I have moved to using the AssetLibrary for reasons like all that
above. Here's what I'd do:
AssetLibrary.enableParser(OBJParser);
AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE,
onAssetRetrieved);
AssetLibrary.addEventListener(LoaderEvent.RESOURCE_COMPLETE,
onResourceComplete);
AssetLibrary.load(new treedata()); // classes should be capitalized
btw
then name your stuff in the onAssetRetrieved function:
function onAssetRetrieved(event:AssetEvent) : void {
trace(event.asset.assetType);
if (event.asset.assetType == AssetType.MESH) event.asset.name =
"treeMesh";
if (event.asset.assetType == AssetType.BITMAP) event.asset.name =
"treeBitmap"; // for a model that loads a texture file
}
then when everything has been parsed completely
function onResourceComplete(event:LoaderEvent):void {
var mesh:Mesh = AssetLibrary.getAsset("treeMesh") as Mesh;
var treematerial:BitmapMaterial = new BitmapMaterial(new
treeimage().bitmapData,true);
mesh.material = treematerial;
}
I think it's way cleaner than all that weird for loop stuff and you
can access stuff in the library whenever you need to. Also, not sure
if you are declaring variables the way you show above, but typing them
when you declare helps a lot in debugging.
