用pygame库做一个双人贪吃蛇的代码

好的，以下是用pygame库做一个双人贪吃蛇的代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 游戏区域的大小
screen_width = 600
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("双人贪吃蛇")

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

# 定义贪吃蛇的类
class Snake():
    def __init__(self, x, y, color):
        self.x = x
        self.y = y
        self.color = color
        self.direction = "RIGHT"
        self.length = 1
        self.body = []
        self.body.append([self.x, self.y])

    # 移动
    def move(self):
        if self.direction == "UP":
            self.y -= 10
        elif self.direction == "DOWN":
            self.y += 10
        elif self.direction == "LEFT":
            self.x -= 10
        elif self.direction == "RIGHT":
            self.x += 10

    # 检查是否吃到食物
    def eat_food(self, food):
        if self.x == food.x and self.y == food.y:
            self.length += 1
            self.body.append([self.x, self.y])
            food.generate()

    # 死亡检查
    def die(self):
        if self.x < 0 or self.x > screen_width or self.y < 0 or self.y > screen_height:
            return True
        for block in self.body[1:]:
            if self.x == block[0] and self.y == block[1]:
                return True
        return False

    # 更新身体
    def update_body(self):
        self.body.append([self.x, self.y])
        if len(self.body) > self.length:
            del self.body[0]

    # 绘制贪吃蛇
    def draw(self):
        for block in self.body:
            pygame.draw.rect(screen, self.color, [block[0], block[1], 10, 10])

# 定义食物的类
class Food():
    def __init__(self, color):
        self.color = color
        self.x = round(random.randrange(0, screen_width - 10) / 10.0) * 10.0
        self.y = round(random.randrange(0, screen_height - 10) / 10.0) * 10.0

    # 生成食物
    def generate(self):
        self.x = round(random.randrange(0, screen_width - 10) / 10.0) * 10.0
        self.y = round(random.randrange(0, screen_height - 10) / 10.0) * 10.0

    # 绘制食物
    def draw(self):
        pygame.draw.rect(screen, self.color, [self.x, self.y, 10, 10])

# 初始化贪吃蛇和食物
snake1 = Snake(100, 100, red)
snake2 = Snake(500, 500, green)
food = Food(black)

# 游戏循环
game_over = False
clock = pygame.time.Clock()

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:
                snake1.direction = "UP"
            elif event.key == pygame.K_DOWN:
                snake1.direction = "DOWN"
            elif event.key == pygame.K_LEFT:
                snake1.direction = "LEFT"
            elif event.key == pygame.K_RIGHT:
                snake1.direction = "RIGHT"
            elif event.key == pygame.K_w:
                snake2.direction = "UP"
            elif event.key == pygame.K_s:
                snake2.direction = "DOWN"
            elif event.key == pygame.K_a:
                snake2.direction = "LEFT"
            elif event.key == pygame.K_d:
                snake2.direction = "RIGHT"

    # 清除屏幕
    screen.fill(white)

    # 移动贪吃蛇
    snake1.move()
    snake2.move()

    # 检查是否吃到食物
    snake1.eat_food(food)
    snake2.eat_food(food)

    # 更新贪吃蛇的身体
    snake1.update_body()
    snake2.update_body()

    # 绘制贪吃蛇和食物
    snake1.draw()
    snake2.draw()
    food.draw()

    # 检查是否死亡
    if snake1.die() or snake2.die():
        game_over = True

    # 更新屏幕
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(20)

# 退出游戏
pygame.quit()
quit()

希望能够帮到你！
