For: Stencyl

Version: 3

Works with:

1. Android
2. iOS
3. Flash
4. Windows
5. Mac OSX
6. (Linux)

Note:

1. HTTP URL only (!)
2. Base64 coding required … JPG/PNG is not translated well with setPixel ….

* Download the github mloader haxe package (massiveinteractive)

* Download the signal github package from massiveinteractive

* put the mloader (Src) into the extension directory

* put the msignal (src) into the extension directory

* Code to load something:

<pre>

import mloader.Loader;

import mloader.ImageLoader;

import mloader.Loader.LoaderEvent;

class MLoader{

public static var loader:ImageLoader;

private static var func:Dynamic;

public static function load(url:String, theFunc:Dynamic){

trace("Loading URL :"+url);

loader=new ImageLoader(url);

loader.loaded.add(loaded);

loader.load();

func=theFunc(); // Call Back

// theFunc(); // <- do call back

//

// Load image as a text ...

var m1=new mloader.StringLoader(url);

m1.loaded.add(loadedstring);

m1.load();

}

public static function loaded(event:LoaderEvent<Dynamic>){

trace("mloader.Loader.LoaderEvent: "+event);

}

public static function loadedstring(event:LoaderEvent<Dynamic>){

if(event.type == LoaderEventType.Complete){

// Make an image from the Text !!

if(func!=null)func();

} // complete?

}

}

</pre>
