Hello,
Up to now I made an model viewer, which loads an object file and a texture.
I was using embed, but as I want to have the loading real-time, I need to load loader3D, or loaderAsset.
My aim is to give the filename of the object and the texture through flashvar, and then I can define in .php, which object and textures I want to load.—> then the swf file loads them.
Problems:
- how can I use the loader3D instead of Embed?
- how should I insert my variables (name of the object and the texture) into the .as code?
This is the actual code, which I should change somehow

}
private function onEnterFrame(ev : Event) : void
{
_loader.rotationY = -1 * (stage.mouseX - stage.stageWidth / 2);
_view.render();
}
}
}
I tried to implement this:
loader = new Loader3D();
loader.load(new URLRequest("url"), assetLoaderContext);
... but I don’t know how to link it to the OBJData variable. Or even the other parts of the code (for example the parsing) should be changed?
Thanks for your help in advance!
