help with script

Hi guys.
tell me how to make a frozen screen when you press
(Example: I go to the trigger, I press the button "E", the text appears and the game freezes, and when it disappears, the game unfreezes)

Code (JavaScript):

1. var playerObject : GameObject;
2. var message : String = "";
3. var displayTime : float = 3;
4. var displayMessage : boolean = false;
5. var sound : AudioClip;
6. var audioS : AudioSource;
7. function Update() {
8.     displayTime -= Time.deltaTime;
9.     if (displayTime <= 0.0) {
10.         displayMessage = false;
11.     }
12. }
13. function OnTriggerStay(other : Collider) {
14.     if(other.collider.gameObject == playerObject && Input.GetKeyDown(KeyCode.E)&& !audio.isPlaying){
15.        audio.Play();
16.        displayMessage = true;  
17.        displayTime = 1.0;
18.        
19.     }
20. }
21. function OnGUI () {
22.     if (displayMessage) {
23.         GUI.Label(Rect(Screen.width/2 - 250, Screen.height- 100,700,50),"The lock is broken. I can't open the door.");
24.  
25.     }
26. }

tried to Time.timeScale = 1; but do not know how to unfreeze
thanks in advance!

 

No do Time.timeScale = 0; to pause.

 

I put 0, the game freezes, but not defrosted

 

defrost? like unpause? Just turn the timeScale back to 1

 

can help me with this?
I did not go out, or I'm doing something wrong
