QUIText Fade In?

Question

I use this code for QUIText to fade out:

  #pragma strict
  
  var color : Color;
  
  function Start(){
      
      color = Color.white;
  }
  
  function Update(){
  
      Fade();
  }
   
  function Fade(){
  
      while (guiText.material.color.a > 0){
          guiText.material.color.a -= 0.1 * Time.deltaTime * 0.05;
      yield;
      }
  }

How do i make it fade in instead of out?

Thanks For Help!

You are on the right track richyrich but remember that color values are between 0 and 1 in scripting (not 0 - 255 as in a color picker).

captainkrisu the Fade() function in the script above is being called every frame by Update(), so having a while loop seems very odd. You would use a loop if this was a coroutine that was activated once with the yield having an associated time value to slow the Fade process down.

Something like this will work(this will fade in and out repeatedly) :

 #pragma strict
 
 public var MyGUIText : GUIText;
 private var fFade_In_Speed : float;
 
 function Start() {
 
     fFade_In_Speed = 0.2;
     
     InvokeRepeating("Fade", 0, fFade_In_Speed);
 }
 
 function Fade() {
 
     if (MyGUIText.material.color.a >= 0) {
         MyGUIText.material.color.a -= 0.05;
         
     } else {
         MyGUIText.material.color.a = 0.0;
         CancelInvoke("Fade");
         InvokeRepeating("Fade_In", 0, fFade_In_Speed);
     }
 }
 
 function Fade_In() {
 
     if (MyGUIText.material.color.a <= 1) {
         MyGUIText.material.color.a += 0.05;
         
     } else {
         MyGUIText.material.color.a = 1.0;
         CancelInvoke("Fade_In");
         InvokeRepeating("Fade", 0, fFade_In_Speed);
     }
 }

Place this on the GUIText object. Then drag the GUIText object from the hierarchy window into the MyGUIText var box.
