Question

Need help with a problem using Processing language:

ClassAssignment2.zip includes 4 files (copy/paste them):

ClassAssignment2:

ArrayList<BouncingBall> bouncingList;
ArrayList<OrbitBall> orbitList;
ArrayList<Car> carList;

void setup()
{
size(500, 500);
bouncingList = new ArrayList<BouncingBall>();
orbitList = new ArrayList<OrbitBall>();
carList = new ArrayList<Car>();
  
bouncingList.add(new BouncingBall(random(100, width-100), random(100, height-100), new PVector(random(-2, 2), random(-2, 2))));
orbitList.add(new OrbitBall(random(0, 0.1), random(100, width-100), random(100, height-100), random(10, 100)));
carList.add(new Car(random(100, width-100), random(100, height-100), random(1, 5)));
  
}

void draw()
{
background(200);
  
for(int i = 0; i < bouncingList.size(); i++)
{
BouncingBall b = bouncingList.get(i);
b.Update();
}
for(int i = 0; i < orbitList.size(); i++)
{
OrbitBall b = orbitList.get(i);
b.Update();
}
for(int i = 0; i < carList.size(); i++)
{
Car c = carList.get(i);
c.Update();
}
}

BouncingBall:

class BouncingBall
{
float x,y,w,h;
PVector speed;
  
BouncingBall(float inX, float inY, PVector inSpeed)
{
x = inX;
y = inY;
w = 25;
h = 25;
speed = inSpeed;
}
  
void Update()
{
x += speed.x;
y += speed.y;
  
if(x - w/2 < 0 || x + w/2 > width)
{
speed.x *= -1;
}
if(y - h/2 < 0 || y + h/2 > height)
{
speed.y *= -1;
}
  
fill(0, 255, 0);
ellipse(x, y, w, h);
}
  
}

Car:

class Car
{
float x,y,w,h;
float speedX;
  
Car(float inX, float inY, float inSpeedX)
{
x = inX;
y = inY;
w = 50;
h = 20;
speedX = inSpeedX;
}
  
void Update()
{
x += speedX;

if(x > width)
{
x = 0 - w;
}
  
fill(255, 0, 0);
rect(x, y, w, h);
fill(0);
ellipse(x, y, 10, 10);
ellipse(x+w, y, 10, 10);
ellipse(x, y+h, 10, 10);
ellipse(x+w, y+h, 10, 10);
}
}

OrbitBall:

class OrbitBall
{
float x,y,w,h;
float angle;
float speed;
float orbitX, orbitY;
float distance;

OrbitBall(float inSpeed, float inOrbitX, float inOrbitY, float inDistance)
{
x = 0;
y = 0;
w = 25;
h = 25;
distance = inDistance;
speed = inSpeed;
orbitX = inOrbitX;
orbitY = inOrbitY;
}

void Update()
{
angle -= speed;
  
x = orbitX + (distance * cos(angle));
y = orbitY + (distance * sin(angle));
  
fill(0, 0, 255);
ellipse(x,y,w,h);

}
}

You will clean and improve the code through inheritance. You will create a base abstract Gameobject class for the BouncingBall, Car, OrbitBall to inherit from. Follow the example we did in class for reference. Download the zip file called ClassAssignment2.zip to start. Requirements: You MUST to implement the following requirements to your inheritance assignment GameObject Class o Must be an abstract class o Has abstract method called update Ball Class o Must be an abstract class o nherits (extends) from GameObject Other: The Bouncing Ball and OrbitBall must inherit (extends) from Ball class, o Ball inherits from GameObject o This means BouncingBall is of type BouncingBall, Ball, and GameObject Car must inherit (extends) from Gameobject All derived class (Orbit, Bouncing, Car) must implement the method Update()

#include<dos.h>
#include<iostream.h>
#include<graphics.h>
#include<math.h>
#include<conio.h>
void main()
{
int d=DETECT,m;
initgraph(&d,&m,"e: ccgi");
float x=1,y=0.00000,j=.5,count=.1;
float r=15;
setcolor(10);
line(0,100,150,350);
sleep(1);
for(int k=0;k<=7;k++)
{
for(float i=90;i<400;i+=10)
{
   y=cos(((i*22/7)/170))/j;
   if(y>0)
   y=-y;
   x+=5;
   setcolor(10);
   setfillstyle(1,10);
   circle(x,y*100+200,r);
   floodfill(x,y*100+200,14);
delay(100);
   setcolor(0);
   setfillstyle(1,0);
   circle(x,y*100+150,r);
   floodfill(x,y*100+150,0);
}
j+=count;
count+=.1;
}
getch();
}
