Python Game Development: Building Your First Mini-Game from Scratch-Jade Branch Data

Hello, dear Python enthusiasts! Today let's talk about an exciting topic — how to develop games with Python. Sounds exciting, right? Don't worry, even if you're new to programming, just follow my lead, and soon you'll be creating your own mini-game world.

Why Choose Python?

When it comes to game development, you might think of "big" languages like C++ or Java. So why are we choosing Python? Let me give you a few compelling reasons:

Easy to Learn: Python's syntax is simple and clear, as natural as having a conversation in English. You don't have to spend a lot of time understanding complex syntax rules, allowing you to focus more on implementing game logic.
Rich Library Support: Python has powerful game development libraries like Pygame and Arcade. These libraries are like "treasure chests" ready for you to use with various tools.
Rapid Prototyping: With Python, you can quickly see results when writing games. This immediate feedback is especially suitable for beginners, keeping your enthusiasm and motivation for learning high.
Cross-Platform Compatibility: Games developed with Python can easily run on Windows, Mac, and Linux, saving you the trouble of adapting to different systems.
Active Community Support: When you encounter problems, you can always find enthusiastic partners in the Python community to help you. It's like having a 24/7 "tech advisor" team, isn't that great?

Preparing the Development Environment

Before we start coding, we need to prepare our "weapons." You need to install the following tools:

Python Interpreter: Download the latest version of Python from the official website. Remember to check the "Add Python to PATH" option during installation.
Code Editor: I recommend using VSCode or PyCharm, as they have powerful code completion and debugging features that greatly improve your development efficiency.
Pygame Library: Open the command line and enter pip install pygame to easily install this powerful game development library.

With these ready, we can start our game development journey!

First Experience with Pygame

Pygame is one of the most popular libraries in Python game development. It provides rich features that allow us to easily handle graphics, sound, and user input. Let's create the simplest game window with Pygame to feel its magic:

import pygame


pygame.init()


screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("My First Pygame Window")


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

    # Fill background color
    screen.fill((255, 255, 255))  # White background

    # Update screen display
    pygame.display.flip()


pygame.quit()

Run this code, and you'll see a white game window. Isn't it amazing? This is the starting point of your game world!

Adding Game Elements

With the window set up, let's add some simple game elements, such as a moving ball:

import pygame

pygame.init()


width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Bouncing Ball")


BLACK = (0, 0, 0)
RED = (255, 0, 0)


ball_radius = 20
ball_x = width // 2
ball_y = height // 2
ball_speed_x = 5
ball_speed_y = 5

clock = pygame.time.Clock()

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

    # Move the ball
    ball_x += ball_speed_x
    ball_y += ball_speed_y

    # Detect collision
    if ball_x <= ball_radius or ball_x >= width - ball_radius:
        ball_speed_x = -ball_speed_x
    if ball_y <= ball_radius or ball_y >= height - ball_radius:
        ball_speed_y = -ball_speed_y

    # Draw
    screen.fill(BLACK)
    pygame.draw.circle(screen, RED, (int(ball_x), int(ball_y)), ball_radius)

    pygame.display.flip()
    clock.tick(60)  # Limit frame rate to 60fps

pygame.quit()

Look! Now we have a little red ball bouncing around on the screen. Doesn't it feel rewarding?

Adding Interaction

The most exciting part of games is interaction. Let's add keyboard control to the ball:

import pygame

pygame.init()

width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Control the Ball")

BLACK = (0, 0, 0)
RED = (255, 0, 0)

ball_radius = 20
ball_x = width // 2
ball_y = height // 2
ball_speed = 5

clock = pygame.time.Clock()

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

    # Get key states
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        ball_x -= ball_speed
    if keys[pygame.K_RIGHT]:
        ball_x += ball_speed
    if keys[pygame.K_UP]:
        ball_y -= ball_speed
    if keys[pygame.K_DOWN]:
        ball_y += ball_speed

    # Keep the ball within the screen
    ball_x = max(ball_radius, min(width - ball_radius, ball_x))
    ball_y = max(ball_radius, min(height - ball_radius, ball_y))

    # Draw
    screen.fill(BLACK)
    pygame.draw.circle(screen, RED, (int(ball_x), int(ball_y)), ball_radius)

    pygame.display.flip()
    clock.tick(60)

pygame.quit()

Now, you can use the arrow keys to control the ball's movement. Isn't the game more interesting now?

Advanced Game Logic

Next, let's go a step further and add some more complex game logic. For example, we can create a simple "dodge obstacles" game:

import pygame
import random

pygame.init()

width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Dodge the Obstacles")

BLACK = (0, 0, 0)
RED = (255, 0, 0)
BLUE = (0, 0, 255)

player_radius = 20
player_x = width // 2
player_y = height - 50
player_speed = 5

obstacle_width = 50
obstacle_height = 50
obstacle_speed = 3
obstacles = []

score = 0
font = pygame.font.Font(None, 36)

clock = pygame.time.Clock()

def create_obstacle():
    x = random.randint(0, width - obstacle_width)
    y = -obstacle_height
    obstacles.append(pygame.Rect(x, y, obstacle_width, obstacle_height))

def draw_obstacles():
    for obstacle in obstacles:
        pygame.draw.rect(screen, BLUE, obstacle)

def move_obstacles():
    for obstacle in obstacles:
        obstacle.y += obstacle_speed
        if obstacle.top > height:
            obstacles.remove(obstacle)
            global score
            score += 1

def check_collision():
    player_rect = pygame.Rect(player_x - player_radius, player_y - player_radius, 
                              player_radius * 2, player_radius * 2)
    for obstacle in obstacles:
        if player_rect.colliderect(obstacle):
            return True
    return False

running = True
game_over = False

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        if event.type == pygame.KEYDOWN and game_over:
            game_over = False
            player_x = width // 2
            player_y = height - 50
            obstacles.clear()
            score = 0

    if not game_over:
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            player_x -= player_speed
        if keys[pygame.K_RIGHT]:
            player_x += player_speed

        player_x = max(player_radius, min(width - player_radius, player_x))

        if random.randint(1, 60) == 1:
            create_obstacle()

        move_obstacles()

        if check_collision():
            game_over = True

    screen.fill(BLACK)

    if not game_over:
        pygame.draw.circle(screen, RED, (int(player_x), int(player_y)), player_radius)
        draw_obstacles()
        score_text = font.render(f"Score: {score}", True, (255, 255, 255))
        screen.blit(score_text, (10, 10))
    else:
        game_over_text = font.render("Game Over! Press any key to restart", True, (255, 255, 255))
        screen.blit(game_over_text, (width // 2 - 200, height // 2 - 18))

    pygame.display.flip()
    clock.tick(60)

pygame.quit()

Wow! Now we have a complete mini-game. The player needs to control the ball to move left and right to dodge the falling blocks. You score points for each block you dodge, and the game ends when you hit a block.

The Joy of Game Development
