Instatiation problems with photon
Hi, i am learning unity3d with usage of Photon and got to a problem where PhotonNetwork. 2player connect then instatial 3 object so how can i solved it.please help me.
here my code: using UnityEngine; using System.Collections.Generic; using System.Collections; using UnityEngine.SceneManagement; using System.IO;
public class NetworkManagersite :MonoBehaviour {
public bool spawn = false;
private int maxPlayer = 1;

int maxChatMessages = 5;
private string maxPlayerString ="2";
public string Version = "Version 1";
private Vector3 up;
private Vector2 scrollPosition;
public static NetworkManagersite inst;
private PhotonView PhotonView;

Hi,
if I'm not mistaken, the RPC to create the player is called twice on the MasterClient and once on the remote client, which is caused by multiple unwanted RPC calls from OnSceneFinishedLoading callback. Please try another option for synchronizing the current scene instead of sending RPCs. Therefore you can set PhotonNetwork.automaticallySyncScene = true;
which automatically synchronizes the active scene whenever the MasterClient uses PhotonNetwork.LoadLevel(...);
. To instantiate objects, you can for example use the OnJoinedRoom()
callback. If this doesn't work because you are loading another scene after the client has joined the room, you can also use MasterClient to send a RPC or raise an event to notify all clients, to instantiate their objects.
How can I get rid of that multiple spawning by a client when he leaves and rejoins the room.
You can for example create a boolean which is set to true, if the client has created his player object. When you later rejoin the game, you can check that value and continue related to whatever the value describes.
