python小游戏飞机大战

好的，下面是一个简单的Python飞机大战游戏的代码示例：

import pygame
import random

# 定义常量
SCREEN_WIDTH = 480
SCREEN_HEIGHT = 800
FRAME_RATE = 60
BULLET_SPEED = 10
ENEMY_SPEED = 5

# 初始化Pygame
pygame.init()

# 初始化游戏窗口
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("飞机大战")

# 加载游戏资源
background_image = pygame.image.load("background.png")
player_image = pygame.image.load("player.png")
bullet_image = pygame.image.load("bullet.png")
enemy_image = pygame.image.load("enemy.png")

# 定义游戏对象类
class GameObject:
    def __init__(self, x, y, image):
        self.x = x
        self.y = y
        self.image = image

    def draw(self, screen):
        screen.blit(self.image, (self.x, self.y))

# 定义玩家类
class Player(GameObject):
    def __init__(self):
        super().__init__(SCREEN_WIDTH // 2 - 25, SCREEN_HEIGHT - 100, player_image)
        self.bullets = []

    def move_left(self):
        self.x -= 5
        if self.x < 0:
            self.x = 0

    def move_right(self):
        self.x += 5
        if self.x > SCREEN_WIDTH - 50:
            self.x = SCREEN_WIDTH - 50

    def shoot(self):
        bullet = GameObject(self.x + 22, self.y - 30, bullet_image)
        self.bullets.append(bullet)

    def update(self):
        for bullet in self.bullets:
            bullet.y -= BULLET_SPEED
            if bullet.y < 0:
                self.bullets.remove(bullet)

    def draw(self, screen):
        super().draw(screen)
        for bullet in self.bullets:
            bullet.draw(screen)

# 定义敌人类
class Enemy(GameObject):
    def __init__(self):
        x = random.randint(0, SCREEN_WIDTH - 50)
        super().__init__(x, -50, enemy_image)

    def update(self):
        self.y += ENEMY_SPEED

# 初始化游戏对象
player = Player()
enemies = []

# 定义游戏循环
clock = pygame.time.Clock()
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                player.move_left()
            elif event.key == pygame.K_RIGHT:
                player.move_right()
            elif event.key == pygame.K_SPACE:
                player.shoot()

    # 更新游戏对象
    player.update()
    for enemy in enemies:
        enemy.update()

    # 添加敌人
    if random.randint(0, 60) == 0:
        enemy = Enemy()
        enemies.append(enemy)

    # 检测碰撞
    for enemy in enemies:
        if (enemy.x >= player.x and enemy.x <= player.x + 50 and
            enemy.y >= player.y and enemy.y <= player.y + 64):
            running = False
        for bullet in player.bullets:
            if (bullet.x >= enemy.x and bullet.x <= enemy.x + 50 and
                bullet.y >= enemy.y and bullet.y <= enemy.y + 30):
                player.bullets.remove(bullet)
                enemies.remove(enemy)

    # 绘制游戏界面
    screen.blit(background_image, (0, 0))
    player.draw(screen)
    for enemy in enemies:
        enemy.draw(screen)
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(FRAME_RATE)

# 退出游戏
pygame.quit()

在这个例子中，我们使用了Pygame库来创建游戏界面和处理游戏事件。我们定义了`GameObject`类来表示游戏对象，包括玩家、子弹和敌人。`Player`类继承自`GameObject`类，并添加了移动和射击的方法。`Enemy`类也继承自`GameObject`类，但是它只能向下移动。在游戏循环中，我们处理玩家的移动和射击操作，更新游戏对象的状态，检测碰撞并绘制游戏界面。当玩家与敌人相撞时，游戏结束。

这只是一个简单的示例，你可以根据自己的需求来设计更复杂的游戏逻辑和界面。
