How to send a message or event into Server Unity3D? - unity3d

Question

I am learning about Networking in Unity. I am confused on how can I send a message or event from client to server. I have these script already that successfully connect my client to server.
This is my server script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
public class ServerNetwork : MonoBehaviour {
void Start()
{
SetupServer();
}
// Create a server and listen on a port
public void SetupServer()
{
NetworkServer.Listen(4444);
NetworkServer.RegisterHandler(MsgType.Connect, OnClientConnected);
Debug.Log("Server is running");
}
void OnClientConnected(NetworkMessage netMsg)
{
Debug.Log("Client connected");
Debug.Log(netMsg.msgType);
}
}
This is my client Script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
public class ClientNetwork : MonoBehaviour {
NetworkClient myClient;
public bool isClientConnected = false;
void Start()
{
SetupClient();
}
// Create a client and connect to the server port
public void SetupClient()
{
myClient = new NetworkClient();
myClient.RegisterHandler(MsgType.Connect, OnConnected);
myClient.Connect("127.0.0.1", 4444);
isClientConnected = true;
}
// client function
public void OnConnected(NetworkMessage netMsg)
{
Debug.Log("Connected to server");
}
}
The Server Script is attached to "NetworkManager" Object on ServerScene
The Client Script is attached to "NetworkManager" Object on ClientScene
I have build ClientScene alone to run as a client, and running ServerScene inside editor
With these script, I can already connect the client into the server. From this, how can I communicate from client to server ?
the purpose here is to send real time score into the server from client every second.
Thank You

You have to use [SyncVars] Attribute. In short what it does is it synchronize a variable from client to the server. Here is a simple example from Unity3d Documentation.
[SyncVar]
int health;
public void TakeDamage(int amount)
{
if (!isServer)
return;
health -= amount;
}
another way to do this is by using custom WebSocket implementation for Unity3D. There a few very good ones in GitHub.Also please take a look at the documentation Unity3d
