I've been searching around trying to figure out how to do this but alas I can't figure it out :( I am trying to send data from Arduino to processing and have processing spit out a text file that I will then have Arduino read. I have 8 RGB LEDS with 3 shift registers, a DHT Temp Sensor, a photoresistor, and an electret microphone. The input from the 3 senors are controlling the color of the RGB LEDS. My code on the Arduino side works but I can't get processing to read the data and save it to a text file. Here is my code so far (it's probably all wrong, I'm new to programming)

1. import processing.serial.*;
   Serial myPort;
   PrintWriter output;
   int r;
   int g;
   int b;
   
   void setup() {
     output = createWriter("data/data.txt");
     myPort = new Serial(this, "/dev/tty.usbmodemfa121", 9600);
     myPort.bufferUntil('\n');
   }
   
   void serialEvent(Serial myPort){
     String myString = myPort.readStringUntil('\n');
     int data [] = int(split(myString, ','));
     if (data.length > 1) {
       r = data[0];
       g = data[1];
       b = data[2];
       println("Printing RGB Vals to File");
       output.println(r+","+g+","+b);
       output.flush();
     }
   }
   
   void stop(){
     output.close();
     super.stop();
   }
   

Thanks to the help from GoToLoop, I have my game *ALMOST* working ^^. But I am having trouble setting up a scoring system for the game. I also need to make the game "end" after 20 seconds. Can anyone help me? Its very urgent! Here's the link to the code because the game has many images

its the Shooting_game_v2 zip file

please please help!!

Hi,  I am a new programming student and for my school final, I am working on a mini game, where you have to shoot werewolves in a set amount of time. How can I make it so that the werewolf image is a button that you can click on it and after you click on it twice, it disappears? Really need the help, I have the girl shooting and the werewolf walking. Download in comment below >_<

1. //DECLARING OBJECTS
   Werewolf werewolf;
   
   //BACKGROUND
   
   float r = 0.8;
   PImage bg;
   
   //SHOOT LEFT
   
   PImage shootleft;
   
   //SHOOT RIGHT
   
   PImage shootright;
   
   //STAND
   
   float v = 0.5;
   PImage standleft;
   PImage standright;
   
   //SETUP
   
   void setup() {
   
     size (650, 700);
     bg = loadImage ("bg_0.png"); //load background
     standleft = loadImage ("stand_left.png"); //load standing left image
     standright = loadImage ("stand_right.png"); //load standing right image
     shootleft= loadImage ("shoot_left.png"); //load shooting left image
     shootright= loadImage ("shoot_right.png"); //load shooting right image
     werewolf = new Werewolf(); //load werewolf class
   }
   
   //DRAW
   
   void draw() {
     frameRate(10);
     scale(v); //scale bg image
     image(bg, 0, 0); //display bg image
     scale (r); //scale Ellen image
   
     if (mousePressed  && mouseX> width/2) { //
       image(shootright, 500, 850);
     }
     else if (mousePressed) {
       image(shootleft, 500, 850);
     }
     else if (mouseX > width/2) {
       image(standright, 500, 850);
     }
     else {
       image(standleft, 500, 850);
     }
   
     werewolf.display(); //call display method
     werewolf.movement();
   }
