Unity delay in sending the current value when using sockets

Question

The client.cs in Visual Studio.

private void SendToServer(string HeartRate)
    {
        SetHRTest(HeartRate);
        try
        {
            s = client.         


        

Answer 1

You are starting and shutting down the streams at every frame. Move your s, sr and sw initializations to the Start method and use OnApplicationQuit for closing.

void OnApplicationQuit()
{
   s.Close();
   soc.Close();
}

Doing so Unity will still hang as ReadLine is not asynchronous and will lock the execution until your socket receives data.

First two ways I can think of to go around this are:

• using threads
• using async callbacks (which I do in my UDP servers in Unity 3D). See this question: What is AsyncCallback?

Answer 2

I think it's the fact that you put all the server stuff in the Update. Which means it'll get called every frame. Which is a lot.

You should probably put all this in a separate method and call that from the client.
