Python:最简单的贪吃蛇

自己写了个贪吃蛇，代码非常简洁，安装Pygame库后直接拿来食用

代码如下：

import pygame

import random

# 游戏窗口尺寸
window_width = 400
window_height = 400

# 蛇身和食物的尺寸
snake_size = 20
food_size = 20

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)

# 初始化pygame
pygame.init()

# 创建游戏窗口
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("贪吃蛇")

clock = pygame.time.Clock()

# 定义贪吃蛇类
class Snake:
def __init__(self):
self.snake = [(8, 8), (7, 8), (6, 8)]
self.direction = "right"

def move(self):
head = self.snake[0]
x, y = head
if self.direction == "up":
y -= 1
elif self.direction == "down":
y += 1
elif self.direction == "left":
x -= 1
elif self.direction == "right":
x += 1

new_head = (x, y)
self.snake.insert(0, new_head)
self.snake.pop()

def change_direction(self, direction):
if (
(self.direction == "up" and direction != "down") or
(self.direction == "down" and direction != "up") or
(self.direction == "left" and direction != "right") or
(self.direction == "right" and direction != "left")
):
self.direction = direction

def check_collision(self):
head = self.snake[0]
if (
head[0] < 0 or head[0] >= window_width // snake_size or
head[1] < 0 or head[1] >= window_height // snake_size or
head in self.snake[1:]
):
return True
return False

def eat_food(self, food):
head = self.snake[0]
if head == food:
self.snake.append(food)
return True
return False

# 定义食物类
class Food:
def __init__(self):
self.position = self.generate_food()

def generate_food(self):
x = random.randint(0, window_width // snake_size - 1)
y = random.randint(0, window_height // snake_size - 1)
return (x, y)

# 游戏主循环
def game_loop():
game_over = False
snake = Snake()
food = Food()

while not game_over:
for event in pygame.event.get():
if event.type == pygame.QUIT:
game_over = True
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
snake.change_direction("up")
elif event.key == pygame.K_DOWN:
snake.change_direction("down")
elif event.key == pygame.K_LEFT:
snake.change_direction("left")
elif event.key == pygame.K_RIGHT:
snake.change_direction("right")

snake.move()

if snake.check_collision():
game_over = True

if snake.eat_food(food.position):
food.position = food.generate_food()

# 绘制游戏窗口
window.fill(black)

for body in snake.snake:
pygame.draw.rect(window, green, (body[0] * snake_size, body[1] * snake_size, snake_size, snake_size))
pygame.draw.rect(window, red, (food.position[0] * snake_size, food.position[1] * snake_size, food_size, food_size))

pygame.display.update()
clock.tick(10)

pygame.quit()

# 运行游戏循环
game_loop()
