HW #13

[chasestarr]

In this homework we will practice reformatting old homework projects to use vectors.

• Take one old homework project and reformat the code to use vectors instead of individual x,y variables.
• Look at Chapter 1 in the Nature of Code online book for help.

Post a link to a Github repository or paste your code below.

PVector position= new PVector(400,400);
PVector velocity= new PVector(1,3.3);
void setup (){
  size(800,800);
  background(0);
}

void draw (){

  position.x= position.x + velocity.x;
  position.y= position.y + velocity.y;
rect(position.x,position.y,50,50);
if((position.x > width) || (position.x < 0)){
  velocity.x = velocity.x *-1;
}
  if((position.y > height) || (position.y < 0)){
    velocity.y = velocity.y *-1;
  }
  }

We're only supposed to do three, correct?

[chasestarr]

@Brandonsugar Only needed to do one, but doing more is good practice! :+1:

[Pummelweed]

PVector position = new PVector(0,500);
PVector positionII = new PVector(500,0);
PVector velocity = new PVector(1,3.3);

void setup(){
  size(1000,1000);
}
void draw(){
  background(234);
  noStroke();
  fill(243,151,203);
  ellipse(position.x,position.y,100,100);

  position.add(velocity);

  if(position.x>1000){
    velocity.x = velocity.x*-2;
  }
    if(position.x<0){
    velocity.x = velocity.x*-1;
  }

  ellipse(position.x,position.y,100,100);
  position.add(velocity);

    velocity.y = velocity.y*-1;

Vector Ball

[GoHawks12]

Tab one

Ball myBall;

void setup() {
  size(1000, 1000);
  myBall = new Ball();
}

void draw() {
  background(200);
  myBall.sideMove();
  myBall.verticalMove();
  myBall.bounce();
  myBall.display();
  myBall.gravity();
}

[GoHawks12]

Tab two

class Ball {
color b;
PVector position = new PVector(width/2, height/2);
PVector velocity = new PVector(3, 4.5);
float gravity;
  Ball() {
    fill(b);
  gravity=0.98;
  }

  void display() {
    stroke(0);
    fill(b);
    ellipse(position.x, position.y, 70, 70);
  }

  void gravity() {
    velocity.y = velocity.y + gravity;
    if (position.y>=950) {
      velocity.y = velocity.y - 0.85;
    }
  }

  void sideMove() {
    position.x = position.x + velocity.x;
  }

  void verticalMove() {
    position.y = position.y + velocity.y;
  }

  void bounce() {
    if (position.x > 950) {
      velocity.x = velocity.x - 0.7;
    }

    if (position.x <=50) {
      velocity.x = velocity.x * -0.75;
    }
  }
}
