How to change color automatically in processing.exe?

I currently learned about processing.exe. I've made a snake game in processing and I want to modify it. What I want is every time the snake eats food, the food that is moving randomly also gets given random colors.
here's my code:
snake s;
int grid = 15;
PVector food;
int r;
int g;
int b;
int warna;
void setup() {
size(600, 600);
s = new snake();
food = new PVector();
r = (int)random(255);
g = (int)random(255);
b = (int)random(255);
frameRate(15);
newFood();
}
void draw() {
background(0);
s.showScore();
s.display();
if (s.gameOver()) {
background(0);
textAlign(LEFT);
textSize(25);
fill(255);
text("Game Over", 10, 10, width - 20, 50);
noLoop();
}
if (s.eat(food)) {
newFood();
}
s.move();
fill (r, g, b);
rect (food.x, food.y, grid, grid);
}
void newFood() {
food.x = floor(random(width));
food.y = floor(random(height));
food.x = floor(food.x/grid) * grid;
food.y = floor(food.y/grid) * grid;
if (food.x == floor(random(width)) && food.y == floor(random(height))){
fill (r = (int)random(255), g = (int)random(255), b = (int)random(255));
rect( food.x, food.y, grid, grid);
}
}
void keyPressed() {
if (keyCode == UP) {
s.arah(0, -1);
} else if (keyCode == DOWN) {
s.arah(0, 1);
} else if (keyCode == RIGHT) {
s.arah(1, 0);
} else if (keyCode == LEFT) {
s.arah(-1, 0);
}
}
And this are the snake :
class snake {
float x = 0;
float y = 0;
float xspd = 1;
float yspd = 0;
int panjang = 0;
ArrayList<PVector> body = new ArrayList<PVector>();
snake() {
}
boolean eat(PVector pos) {
float d = dist(x, y, pos.x, pos.y);
if (d < 1) {
panjang++;
return true;
} else {
return false;
}
}
void arah(float x, float y) {
xspd = x;
yspd = y;
}
boolean gameOver() {
for (int i = 0; i < body.size(); i++) {
PVector pos = body.get(i);
float d = dist(x, y, pos.x, pos.y);
if (d < 1) {
panjang = 0;
body.clear();
return true;
}
}
return false;
}
void move() {
if (panjang > 0) {
if (panjang == body.size() && !body.isEmpty()) {
body.remove(0);
}
body.add(new PVector(x, y));
}
x = x + xspd*grid;
y = y + yspd*grid;
x = (x + width) % width;
y = (y + height) % height;
}
void display() {
noStroke();
fill(255);
for (PVector bagi : body) {
rect(bagi.x, bagi.y, grid, grid);
}
rect(x, y, grid, grid);
}
void showScore() {
textAlign(LEFT);
textSize(25);
fill(255);
text("Score: " + body.size(), 10, 10, width - 20, 50);
}
}
I've tried to change the color with declare r, g, b and assign a random color to it. But the food color doesn't seem to change every time the snake eats the food. Any suggestions on what I should do?

You're doing good so far. The only part you missed is that you want to change the food's color when you create some new food. So... you just have to take this part of the setup() method:
r = (int)random(255);
g = (int)random(255);
b = (int)random(255);
and move it in the newFood() method.
Hope this helps. Have fun!

