Hello,
I have difficulty with following code in Processing, I don’t know how to make the bar catch the images/objects that are falling from above. Here is the code
float x = 100;
float y = 500;
Balken balken; //One Bar object
Timer timer;
Ball[] ball; //An array of ball objects
int score = 0; //Score Variable
void setup() {
size(800, 600);
smooth();
frameRate(30);
textSize(15);
balken = new Balken(200);
ball = new Ball[1000]; //Create 1000 spots in the array
timer = new Timer(300);
timer.start();
}
void draw() {
background(0);
// Display the catcher
balken.display(); //Balken display
// Check the timer
if (timer.isFinished()) {
// Deal with raindrops
// Initialize one drop
ball[score] = new Ball();
// Increment totalDrops
score ++ ;
// If we hit the end of the array
if (score >= ball.length) {
score = 0; // Start over
}
timer.start();
}
// Move and display all drops
for (int i = 0; i < score; i++ ) {
ball[i].move();
ball[i].display();
if (balken.intersect(ball[i])) {
ball[i].caught();
}
}
}
//class bar
class Balken {
float xSpeed = 0; //Speed in direction X
float ySpeed = 0; //Speed in direction Y
float b, h; //Width and Height
color col; // color
float x, y; // location
Balken(float tempR) {
b = tempR;
h = 10;
col = color(50, 129, 129);
fill(col);
x = 100;
y = 500;
}
void setLocation(float x1, float y1) { //float tempX/Y
x = x1; //tempX
y = y1; //temp Y
}
void display() {
stroke(0);
fill(col);
if ((keyPressed == true) && (key == CODED)) {
if (keyCode == LEFT) {
x--;
} else if (keyCode == RIGHT) {
x++;
}
}
rect(x, y, b, h); //Draw bar
xSpeed *= 0.9; //Drag, so the square doesn't fly off the screen
ySpeed *= 0.9;
}
// A function that returns true or false based on
// if the catcher intersects a raindrop
boolean intersect(Ball d) {
// Calculate distance
float distance = dist(x, y, d.x, d.y);
// Compare distance to sum of radii
if (distance < x + d.x) {
return true;
} else {
return false;
}
}
}
//class ball
class Ball {
float x; //X-Koordinate
float y; //Y-Koordinate
float r; // Radius 10
int yDir = 1; //In which direction does it go to?
float y_speed = random(1, 7);
int score = 0; //Score variable
int leben = 5; //Life,health variable
boolean lost = false; //Display if you lost the game
color c; // Define color ‘c’
PImage image;
Ball() {
image = loadImage(“Goldmuenze.png”);
r = 10; // All raindrops are the same size
x = random(width); // Start with a random x location
y = -r*4; // Start a little above the window
y_speed = random(1, 5); // Pick a random speed
c = color(255, 129, 129); //Color
}
// Move the Ball down
void move() {
// Increment by speed
y+=y_speed;
}
//Check if it hits the bottom
boolean Bodenerreicht() {
//If we go a little beyond the bottom
if (y > height + r*4) {
return true;
} else {
return false;
}
}
//Display the ball
void display() {
//display the ball
fill(c);
noStroke();
for(int i = 2; i < r; i++) {
image(image, x, y, 50, 50);
}
}
//If the drop is caught
void caught(){
//Stop it from moving by setting speed equal to zero
y_speed = 0;
//Set the location to somewhere way off-screen
y= -1000;
}
}
//class timer
class Timer {
int savedTime; // When Timer started
int totalTime; // How long Timer should last
Timer(int tempTotalTime) {
totalTime = tempTotalTime;
}
// Starting the timer
void start() {
// When the timer starts it stores the current time in milliseconds.
savedTime = millis();
}
// The function isFinished() returns true if 5,000 ms have passed.
// The work of the timer is farmed out to this method.
boolean isFinished() {
// Check how much time has passed
int passedTime = millis()- savedTime;
if (passedTime > totalTime) {
return true;
} else {
return false;
}
}
}
