How can i make pause menu

Hello Hajamat. A pause menu is rather simple. Some code off the top of my head would be this:

 bool pause=false;
 
 Void Start(){
      
 }
 Void Update(){
     if(pause){
          //Disable Movement Scripts Example:
          GetComponent<PlayerMovement>().enable=false;
      }else {
          //Enable Movement Scripts
          GetComponent<PlayerMovement>().enable=True;
      }
 }
 void OnGUI(){
      GUI.skin.label.fontSize=Screen.height/50;
      if(GUI.Button(new Rect(Screen.width/20,Screen.height-Screen.height/10,Screen.width/20,Screen.height/20),"Pause")){
           pause=true;
 }
 if(pause){
      //Draw pause menu stuff.
 }
 }

Thats just off the top of my head so there might be errors, But it should work.

the simpliest way to pause the game is Time.timescale = 0; this will Pause the game but if you press any keys while doing this once you set the Time.timescale = 1; the code from the keys will execute so the way i usally do this is in my GameManager Script thats easyli accesible from all scripts i make a bool called Pause and check on all Scripts that has Key press commands

Example

  if (FindObjectOfType<GameManager>().Pause != true && getKey(keycode.Space))
 {
 // execute code
 }
 else 
 {
 // do nothing the game is pasued
 }
