OnGUI skin problem

Unity Engine
1

Hi, I’m using GUI buttons to create a dialog type interaction with a person. I can get the buttons to display the text. the problem i’m having is that i want to change some of the properties in the GUI skin. Again I can do this but I need to be able to do it at a button click not when the scene loads.

private var Ypos1 : float = 0.0;
private var Ypos2 : float = 0.0;
private var Ypos3 : float = 0.0;
private var Ypos4 : float = 0.0;




private var showDropdownButtons1 : boolean;
private var showDropButtonsUP1 : boolean;


var dropSpeed : float = 400.0;

var messageText = "";

var guiSkin : GUISkin;

function Update(){
   
   if(showDropdownButtons1 == true){
   
      Ypos1 += Time.deltaTime * dropSpeed;
      Ypos2 += Time.deltaTime * dropSpeed;
      Ypos3 += Time.deltaTime * dropSpeed;
      Ypos4 += Time.deltaTime * dropSpeed;
      
      if(Ypos1 >= 30){
         Ypos1 = 30;
         }
            
         if(Ypos2 >= 130){
            Ypos2 = 130;
            }
      
            if(Ypos3 >= 230){
               Ypos3 = 230;
               }
         
               if(Ypos4 >= 330){
                  Ypos4 = 330;
                  }
                  
   
if(showDropButtonsUP1 == true){
         Ypos1 -= Time.deltaTime * dropSpeed;
         Ypos2 -= Time.deltaTime * dropSpeed;
         Ypos3 -= Time.deltaTime * dropSpeed;
         Ypos4 -= Time.deltaTime * dropSpeed;
         
         if(Ypos1 >= 0 || Ypos2 >= 0 || Ypos3 >= 0 || Ypos4 >= 0){
         Ypos1 = 0;
         Ypos2 = 0;
         Ypos3 = 0;
         Ypos4 = 0;
         showDropButtonsUP1 = false;
         showDropdownButtons1 = false;
         }   
}               
                  
}

}

// you can change anything in red
function OnGUI (){
		
		GUI.skin = guiSkin;
		
		//~ GUILayout.BeginArea (Rect (100, 50, Screen.width-200, Screen.height-100));

I am not very experienced with the OnGUI functionality with unity/ I just wanted to give your post a bump and suggest putting your code within the code brackets

So instead of

if (not in code brackets)
{
crash horribly;
}

you have

if (in code brackets)
{
     game makes millions!
}

It will help someone who can help you read and understand your code much better.

Hi all,

As I’ve had no responses to this, I’ve had an idea as to how to do this. Make a new dialogue/conversation scene and load it when the player selects to talk to the NPC in game, not ideal and I haven’t tried to do it yet but just a thought…Is this the best way to do it? or am I barking up the wrong tree before i spend loads of time developing it and there is an easier way??
