Get started with pygame quickly: simple installation guide and getting started with game programming

Concise Tutorial: Install pygame easily and start game programming quickly

Introduction: pygame is a Python module used to develop games. It provides a series of simple and easy-to-use Functions and tools make it easier for developers to create their own games. This article will guide readers to easily install pygame and provide code examples to quickly start game programming practice.

1. Install pygame

Installing pygame only requires a few simple steps:

1. Open a terminal or command prompt window.
2. Enter the following command on the command line to install pygame:

pip install pygame

This command will automatically download and install the latest version of pygame.

2. Create a game window

The following is a simple sample code for creating a game window named "My First Game":

import pygame

# 初始化 pygame
pygame.init()

# 设置窗口尺寸
size = (800, 600)
screen = pygame.display.set_mode(size)

# 设置窗口标题
pygame.display.set_caption("My First Game")

# 主循环
done = False
clock = pygame.time.Clock()

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

    # 渲染代码
    screen.fill((255, 255, 255))

    # 更新渲染
    pygame.display.flip()

    # 控制帧率
    clock.tick(60)

# 退出游戏
pygame.quit()

Parsing code:

• Line 3: Import the pygame module.
• Line 6: Initialize pygame.
• Line 9-11: Set the size of the game window.
• Line 14: Set the title of the game window.
• Line 17-29: Main loop, used to listen for events, render the picture and control the frame rate.
• Line 31: Exit pygame and release resources.

3. Drawing images and processing input

pygame provides many functions and tools for drawing images and processing input, allowing developers to easily implement various game functions.

The following is a simple example showing how to use pygame to draw a moving ball and obtain keyboard input sample code:

import pygame

# 初始化 pygame
pygame.init()

# 设置窗口尺寸
size = (800, 600)
screen = pygame.display.set_mode(size)

# 设置窗口标题
pygame.display.set_caption("My Game")

# 加载图像
ball_image = pygame.image.load("ball.png")

# 设置球的初始位置和速度
ball_x = 400
ball_y = 300
ball_speed_x = 0
ball_speed_y = 0

# 主循环
done = False
clock = pygame.time.Clock()

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

        # 获取键盘输入
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP:
                ball_speed_y = -5
            elif event.key == pygame.K_DOWN:
                ball_speed_y = 5
            elif event.key == pygame.K_LEFT:
                ball_speed_x = -5
            elif event.key == pygame.K_RIGHT:
                ball_speed_x = 5

        if event.type == pygame.KEYUP:
            if event.key == pygame.K_UP or event.key == pygame.K_DOWN:
                ball_speed_y = 0
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                ball_speed_x = 0

    # 更新球的位置
    ball_x += ball_speed_x
    ball_y += ball_speed_y

    # 渲染代码
    screen.fill((255, 255, 255))
    screen.blit(ball_image, (ball_x, ball_y))

    # 更新渲染
    pygame.display.flip()

    # 控制帧率
    clock.tick(60)

# 退出游戏
pygame.quit()

Parsing code:

• Line 14: Load the image of the ball.
• Lines 18-22: Get keyboard input and change the ball's speed based on the input.
• Lines 26-30: Update the ball’s position based on its speed.
• Line 34: Use the blit() function to draw the ball to the screen.

Summary:

Through the introduction and code examples of this article, readers can easily install pygame and start practicing game programming. Not only that, pygame also provides richer features, such as sprites, collision detection, audio, etc., which can make game development more interesting and efficient. I hope readers can use pygame to unleash their creativity and create their own wonderful game works!
