How do I use Unity's OnPlayerConnected method?

Question

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnPlayerConnected.html

using System.Collections;
using System.Collections.Generic;
using UnityEngine.Networking;
using UnityEngine;

public class SendData : MonoBehaviour {

    void OnPlayerConnected (NetworkPlayer player) {
        Debug.Log ("A player connected!");
    }

}

This code, surprisingly, doesn't work!

Expected: The server prints "A player connected!" in the Unity editor debug console.

What happens: Nothing is printed. It doesn't matter if I use print() or Debug.Log().

This script is applied to a standard object in the scene. It has a NetworkIdentity.

I really don't know what else to try. The Unity documentation is very short and gives an example very similar to this. My code should be even simpler than Unity's example but it doesn't work.

OnPlayerConnected() and OnPlayerDisconnected() are part of the old networking API and not UNET what is currently being used. In order to achieve what you want you have to exted the Network Manager. Something like this will get you on the right track :

using UnityEngine.Networking;
using UnityEngine;

public class Send_data : NetworkManager
{

   public override void OnServerConnect(NetworkConnection Conn)
   {
     if (Conn.hostId >= 0)
     {
        Debug.Log("New Player has joined");
     }
    }
}
