Week 1: Introduction to Python and Game Development Basics


Class 1: Python Basics and Pygame Setup

1.1 Python Basics

1.1.1 Variables and Data Types

  • Variables are containers for storing data values.
  • Data types include integers (int), floating-point numbers (float), strings (str), and booleans (bool).

Example:

# Integer
score = 10

# Float
player_speed = 2.5

# String
player_name = "Chukwudi"

# Boolean
game_over = False
Enter fullscreen mode Exit fullscreen mode

1.1.2 Loops

  • Loops are used to repeat a block of code multiple times.
  • Common loops include for loops and while loops.

Example:

# For loop
for i in range(5):
    print("Hello", i)

# While loop
countdown = 5
while countdown > 0:
    print("Countdown:", countdown)
    countdown -= 1
Enter fullscreen mode Exit fullscreen mode

1.1.3 Functions

  • Functions are reusable blocks of code that perform a specific task.

Example:

def greet_player(name):
    print("Welcome,", name)

greet_player(player_name)
Enter fullscreen mode Exit fullscreen mode

1.2 Pygame Setup

1.2.1 Installing Pygame

  • To install Pygame, use the following command:
pip install pygame
Enter fullscreen mode Exit fullscreen mode

1.2.2 Initializing Pygame

  • Pygame is a Python library used for creating games.
  • To initialize Pygame and create a game window, use the following code:

Example:

import pygame

# Initialize Pygame
pygame.init()

# Create a game window
screen = pygame.display.set_mode((800, 600))

# Set window title
pygame.display.set_caption("My First Game")

# Main game loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

# Quit Pygame
pygame.quit()
Enter fullscreen mode Exit fullscreen mode

1.3 Mini Project: Simple Drawing App

Goal: Create a basic app that allows users to draw on the screen with the mouse.

1.3.1 Code Example

import pygame

# Initialize Pygame
pygame.init()

# Set up the screen
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Drawing App")

# Colors
white = (255, 255, 255)
black = (0, 0, 0)

# Set background color
screen.fill(white)

# Main loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEMOTION:
            if event.buttons[0]:  # Left mouse button is pressed
                pygame.draw.circle(screen, black, event.pos, 5)

    pygame.display.flip()

pygame.quit()
Enter fullscreen mode Exit fullscreen mode

1.4 Exercises

  1. Modify the Drawing App:

    • Change the color of the brush to red.
    • Allow the user to toggle between different brush sizes using the keyboard.
  2. Create Shapes:

    • Use keyboard inputs to draw different shapes like circles and rectangles on the screen.

Class 2: Understanding Game Components

2.1 Sprites and Surfaces in Pygame

2.1.1 Sprites

  • Sprites are objects in a game, such as characters or items. They can move, interact, and have their own properties.

2.1.2 Surfaces

  • Surfaces are images or sections of the screen that can be manipulated.

Example:

# Load an image and create a sprite
player_image = pygame.image.load("player.png")
player_rect = player_image.get_rect()

# Draw the sprite on the screen
screen.blit(player_image, player_rect)
Enter fullscreen mode Exit fullscreen mode

2.2 Handling User Input

2.2.1 Keyboard Input

  • Detecting key presses can be done using pygame.event and pygame.key.get_pressed().

Example:

for event in pygame.event.get():
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            print("Left arrow key pressed")
Enter fullscreen mode Exit fullscreen mode

2.2.2 Mouse Input

  • Detecting mouse movements and clicks is similar to keyboard input.

Example:

for event in pygame.event.get():
    if event.type == pygame.MOUSEBUTTONDOWN:
        print("Mouse button clicked at", event.pos)
Enter fullscreen mode Exit fullscreen mode

2.3 Basic Collision Detection

2.3.1 Rectangular Collisions

  • Collisions between objects are often detected using rectangles.

Example:

# Check if two rectangles overlap
if player_rect.colliderect(other_rect):
    print("Collision detected!")
Enter fullscreen mode Exit fullscreen mode

2.4 Mini Project: Catch the Ball

Goal: Create a game where a ball falls from the top of the screen, and the player must catch it with a paddle.

2.4.1 Code Example

import pygame
import random

# Initialize Pygame
pygame.init()

# Screen setup
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Catch the Ball")

# Colors
white = (255, 255, 255)
black = (0, 0, 0)

# Player (Paddle)
paddle = pygame.Rect(350, 550, 100, 10)

# Ball
ball = pygame.Rect(random.randint(0, 750), 0, 50, 50)
ball_speed = 5

# Main game loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # Move paddle with arrow keys
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and paddle.left > 0:
        paddle.move_ip(-5, 0)
    if keys[pygame.K_RIGHT] and paddle.right < 800:
        paddle.move_ip(5, 0)

    # Move ball down
    ball.move_ip(0, ball_speed)

    # Check for collision
    if ball.colliderect(paddle):
        print("Caught!")
        ball.topleft = (random.randint(0, 750), 0)

    # Redraw screen
    screen.fill(white)
    pygame.draw.rect(screen, black, paddle)
    pygame.draw.ellipse(screen, black, ball)
    pygame.display.flip()

pygame.quit()
Enter fullscreen mode Exit fullscreen mode

2.5 Exercises

  1. Add Scoring:

    • Keep track of how many balls the player catches and display the score on the screen.
  2. Increase Difficulty:

    • Gradually increase the speed of the ball as the player catches more balls.

This concludes Week 1. you (students) should now be comfortable with Python basics, Pygame setup, and creating simple interactive games. I encourage you to experiment with the exercises to deepen your understanding.
