Simple choose your own adventure?

I've been looking for a choose your own adventure example in processing, but i can't find one. Do any of you know where to find code of one?

class Pair {
  String txt;
  int id;
  Pair(int iid, String itxt){
    id = iid;
    txt = itxt;
  }
}

class State {
  Pair here;
  ArrayList<Pair> links;
  State(int iid, String itxt){
    here = new Pair(iid, itxt);
    links = new ArrayList();
  }
  void add_link(int to_id, String option_txt){
    links.add( new Pair(to_id, option_txt) );
  }
  void draw(){
    text(here.txt,20,20,width-40,height/2-20);
    // This could be more dynamic.
    for(int i=0; i< links.size(); i++){
      text(links.get(i).txt, 20,height/2+20+(i*height/4),width-40,height/4);
    }
  }
  void mouse(){
    // This could be more dynamic too.
    if(mouseY>3*height/4){ if(links.size() > 1){ state = links.get(1).id;} return;}
    if(mouseY>height/2){ state = links.get(0).id; return;}
  }
}

State[] states = new State[3];
int state = 0;

void setup(){
  size(220,220);

  states[0] = new State(  0, "You are in a room. There is a box here.");
  states[0].add_link(  1, "Get in the box. ->");
  states[0].add_link(  2, "Leave the room. ->");

  states[1] = new State(  1, "You are in a box.");
  states[1].add_link(  0, "Leave the box. ->");

  states[2] = new State(  2, "You are in outside a room.");
  states[2].add_link(  0, "Enter the room. ->");

}

void draw(){
  background(0);
  fill(255);
  states[state].draw();
}

void mousePressed(){
  states[state].mouse();
}

This is very basic, ugly code, and could do with a lot of work.
