How do I make a RPC Chat

AutTheWizard

I have been trying to figure this out for a long time now but I am still a complete noob when it comes to photon, how would I make it so when you chat it uses RPC to chat for everyone

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;
using Photon.Pun;

public class GameManager : MonoBehaviour
{
    public int maxMessages = 25;
    public InputField chatBox;

    public GameObject chatPanel, textObject;

    [SerializeField]
    List<Message> messageList = new List<Message>();

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Return))
        {
            if (chatBox.text != "")
            {
                SendMessageToChat(PhotonNetwork.NickName + ": " + chatBox.text);
                chatBox.text = "";
                EventSystem.current.SetSelectedGameObject(null);

            }
            else
            {
                if (!EventSystem.current.currentSelectedGameObject == chatBox.gameObject)
                {
                    chatBox.ActivateInputField();
                }
                else
                {
                    EventSystem.current.SetSelectedGameObject(null);
                }
            }
        }
    }

    public void SendMessageToChat(string text)
    {
        if (messageList.Count >= maxMessages)
        {
            messageList.Remove(messageList[0]);
        }

        Message newMessage = new Message();

        newMessage.text = text;

        GameObject newText = Instantiate(textObject, chatPanel.transform);

        newMessage.textObject = newText.GetComponent<Text>();

        newMessage.textObject.text = newMessage.text;

        messageList.Add(newMessage);
    }
}

[System.Serializable]
public class Message
{
    public string text;
    public Text textObject;
}

Is there anyone who can please help me with this? I have been working on it for a very long time now and I can't figure it out.

You should indicate which PUN you are using. Your example doesn't work with PUN2. Use the example provided with this package PUN2.

AutTheWizard

What do you mean by that? I am using PUN2, but I don't know what you mean by "Use the example provided with this package PUN2"

Klaus Eiperle

I see... they have removed the Chat example. The old PUN Chat example has to be changed for working with PUN2.
You need this in the headline: using Photon.Realtime;

And the script should be a child of Photon. Mine is this:
public class NetworkInRoomChat : Photon.Pun.MonoBehaviourPun

Then you should read the RPC instructions in the PUN2 manual and you are done.

I would not read the input lines in the Update task. Why you don't send the RPC commands by a function like this:
void OnEndEditInputField(InputField _val) {
if (_val.text == "") return;
this.photonView.RPC("Chat", RpcTarget.All, _val.text);
}
