请给我编一个类似的游戏

好的，我可以为您提供一个简单的类似游戏的代码示例。以下是一个基于Python语言和Pygame库的羊过河小游戏代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口大小和标题
WINDOW_WIDTH = 480
WINDOW_HEIGHT = 640
GAME_WINDOW = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("羊过河")

# 设置游戏颜色
WHITE_COLOR = (255, 255, 255)
BLACK_COLOR = (0, 0, 0)

# 加载游戏图片
BACKGROUND_IMG = pygame.image.load("background.jpg")
SHEEP_IMG = pygame.image.load("sheep.png")
ROCK_IMG = pygame.image.load("rock.png")
BOAT_IMG = pygame.image.load("boat.png")

# 设置游戏元素的大小和位置
SHEEP_SIZE = 50
SHEEP_X = WINDOW_WIDTH // 2 - SHEEP_SIZE // 2
SHEEP_Y = WINDOW_HEIGHT - SHEEP_SIZE
ROCK_SIZE = 50
ROCK_X = [random.randint(0, WINDOW_WIDTH - ROCK_SIZE) for i in range(3)]
ROCK_Y = [random.randint(0, WINDOW_HEIGHT - SHEEP_SIZE - ROCK_SIZE) for i in range(3)]
BOAT_SIZE = 80
BOAT_X = WINDOW_WIDTH // 2 - BOAT_SIZE // 2
BOAT_Y = SHEEP_Y - BOAT_SIZE
BOAT_SPEED = 5

# 设置游戏状态和计数器
GAME_OVER = False
SCORE = 0
FPS = 60
CLOCK = pygame.time.Clock()

# 游戏主循环
while not GAME_OVER:

    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            GAME_OVER = True

    # 移动船
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and BOAT_X > 0:
        BOAT_X -= BOAT_SPEED
    elif keys[pygame.K_RIGHT] and BOAT_X < WINDOW_WIDTH - BOAT_SIZE:
        BOAT_X += BOAT_SPEED

    # 移动石头
    for i in range(len(ROCK_X)):
        ROCK_Y[i] += 2
        if ROCK_Y[i] > WINDOW_HEIGHT:
            ROCK_Y[i] = -ROCK_SIZE
            ROCK_X[i] = random.randint(0, WINDOW_WIDTH - ROCK_SIZE)

        # 碰撞检测
        if ROCK_Y[i] + ROCK_SIZE > SHEEP_Y and \
                ROCK_Y[i] < SHEEP_Y + SHEEP_SIZE and \
                ROCK_X[i] + ROCK_SIZE > SHEEP_X and \
                ROCK_X[i] < SHEEP_X + SHEEP_SIZE:
            GAME_OVER = True

        if ROCK_Y[i] + ROCK_SIZE > BOAT_Y and \
                ROCK_Y[i] < BOAT_Y + BOAT_SIZE and \
                ROCK_X[i] + ROCK_SIZE > BOAT_X and \
                ROCK_X[i] < BOAT_X + BOAT_SIZE:
            SCORE += 1
            ROCK_Y[i] = -ROCK_SIZE
            ROCK_X[i] = random.randint(0, WINDOW_WIDTH - ROCK_SIZE)

    # 绘制游戏元素
    GAME_WINDOW.blit(BACKGROUND_IMG, (0, 0))
    GAME_WINDOW.blit(SHEEP_IMG, (SHEEP_X, SHEEP_Y))
    GAME_WINDOW.blit(BOAT_IMG, (BOAT_X, BOAT_Y))
    for i in range(len(ROCK_X)):
        GAME_WINDOW.blit(ROCK_IMG, (ROCK_X[i], ROCK_Y[i]))

    # 绘制得分
    font = pygame.font.SysFont(None, 40)
    score_text = font.render("Score: " + str(SCORE), True, BLACK_COLOR)
    GAME_WINDOW.blit(score_text, (10, 10))

    # 更新游戏窗口
    pygame.display.update()

    # 控制游戏运行帧率
    CLOCK.tick(FPS)

# 退出 Pygame
pygame.quit()

注意：这只是一个简单的示例，实际上制作一个完整的游戏需要更多的代码和资源。如果您对游戏开发感兴趣，建议学习相关的游戏开发知识，了解更多关于游戏制作的内容。
