public GameObject pauseScreen;
bool off = false;

	// Use this for initialization
	void Start () 
	{
		
	}
	
	// Update is called once per frame
	void Update () 
	{
		if (off == false) 
		{
			pauseScreen.SetActive(false);
			if (Input.GetKeyDown (KeyCode.P))
			{
				//wait here
				off = true;
			}
		}

		if (off == true) 
		{
			pauseScreen.SetActive(true);
			if (Input.GetKeyDown (KeyCode.P))
			{
				//wait here
				off = false;
			}
		}
	}

how would i do it so that it waits a second at the “//wait here” so it doesnt activate and then instantly deactivate the pause screen
P.S. im using unity 2017.3

Try this script

     bool off = false;

     // Use this for initialization
     void Start()
     {

     }

     // Update is called once per frame
     void Update()
     {
          if (off == false)
          {
               pauseScreen.SetActive(false);
               if (Input.GetKeyDown(KeyCode.P))
               {
                    //wait here
                    Invoke("setOffTrue", 1);
               }
          }

          if (off == true)
          {
               pauseScreen.SetActive(true);
               if (Input.GetKeyDown(KeyCode.P))
               {
                    //wait here
                    Invoke("setOffFalse",1);
                    
               }
          }


     }

     public void setOffTrue()
     {
          off = true;
     }
     public void setOffFalse()
     {
          off = false;
     }
