可以写哥贪吃蛇代码吗

当然可以，以下是一个简单的贪吃蛇游戏代码（使用Python语言实现）：

import pygame
import random

# 初始化Pygame
pygame.init()

# 定义常量
WIDTH = 600
HEIGHT = 600
GRID_SIZE = 20
GRID_WIDTH = WIDTH // GRID_SIZE
GRID_HEIGHT = HEIGHT // GRID_SIZE
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 创建窗口
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Greedy Snake")

# 定义蛇类
class Snake:
    def __init__(self):
        self.body = [(GRID_WIDTH // 2, GRID_HEIGHT // 2)]
        self.direction = random.choice(['up', 'down', 'left', 'right'])

    def move(self):
        x, y = self.body[0]
        if self.direction == 'up':
            y -= 1
        elif self.direction == 'down':
            y += 1
        elif self.direction == 'left':
            x -= 1
        elif self.direction == 'right':
            x += 1
        self.body.insert(0, (x, y))
        self.body.pop()

    def grow(self):
        x, y = self.body[0]
        if self.direction == 'up':
            y -= 1
        elif self.direction == 'down':
            y += 1
        elif self.direction == 'left':
            x -= 1
        elif self.direction == 'right':
            x += 1
        self.body.insert(0, (x, y))

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

    def draw(self):
        for x, y in self.body:
            pygame.draw.rect(screen, WHITE, (x * GRID_SIZE, y * GRID_SIZE, GRID_SIZE, GRID_SIZE))

# 定义食物类
class Food:
    def __init__(self):
        self.x = random.randint(0, GRID_WIDTH - 1)
        self.y = random.randint(0, GRID_HEIGHT - 1)

    def draw(self):
        pygame.draw.rect(screen, RED, (self.x * GRID_SIZE, self.y * GRID_SIZE, GRID_SIZE, GRID_SIZE))

# 创建蛇和食物对象
snake = Snake()
food = Food()

# 游戏循环
clock = pygame.time.Clock()
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
        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')

    # 移动蛇的位置
    snake.move()

    # 判断蛇是否吃到食物
    if snake.body[0] == (food.x, food.y):
        snake.grow()
        food = Food()

    # 判断蛇是否撞墙或撞到自己
    if snake.body[0][0] < 0 or snake.body[0][0] >= GRID_WIDTH or snake.body[0][1] < 0 or snake.body[0][1] >= GRID_HEIGHT:
        pygame.quit()
        quit()
    for i in range(1, len(snake.body)):
        if snake.body[0] == snake.body[i]:
            pygame.quit()
            quit()

    # 绘制游戏界面
    screen.fill(BLACK)
    snake.draw()
    food.draw()
    pygame.display.update()

    # 控制游戏速度
    clock.tick(10)

这个贪吃蛇游戏比较简单，只有基本的移动、吃食物、撞墙和撞到自己的判断。如果要增加游戏难度或者添加更多功能，可以在此基础上进行扩展。
