yield statment

I'm trying the MeshSerializer package from the Unity Wiki and it's failing because it's trying to access data that hasn't been downloaded yet.

Looking at the code I can see there should be a yield statement in there:

Code (csharp):

1.  
2. static function ReadMeshFromUrl( url : String ) : Mesh
3. {
4.     var download = WWW(url);
5.     yield download;
6.     if( download.error )
7.     {
8.         print ("Error downloading mesh from " + url);
9.         return null;
10.     }
11.    
12.     var data = download.data;
13.  

However when this is compiled I get a :
error BCE0101: The return type of a generator must be either 'System.Collections.IEnumerable' or 'Object'.

My code matched the use of yield in the Unity documentation example - what am I doing wrong?

 

I believe due to the way coroutines work internally, you can't make them a static method. Try removing "static" and making that class a singleton.

It would be great to file a bug on this so at the very least a better compiler error message can be given.
