Photon Network RPC Random Range Problem
Hi, I'm working on a project. I'm using this script for bot money;

 using UnityEngine;  
 using System.Collections;  
   
 public class Botmoney : MonoBehaviour {  
     public int BotMoney;  
     public bool botStealable = true;  
     PhotonView photonView;   
     // Use this for initialization  
     void Start () {  
         photonView = GetComponent ();  
         photonView.RPC ("RandomMoneyFBot", PhotonTargets.All);  
           
     }  
     [RPC]  
     void RandomMoneyFBot(){  
         BotMoney = Random.Range (12,60);  
     }  
 }  
 

But every client gets diffrent numbers. How I can solve this?

Also;

When I want RPC to a string with PhotonNetwork.playerName every player gets their own player name. I want to just write RPC sender's name to string. How can I do this?

The RPC is sended to all Clients and the Content of the RPC is executed on all Clients, this means the Random.Range result is on all Clients a different.

A better approach is to generate a Random Number on one Client and send this Number to all other clients.

Same Answer for the other Topics you opened.

I dont get the second Question but, it is the same problem and same approach to solve ur problem.

I changed your code to represent what you wanted if I understood right:

using UnityEngine;
using System.Collections;

public class Botmoney : MonoBehaviour {

      public int BotMoney;

      public bool botStealable = true;

      PhotonView photonView; 

      private void Start ()   
      {  
              photonView = GetComponent();

              int randomMoney = Random.Range (12, 60);

              photonView.RPC ("ReceiveRandomMoneyFromBot", PhotonTargets.All, randomMoney);  
      }

      [RPC]  
      private void ReceiveRandomMoneyFromBot(int moneyAmount)  
      {  
             BotMoney = moneyAmount;  
      }  
}

So basically, what happens now is the random money amount is created before we send the RPC to all clients and we send the random amount as a parameter to all players, which means that the number for everybody will be equal to the amount that was created by the client who sent the RPC.

I am getting different numbers on each clients. How can i solve this

bujt wouldnt this code (int randomMoney= ...) get executed on ALL clients because it's in a start method ? where do we specify that the code should ONLY be run on 1 client ? and then the result sent to all .... ?

should we maybe use the List of Players and make the random generation happen only in Player[0] for example, or a way to choose the Master Client ?

You could also just use the same seed on all clients, then all clients should generate the same random numbers.

var seed = 12532434; //some custom made seed that must be the same on all clients, use what ever is available for all clients and is the same  
var rnd = new Random(seed);  
var rndValue = rnd.Next(0, 10);

Now if all clients call rnd.Next(0,10) the first time it generates 4, next time it generates a 2, then a 6,9...
of course all clients have to call the rnd.Next the same amount
