Hi all,

I'm getting a strange error every time I try to send a score update using an rpc using Photon Unity Networking (And Unity3d).

Here is the Error.

RPC method 'RPC_SendScore(String, Single)' found 2x on object with PhotonView 1201. Only one component should implement it.Return type must be void or IEnumerator (if you enable RunRpcCoroutines).

UnityEngine.Debug:LogErrorFormat (UnityEngine.Object,string,object[])

Photon.Pun.PhotonNetwork:ExecuteRpc (ExitGames.Client.Photon.Hashtable,Photon.Realtime.Player) (at Assets/Photon/PhotonUnityNetworking/Code/PhotonNetworkPart.cs:651)

Photon.Pun.PhotonNetwork:RPC (Photon.Pun.PhotonView,string,Photon.Pun.RpcTarget,Photon.Realtime.Player,bool,object[]) (at Assets/Photon/PhotonUnityNetworking/Code/PhotonNetworkPart.cs:1275)

Photon.Pun.PhotonNetwork:RPC (Photon.Pun.PhotonView,string,Photon.Pun.RpcTarget,bool,object[]) (at Assets/Photon/PhotonUnityNetworking/Code/PhotonNetwork.cs:2847)

Photon.Pun.PhotonView:RPC (string,Photon.Pun.RpcTarget,object[]) (at Assets/Photon/PhotonUnityNetworking/Code/PhotonView.cs:678)

SubHealthManager:SubDeath () (at Assets/_Scripts/PlayerControllers/SubHealthManager.cs:141)

SubHealthManager:TakeDamage (single) (at Assets/_Scripts/PlayerControllers/SubHealthManager.cs:116)

SubHealthManager:ImpactDamage (UnityEngine.Collision) (at Assets/_Scripts/PlayerControllers/SubHealthManager.cs:100)

SubHealthManager:OnCollisionEnter (UnityEngine.Collision) (at Assets/_Scripts/PlayerControllers/SubHealthManager.cs:88)

Here is the section of the code that deals with the 'death' - from TakeDamage(), ImpactDamage() sends variable to TakeDamage() to update the values of the player and supposed to send the information to every other player. (This get's called when the player health hits zero, it works find 'locally')

public void SubDeath()
   {
       float damage = 5f;
       rbGravity.useGravity = true;
       playerControllerMK.SetActive(false);
       playerControllerController.SetActive(false);
       playerFiringController.SetActive(false);
       adjustedOverLoad = (overloadCounter * overloadRecoveryTime);
       isDead = true;
       //ScoringManager.Instance.UpdateScores(teamName, damage);
       if (PV.IsMine)
       {
           Debug.Log("PV Is Mine, I should send S*** now");
           PV.RPC("RPC_SendScore", RpcTarget.All, teamName, damage);
       }
   }

   [PunRPC]
   void RPC_SendScore(string teamName, float damage)
   {
       ScoringManager.Instance.UpdateScores(teamName, damage);
   }

And here is the section of the Score Manager which updates the scores etc. that the RPC is (trying) to send information to.

[

    public void UpdateScores(string teamName, float scoreReceived)
       {
           if(teamName == "SMC Retrieval Team")
           {
               pscScoreCounter -= scoreReceived;
               if (pscScoreCounter <= 0)
               {
                   pscScoreCounter = 0;
               }
               if (pscScoreCounter >= 100)
               {
                   pscScoreCounter = 100;
               }
           }

           if(teamName == "Prehistoric Creatures")
           {
               smcScoreCounter -= scoreReceived;
               if (smcScoreCounter <= 0)
               {
                   smcScoreCounter = 0;
               }
               if (smcScoreCounter >= 100)
               {
                   smcScoreCounter = 100;
               }
           }

           txtSMCScoreCounter.text = smcScoreCounter.ToString();
           smcScoreBar.sizeDelta = new Vector2(smcScoreCounter * scoreBarMultiplier, scoreBarHeight);
           if (smcScoreCounter <= 0)
           {
               WinCondition("Prehistoric Creatures");
           }

           txtPSCScoreCounter.text = pscScoreCounter.ToString();
           pscScoreBar.sizeDelta = new Vector2(pscScoreCounter * scoreBarMultiplier, scoreBarHeight);

           if (pscScoreCounter <= 0)
           {
               WinCondition("SMC Retrieval Team");
           }
       }

]

I'm not really sure what's going on, but based on the error, it seems as though PUN is saying that there are two objects trying to trigger the same RPC at the same time? (not entirely sure sure though).

I get the error when there is just one player in the game as well as multiple.

Could anyone shed some light please?

Thanks
Spud

This looks similar to https://forum.photonengine.com/discussion/14626/rpc-problem-with-photonviews

Even if it's not, you should ask in that forum as it's more likely to have fellow developers there.

I received a message with your comment text but it's not in the forum. Can you link to your question in the Photon forum?

What I read here and there tells me it's not just code in play but where you attach scripts and responders to the object(s).

Hi Sorry,

Not been here for a while and compeltely missed the reply button at the bottom. lol.

The post I made over on the photon forum is literally exactly the same as this one. Tis a little baffling (especially as I can't find the error posted anywhere else. :-/

Seems not only can there be what issue in the first link but you can add the same component twice and get the same error.

Remember I'm not there to check this out. Hope someone across all the forums gives you new ideas.
