Python贪吃蛇游戏的示例代码:
import pygame
import time
import random
# 初始化游戏
pygame.init()
# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)
# 定义游戏窗口大小和标题
display_width = 800
display_height = 600
# 创建游戏窗口
gameDisplay = pygame.display.set_mode((display_width, display_height))
pygame.display.set_caption('贪吃蛇')
# 设置游戏时钟
clock = pygame.time.Clock()
# 定义蛇的大小和移动速度
snake_block = 10
snake_speed = 30
# 定义字体样式和大小
font_style = pygame.font.SysFont(None, 30)
score_font = pygame.font.SysFont(None, 50)
# 定义蛇的颜色
snake_color = green
# 显示得分
def your_score(score):
value = score_font.render("得分: " + str(score), True, black)
gameDisplay.blit(value, [0, 0])
# 绘制蛇
def our_snake(snake_block, snake_list):
for x in snake_list:
pygame.draw.rect(gameDisplay, snake_color, [x[0], x[1], snake_block, snake_block])
# 显示消息并重新开始游戏
def message(msg, color):
mesg = font_style.render(msg, True, color)
gameDisplay.blit(mesg, [display_width/6, display_height/3])
# 游戏循环
def gameLoop():
game_over = False
game_close = False
# 蛇的起始位置和长度
x1 = display_width / 2
y1 = display_height / 2
x1_change = 0

snake_List = []
Length_of_snake = 1
# 随机生成食物的位置
foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0

# 游戏主循环
while not game_over:
while game_close == True:
gameDisplay.fill(white)
message("游戏结束,按Q-退出,C-重新开始", red)
your_score(Length_of_snake - 1)
pygame.display.update()
# 游戏结束后的处理
for event in pygame.event.get():
if event.type == pygame.QUIT:
game_over = True
game_close = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_q:

gameLoop()
# 控制蛇的移动
for event in pygame.event.get():
if event.type == pygame.QUIT:

if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x1_change = -snake_block
y1_change = 0
elif event.key == pygame.K_RIGHT:
x1_change = snake_block
y1_change = 0
elif event.key == pygame.K_UP:
y1_change = -snake_block
x1_change = 0
elif event.key == pygame.K_DOWN:
y1_change = snake_block
x1_change = 0
# 边界判断
if x1 >= display_width or x1 < 0 or y1 >= display_height or y1 < 0:
game_close = True
x1 += x1_change
y1 += y1_change
gameDisplay.fill(white)
pygame.draw.rect(gameDisplay, red, [foodx, foody, snake_block, snake_block])
snake_Head = []
snake_Head.append(x1)
snake_Head.append(y1)
snake_List.append(snake_Head)
if len(snake_List) > Length_of_snake:
del snake_List[0]
# 蛇与自己相撞判断
for x in snake_List[:-1]:
if x == snake_Head:
game_close = True
our_snake(snake_block, snake_List)
your_score(Length_of_snake - 1)
pygame.display.update()
# 吃到食物的判断
if x1 == foodx and y1 == foody:
foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0
foody = round(random.randrange(0, display_height - snake_block) / 10.0) * 10.0
Length_of_snake += 1
# 控制帧率
clock.tick(snake_speed)
pygame.quit()
quit()
# 运行游戏
gameLoop()
运行以上代码,即可启动一个贪吃蛇游戏。你可以用方向键控制蛇的移动,吃到食物后蛇的长度会增加,如果蛇撞到边界或者自己,游戏结束。
