Question by shavais · Oct 02, 2021 at 07:27 PM · error messageuser interfaceapplication.quit

Is there a simple way to display an error message?

There doesn't seem to be any simple way to display an error message to the user.

If I Debug.LogError(msg); and then Application.Quit(); the user thinks the program just suddenly crashed for no apparent reason? Lol.

Searching doesn't even show anyone else asking this question. I can't believe it's not a super common need? I guess I'll have to do some custom thing.

What do you all do about the need for this?

Yes, you'll need a custom solution.

Here is a simple and not recommended one (`OnGUI` should not be used for multiple reasons):

 using UnityEngine;
 
 public class ErrorPresenter : MonoBehaviour
 {
     private static ErrorPresenter _instance;
     private string _message;
 
     private static ErrorPresenter Instance
     {
         get
         {
             if(_instance == null)
             {
                 _instance = new GameObject(nameof(ErrorPresenter)).AddComponent<ErrorPresenter>();
             }
 
             return _instance;
         }
     }
 
     public static void Show(string message)
     {
         Instance._message = message;
     }
 
     private void OnGUI()
     {
         if(!string.IsNullOrWhiteSpace(_message))
         {
             Rect container = new Rect(Screen.width * 0.3f, Screen.height * 0.3f, Screen.width * 0.4f, Screen.height * 0.4f);
             GUI.Box(container, (string) null);
             GUILayout.BeginArea(new RectOffset(20, 20, 20, 20).Remove(container));
 
             DrawLabel();
             DrawButton();
 
             GUILayout.EndArea();
         }
     }
 
     private void DrawLabel()
     {
         GUILayout.FlexibleSpace();
         GUILayout.BeginHorizontal(GUILayout.ExpandWidth(true));
         GUILayout.FlexibleSpace();
         GUILayout.Label(_message);
         GUILayout.FlexibleSpace();
         GUILayout.EndHorizontal();
         GUILayout.FlexibleSpace();
     }
 
     private static void DrawButton()
     {
         GUILayout.BeginHorizontal(GUILayout.ExpandWidth(true));
         GUILayout.FlexibleSpace();
         if (GUILayout.Button("Quit", GUILayout.MaxWidth(Screen.width * 0.1f)))
 #if UNITY_EDITOR
             UnityEditor.EditorApplication.ExitPlaymode();
 #else
                 Application.Quit();
 #endif
         GUILayout.FlexibleSpace();
         GUILayout.EndHorizontal();
     }
 }

And call ErrorPresenter.Show("My error message"); wherever and whenever you want.


I advise you building a simple canvas with Text & Buttons instead.

Thank you very much for your answer, which comes with a complete solution, if a bit outdated. I guess I'll build a canvas based solution, as you suggest, and post it here for posterity.
