“玩耍是我们大脑最喜欢的学习方式” - 黛安·阿克曼

游戏开发可以是应用编程技能的一种有趣且有益的方式。 Pygame 是一个流行的 Python 库，它提供了一个简单但功能强大的框架来创建 2D 游戏。在本文中，我们将探讨如何使用 Pygame 构建基本游戏。该项目将向您介绍游戏开发中的关键概念，例如处理用户输入、更新游戏状态和渲染图形。

设置 Pygame

您可以使用 pip 安装 Pygame
pip 安装 pygame

构建代码

我们将创建一个游戏，玩家左右移动篮子以接住掉落的物体。游戏将记录分数，每次捕获物体时分数都会增加。

import pygame
import random
import sys

class CatchTheFallingObjectsGame:
    def __init__(self):
        # Initialize Pygame
        pygame.init()

        # Set up display
        self.width, self.height = 800, 600
        self.window = pygame.display.set_mode((self.width, self.height))
        pygame.display.set_caption("Catch the Falling Objects")

        # Define colors
        self.white = (255, 255, 255)
        self.black = (0, 0, 0)
        self.red = (255, 0, 0)

        # Set up player
        self.player_size = 100
        self.player_pos = [self.width // 2, self.height - 50]
        self.player_speed = 10

        # Set up falling objects

    def draw_elements(self):
