使用Python+pygame贪吃蛇小游戏
使用第三方库pygame，关于Python中pygame游戏模块的安装使用可见 https://blog.csdn.net/cnds123/article/details/119514520
给出两种实现。
第一种
运行效果如下：
游戏源码如下：
import pygame
import sys
import random
# 初始化pygame
pygame.init()
# 设置屏幕大小
screen_size = (640, 480)
screen = pygame.display.set_mode(screen_size)
# 设置游戏标题
pygame.display.set_caption("贪吃蛇：按p键暂停/继续")
# 定义颜色
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)
# 蛇的初始位置
snake_pos = [[100, 100], [80, 100], [60, 100]]
# 食物的初始位置
food_pos = [300, 300]
# 蛇的初始速度
snake_speed = [20, 0]
# 初始化分数
score = 0
# 创建字体对象
font = pygame.font.Font(None, 36)
# 游戏暂停标志
paused = False
# 主循环
while True:
# 处理游戏事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_p: # 按 P 键暂停或继续
paused = not paused
if not paused:
if event.key == pygame.K_UP and snake_speed != [0, 20]:
snake_speed = [0, -20]
elif event.key == pygame.K_DOWN and snake_speed != [0, -20]:
snake_speed = [0, 20]
elif event.key == pygame.K_LEFT and snake_speed != [20, 0]:
snake_speed = [-20, 0]
elif event.key == pygame.K_RIGHT and snake_speed != [-20, 0]:
snake_speed = [20, 0]
if not paused:
# 更新蛇的位置
snake_pos.insert(0, [snake_pos[0][0] + snake_speed[0], snake_pos[0][1] + snake_speed[1]])
# 检查蛇头是否碰到墙壁，如果是则“经过墙壁”
if snake_pos[0][0] < 0:
snake_pos[0][0] = screen_size[0]-20
elif snake_pos[0][0] >= screen_size[0]:
snake_pos[0][0] = 0
elif snake_pos[0][1] < 0:
snake_pos[0][1] = screen_size[1]-20
elif snake_pos[0][1] >= screen_size[1]:
snake_pos[0][1] = 0
# 检查蛇头是否碰到食物
if snake_pos[0] == food_pos:
food_pos = [random.randrange(1, screen_size[0] // 20) * 20, random.randrange(1, screen_size[1] // 20) * 20]
score += 1 # 计分
else:
snake_pos.pop()
# 绘制游戏界面
screen.fill(WHITE)
for pos in snake_pos:
pygame.draw.rect(screen, GREEN, pygame.Rect(pos[0], pos[1], 20, 20))
pygame.draw.rect(screen, RED, pygame.Rect(food_pos[0], food_pos[1], 20, 20))
# 显示得分
score_text = font.render("Score: " + str(score), True, (0, 0, 0))
screen.blit(score_text, (10, 10))
# 如果游戏暂停，则显示暂停提示
if paused:
pause_text = font.render("Paused. Press P to continue.", True, (0, 0, 0))
screen.blit(pause_text, (screen_size[0] // 2 - pause_text.get_width() // 2, screen_size[1] // 2 - pause_text.get_height() // 2))
pygame.display.flip() # 更新屏幕显示
# 控制游戏速度
pygame.time.Clock().tick(6)
第二种
就不给出运行效果图了，你可以运行看看。
