No easy way to clone COLLADA models

[statico]

If I include a COLLADA model in my XML, say the rubber duckie sample:

<collada document="duck.dae" /> 

There doesn't seem to be a way of adding an arbitrary number of ducks to the scene graph.

I've tried creating a new GLGE.Object and setting its mesh and materials, but calling doc.getElement on the document's onLoad handler results in a GLGE.Collada object that is uninitialized -- it's missing the xml property and its children array is empty.

I found that GLGE.Collada supports callbacks when finished. This might work:

  var assetFinished = (function() {
    var NUM_ASSETS = 2;
    var count = 0;
    return function() {
      if (++count == NUM_ASSETS) init();
    };
  })();

  var duck = new GLGE.Collada();
  duck.setDocument('assets/duck.dae', null, assetFinished);

  doc = new GLGE.Document();
  doc.onLoad = assetFinished;
  doc.parseScript('scene-xml');

  function init() {
    var renderer = new GLGE.Renderer($('canvas')[0]);
    ...
  }

Yep, my custom asset loader works. I also have this function:

    function createDuckie() {
      if (!duck.xml) throw new Error("Collada model not loaded");
      var source = duck.getObjects()[0]; // Ew.
      var dest = new GLGE.Object();
      dest.setScale(0.01);
      dest.setRotX(Math.PI / 2);
      dest.setRotY(Math.random() * 2 * Math.PI);
      dest.setMesh(source.getMesh());
      dest.setMaterial(source.getMaterial());
      return dest;
    }
