Questions & Answers

Hey guys the GUI Buttons are not Displaying in the currently creating a Test Game, I am a current Newbie at using Unity and a C#, C++ Programmer whois just learning the Documentation. Here is the Code in C#

using UnityEngine;
using System.Collections;


public class Pause_Menu : MonoBehaviour
{
    bool paused = false;

    void Update()
    {
        if (Input.GetButtonDown("Pause"))
        {
            if (!paused)
            {
                Time.timeScale = 0;
                paused = true;
            }
            else
            {
                Time.timeScale = 1;
                paused = false;
                OnGui();
            }
        }

    }

    void OnGui()
    {
        if (paused)
        {
            if (GUI.Button(new Rect(10, 50, 100, 30), "Resume"))
            {
                Time.timeScale = 1.0f;
                paused = false;
            }
            if (GUI.Button(new Rect(10, 90, 100, 30), "options"))
            {
            }
            if (GUI.Button(new Rect(10, 130, 100, 30), "Quit"))
            {
            }
        }
    }
}

The Game Pauses Correctly the Buttons are not showing up when I it Pauses though

The function name is OnGUI() so OnGui() will not work.
