actionscript 3 - Variable embedded source AS3 -

i'm making little memory game multiple themes cards , backgrounds. i've managed make possible 1 set of images embedded game want make possible have more themes. in order make happen use 8 times differen cards:

public var c1:string; [embed(source = c1)] public var card1:class; 

with made constructor such:

public function theme( _c1:string) { c1 = _c1; } 

now in different class specified themes use constructor such:

var fruit:theme = new theme (".../lib/apple.jpg"); 

now believe makes new object of theme string c1 source picture , uses string source make picture off of putting in embed source, these error messages:

c1 not have recognized extension, , mimetype not provided.  unable transcode c1 

how can prevent this?

what you're trying here pass variable (which happens in runtime, after swf compiled) embed metatag preprocessed @ compile time (before application aware of actual theme string value).

there 2 solutions. new swf file per each theme. define resource theme constant, not variable:

[embed(source = 'path/to/resource')] 

if want use 1 swf, must rethink application design , load theme @ runtime, initializing loader, fetching resource, creating new theme resource , start actual game code.

class theme extends eventdispatcher {     public static const theme_ready = 'themeready';     private resource:bitmap;     public function theme(resourceuri:string) {       loadresource(resourceuri);    }    private function loadresource(path:string):void {       var loader:urlloader = new urlloader(new urlrequest(path));       loader.addeventlistener(event.complete, onresourceloaded);    }    private function onresourceloaded(e:event):void {       e.target.removeeventlistener(event.complete, onresourceloaded);       this.resource = e.target.content;        initialize();       dispatchevent(new event(theme_ready));    } } 

game initialization:

var themeresource:string = 'path/to/resource.jpg'; var theme:theme = new theme(themeresource); theme.addeventlistener(theme.theme_ready, initializegame);
