编写程序简易大鱼吃小鱼(Python

好的，以下是一个简易的大鱼吃小鱼游戏的Python程序：

import random

# 定义游戏区域大小
WIDTH = 800
HEIGHT = 600

# 定义颜色
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)

# 初始化pygame
pygame.init()

# 创建游戏窗口
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("大鱼吃小鱼")

# 加载图片
fish_image = pygame.image.load("fish.png")
fish_rect = fish_image.get_rect()

small_fish_image = pygame.image.load("small_fish.png")
small_fish_rect = small_fish_image.get_rect()

# 初始化小鱼位置和速度
small_fish_x = random.randint(0, WIDTH - small_fish_rect.width)
small_fish_y = random.randint(0, HEIGHT - small_fish_rect.height)
small_fish_speed = 5

# 初始化大鱼位置和速度
fish_x = WIDTH / 2
fish_y = HEIGHT / 2
fish_speed = 10

# 游戏循环
while True:

    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    # 获取按键状态
    keys = pygame.key.get_pressed()

    # 处理按键事件
    if keys[pygame.K_LEFT]:
        fish_x -= fish_speed
    if keys[pygame.K_RIGHT]:
        fish_x += fish_speed
    if keys[pygame.K_UP]:
        fish_y -= fish_speed
    if keys[pygame.K_DOWN]:
        fish_y += fish_speed

    # 处理小鱼移动
    small_fish_x += small_fish_speed
    if small_fish_x > WIDTH:
        small_fish_x = 0 - small_fish_rect.width
        small_fish_y = random.randint(0, HEIGHT - small_fish_rect.height)

    # 判断是否吃到小鱼
    if fish_rect.colliderect(small_fish_rect):
        small_fish_x = 0 - small_fish_rect.width
        small_fish_y = random.randint(0, HEIGHT - small_fish_rect.height)

    # 绘制游戏界面
    screen.fill(WHITE)
    screen.blit(fish_image, (fish_x, fish_y))
    screen.blit(small_fish_image, (small_fish_x, small_fish_y))
    pygame.display.update()

在运行程序之前，你需要下载两张图片（分别为大鱼和小鱼的图片），并将它们保存在程序所在的目录下，然后在代码中将它们的路径替换成你自己的路径。

运行程序后，你可以使用方向键来控制大鱼的移动，当大鱼碰到小鱼时，小鱼会被吃掉并重新生成一个新的小鱼。
