loader_ERROR);
_loader.addEventListener(ProgressEvent.PROGRESS,loader_PROGRESS);
_loader.addEventListener(Event.INIT, loader_INIT);
_loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, loader_HTTP_STATUS);
//load different media (there are more)
_loader.loadText("variables.txt");
_loader.loadVariables("login.php",{name:"user",pwd:"kfj3i92dlakls"});
_loader.load("image.jpg");
// finished
//if it was an image
addChild(_loader.content);
//if it was text
var text = _loader.content;
//if it was variables
var var = _loader.content.variable;
// clear the loader
_loader.destroy();
_loader = null;
