Invalid cast exception between WebGL and Mobile builds !

Postby faisal007 » 02 Mar 2017, 16:24

Hi,

We Recently started porting our unity game from WebGL to mobile. This mostly consisted of UI changes and no changes to the SFS code were made, however we started encountering weird cast errors right away in the client side code.

Code: Select all

InvalidCastException: Cannot cast from source type to destination type.
Sfs2X.Entities.Variables.BaseVariable.GetIntValue ()
BuddyListController.OnBuddyVariablesUpdate (Sfs2X.Core.BaseEvent evt) (at Assets/Scripts/UIScripts/BuddyListController.cs:116)



The Client Side code is as follows:

Code: Select all

private void OnBuddyOnlineUpdate(BaseEvent evt)
    {
        bool isItMe = (bool)evt.Params["isItMe"];
        Buddy buddy = (Buddy)evt.Params["buddy"];

        if (!isItMe)
        {
            if (buddy.IsOnline)
            {
                Debug.Log(buddy.GetVariable("$userID").Type);
                int buddyID = buddy.GetVariable("$userID").GetIntValue();
}
}}


Server side code is:

Code: Select all

buddyVars.add(new SFSBuddyVariable("$userID", res.getSFSObject(i).getLong("user_id").doubleValue()));


the cast error happens when buddy.GetVariable("$userID").GetIntValue(); line is run. this is really confusing since this is working code in the WebGL Build. This is happening in a large amount of places in the code base.

Hi,
can you please specify which API version you're using and SFS2X version as well?

Thanks
Lapo

2.9 is almost 3 years old, I would recommend updating the server at least to the latest 2.11.x update, which is only a patch and doesn't require a full install.
http://smartfoxserver.com/download/sfs2x#p=updates
(see bottom of page)

The reason being that we've fixed a couple of issues related with type conversions for webgl.
If the problem persists let us know.

Cheers
Lapo
