Photon PUN2, Rpc score can't correctly.

Question

Hi all , I have two ways now. But they can't send correct. I'm very confuse.

I want MasterClient send score to the other client ,and the other client send score to MasterClient.

Way1: It looks have no wrong, but it can't work

     [PunRPC]
     void MasterCount()
     {
             masterCount = gameCon.playerScore;
     }
 
     [PunRPC]
     void OtherCount()
     {
             otherCount = gameCon.playerScore;
     }
 
     void Update()
     {
        
         if(PhotonNetwork.IsMasterClient)
         {
             if (gameObject.GetComponent<PhotonView>().IsMine)
             {
                 if (gameCon.isClickButton)
                 {
                     masterCount = gameCon.playerScore;
                     scoreText.text = Mathf.Floor(masterCount).ToString("0");
                     gameObject.GetComponent<PhotonView>().RPC("MasterCount", RpcTarget.Others);
                 }
             }
         }
         else
         {
             if (gameObject.GetComponent<PhotonView>().IsMine)
             {
                 if (gameCon.isClickButton)
                 {
                     otherCount = gameCon.playerScore;
                     scoreText.text = Mathf.Floor(otherCount).ToString("0");
                     gameObject.GetComponent<PhotonView>().RPC("OtherCount", RpcTarget.Others);
                     
                 }
             }
         }
     }

Way2: I change the RPC , it looks very weird . The other can send othercount to Master , and Master still can't send .

 [PunRPC]
      void MasterCount()
      {
              masterCount = gameCon.playerScore;
      }
  
      [PunRPC]
      void OtherCount()
      {
              otherCount = gameCon.playerScore;
      }
  
      void Update()
      {
         
          if(PhotonNetwork.IsMasterClient)
          {
              if (gameObject.GetComponent<PhotonView>().IsMine)
              {
                  if (gameCon.isClickButton)
                  {
                      masterCount = gameCon.playerScore;
                      scoreText.text = Mathf.Floor(masterCount).ToString("0");
                      gameObject.GetComponent<PhotonView>().RPC("OtherCount", RpcTarget.Others);
                  }
              }
          }
          else
          {
              if (gameObject.GetComponent<PhotonView>().IsMine)
              {
                  if (gameCon.isClickButton)
                  {
                      otherCount = gameCon.playerScore;
                      scoreText.text = Mathf.Floor(otherCount).ToString("0");
                      gameObject.GetComponent<PhotonView>().RPC("MasterCount", RpcTarget.Others);
                     
                  }
              }
          }
      }

Hey there,

you really have to learn to understand the documentation of photon... This is a really basic mistake you do there...

A RPC like any other function needs arguments you actually pass. Your current functions never transfer any data.

Let me put it like this: you have this function:

   [PunRPC]
   void OtherCount()
   {
           otherCount = gameCon.playerScore;
   }

then when you call

  photonView.RPC("OtherCount", RPCTarget.Others);

at player A; then there will only be a message outgoing from player A to call this function at all other players. Which means that player B will call OtherCount with values that are set in his own instance.

To actually send Data you need arguments:

   [PunRPC]
   void OtherCount(int count)
   {
          //do something with the value "count" here
   }

where you then can call

 photonView.RPC("OtherCount", RPCTarget.Others, valueYouWantToTransferToOtherPlayers);

Please read the documentation!
