About the game

This is a clone of the classic Brick Breaker game for the terminal with some extra features. The objective is to destroy bricks by smashing them with a bouncing ball in the shortest possible time without running out of lives. The ball is bounced off a paddle which the player can move left and right. A life is lost when the ball touches the ground below the paddle.

Rules

• There are 3 levels in the game. The last level of the game has a boss enemy
• The player gets 3 lives. If the ball touches the ground below the paddle, the player loses a life. The game ends in a loss if the player loses all lives.
• The score is calculated as score = 10 * number of bricks destroyed - 0.5 * time(in seconds)
• Whenever a brick is destroyed, a powerup may appear with a certain probability. The effect of the powerup lasts for 20 seconds.
• Powerups include:
  • X - Increasing length of paddle
  • ~ - Decreasing length of paddle
  • # - Making the ball stick to the paddle every time it is caught
  • > - Increasing the speed of the ball
  • ^ - Through ball - Making the ball pass through every brick and destroying it
  • * - Doubling the number of balls
  • T - Shoot lasers from paddle. Lasers affect bricks
• After a certain amount of time, the whole ensemble of bricks starts moving down towards the player on every ball touch. If the bricks reach the player, then it is game over.

How to play

• A/D keys move the paddle left and right
• When a ball is stuck to the paddle, release by pressing R
• Quit the game at any time by pressing Q
• To shoot lasers, press X
• To skip a level, press S

Features

Bricks

• Bricks have 4 strength levels. The highest strength level is unbreakable.
• There is also a rainbow brick which changes strength levels continuosly.

Boss

• The boss follows the players movements and drops bombs on the player every 5 seconds.
• The boss has a health which can be reduced by hitting it with the ball
• When the health reaches 3 or 1, the boss builds a wall of bricks to protect itself.
• When the health reaches 0, the boss dies.

This game is built using OOP concepts. Each entity in the game is an object instance of an underlying class.

• Abstraction is incorporated by creating functions with semantic names such as bounce_on, move, etc which hide away the implemetation details.
• As all entities are instances of some class which includes both the relevant data variables for the entity as well as methods acting on the entity, encapsulation is involved.
• Inheritance is showcased in the case of different powerup classes inheriting from a base powerup class.
• Polymorphism is seen in the case of different powerup classes having their own unique activate and deactivate functions. The move method is also defined on multiple classes but has a different functionality in each.
