Python吃豆豆游戏代码

以下是使用 Python 实现的吃豆豆游戏代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置窗口大小
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("吃豆豆游戏")

# 加载图片
player_image = pygame.image.load("player.png")
enemy_image = pygame.image.load("enemy.png")
food_image = pygame.image.load("food.png")

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

# 定义字体
font = pygame.font.Font(None, 36)

# 定义玩家、敌人和食物类
class Player:
    def __init__(self):
        self.image = player_image
        self.rect = self.image.get_rect()
        self.rect.x = screen_width / 2
        self.rect.y = screen_height / 2
        self.speed = 5
        self.score = 0

class Enemy:
    def __init__(self):
        self.image = enemy_image
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - self.rect.width)
        self.rect.y = random.randint(0, screen_height - self.rect.height)
        self.speed = 3

class Food:
    def __init__(self):
        self.image = food_image
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - self.rect.width)
        self.rect.y = random.randint(0, screen_height - self.rect.height)

# 创建玩家、敌人和食物对象
player = Player()
enemy = Enemy()
food = Food()

# 游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    
    # 移动玩家
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        player.rect.x -= player.speed
    if keys[pygame.K_RIGHT]:
        player.rect.x += player.speed
    if keys[pygame.K_UP]:
        player.rect.y -= player.speed
    if keys[pygame.K_DOWN]:
        player.rect.y += player.speed
    
    # 碰撞检测
    if player.rect.colliderect(enemy.rect):
        player.score -= 1
        enemy.rect.x = random.randint(0, screen_width - enemy.rect.width)
        enemy.rect.y = random.randint(0, screen_height - enemy.rect.height)
    if player.rect.colliderect(food.rect):
        player.score += 1
        food.rect.x = random.randint(0, screen_width - food.rect.width)
        food.rect.y = random.randint(0, screen_height - food.rect.height)
    
    # 移动敌人
    enemy_dx = random.randint(-enemy.speed, enemy.speed)
    enemy_dy = random.randint(-enemy.speed, enemy.speed)
    enemy.rect.x += enemy_dx
    enemy.rect.y += enemy_dy
    
    # 绘制界面
    screen.fill(WHITE)
    screen.blit(player.image, player.rect)
    screen.blit(enemy.image, enemy.rect)
    screen.blit(food.image, food.rect)
    score_text = font.render("分数：" + str(player.score), True, BLACK)
    screen.blit(score_text, (10, 10))
    pygame.display.update()

# 退出 Pygame
pygame.quit()

该代码使用 Pygame 库实现了一个基本的吃豆豆游戏，玩家可以使用方向键控制角色的移动，吃到食物可以得分，碰到敌人则扣分。游戏界面包含分数显示，可以通过调整图片和颜色等参数来个性化游戏。
