This post is contains code in Processing that I have been working on at home. I am trying to make a Block Breaker game, (move the paddle, bounce the ball off it, break the blocks) and am working on the mechanism for the block disappearing. If you know how to fix it, you can comment in the comment box. I am halfway through this code, so there might be snippets of it that don't do anything. I don't have the code commented, but I'll try to comment on it soon. I can make them disappear, but I need the ball to not bounce into the blocks once their gone, which is hard. Here's the code:
float paddleX;
float paddleY;
float ballX, ballY;
int blocksBroken;
int alive?
Block block1;
Paddle plat;
Ball ball;
void setup(){
size(600,600);
block1 = new Block(0,0);
plat = new Paddle();
ball = new Ball();
background(255);
}
void draw(){
background(255);
block1.display();
block1.die();
ball.ballReset();
plat.display();
ball.display();
ball.move();
}
void keyPressed(){
plat.move();
//ball.paddleRadar();
}
class Ball {
float xSpeed, ySpeed, ballsRandomX, ballsRandomY;
Ball(){
ballX = width/2;
ballY = paddleY - 50;
//ballsRandomX = random(0,8);
//ballsRandomY = random(-8,0);
xSpeed = -5;//ballsRandomX;
ySpeed = -5;//ballsRandomY;
}
void display(){
ellipse(ballX,ballY,30,30);
println(blocksBroken);
}
void move(){
ballX = ballX + xSpeed;
ballY = ballY + ySpeed;
if ((ballX > width) || (ballX < 0)){
xSpeed = xSpeed * -1;
}
if ((ballY > height) || (ballY < 0)){
ySpeed = ySpeed * -1;
}
if (((dist(ballX,ballY,paddleX,paddleY) == paddleX - ballX) && (dist(ballX,ballY,paddleX,paddleY) < 50)) || ((dist(ballX,ballY,paddleX,paddleY) == ballX - paddleX) && (dist(ballX,ballY,paddleX,paddleY) < 50))){
ySpeed = ySpeed * -1;
}
}
void ballReset(){
if(ballY > height){
fill(0,255,0);
ballX = paddleX;
ballY = paddleY - 50;
xSpeed = 5;//ballsRandomX;
ySpeed = height/100 * -1;//ballsRandomY;
}
}
}
class Block{
int blockX;
int blockY;
Block(int tempBlockX, int tempBlockY, string temp){
blockX = tempBlockX;
blockY = tempBlockY;
}
void display() {
rectMode(CORNER);
rect(blockX,blockY,width/25,width/25);
rectMode(CENTER);
}
void die() {
if(dist(blockX,blockY,ballX,ballY) < width/50 + 15) {
int
}
}
}
class Paddle {
Paddle(){
paddleX = width/2;
paddleY = height - 25;
}
void display() {
rectMode(CENTER);
rect(paddleX, paddleY, 100, 8);
fill(170, 0, 250);
}
void move() {
if (key == 'a') {
paddleX = paddleX - width/12;
}
if (key == 'd') {
paddleX = paddleX + width/12;
}
}
}
