Third Party Photon RPC does not work

Hello, beginner question but I do not understand. I get the ...not set to an instance of an object...error for the line

view.RPC("TakeTimeDamageRPC", RpcTarget.All);

I know what that in theory means but I have no idea why this happens. So here is the simple script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using Photon.Pun;
6.  
7. public class Timer : MonoBehaviour
8. {
9.     public float time = 60;
10.     public Text timeDisplay;
11.     PhotonView view;
12.  
13.     public void TimeDamage()
14.     {
15.         view.RPC("TakeTimeDamageRPC", RpcTarget.All);
16.     }
17.  
18.  
19.     [PunRPC]
20.     void TakeTimeDamageRPC()
21.     {
22.         time -= 1 * Time.deltaTime;
23.         timeDisplay.text = time.ToString();
24.     }
25.  
26.     void Update()
27.     {
28.         TimeDamage();
29.     }
30. }

And here are Screenshots how it looks (Time Text is just a text on a Canvas) - so why is it not set to the instance of an object ?

 

To me, this looks as if view is never set properly. Have a look at MonoBehaviourPun and set the view, or inherit from MonoBehaviourPun and use this.photonView to call the RPC.

 

Thank you, that worked perfectly.

 

One question I I can, it seems like time.deltatime is not working properly or at least the time is much faster then it shoud? But from what I see, it is used also for Photon?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using Photon.Pun;
6.  
7. public class Timer : MonoBehaviourPun
8. {
9.     public float time = 60f;
10.     public Text timeDisplay;
11.     PhotonView view;
12.     GameMaster gmaster;
13.  
14.  
15.     public void TimeDamage()
16.     {
17.         gmaster = FindObjectOfType<GameMaster>();
18.         this.photonView.RPC("TakeTimeDamageRPC", RpcTarget.All);
19.     }
20.    
21.     void Start()
22.     {
23.  
24.     }
25.  
26.     [PunRPC]
27.     void TakeTimeDamageRPC()
28.     {
29.         time -= 1 * Time.deltaTime;
30.         timeDisplay.text = time.ToString("F0");
31.  
32.         if (time <= 0)
33.         {
34.             time = 0;
35.         }
36.  
37.         if (time <= 1)
38.         {
39.             gmaster.source.Play();
40.             gmaster.EndTurn();
41.             time = 60f;
42.         }
43.  
44.     }
45. }
46.  

Code is then called in the update in another script...

 

Time.deltaTime is a value from Unity. It tells you how much time passed since the last Update() call by the engine.
What are you expecting?

 

Before using Photon - so in one client only and only with Unity code - the countdown counted in seconds. Now that I moved everything to MP, it's much faster, and that does not only look a bit stupid, at least when using a build and the unity game scene it gets asynchron pretty fast, so I am not sure how to set it back to exactly 1 second

 

Not knowing your project, it's a bit hard to help.
I noticed that the RPC method is not a Coroutine. It will be called once via the photonView.RPC() and that's it.

 

of course, I understand! I just noticied something odd - when I just a room and start the game, the time counts down normally. but when I open a room and join in both with a standalone client and in unity, it gets faster. I would suppose I call everything...2 times and would nee something like an onhostonly?

 

that of course didnt work - or it did but then only worked on the master client and nothing happened on the other client, lol

I am not sure about the coroutine - I think the problem is that the countdown counts normal (1 second at a time) when I only connect one player, but then gets faster when the second player joins (I would suppose it gets double as fast). so I think the solution would be calling it for both master client and second client, but then it should only "run" on the master client but also synching on the other...oh man

 

Instead of counting down time by subtracting using

Time.deltaTime

, set a

timerStartTime

to

Time.time

at the beginning, and then use

countDownDuration - (Time.time - timerStartTime)

to calculate how much time is left.

timeLeft = countDownDuration - (Time.time - timerStartTime);
