Wait For User to click GUI.Button

Hi, i am writting simple card game just to learn programming and i have been wondering how to wait in application for user to click button.

The idea is that i start the game and draw cards - but after that i want to give user choice to redraw cards- so i show gui buttons. But the problem is that the code continues to execute or when i make infinite loop unity freezes.

Code (CSharp):

1. //PlayerTurn function
2. void  PlayerTurn(){
3.   isPlayerTurn = false;
4.   //Check if is first turn
5.   if (isFirstTurn == true) {
6.    //Draw cards
7.    FirstDraw();
8.  
9.    ShowRedrawButtons = true;
10.  
11.    //Wait here for user input
12.    //while (ShowRedrawButtons == true){
13.    //}
14.  
15.    isFirstTurn = false;
16.   }
17.  
18.   //PlayerHand.Add(DrawCard());
19.  
20.   for(int i = 0;i <= PlayerHand.Count - 1;i++){
21.    Debug.Log((string)PlayerHand[i]);
22.   }
23. }

and this is my OnGUI Function

Code (CSharp):

1. void OnGUI(){
2.         if (ShowRedrawButtons == true) {
3.             if (GUI.Button (new Rect (Screen.width / 2 - 110, Screen.height / 2, 100, 50), "Redraw")) {
4.                 Redraw ();
5.                 ShowRedrawButtons = false;
6.             }
7.             if (GUI.Button (new Rect (Screen.width / 2 + 110, Screen.height / 2, 100, 50), "Don't Redraw")) {
8.                 ShowRedrawButtons = false;
9.             }
10.         }
11.     }

In line 12-13 if i uncommet the application freezes. I have no idea how to achieve this in other way. I call PlayerTurn in update function

 

That's because OnGUI() never gets called because you are just looping forever in lines 12-13.

Replace it with:

Code (CSharp):

1. if (ShowRedrawButtons == true)
2.    return;

This will just bypass everything in the update() until they click the button

 

It's not exactly the thing i need but i can tweak it to my needs ... i hope

The problem now is that i need to start from the point we stopped but i think i''ll work it out.

 

yield wait for seconds use it