Collisions in processing

My game is a shooting game for school. I need help on the collision between my bullet and my enemy. I have placed the bullet class with my player but for some reason it keeps on passing through it and not disappearing. The first example below shows the weapon class which is for the bullet and the one underneath that is the main.
class Weapons{
PImage bullet;
int speed;
int imageSize = 20;
float x = 20;
float y = 20;
float m;
int damage = 5;
int[] src = new int[2];
float[] dest = new float[2];
Weapons(int x, int y){
speed = 12;
dest[0] = mouseX;
dest[1] = mouseY;
src[0] = x;
src[1] = y;
m = (dest[1]-src[1]) / (dest[0]-src[0]);
this.x = x;
this.y = y;
bullet = loadImage("bullet.png");
bullet.resize(imageSize,imageSize);
}
boolean shooting(){
image(bullet, x, y); // if attack is true then renfer the image
x += speed;
y = (m * (x - dest[0])) + dest[1];
return (x > width || y > height);
}
boolean crash(Enemy enemies) {
//// return the result of checking if the plane has crashed into the bird
return abs(this.x-enemies.x) < bullet.width && abs(this.y - enemies.y) < bullet.height;
}
}
Maincharacter MC;
Goal G;
ArrayList<Enemy> enemies = new ArrayList<>();
ArrayList<Weapons> bullets = new ArrayList<>();
final int Playing = 0;
final int Finish = 1;
int gameMode = Playing;
//Enemy[] enemies = new Enemy[10];
PImage background; // creating background
int bgX = 0;
void setup(){
size(800,500);
MC = new Maincharacter(100,3);
//E1 = new Enemy();
G = new Goal(100,20);
background = loadImage("Battleground1.png");
background.resize(width*2,height); //set image to be same size as the canvas
for(int i = 0; i<2; i++){ // i represent how many enemy I want.
enemies.add(new Enemy((int)random(200,850), (int)random(0, height- 150) ) );
}
//for(int i=0 ; i < enemies.length ; i++){
//enemies[i] = new Enemy(); }
}
void draw(){
if(gameMode == Playing){
background();
MC.display();
G.display();
for(Enemy E : enemies){
E.update();
if (MC.crash(E)){
gameMode = Finish;
}
}
for(Weapons W: bullets){
W.update();
if(enemies.crash(W)){ // doesnt exist
gameMode = Finish;
}
}
// for(int i=0 ; i < enemies.length ; i++){
//enemies[i].update(); }
}}
void keyPressed(){
// creating the movemnt for my main charcter
MC.move();
if (keyCode == RIGHT || keyCode == 68 ){
MC.x += 10;
} else if (keyCode == UP || keyCode == 87) {
MC.y -=10;
} else if (keyCode == LEFT || keyCode == 65){
MC.x -= 10;
} else if(keyCode == DOWN || keyCode == 83 ){
MC.y += 10;
} else if (keyCode == 32) { // space bar
MC.attack_function(); // call attack function to create bullet object
}// make an attack
}
void mousePressed(){ // when mouse is pressed call attack function to create bullet object
MC.attack_function();
}
void background(){
//scrolling background image
image(background, bgX, height/2); //draw image to fill the canvas
//draw image again off the right of the canvas
image(background, bgX+background.width, height/2);
bgX -= 4;
if(bgX == -background.width ) //if first image completely off the canvas
{
bgX=0; //reset back to initial value background
}
}
What I want is to have bullet colliding with the enemies and then disappearing.

You are trying to call the method enemies.crash(W) but enemies is some collection of Enemy instances. Enemy does not provide the method crash as well.
You have to loop for each of your enemies all of your weapons and call the method crash on the Weapon instance giving the current enemy, something like:
for (Enemy enemy: enemies){
enemy.update();
if (mainCharacter.crash(enemy)) {
gameMode = Finish;
}
for (Weapons weapon: bullets) {
weapon.update();
if (weapon.crash(enemy)) {
gameMode = Finish;
// TODO: are you sure that killing an enemy finishes the game?
}
}
}
(Please note that I used mainCharacter instead of MC here for better readability.)

Processing - Add hitTest and mousePressed to an Animation with 100 balls

I want to create an ArrayList of ball objects, which should be in a loop until there are 100 pieces.
Now my problem: I must implement a function hitTest, so that when you click on a ball it gets removed. In the same position, there should appear two balls then, which go into a different direction.
Can someone help me? I am so lost...
Here's my code so far:
Ball b;
ArrayList<Ball> balls;
void setup() {
size(800, 800);
balls = new ArrayList<Ball>();
for (int i = 0; i<100; i++) {
drawBall();
}
}
void draw() {
background(255);
//b.update();
for (int i= 0; i<balls.size(); i++) {
balls.get(i).update();
}
}
void drawBall() {
Ball b = new Ball();
balls.add(b);
}
class Ball {
private float x;
private float y;
private float ballSize;
private float dirX;
private float dirY;
private boolean moving = true;
Ball() {
this.x = width/2;
this.y = height/2;
this.ballSize = random(10.0, 30.0);
this.dirX = random(-3.0, 3.0);
this.dirY = random(-3.0, 3.0);
if (this.dirX<1.0 && this.dirX>1.0) //1 statt -1 macht zufälliger { this.dirX = 1.0; }
if (this.dirY<1.0 && this.dirY>1.0) {
this.dirY = 1.0;
}
}
public void update() {
stroke(255);
fill(random(255), random(255), random(255), random(255));
ellipse( this.x, this.y, this.ballSize, this.ballSize);
if (this.moving == true) {
this.x += this.dirX;
this.y += this.dirY;
}
if (this.x+ this.ballSize/2> width ||this.x- this.ballSize/2<0) {
this.dirX= dirX*-1;
}
if (this.y+ this.ballSize/2> height ||this.y- this.ballSize/2<0) {
this.dirY= dirY*-1;
}
}
}

