need help with delay in void Update c#

Questions & Answers
1

Could anyone help me? I need some delay before “GameObject.Find(“FadeGameObject”).GetComponent(). BeginFade(1);”
but I can’t use coroutine. And is it OK what I use before Application.LoadLevel? It works but I am not sure that it a good way ( I am not a programmer)

void Update ()
	{
		

		if (youWin) 
		{

		GameObject.Find("FadeGameObject").GetComponent<Fading>(). BeginFade(1);

		// .. increment a timer to count up to restarting.
			restartTimer += Time.deltaTime;
			
			// .. if it reaches the restart delay...
		if (restartTimer >= timeDelay) 
			{
		
			Application.LoadLevel(nextLevel);

			}

       	}
	}

You can use code before Application.LoadLevel(), there’s nothing wrong with that. Also coroutines work fine, not sure why you say you can’t use them. Anyway, if you want a delay before fading, then you can use the timer that is already present in the function.

	void Update ()
	{
		if (youWin) 
		{
			// .. increment a timer to count up to restarting.
			restartTimer += Time.deltaTime;
			
			// .. if it reaches the restart delay...
			if (restartTimer >= timeDelay) 
			{
              // might want add a check here, so BeginFade gets called only once. example: 
              if (GameObject.Find("FadeGameObject").GetComponent<Fading>().IsFading == false){
		        GameObject.Find("FadeGameObject").GetComponent<Fading>().BeginFade(1);
              }
			}

			if (restartTimer >= timeDelay + 1f)	// Replace 1f for the duration of the fade
			{
				Application.LoadLevel(nextLevel);
			}
		}
	}

I have just found the way to use coroutine but anyway thank you for the answer. Frankly speaking I did not understand your check code, what is “isFading” and why should it be “false”? It does not work for me or I do something wrong.
And I heard that using GetComponent within void update is not a good idea and one should store it in a variable in Start or Awake. What do you thing about it?
