Card Game "yielding" between Dealing cards

Unity Engine
1

Hi All,

Im stuck on how to yield between dealing cards for example once the dealer button is clicked deal out 4 cards with a 1 second delay between them.
I’ve been reading your not supposed to use yield WaitForSeconds in Update or FixedUpdate so that means I can’t use yield in OnGUI either because OnGUI is called twice per frame. So how would I solve this? I’ve tried to figure out as many different ways that I can think of but to no avail. I could use some expertise in figuring this out.

Here is my last attempt so far:

function OnGUI() 
{ 
	if (GUI.Button (Rect (0,0,100,35), "Deal")) 
	{
		Card1();
	}
}
function Card1()
{
	var newCard1 : GameObject = DealCard();
	Wait();
    	Card2();
}
function Card2()
{
	var newCard2 : GameObject = DealCard();
	Wait();
     	Card3();
}
//**** I did the same for Crad3 and Card4 ****//

function DealCard() : GameObject
{
    if(cards.Count==0)
    {
    	ResetDeck();
    }
	var card : int = Random.Range(0, cards.Count-1);
	var go : GameObject = GameObject.Instantiate(cards[card]) as GameObject;
	cards.RemoveAt(card);
    	return go;
}

Its generally a good idea to separate logic and UI.

Structurally you are unlikely to want different functions for different cards. Instead have a deal function that takes the number of cards to deal:

public List<Card> DealCards(int count) {
  List<Card> cards = new List<Card>(); // Its probably worth making a class to represent your cards instead of using gameobjects
  for (int i = 0; i < count; ++i) cards.Add(DealCard()); // Similar to existing but return the card not the GO
  return cards;
}

After this function executes trigger a view type class which shows your cards:

private IEnumerator DoShowDeal(List<Card> cards){
  foreach (Card card in cards){
    PlayCardAnimation(card);
    yield return new WaitForSeconds(animationDelay); // Or you could receive an event at the end of the animation which triggers the next animation
  }
}

public void ShowDeal(List<Card> cards){
  StartCoroutine(ShowDeal(cards));
}

And in your button (grr hate unity GUI):

  if (GUI.Button (Rect (0,0,100,35), "Deal"))
  {
      List<Card> cards = DealCards(5);
      tableView.ShowDeal(cards);
  }

Just a shadow of an idea, but maybe it will get you thinking along the right path.
