05 - Checkpoint: 1

Recap

So far we've learned about VSCode, GitHub, Java, and OOP. In this checkpoint, you will put these skills to practice.

In this checkpoint, you will be implementing a simulation of pong!

Task

• Create a class Shape.java

  • float x - the x position of the shape

  • float y - the y position of the shape

  • float width - the width of the shape

  • float height - the height of the shape

  • float xSpeed - the x velocity of the shape

  • float ySpeed - the y velocity of the shape

  • public void update() - updates the position of the shape using Euler's Method. This method should also consider any collisions

• Create a class called Paddle.java

  • public Paddle(Ball ball) - constructor should take a reference to the game ball
  • public void update() - overrides the Shape class. Constrain movement to only vertical movement

• Create a class called Ball.java

  • public Ball(int fieldWidth, int fieldHeight)

  • public void update() - overrides the Shape class. Move the ball across the field, and consider collisions with the width and height of the field.

  • public int scored() - checks if the ball entered a goal area. Reset the ball to the center if scored. Return 0 for no score, 1 for X player score and -1 for Y player score.

  • public void xCollide() - should invert xSpeed

  • public void yCollide() - should invert ySpeed

• Create a class called Game.java

  • float windowWidth

  • float windowHeight

  • float scoreX

  • float scoreY

  • float windowWidth

  • float windowHeight

  • Ball ball

  • Paddle leftPaddle

  • Paddle rightPaddle

  • public void start() - should instantiate all game objects

  • public void run() - should call ball & paddle updates and if ball was scored.
