HW #17

[chasestarr]

_In this homework we will practice applying forces. Look at these three videos to go over forces again. Here is a link to the basic mover class if you need it._

Create at least 20 objects with mass on the screen that are constantly affected by a gravity force. When the mouse is pressed down, a secondary force will be applied to the objects. You will need to use for loops to complete this homework. Take a look at week16 image notes here

Please paste your code as a comment on this post

Mr chase tell me if this is what you want.

Mover[] ball;

void setup(){ size(800,800); ball = new Mover[20]; for (int i = 0; i < ball.length; i++){ ball[i] = new Mover(); println("index"+i + " is " +ball[i]); } }

void draw(){ background(0);

for (Mover m : ball) {

PVector gravity = new PVector(0,0.01,10); m.applyForce(gravity);

if(mousePressed){ PVector wind = new PVector(0.02,0); m.applyForce(wind); } m.update(); m.display(); m.checkEdges();

} }

}

void display(){ stroke(0); fill(255); ellipse(location.x,location.y,20,20); float[]nums=new float[50];

}

void update(){ velocity.add(acceleration); location.add(velocity); acceleration.mult(0); velocity.limit(1000);

Tab one

Mover[] ball;

void setup(){
  size(800, 800);
  ball = new Mover[20];
  for (int i = 0; i<ball.length; i++){
    ball[i] = new Mover();
    println("index"+i + " is " +ball[i]);
  }
}
  void draw(){
    background(0);

    for(Mover a: ball){

      PVector gravity = new PVector(0,0.01,10);
      a.applyForce(gravity);

      if(mousePressed){
        PVector wind = new PVector(0,0.01,10);
        a.applyForce(wind);
      }

      a.update();
      a.display();
      a.checkEdges();
    }
  }
Tab two

class Mover {
  PVector location;
  PVector velocity;
  PVector acceleration;

  Mover() {
    location = new PVector(random(width), random(height));
    velocity = new PVector(random(-2, 2), random(-2, 2));
    acceleration = new PVector(0.001, -0.001);
  }

  void display() {
    stroke(0);
    fill(110, 115, 0);
    ellipse(location.x, location.y, 30, 30);
    float[]nums=new float[50];
  }

  void update() {
    velocity.add(acceleration);
    location.add(velocity);
    acceleration.mult(0);
    velocity.limit(1000);
  }

  void applyForce(PVector force){
  acceleration.add(force);
  }

void checkEdges(){
if(location.x > width){
location.x = 0;
} else if(location.x < 0){
location.x = width;
}
if(location.y > height){
location.y = 0;
} else if(location.y < 0){
location.y = height;
}
}
}

We're downstairs waiting for someone to open the door.
