GREAT!

We will be creating lots of
new and different games

B

Breakout game

B

Complex game! Let's break it down

B

  • The paddle can be used to direct the motion of a ball.

  • The player has to guide the ball to collide with a stationary brick wall to destroy the brick and gain points.

  • If the player fails to catch the ball using the paddle, the game ends

  • The player can move a paddle left/right by pressing the arrow keys on the keyboard.

Integrated development environment (IDE)

Python + Spyder

B

B

Pygame Library

B

import pygame

Step 1: Download and install the "pygame" library

Step 2: Create a new file in Spyder and save it as "breakout.py"

Step 3: Import the "pygame" library to your code

B

Step 4: Initialize the "pygame"

Step 5: Use "pygame" to create a window

Output: 

import pygame

pygame.init()
import pygame

pygame.init()
screen = pygame.display.set_mode((400,600))

B

Step 6: Add a game loop

Output:

import pygame

pygame.init()

screen = pygame.display.set_mode((400,600))

while True:    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

B

Coordinate system in pygame

y

x

500

width

height

pygame.Rect(200,500,30,10)

x

y

width

height

0,600

400,0

400,600

0,0

200

(10)

(30)

B

Step 7: Use "pygame.Rect()" to make a rectangle

import pygame

pygame.init()

screen = pygame.display.set_mode((400,600))

paddle=pygame.Rect(200,500,30,10)

while True:    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

B

Guess why character
is not displayed?

B

pygame.draw.rect(surface, color, rect)

Drawing !

B

(Red, Green, Blue)
Red color -> (255, 0, 0)

B

Step 8: Draw the rectangle on the screen

Step 9: Update the screen

import pygame

pygame.init()

screen = pygame.display.set_mode((400,600))

paddle=pygame.Rect(200,500,30,30)

while True:    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
            
    pygame.draw.rect(screen,(23,100,100),paddle)
    
    pygame.display.update()

B

Output :

B

Student activity

Student activity

Hints:

Create the rectangle object: pygame.Rect

Draw the created rectangle: pygame.draw.rect

B

Step 10: Create another rectangle named "ball" and draw it on the screen

import pygame

pygame.init()

screen = pygame.display.set_mode((400,600))

paddle=pygame.Rect(200,500,30,30)
ball=pygame.Rect(70,50,10,10)

while True:    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
            
    pygame.draw.rect(screen,(23,100,100),paddle)
    pygame.draw.rect(screen,(255,255,255),ball)
    
    pygame.display.update()

What will be the output of the following code:


B

Color,Surface,Rect

Surface,Color,Rect

Rect,Color,Surface

Q.1

A

Surface,Color,Rect

B

C

We first pass the surface, then the color, and then the name of the rectangle

What does RGB stand for?

B

Red-grey-blue

Red-green-blue

Red-green-black

Q.2

A

Red-green-blue

B

C

RGB stands for red green blue. Each color that we use can be represented as a combination of these 3 colors in varying percentages.

B

Student activity

SAA 1

Hints:

Create the rectangle object: pygame.Rect

Draw the created rectangle: pygame.draw.rect

RGB for orange:255,69,0

Creation of Orange ball

B

Create another rectangle named "ball" and draw it on the screen

import pygame

pygame.init()

screen = pygame.display.set_mode((400,600))

paddle=pygame.Rect(200,500,30,30)
ball=pygame.Rect(70,50,10,10)

while True:    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
            
    pygame.draw.rect(screen,(23,100,100),paddle)
    pygame.draw.rect(screen,(255,69,0),ball)
    
    pygame.display.update()
