How do i make a button that will change view into like a new canvas

so basically i want to click a button then a new screen will pop up and i can make more buttons on that screen and i can make a back button i already know how to make the back button all i need to know is how to make a button that will change view into like a new canvas or whatever

 

Sounds to me like you want to get organized with canvasses! I personally like to use Panels for this on a single Canvas.

Then you can put a script (Monobehaviour) on the Canvas, which you can invoke from any Panel. Just use the inspector to make buttons fire a method in the Canvas above them via their onClick() method. And have these method show / hide the individual Panels. You can invoke more then one method per button if needed.

With only a few screens I don't mind making them class variables, but you could make it as complex as you want. This example just alternates between two Panels when the pause button is pressed.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PauseMenuScript : MonoBehaviour
6. {
7.     public static bool GameIsPaused = false;
8.     public GameObject panelA;
9.     public GameObject panelB;
10.  
11.     private void Start()
12.     {
13.         panelA.SetActive(true);
14.         panelB.SetActive(false);
15.         Cursor.visible = false;
16.     }
17.  
18.     void Update()
19.     {
20.         if (Input.GetButtonDown("Cancel"))
21.         {
22.             if (GameIsPaused==true)
23.             {
24.                 Resume();
25.             } else
26.             {
27.                 Pause();
28.             }
29.         }
30.     }
31.  
32.     public void Pause()
33.     {
34.         panelA.SetActive(true);
35.         panelA.SetActive(false);
36.         Time.timeScale = 0f;
37.         Cursor.visible = true;
38.         GameIsPaused = true;
39.     }
40.  
41.     public void Resume()
42.     {
43.         panelA.SetActive(false);
44.         panelB.SetActive(true);
45.         Time.timeScale = 1f;
46.         GameIsPaused = false;
47.         Cursor.visible = false;
48.     }
49.  
50.     public void Quit()
51.     {
52.         SaveDataSystem.Quit();
53.     }
54. }
