Who knows how to make this read every letter, not just the first one. (Reading Txt. files)

FetaCheese

Hey guys, Im trying to make processing read out the letters in this txt. file. There are 4 letters in the file all scrambled up looking like this (gtcclclgtlcgttttgl). As of right now it is reading all of the letters as i can see in the bottom of the programming window, yet it is only making sounds for the first time that specific letter appears. I'm guessing it is a problem in my if statement but can anyone make it continue after it has read that specific letter? Thankyou thankyou

  bass4 = minim.loadFile("beep-4.mp3");
  bass5 = minim.loadFile("beep-5.mp3");
}
void draw() { 

  if (letter == 'A') {
    bass2.play();
    stroke(255);
    smooth();
    noFill();
    ellipse(100, 100, 100, 100);
    i++;
  }

  if (letter == 'C') {
    bass3.play() ;
    stroke(255);
     smooth();
    noFill();
    ellipse(400, 100, 100, 100);
    i++;    
  }
  if (letter == 'G') {
    bass4.play() ;
    stroke(255);
     smooth();
    noFill();
    ellipse(400, 400, 100, 100);
    i++;

  if (letter == 'T') {
    bass5.play();
    stroke(255);
     smooth();
    noFill();
    ellipse(100, 400, 100, 100);
    i++;   
  }

  letter = data.charAt(i); 
  println(letter);
  i++;
}

maybe you need a** for loop** that works as long as there are letters in the file?? Then it will keep going through the code? And I think you need only one i++ at the end.

I'm new at this, so just trying to learn to help.

can i get a rewind()?

you need to call rewind() to get samples to play again. play() just continues from where it was, and given that it was at the end so you won't hear anything.

Earlier, I have written a similar code here .
