Help with pausing script.

Questions & Answers
1

When I press ‘P’ the game will pause, and there is supposed to be GUI coming up. The game pauses but the only thing is that the GUI won’t show up and there are no errors. Here’s my script.

using UnityEngine;
using System.Collections;

public class Pause : MonoBehaviour {

	public float x;
	public float y;
	public float sizex;
	public float sizey;

	// Use this for initialization
	void Start () {
	 Time.timeScale = 1;



	
	}
	
	// Update is called once per frame
	void Update () {


	
	
	}

	void OnGUI()
	{
	    if(Input.GetKeyUp(KeyCode.P))
		{
		  Time.timeScale = 0;
			
		 GUI.Box(new Rect(x, y, sizex, sizey), "Paused");
		}

	}
}

Don’t use GetKey inside your GUI code. Only place GUI methods in GUI. You need to place your GetKey function inside of Update so it will be checked every frame. If you’re wanting to toggle the pause w/ the P key, use a bool that is toggled by GetKey.

using UnityEngine;
using System.Collections;

public class Pause : MonoBehaviour 
{
	public float x;
	public float y;
	public float sizex;
	public float sizey;

	bool pause = false;

	void Update () 
	{
		if(pause)
			Time.timeScale = 0;
		else
			Time.timeScale = 1;
		if(Input.GetKeyDown (KeyCode.P))
			pause = !pause;
	}

	void OnGUI()
	{
		if(pause)
			GUI.Box(new Rect(x, y, sizex, sizey), "Paused");
	}
}

The GUI.Box(new Rect(x, y, sizex, sizey), “Paused”); need to be outside of the if statement.

Here:

bool paused;
    
    void Update () {
     if(Input.GetKeyUp(KeyCode.P))
    {
    Time.timeScale = 0;
    paused = true;
    }   
     
    void OnGUI()
    {
    if(paused)
    {
     GUI.Box(new Rect(x, y, sizex, sizey), "Paused");
    }
    }
