I'm having trouble getting a "bullet/projectile" to be created at a dynamic location. In the below code, the projectiles are the bubbles of the Bubble class and is created using an array. The object should be created at the x and y coordinates of the otter (in the Otter class), but instead they are generated at what appears to be (0,0). Any suggestions?

Code:

Bubble[] bubbles = new Bubble[100];

Otter otter;

int bubCount = 0;

void setup() {
  size(500,500);
  background(255);
  smooth();
  noCursor();

  otter = new Otter(color(0), 20, 50, 5, 3);

  for (int i = 0; i < bubbles.length; i++) {
    bubbles[i] = new Bubble();
  }
}

void draw() {
  background(255);
  
  println(otter.x + " " + otter.y);

  otter.display();
  otter.setLocation(mouseX,mouseY);

  for (int i = 0; i < bubbles.length; i++) {
    bubbles[i].move();
    bubbles[i].display();
    if (i == bubbles.length) {
	i = 0;
    }
  }
}

void mouseClicked() {
  bubbles[bubCount].alive = true;

  if (bubCount >= bubbles.length - 1) {
    bubCount = 0;
  }

  bubCount++;
}


class Bubble {

  color c;
  int r;
  int speedX;
  int x;
  int y;
  boolean alive;

  Bubble() {
    r = 5;
    x = otter.x;
    y = otter.y;
    c = color(107,184,234);
    speedX = 5;
    alive = false;
  }

  void display() {
    if (alive) {
	stroke(0);
	fill(c);
	ellipse(x,y,r,r);
    }
  }

  void move() {
    if (alive) {
	x = x + speedX;
    }
  }

}


class Otter {

  color furColor;
  int h;
  int w;
  int x;
  int y;
  int speedX;
  int speedY;

  Otter(color tempColor, int tempH, int tempW, int tempSpeedX, int tempSpeedY) {
    furColor = tempColor;
    h = tempH;
    w = tempW;
    speedX = tempSpeedX;
    speedY = tempSpeedY;
  }

  void display() {
    noStroke();
    fill(furColor);
    rectMode(CENTER);
    rect(x,y,w,h);
  }

  void setLocation(int tempX, int tempY) {
    x = tempX;
    y = tempY;
  }
}
 

The println function shows that the otter.x and otter.y variables are being updated, but the coordinates of the bubbles don't seem to change.

You the man
