Sometimes,WWW class doesn't work!!!

Unity Engine
1

My code is

public class www : WWW
{
    public www(string url):base(url){}
    private bool _Used = false;
    public bool Used
    {
        set
        {
            _Used = value;
        }
        get
        {
            return _Used;
        }
    }
}

    private static IEnumerator _LoadBytes(string url, Action<string> GetString, Action<byte[]> GetBytes)
    {
        www rerquest = new www(url);
        BackGroundEntry.debug += "_LoadBytes:" + url + "\n";
        if (enable)
        {
            proList.Add(rerquest);
        }
        BackGroundEntry.debug += "_LoadBytes:1\n";
        yield return rerquest;
        BackGroundEntry.debug += "_LoadBytes:2\n";
        try
        {
            BackGroundEntry.debug += "_LoadBytes:" + rerquest.error+ "\n";
            if (rerquest.isDone)
            {
                if (GetBytes != null)
                {
                    BackGroundEntry.debug += "_LoadBytes:4\n";
                    GetBytes(rerquest.bytes);
                }
                if (GetString != null)
                {
                    BackGroundEntry.debug += "_LoadBytes:5\n";
                    BackGroundEntry.debug += "_LoadBytes:length:" + rerquest.bytes.Length + "\n";
                    BackGroundEntry.debug += "_LoadBytes:" + rerquest.data + "\n";
                    GetString(rerquest.data);
                }
            }
        }
        catch (Exception e) { }
        finally
        {
            rerquest.Used = true;
            if (!enable)
            {
                rerquest.Dispose();
                rerquest = null;
            }
        }
    }

It works well in edit mode,but I publish it as a web app, sometimes it doesn’t work,"rerquest.bytes.Length " is 0. Any solution?

I think you need paste more code. :wink:

I resolved this problem, because of thread permission. If anybody has the same problem, try invoke function!
