Pausing game/Slowing it down in background of pause screen

Hey guys, I am doing a little project and was just wondering if/how I can pause a game behind a pause screen.

This is my interaction menu so far;

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class InteractionMenu : MonoBehaviour {
6.  
7.     private bool pressed;
8.  
9.     private bool EscapeMenu;
10.     private bool Inventory;
11.     private bool Chat;
12.  
13.     public GameObject EscapeMenuObj;
14.     //public GameObject InventoryObj;
15.     //public GameObject ChatObj;
16.  
17.     void Start () {
18.         pressed = false;
19.         EscapeMenu = false;
20.         Inventory = false;
21.         Chat = false;
22.     }
23.  
24.     void Update () {
25.  
26.         //Escape Menu
27.         if (Input.GetKey (KeyCode.Escape)) {
28.             if (!pressed) {
29.                 pressed = true;
30.                 if (!EscapeMenu) {
31.                     CursorLock ("Off");
32.                     EscapeMenu = true;
33.                     EscapeMenuObj.SetActive (true);
34.                 } else {
35.                     CursorLock ("On");
36.                     EscapeMenu = false;
37.                     EscapeMenuObj.SetActive (false);
38.                 }
39.             }
40.         } else {
41.             pressed = false;
42.         }
43.  
44.         //Inventory
45.         if (Input.GetKey (KeyCode.E)) {
46.             if (!Inventory) {
47.                 CursorLock ("Off");
48.                 Inventory = true;
49.                 //InventoryObj.enabled = true;
50.             } else {
51.                 CursorLock ("On");
52.                 Inventory = false;
53.                 //InventoryObj.enabled = false;
54.             }
55.         }
56.  
57.         //Chat
58.         if (Input.GetKey (KeyCode.T)) {
59.             if (!Chat) {
60.                 CursorLock ("Off");
61.                 Chat = true;
62.                 //ChatObj.enabled = true;
63.             } else {
64.                 CursorLock ("On");
65.                 Chat = false;
66.                 //ChatObj.enabled = false;
67.             }
68.         }
69.     }
70.  
71.     void CursorLock(string Switch){
72.         if (Switch == "On") {
73.             Cursor.visible = false;
74.             Screen.lockCursor = true;
75.         } else {
76.             Cursor.visible = true;
77.             Screen.lockCursor = false;  
78.         }
79.     }
80.        
81. }
82.  
83.  

 

You have not shown your game's script at all, but assuming all your moving stuff moves with reference to Time.deltaTime, you can adjust the game's timescale from the default 1 to maybe 0.2 to slomo everything moving.

 

Not sure if theres an easier/better way but thats how I do it most of the time.

 

Yeah, worked just as i needed it to, thanks
