Photon Unity Networking (PUN 2)
PUN 2 is a popular cloud-based networking solution developed for Unity. It connects clients via Photon Cloud without requiring the developer to host and manage physical servers.
using Photon.Pun;
public class NetworkLauncher : MonoBehaviourPunCallbacks {
void Start() {
PhotonNetwork.ConnectUsingSettings();
}
}Inheriting from MonoBehaviourPunCallbacks allows you to listen to connection, room creation, and player join events with ease.
Lobby and Room Structure
Upon connecting to Photon Cloud, players first arrive in a Lobby waiting area. To play a match together, players must join a common Room.
// Creating a new room
PhotonNetwork.CreateRoom("Arena_01");
// Joining an existing room
PhotonNetwork.JoinRoom("Arena_01");Players inside the room can see and synchronize each other's avatars in real time using the PhotonView component.
Practice PUN connection status
Define a Start method. Inside, print the text "Photon Cloud baglantisi kuruldu" using Debug.Log.
Starter code
using UnityEngine;
public class PunConnector : MonoBehaviour
{
// Start icinde PUN baglanti durumunu yazdir
}Sample solution
using UnityEngine;
public class PunConnector : MonoBehaviour
{
void Start()
{
Debug.Log("Photon Cloud baglantisi kuruldu");
}
}Expected output
Photon Cloud baglantisi kuruldu
