Mirror - Authority issues

Community Showcases

I have been trying to learn how to use mirror to make a simple chat. I have been running into authority issues for the command. My script is the same as the tutorial but it is a bit a old.

I have a networkmanger on one object and a network identity and this script on another

using System.Collections;
using System.Collections.Generic;
using System;
using UnityEngine;
using Mirror;
using TMPro;

public class Chat : NetworkBehaviour
{
    public TMP_Text textOutPut;
    public TMP_InputField inputText;
    private static event Action<string> OnMessage;

    public override void OnStartAuthority()
    {

        OnMessage += HandleNewMessage;
    }

    [ClientCallback]
    private void OnDestroy()
    {
        if (!hasAuthority) { return; }

        OnMessage -= HandleNewMessage;
    }

    private void HandleNewMessage(string message)
    {
        Debug.Log("recieve message");
        textOutPut.text += message;
    }

    [Client]
    public void Send(string message)
    {

        if (string.IsNullOrWhiteSpace(message)) { return; }
        if(hasAuthority)
            CmdSendMessage(message);

    
    }

    [Client]
    public void Send()
    {
        Debug.Log("calling send");
        if (string.IsNullOrWhiteSpace(inputText.text)) { return; }

        //if(hasAuthority)
        //    CmdSendMessage(inputText.text);
        CmdSendMessage(inputText.text);

        inputText.text = string.Empty;
    }

    [Command]
    private void CmdSendMessage(string message)
    {
        Debug.Log("calling cmd");
        RpcHandleMessage($"[{connectionToClient.connectionId}]: {message}");
    }

    [ClientRpc]
    private void RpcHandleMessage(string message)
    {
        Debug.Log("calling rpc");
        OnMessage?.Invoke($"\n{message}");
    }
}

I gather I don’t have the authority to call CmdSendMessage but I don’t how I should be doing this properly/how to fix the error.

I tried using if(hasauthority) but then it gives me no error but doesn’t call the command.

I think some of my issues stem from the player object this is attached to not being spawned by the network manager. Now that I have changed it to do that it kind of works and the last connected client can send to themselves but not to anyone else. If I connect another client they get that power.

One more edit. I have figured the last connected client ends up with authority. I don’t know how to give authority back to the previously connected clients I think it my problem.

It works if i replace [command] with [Command(ignoreAuthority = true)] but I assume that isn’t how you are meant to do it!

any tips on how to do this properly? I feel using [Command(ignoreAuthority = true)] is a really bad idea.

I would love to know how to do it properly.
