用python写一个飞机大战小游戏

### 回答1：
好的，以下是一个简单的Python飞机大战小游戏的代码示例：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))

# 加载背景图片
background = pygame.image.load('images/background.png')

# 加载飞机图片
plane_img = pygame.image.load('images/plane.png')
plane_rect = plane_img.get_rect()
plane_width = plane_rect.width
plane_height = plane_rect.height

# 加载子弹图片
bullet_img = pygame.image.load('images/bullet.png')
bullet_rect = bullet_img.get_rect()
bullet_width = bullet_rect.width
bullet_height = bullet_rect.height

# 加载敌机图片
enemy_img = pygame.image.load('images/enemy.png')
enemy_rect = enemy_img.get_rect()
enemy_width = enemy_rect.width
enemy_height = enemy_rect.height

# 设置字体
font = pygame.font.Font(None, 36)

# 设置游戏帧率
clock = pygame.time.Clock()
fps = 60

# 定义飞机类
class Plane(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = plane_img
        self.rect = self.image.get_rect()
        self.rect.centerx = screen_width // 2
        self.rect.bottom = screen_height - 10
        self.speed = 5
        self.bullets = pygame.sprite.Group()

    def update(self):
        # 处理键盘事件
        key_pressed = pygame.key.get_pressed()
        if key_pressed[pygame.K_LEFT]:
            self.rect.x -= self.speed
        elif key_pressed[pygame.K_RIGHT]:
            self.rect.x += self.speed
        if key_pressed[pygame.K_SPACE]:
            self.fire()

        # 防止飞机飞出屏幕
        if self.rect.left < 0:
            self.rect.left = 0
        elif self.rect.right > screen_width:
            self.rect.right = screen_width

    def fire(self):
        bullet = Bullet()
        bullet.rect.centerx = self.rect.centerx
        bullet.rect.bottom = self.rect.top
        self.bullets.add(bullet)

# 定义子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = bullet_img
        self.rect = self.image.get_rect()
        self.speed = 10

    def update(self):
        self.rect.y -= self.speed
        if self.rect.bottom < 0:
            self.kill()

# 定义敌机类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = enemy_img
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - enemy_width)
        self.rect.y = random.randint(-enemy_height, -10)
        self.speed = random.randint(1, 5)

    def update(self):
        self.rect.y += self.speed
        if self.rect.top > screen_height:
            self.kill()

# 创建精灵组
all_sprites = pygame.sprite.Group()

# 创建飞机精灵
plane = Plane()
all_sprites.add(plane)

# 创建敌机精灵组
enemies = pygame.sprite.Group()

# 设置初始得分
score = 0

# 游戏主循环
running = True
while running:

飞机大战是一个非常经典的小游戏，在Python中实现它并不复杂。以下是一个简单的实现代码示例：

import pygame
import random

pygame.init()

# 定义窗口和背景
WIDTH = 800
HEIGHT = 600
window = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("飞机大战")
background = pygame.image.load("background.jpg")

# 定义玩家飞机
player_image = pygame.image.load("player.png")
player_x = WIDTH // 2 - player_image.get_width() // 2
player_y = HEIGHT - player_image.get_height() - 10
player_speed = 5

def player(x, y):
window.blit(player_image, (x, y))

# 定义敌机
enemy_image = pygame.image.load("enemy.png")
enemy_x = random.randint(0, WIDTH - enemy_image.get_width())
enemy_y = 0
enemy_speed = 3

def enemy(x, y):
window.blit(enemy_image, (x, y))

# 判断碰撞
def is_collision(enemy_x, enemy_y, player_x, player_y):
distance = ((enemy_x - player_x) ** 2 + (enemy_y - player_y) ** 2) ** 0.5
if distance < 27:
return True
else:
return False

# 游戏循环
running = True
while running:
window.fill((0, 0, 0))
window.blit(background, (0, 0))

for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False

keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
player_x -= player_speed
if keys[pygame.K_RIGHT]:
player_x += player_speed

player(player_x, player_y)

enemy(enemy_x, enemy_y)
enemy_y += enemy_speed

if enemy_y > HEIGHT:
enemy_x = random.randint(0, WIDTH - enemy_image.get_width())
enemy_y = 0

if is_collision(enemy_x, enemy_y, player_x, player_y):
running = False

pygame.display.update()

pygame.quit()

在此示例中，我们使用了pygame库来创建游戏窗口、加载图像和处理用户输入。玩家使用左右箭头键来控制飞机的移动，并且敌机会从顶部不断向下移动。如果玩家的飞机与敌机发生碰撞，则游戏结束。

请注意，该示例可能需要根据你计算机上的实际文件路径和图像来进行一些修改。你可以使用任何你喜欢的图片作为背景、玩家飞机和敌机。希望这个简单的示例能对你有所帮助！
