Hello Guys,

My project loads models with the embed technique:

[Embed(source="/../embeds/tank.obj", mimeType="application/octet-stream")]
private var OBJData : Class; 

The index.html has the javascript code:

[removed]
  var flashvars = {
  };
  var params = {
   menu: "false",
   scale: "noScale",
   allowFullscreen: "true",
   allowScriptAccess: "always",
   bgcolor: "",
   wmode: "direct" // can cause issues with FP settings & webcam
  };
  var attributes = {
   id:"Away3daway3dexamplesbroomstick20a270c"
  };
  swfobject.embedSWF(
   "Away3daway3dexamplesbroomstick20a270c.swf", 
   "altContent", "400px", "320px", "11.0.0", 
   "expressInstall.swf", 
   flashvars, params, attributes);
 [removed] 

My question: how can I link the two together.
So if I want to load the house.obj instead of the tank.obj, and I select the file with a drop-down menu in my site (html), then what should I write in the acrion script. (I assume I should define a variable, which will be equal to the flashvar=“xxxxx”).

hi

in html/js you define your loadvars like this:

var flashvars={};
  flashvars.var_yourvar="youVariableValue"; 

in as3 you get your var like this:

if (this.loaderInfo.parameters.var_yourvar) {
   trace(this.loaderInfo.parameters.var_yourvar);
 }

Hi,

thanks for the feedback.

But how do I link the variable name into the Embed source?

Just put it into the source line? ... but then it will think that’s the name of the file, and it’s not a variable:

[Embed(source="/../embeds/adria/my_variable.obj", mimeType="application/octet-stream")]
private var OBJData : Class;

hi

i think your problem is this:

you want a model-viewer where the html loads a swf and tells it which obj to load.

if you use the [Embed] tag, your swf does not load the obj on runtime, but inserts the obj file into the swf when then swf is created.

so if you would use [Embed] you would have to compile one swf for each obj and than load the different swfs per html/php. i wouldnt do that.

you should pass the obj-file name to the swf.
than you should use the away3d-loader classes to load the obj with the given name.

hope that helps

Thanks 80prozent,

Correct, that’s what I want (a model loader, which loads the .obj files in real-time).

How should I change the code from this:

[Embed(source="/../embeds/tank.obj", mimeType="application/octet-stream")]
private var OBJData : Class; 

any idea?
Thanks for your help!

PS: if this loading issue and flashvar variable forwarding is solved, then my loader is complete…

i didnt test this, but this is how it should work:

AssetLibrary.enableParser(OBJParser);   AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
AssetLibrary.load(new URLRequest("yourObject.obj"));


private function onAssetComplete(event:AssetEvent):void
  {
  if (event.asset.assetType == AssetType.MESH)
   {
    trace("Mesh parsed");
                                //setup materials, apply lights......

}
}
