How would I repeat an action for a specific case?

Hi,

I asked a question about my code before, but now I've come across another problem where the brushstroke designs (images) I specified for each letter of the alphabet, they only show once. For example when it sees a "p" in "apple" it only does the first "p" rather than both "p"'s I'm not sure how I would go about it. How would I make it repeat specific letters when needed to? Here's my code:
1. void tweet2design() {
      //background(233,240,242);
        //text(strTweets[j], textX+175,515, 650,100);
  
  /*if(strTweets.length >= textX) {
        textY = textY + 50;
  }*/ //loop();
        char[][] target;
        target = new char[strTweets.length][];
            for(int i = 0; i < strTweets.length; i++) {
  
        target[i] = strTweets[i].toCharArray();
        char c = strTweets[i].charAt(i);
  
  
      if(j < strTweets.length) {
  
      newMills = millis();
  
        if(newMills > oldMills + 9000) {
            fill(53,alphaValue);
            background(255);
            textAlign(CENTER);
            text(strTweets[j], textX + 175,518, 650,100);
            alphaValue -=a;
        if(alphaValue < 0 || alphaValue > 255) {
          a *= -1;
        }
            //println("first display_time " + counter);
        oldMills = newMills;
        j++;
  
        if(millis() - lastTime >= DISPLAY_TIME) {
  
        counter = ++counter % images.length;
  
        lastTime = millis();
  
      }
            if(alphaImage > 0) { alphaImage -= 1;
  }
       if(millis() - lastTimeImg >= DISPLAY_TIME) {
  tint(255, tintTime()%150);
  lastTimeImg = millis();
       }
  alphaImage -= b;

Twitter API: Sketch only shows last tweet

Hi!

I don't understand code too well so please bare with me! I have no problem displaying the tweets on my sketch, but I don't know how to go about displaying them all in a timely manner one at a time (one by one). For example, after it displays a tweet for a specific duration it goes to the next one. My sketch keeps going to the last tweet (it seems that Processing can only read in 14 tweets before it re-cycles again) instead of displaying the first to last tweet.

Here's my code:
1. PFont font;
  PImage aB,bB,cB,mB,nB,oB,yB,zB,
           dG,eG,fG,pG,qG,rG,

How to read a String, char by char at a time

Hi,

I'm sort of stuck on this. So I want to be able to read an ongoing live (twitter feeds) String, char by char and once it reads a char have it specifically do an action.

I have the parsing of the twitter String, but I'm stuck on reading each character individually and doing an action afterward. If someone could suggest anything, I'd really appreciate it! Thanks.

Here's my code:
1. PFont font;
  
  String[] alphabet;
  String[] strTweets;
  String delimiters = " ,.?1;:";
  
  float textX = width;
  int counter = 0;
  
  int index = 0;
  int x = 0;
  int nextPage = 0;
  
  void setup() {
  
  size(1024,288);
  background(255,253,245);
  font = createFont("Arial-Bold.vlw", 70);
  textFont(font);
  textAlign(LEFT);
  ellipseMode(CENTER);
  //Styles
  imageMode(CENTER);
  smooth();
  //Tweets
  fill(254,49,30);
  textFont(font, 20);
  //Search
  XMLElement rss = new XMLElement(this,
  "http://search.twitter.com/search.atom?q=search&show_user=true");
  
  XMLElement tweets[] = rss.getChildren("entry/title");
  
  strTweets= new String[tweets.length];
  for(int i = 0; i < tweets.length; i++) {
      strTweets[i] = tweets[i].getContent();
  
  }
  }
  
  void draw() {
  switch (nextPage) {
      case 0://Splash Page
      background(255,253,245);
      tweet2char();
      fill(202,236,245);
      pushMatrix();
      noStroke();
      fill(202,236,245);
      ellipse(beat(),20,150,150);
      fill(253,215,181);
      ellipse(1024,beat()+220,150,150);
      stroke(0);
      popMatrix();
      break;
  
      case 1://Interface/Tweets
      background(255,253,245);
      tweets();
      pushMatrix();
      noStroke();
      fill(202,236,245);
      ellipse(beat()+50,100,100,100);
      fill(253,215,181);

      fill(202,236,245);
      ellipse(1024,beat()+225,50,50);
      popMatrix();
      break;
  
  }
  }
  
  void tweets () {//Scroll Tweets
  fill(254,49,30);
  if(index < strTweets.length) {
      text(strTweets[index], textX, 220);
      textX = textX - 1.5;
      float w = textWidth(strTweets[index]);
      if(textX < -w) {
        textX = width;
        index = (index + 1) & strTweets.length;
  
      }
  }
  }

  //for(char c : target)
  //println(c);
  println("this is: " + i + "target: " + target);
  
  //println("this is char: " + c1);
  //println("this is: " + strTweets.charAt(i));

  }
  
  /*void test2char() {
