游戏代码

import pygame

初始化pygame

pygame.init()

设置游戏窗口

WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("躲避方块 - 基础游戏示例")

确保中文能正常显示

pygame.font.init()
font = pygame.font.SysFont(["SimHei", "WenQuanYi Micro Hei", "Heiti TC"], 36)

颜色定义

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

玩家类

class Player:
