Hello everyone,
Hopefulle someone can find the problem with my applet lol.
We're suppose to see a new line of text (external file) appear each time the user click on the screen.
I wanted to use a "fade-in" so the text would appear gradually. I tried using the alpha channel but it doesn't seem to work for some reason:
The text appear in one shot, without the alpha.

Code:

//===================================================
//Global variables
//===================================================
PFont f;							   // variable for font
String[] textfile;					     // will contain contents of external file
int text_index = 0;					    // tracks location in the textfile array
int xPosition = 20;					    // position of the line of text on the screen
int yPosition = 50;					   //position of the line of text on the screen
//---------------------------------------------------
//setup
//---------------------------------------------------
void setup(){						
  size(600, 600) ;
  background(0)  ; 
  frameRate(10)  ;
  fill(0);
  smooth();
  f = loadFont("BlackadderITC-Regular-30.vlw");	 //load font  
  textFont(f, 30);						// set the display font												  
  textfile = loadStrings("kaelar.txt");		   // load the contents of the external file into the string array
}



//===================================================
//FUNCTIONS
//===================================================
void sprayText(){						// writes a line of text at x and y position
  
  if (text_index < textfile.length) {		    // are we past the end of the string array?
    
    
    for(int i=0; i<255; i++){
	 fill(255,i);					    // The alpha of this fill doesn't seem to be working?
	 text(textfile[text_index], xPosition, yPosition); 
	 //background(100,10); **edit**oops this isn't suppose to be here :P
    }
    text_index++;
    xPosition = xPosition+40;
    yPosition = yPosition+40;  
  }
  else{
    text_index = 0;
  }					// yes...reset index of string array to beginning
  
}
//===================================================
void mousePressed(){
  sprayText();
}

//===================================================
//DISPLAY
//===================================================
void draw(){
}
  

thank you in advance

That would explain it. Then I shall try something else

thank you for your help
