How to make a pause menu in c#?

[matthew_tavares1]

I’m trying to make a pause menu for my game but I don’t really understand how to make the game actually stop, I’ve looked into timescale but I don’t really understand how to make it work. I want it to have buttons that will allow the player to resume the game, look at options or credits, and to quit to the main menu. I’m using C#, and I haven’t found any tutorials that really explain how to create a pause menu. I already looked that the unity communities pause menu but that didn’t really help.

a very simple example:

using System;
using UnityEngine;

public class pause : MonoBehaviour
{
	bool paused = false;

	void Update()
	{
		if(Input.GetButtonDown("pauseButton"))
			paused = togglePause();
	}
	
	void OnGUI()
	{
		if(paused)
		{
			GUILayout.Label("Game is paused!");
			if(GUILayout.Button("Click me to unpause"))
				paused = togglePause();
		}
	}
	
	bool togglePause()
	{
		if(Time.timeScale == 0f)
		{
			Time.timeScale = 1f;
			return(false);
		}
		else
		{
			Time.timeScale = 0f;
			return(true);	
		}
	}
}

I don't really know that much about C#, I'm more into JavaScript.

But, you could set it so that when your game is meant to be paused, just set the Time.timescale to 0 like this: `Time.timeScale == 0.0F`. (That is in C# by the way). Then just go `Time.timeScale == 1.0F` to set it back to normal.

Alternatively, if you're having a lot of trouble, I made a pause menu in JavaScript that you can download for free of the Asset Store.

It doesn't have a credits button, but it has a main menu button, but I'm sure that if you are OK with scripting, you could edit it!!!!!!!!!!!!!

Here is the link: http://u3d.as/content/grady-featherstone/pause-menu/1Zg

Also, you may like to check this out: http://unity3d.com/support/documentation/ScriptReference/Time-timeScale.html

It is the script reference for Time.timescale!

But here is a simple example in JavaScript on how you might stop the game when the escape button is pressed, and then unpause it:

private var pauseEnabled = false;
function Update(){

        //check if pause button (escape key) is pressed
        if(Input.GetKeyDown("escape")){

            //check if game is already paused       
            if(pauseEnabled == true){
                //unpause the game
                Time.timeScale = 1;         
            }

            //else if game isn't paused, then pause it
            else if(pauseEnabled == false){
                Time.timeScale = 0;
            }
        }
    }

Hope this helps you...

Comment back if you need more help...

That’s in French, but I’ve creat it alone !

using System.Linq;

using System.Collections.Generic;


public class MenuPause : MonoBehaviour 
{

	#region Attributs

	private bool isPaused = false; // Permet de savoir si le jeu est en pause ou non.

	#endregion
	
	#region Proprietes
	#endregion

	#region Methodes
	
	void Start () 
	{
	
	}
	
	
	void Update () 
	{
		// Si le joueur appuis sur Echap alors la valeur de isPaused devient le contraire.
		if(Input.GetKeyDown(KeyCode.Escape))
			isPaused = !isPaused;


		if(isPaused)
			Time.timeScale = 0f; // Le temps s'arrete
		
		else
			Time.timeScale = 1.0f; // Le temps reprend


	}

	void OnGUI ()
	{
		if(isPaused)
		{
		
			// Si le bouton est présser alors isPaused devient faux donc le jeu reprend.
			if(GUI.Button(new Rect(Screen.width / 2 - 60, Screen.height / 2 - 60, 100, 40), "Continuer"))
			{
				isPaused = false;
			}

			// Si le bouton est présser alors on ferme completement le jeu ou charge la scene "Menu Principal
			// Dans le cas du bouton quitter il faut augmenter sa postion Y pour qu'il soit plus bas
			if(GUI.Button(new Rect(Screen.width / 2 - 60, Screen.height / 2 + 00, 100, 40), "Recommencer"))
			{
				// Application.Quit(); 
				Application.LoadLevel("CarBigParcour");
			}

			if(GUI.Button(new Rect(Screen.width / 2 - 60, Screen.height / 2 + 60, 100, 40), "Quitter"))
			{
				Application.Quit(); 
				// Application.LoadLevel("CarBigParcour");

Hello, I borrowed some of this code to create a toggle-able inventory for my game, my question is how do I make my cursor unlock and stay visible so I can interact with the inventory. My cursor is hidden by default but oddly enough I can’t seem to find any script responsible for hiding it, unless that’s just a Unity feature now… I tried using

CursorLockMode.None;
Cursor.visible = true;

after the keypress to open the menu, the cursor just flashes and remains locked and hidden…
