用PYTHON写一个吃豆人

很高兴回答你的问题！下面是一个简单的吃豆人游戏，使用 Python 编写。

import pygame
import random

# 游戏初始化
pygame.init()
width, height = 640, 480
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("吃豆人游戏")

# 颜色定义
black = (0, 0, 0)
white = (255, 255, 255)
red = (255, 0, 0)
blue = (0, 0, 255)
yellow = (255, 255, 0)

# 游戏设置
block_size = 20
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 25)

# 游戏数据
score = 0

def draw_score(score):
    score_text = font.render("Score: {}".format(score), True, white)
    screen.blit(score_text, [0, 0])

def draw_block(color, position):
    block = pygame.Rect(position[0], position[1], block_size, block_size)
    pygame.draw.rect(screen, color, block)

def game_over():
    message("Game Over", red)
    pygame.display.update()
    pygame.time.delay(2000)
    pygame.quit()
    quit()

def message(text, color):
    text = font.render(text, True, color)
    screen.blit(text, [width / 2 - text.get_rect().width / 2, height / 2 - text.get_rect().height / 2])

# 主程序循环
def game_loop():
    global score
    game_exit = False

    # 初始化吃豆人和豆子
    player_position = [width / 2, height / 2]
    player_movement = [0, 0]
    enemy_position = [random.randint(0, width // block_size) * block_size, random.randint(0, height // block_size) * block_size]
    enemy_movement = [0, 0]
    foods = []
    for i in range(10):
        food_position = [random.randint(0, width // block_size) * block_size, random.randint(0, height // block_size) * block_size]
        foods.append(food_position)

    # 游戏循环
    while not game_exit:

                    player_movement[1] = 0
                elif event.key == pygame.K_RIGHT:
                    player_movement[0] = block_size
                    player_movement[1] = 0
                elif event.key == pygame.K_UP:

        # 更新吃豆人和豆子位置
        player_position[0] += player_movement[0]
        player_position[1] += player_movement[1]
        enemy_position[0] += enemy_movement[0]
        enemy_position[1] += enemy_movement[1]

        # 检查是否撞墙
        if player_position[0] < 0 or player_position[0] > width - block_size or player_position[1] < 0 or player_position[1] > height - block_size:
            game_over()

        # 检查是否碰到敌人
        if player_position == enemy_position:
            game_over()

        # 检查是否吃到豆子
        for food_position in foods:
            if player_position == food_position:
                score += 10
                foods.remove(food_position)

        # 生成新的豆子
        while len(foods) < 10:
            food_position = [random.randint(0, width // block_size) * block_size, random.randint(0, height // block_size) * block_size]
            if food_position not in foods and food_position != player_position and food_position != enemy_position:
                foods.append(food_position)

        # 绘制游戏界面
        screen.fill(black)
        draw_block(yellow, player_position)
        draw_block(blue, enemy_position)
        for food_position in foods:
            draw_block(red, food_position)
        draw_score(score)
        pygame.display.update()

        # 控制游戏速度
        clock.tick(20)

    pygame.quit()
    quit()

game_loop()

以上是一个简单的吃豆人游戏实现，希望能够帮到你！
