Can't send certain floats.

Postby Birch » 12 Jul 2012, 09:42

Hello!

I've got a really strange problem, i am trying to do a really simple thing, put a float in a SFSObject and sending it to the server.

This code works:

Code: Select all


   void test(){
      
      SFSObject data = new SFSObject();
      
      data.PutFloat("x", 2.305684f);
      
      smartfox.Send(new ExtensionRequest("moveRequest", data, MainSmartfox.smartfox.LastJoinedRoom, false));            
      
   }         



This code doesn't work:

Code: Select all


   void test(){
      
      SFSObject data = new SFSObject();
      
      data.PutFloat("x", 1.305684f);
      
      smartfox.Send(new ExtensionRequest("moveRequest", data, smartfox.LastJoinedRoom, false));            
      
   }



The only thing i changed was that i increased the float with 1, and suddenly it works! I am have absolutely no clue whats going on and all help is appreciated!

These floats doesn't work either:
1.305684
-1.448122
1.258205
2.796537

The error message in the smartfox console:

Code: Select all

Hi,
1) Which Server version are you using?
2) Does the problem happen without using the BlueBox connetion? Maybe there's a relation.

thanks

I am using SFS2X 2.0.1, and setting useBluebox to false doesn't change anything.

Please do me a favour. Install the latest patch (it won't require a new full installation) then run your test again and without connecting to the BlueBox. I need this in order to see where the problem is with a direct connection.
Thanks

Btw, as a workaround, have you tried using a double instead? Does it work?

Can you try what I have suggested and post the result here? Also there's a new release of the C# API. We need to make sure that the problem is present in the current version.
Thanks

I downloaded the latest patch and C# api and turned off bluebox, and now it works, but without bluebox i still get the same error. I've also noticed (when using bluebox) that if i convert the floats to double, i can send them. But then there're other numbers that won't work.

Can't send as float:
1.305684
-1.448122
1.258205
2.796537

Can't send as double:
-0.09495857f
0.08546299
-1.93716
1.880184
3.124145

I don't follow:
you say you turned off the BBox and it works. Then you go on saying that without Bluebox you still get the error. Which one is correct?

Thanks. I have tested using Flash and the problem is not reproducible, so I would be inclined to think that this is a C# specific issue.
I will ask Thomas Lund to look into it.

Stay tuned for an update soon.
Cheers

Very weird.

I've made a small test case as well and cannot! reproduce.

Code: Select all

         ISFSObject args = new SFSObject();
         args.PutFloat("x", 1.305684f);
         
/*         1.305684
-1.448122
1.258205
2.796537
                   */
         
         sfs1.Send(new ExtensionRequest("TestCmd", args, sfs1.LastJoinedRoom));


Sends all numbers perfectly fine over bluebox. Server even returns it and I print the number. See output below.

Could you try to run your testcode with debug enabled and grab the packet dump similar to mine?

If you set debug flag to true on your connection, they will appear in the Unity editor.log/player.log
