Hi,
I don't like the way to use ResourceManager.
Here is my method:
var parser:OBJParser = new OBJParser("../path/myobj.obj");
parser.addEventListener(LoaderEvent.PARSE_COMPLETE,
handleParserComplete);
parser.addEventListener(LoaderEvent.LOAD_ERROR, handleParserError);
parser.parseTextAsync(shipOBJ);
private function handleParserError(e:LoaderEvent):void
{
trace("OBJParser error: ");
trace("OBJParser error: \n" + e.message);
}
private function handleParserComplete(e:LoaderEvent) : void
{
var obj:ObjectContainer3D = ObjectContainer3D(e.resource);
this.addChild(obj);
for (var i:int = 0; i < obj.numChildren; i++)
{
var mesh:Mesh = Mesh(obj.getChildAt(i));
// Here you can interact with the meshes inside of your OBJ
// to set materials or other stuff...
}
}
