Unity Engine

Hello fellow developers

Im running into a few errors. I am trying to write a console for my game. I followed a youtube tutorial

I have to remove override from public override string cName { get; protected set; } and other variables to get anything to work then I start to get this error.

Assets/Scripts/Console/CommandQuit.cs(7,15): error CS0534: InGameConsole.CommandQuit' does not implement inherited abstract member InGameConsole.ConsoleCommand.cName.get

CommandQuit.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

namespace InGameConsole
{
    public class CommandQuit : ConsoleCommand
    {
        public override string cName { get; protected set; }
        public override string cCommand { get; protected set; }
        public override string cDescription { get; protected set; }
        public override string cHelp { get; protected set; }

        public CommandQuit()
        {
            cName = "Quit";
            cCommand = "quit";
            cDescription = "Quits the application";
            cHelp = "Use this command with no arguments to force Unity to quit!";

            AddCommandToConsole();
        }

        public override void RunCommand()
        {
            if (Application.isEditor)
            {
                #if UNITY_EDITOR
                UnityEditor.EditorApplication.isPlaying = false;
                #endif
            }
            else
            {

            }
        }

What do you mean “to get anything to work”? The posted code compiles, so what is the error you get with it?

You may want to look into abstract, but the simple answer is you must override and implement the abstract stuff when you inherit from that class.

umm so unity is very odd. So all i did to fix this is delete and re-typed override on the public variables. and its working now… smh WHAT!!

When override was in the public variables originally it would give a error saying it was not suitable or something to that effect. so i removed it from the declaration which seamed to make it not give that error but threw the error that was in my original post… idk its working now so im not going to question it. lol

public override string cName { get; protected set; }
public override string cCommand { get; protected set; }
public override string cDescription { get; protected set; }
public override string cHelp { get; protected set; }
