Hey all. I'm fairly new to processing and I need some help. I've been working on a mini game for my programming class where you "pop" balloons. It involves arrays and I've gotten everything to show up just fine. My problem is getting them to "pop" when I hover the cursor over them. I'm drawing a blank and need some help figuring out what to put under "void pop()" I'm pretty sure the solution is simple. Here's a link to the assignment directions: http://evc-cit.info/cit020/arrays.html

Here is the code that I have (main tab):

Balloon[] balloon = new Balloon[30];

void setup()
{
  size(400, 400);
  smooth();
  frameRate(20);
  for (int i = 0; i < balloon.length; i++)
  {
    float w = random(20, 46);
    balloon[i] = new Balloon(random(50, 350), random(50, 350),
    w, w + random(5, 11), makeRandomColor());
  }
}

void draw()
{
  background(255);
  for (int i = 0; i < balloon.length; i++)
  {
    balloon[i].display();
    balloon[i].move();
    balloon[i].bounce();
    // balloon[i].hit(); <-- This would go here for the balloon pop
  }
}

color makeRandomColor()
{
  color result = color(
  int(random(128, 255)),
  int(random(128, 255)),
  int(random(128, 255)));
  return result;
}

Here the code for the class:

class Balloon
{
  float w;
  float h;
  float x;
  float y;
  float r;
  float g;
  float b;
  color bColor;
  float HSpeed;
  float VSpeed;

  Balloon(float x, float y, float w, float h, color bColor)
  {
    this.w = w;
    this.h = h;
    this.x = x;
    this.y = y;
    this.bColor = bColor;
    this.HSpeed = int(random(3, 8));
    this.VSpeed = int(random(3, 7));
  }

  void display()
  {
    fill(bColor);
    ellipse(x, y, w, h);
  }

  void move()
  {
    x = x + HSpeed;
    y = y + VSpeed;
  }

  void bounce()
  {
    if (x < 0 + w / 2.0 || x > width - w / 2.0)
    {
      HSpeed = -HSpeed;
    }
    if (y < 0 + h / 2.0 || y > height - h / 2.0)
    {
      VSpeed = -VSpeed;
    }
  }

  boolean hit(int pX, int pY)
  {
    float a = w / 2.0;
    float b = h / 2.0;
    float ex = pX - x; // calculate relative to center of ellipse
    float ey = pY - y;
    float r = (ex * ex) / (a * a) + (ey * ey) / (b * b);
    return (r < 1);
  }

  void pop()
  {
  }
}


I think I should put an "if" statement to set the x and y coordinates of each balloon to -1000 when the cursor touches them but I'm not sure how to go about doing that. Help would be appreciated.
