import pygame

初始化pygame

pygame.init()

定义颜色

white = (255, 255, 255)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)

设置显示窗口

dis_width = 800
dis_height = 600
dis = pygame.display.set_mode((dis_width, dis_height))
pygame.display.set_caption('贪吃蛇游戏 by Python')

设置游戏时钟

clock = pygame.time.Clock()

蛇的大小和速度

snake_block = 10
snake_speed = 15

设置字体 - 确保使用系统存在的字体

try:
font_style = pygame.font.SysFont("arial", 25)
score_font = pygame.font.SysFont("arial", 35)
except:
font_style = pygame.font.SysFont(None, 25)

"""显示当前得分"""

"""绘制蛇"""