Break your problem down into smaller, simpler steps.
e.g.
when you click on a ball, it gets removed. In the same position, there should appear two balls then, which go into a different direction.
when you click on a ball: you can mix the dist() function (to check if the distance between the mouse and a ball is smaller then the radius) with mouseClicked() (or mousePressed() / mouseReleased())
it gets removed: you already called balls.add(). Similarly you can call balls.remove() passing the ball object or index to remove (depending on the case)
same position: you need to remember (store the coordinates) of the ball that was clicked to add two balls at the same position
different direction: you already do that in the Ball() constructor: you can apply the same logic on each new ball.
Here's a basic sketch to illustrate point 1, using dist():
void draw(){
background(255);
int ballX = 50;
int ballY = 50;
int ballRadius = 35;
if(dist(ballX, ballY, mouseX, mouseY) < ballRadius){
fill(0,192,0);
}else{
fill(192,0,0);
}
ellipse(ballX,ballY, ballRadius * 2, ballRadius * 2);
}
Paste this in a new sketch, run it and you should get the hang of using dist() in the context of your problem.
Regarding points 2,3,4 here's a modified version of your sketch with comments and a slightly different approach: instead of removing a ball to add a new one at the exact location with a different direction, simply randomise the direction. Visually it will look similar to a new ball (except the random size/colour). With the clicked ball being re-used, only a second one is added:
Ball b;
ArrayList<Ball> balls;
void setup() {
size(800, 800);
balls = new ArrayList<Ball>();
for (int i = 0; i<100; i++) {
drawBall();
}
}
void draw() {
background(255);
//b.update();
for (int i= 0; i<balls.size(); i++) {
// pass the mouse coordinates to each ball to check if it's hovered or not
balls.get(i).update(mouseX, mouseY);
}
}
// on mouse pressed
void mousePressed(){
for (int i= 0; i<balls.size(); i++) {
// make current ball reusable in this loop
Ball ball = balls.get(i);
// if ball is hovered
if(ball.isHovered){
// randomize direction of current ball
ball.setRandomDirection();
// add a new ball from the current location
balls.add(ball.copy());
}
}
}
void drawBall() {
Ball b = new Ball();
balls.add(b);
}
class Ball {
private float x;
private float y;
private float ballSize;
private float dirX;
private float dirY;
private boolean moving = true;
private color fillColor;
// property to keep track if the ball is hovered or not
private boolean isHovered;
Ball() {
this.x = width/2;
this.y = height/2;
this.ballSize = random(10.0, 30.0);
this.setRandomDirection();
this.fillColor = color(random(255), random(255), random(255), random(255));
}
// extract random direction calls into a re-usable function (handy for click / collision)
void setRandomDirection(){
this.dirX = random(-3.0, 3.0);
this.dirY = random(-3.0, 3.0);
if (this.dirX<1.0 && this.dirX>1.0) { //1 statt -1 macht zufälliger { this.dirX = 1.0; }
if (this.dirY<1.0 && this.dirY>1.0) {
this.dirY = 1.0;
}
}
}
public void update(int x, int y) {
// euclidean distance between this ball's coordinates a given x y position (e.g. mouse)
isHovered = dist(this.x, this.y, x, y) < this.ballSize / 2;
// optional: use stroke color to visually display highlighted ball
if(isHovered){
stroke(0);
}else{
stroke(255);
}
fill(fillColor);
ellipse( this.x, this.y, this.ballSize, this.ballSize);
if (this.moving == true) {
this.x += this.dirX;
this.y += this.dirY;
}
if (this.x + this.ballSize / 2 > width ||
this.x - this.ballSize / 2 < 0) {
this.dirX= dirX*-1;
}
if (this.y + this.ballSize / 2 > height ||
this.y - this.ballSize / 2 < 0) {
this.dirY= dirY*-1;
}
}
// utility function: simply copies this ball's x,y position to the new one
Ball copy(){
Ball clone = new Ball();
clone.x = this.x;
clone.y = this.y;
return clone;
}
}
The copy() method is flexible enough that it's ease to remove one ball to add two more if that is an absolute must. For example:
// on mouse pressed
void mousePressed(){
for (int i= 0; i<balls.size(); i++) {
// make current ball reusable in this loop
Ball ball = balls.get(i);
// if ball is hovered
if(ball.isHovered){
// add two new balls from the current location
balls.add(ball.copy());
balls.add(ball.copy());
// remove ball
balls.remove(i);
}
}
}

Drawing New Circles at click location while saving previous ones

Hi I want to draw new circles when I enter new radius for them and click button. I am supposed to position it with mouse. However after I draw circle I either can't draw new one or i can't position it mouse too.
import interfascia.*;
int numCircles = 500;
Circle[] circles = new Circle[numCircles]; // define the array
int k=0;
GUIController c;
IFButton b1;
IFTextField tn;
float bx;
float by;
boolean overBox = false;
boolean locked = false;
float xOffset = 0.0;
float yOffset = 0.0;
float r;
void setup() {
size(1439,800);
smooth();
noStroke();
bx=width/2;
by=height/2;
c = new GUIController (this);
b1 = new IFButton ("Click to draw", 600, 220, 100);
tn=new IFTextField("", 100,20,50);
c.add(b1);
c.add(tn);
}
void draw() {
background(205);
if (mouseX > bx-r && mouseX < bx+r &&
mouseY > by-r && mouseY < by+r) {
overBox = true;
if(!locked) {
}
} else {
overBox = false;
}
circles[k] = new Circle(bx,by,r);
circles[k].display(); // display all the circles
}
void actionPerformed (GUIEvent e) {
if (e.getSource() == b1) {
r=float(tn.getValue());
}
}
class Circle {
float x,y,r; // location
color c; // color
Circle(float x, float y, float r) {
this.x = x;
this.y = y;
this.r = r;
c = color(random(255));
}
void display() {
ellipse(x,y,10,10); // a circle at position xy
}
}
void mousePressed() {
if(overBox) {
locked = true;
} else {
locked = false;
}
xOffset = mouseX-bx;
yOffset = mouseY-by;
}
void mouseDragged() {
if(locked) {
bx = mouseX-xOffset;
by = mouseY-yOffset;
}
}
void mouseReleased() {
locked = false;
overBox=false;
}

You have two main options:
Option 1: Stop calling the background() function from your draw() function. This is what's clearing out old frames. If you remove that (or move it to setup(), then your old frames will never be cleared out.
Option 2: Store your state in a set of data structures. You can think of using arrays to store the position and radius of each of your circles. (Or better yet, create a Circle class and store it instances of that in an ArrayList.) Then to draw your scene, just iterate over your data structure and draw all of your circles.
Another option is to use an off-screen PGraphics buffer.

How come this AffineTransform rotation method works?

Ive been programming a game just to become better at java. I had been having alot of trouble with getting the player rotation to work correctly. My first method used this
g2.setTransform(AffineTransform.getRotateInstance(radAngle,x_pos + (img.getWidth() / 2),y_pos+(img.getHeight() / 2)));
However this caused all images to rotate with the player thus making shooting and aiming completely disfunctional.
i was researching and saw someone use this code to make they're player rotate.
Graphics2D g2 = (Graphics2D)g;
AffineTransform oldTransform = g2.getTransform();
AffineTransform newOne = (AffineTransform)(oldTransform.clone());
newOne.rotate(radAngle,x_pos + (img.getWidth() / 2),y_pos+ (img.getHeight() / 2));
g2.setTransform(newOne);
g2.drawImage(img, x_pos,y_pos,this);
repaint();
g2.setTransform(oldTransform);
This works great and i dont have the same problems i had before. However i dont know why.
Heres my full code. The code above is for the body of the paint method.

Here are the images I'm using:

This makes sense since if you don't reset the Graphics object's AffineTransform back to its baseline, it will use the new transform to draw everything including all images. I don't understand however why you have a call to repaint() from within your paint method. You shouldn't do this.

The AffineTransform object is connected to the Graphics2D object via the call to setTransform. Once connected, the transform causes every object drawn using the Graphics2D object to be drawn with that same transform (in this case, rotation) applied to it until a new AffineTransform is assigned to the Graphics2D object via another call to setTransform. The sample code you found saved the old transform (which presumably encodes a normal, non-rotated state) via
AffineTransform oldTransform = g2.getTransform();
The code then created the rotation transform and connected it to the Graphics2D (now all objects drawn would be rotated until a new transform be assigned), then drew the one object that needed to be drawn rotated (which therefore had the newly-created rotation transform applied to it), and then restored the original, non-rotating transform to the Graphics2D object via:
g2.setTransform(oldTransform);
That way, the transform that would be applied to subsequent objects would be the original, non-rotating transform.
