Need help with UDP connection:receive problem

[iamrasputin]

I've been working on my multiplayer game and stuck on the moment when I decided to put packet reception of the client into 'main.lua', so i don't have to call it in every object that somehow interacts with the server. I have a stage called 'hub.lua' where the connection:receive was called only once (before I moved it) to approve the connection to the server. If approval was received, the stage changed to 'Stage.lua', where the game itself was supposed to be happening. In 'Stage' I have to update multiple items that require multiple connection:receive calls.
So here's what is happening:
If I run the code and the packet reception is only in 'hub.lua', then everything is working just fine, but if I add the packet reception code to the 'chat.lua' (which is first called in 'Stage.lua') for example, the game freezes with no crash reports. The same happens if I remove packet reception code from both 'chat' and 'hub' and place it in the 'main.lua', which lead me to a conclusion that the problem is caused by call of connection:receive.
The problem is definitely is not on the server side as I have checked all packets that are being sent to the client.
Here's the code:
"hub.lua" (somewhere in the 'hub.update' function) :

Code: Select all

 if _t > _updaterate then
      repeat
        _data = _udp:receive() --data receive problem. Possible leak
        if _data ~= nil then
          _currentCmd, _currentAnws = _data:match("^(%S*) (%S*)")
          _data = nil
        end
      until not _data
      _t = _t - _updaterate
    end

        if _currentCmd == "anwser" then
        _status = _currentAnws
        _currentCmd = nil
          if tonumber(_status) == 1 then
            gotoRoom("Stage")
          elseif tonumber(_status) == 0 then
            _udp:close()
            _udp = Socket.udp()
            connectBtn:setData(connectBtn, 0)
            _status = "No slots available for this address or a connection with your address was not closed" --change to receive error
          end
        end

'main.lua' :

Code: Select all

function love.update(dt)

  _t = _t + dt

  if _udp ~= nil then
    if _t > _updaterate then
      repeat
      local  _data, msg = _udp:receive() --data receive problem. Possible leak
        if _data then
          _currentCmd, _currentAnws = _data:match("^(%S*) (%S*)")
          _data = nil
        end
      until not _data
      _t = _t - _updaterate
    end
  end

  camera:update(dt)
  uMouse:update(dt)


  if current_room then
     current_room:update(dt)
   end

end

Any ideas on what might be wrong?
