pygame小游戏代码

下面是一个简单的 Pygame 小游戏的代码示例，这个游戏是一个飞机射击游戏：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 定义常量
WINDOW_WIDTH = 600
WINDOW_HEIGHT = 800
ENEMY_SIZE = 50
ENEMY_SPEED = 5
BULLET_SPEED = 10

# 创建窗口
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("飞机射击游戏")

# 加载图片
player_img = pygame.image.load("player.png").convert_alpha()
enemy_img = pygame.image.load("enemy.png").convert_alpha()
bullet_img = pygame.image.load("bullet.png").convert_alpha()

# 定义游戏对象
class Player:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.img = player_img
        self.width = self.img.get_width()
        self.height = self.img.get_height()
        self.speed = 10

    def move_left(self):
        if self.x > 0:
            self.x -= self.speed

    def move_right(self):
        if self.x < WINDOW_WIDTH - self.width:
            self.x += self.speed

    def shoot(self):
        return Bullet(self.x + self.width / 2 - BULLET_SPEED / 2, self.y - BULLET_SPEED)

class Enemy:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.img = enemy_img
        self.width = self.img.get_width()
        self.height = self.img.get_height()
        self.speed = ENEMY_SPEED

    def move(self):
        self.y += self.speed

class Bullet:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.img = bullet_img
        self.width = self.img.get_width()
        self.height = self.img.get_height()
        self.speed = BULLET_SPEED

    def move(self):
        self.y -= self.speed

# 定义游戏逻辑
def run_game():
    # 创建玩家对象
    player = Player(WINDOW_WIDTH / 2 - player_img.get_width() / 2, WINDOW_HEIGHT - player_img.get_height())

    # 创建敌人列表
    enemies = []

    # 创建子弹列表
    bullets = []

    # 游戏主循环
    while True:
        # 处理事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                return

        # 移动玩家对象
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            player.move_left()
        if keys[pygame.K_RIGHT]:
            player.move_right()

        # 射击子弹
        if keys[pygame.K_SPACE]:
            bullets.append(player.shoot())

        # 移动敌人对象
        if len(enemies) < 10:
            enemies.append(Enemy(random.randint(0, WINDOW_WIDTH - ENEMY_SIZE), -ENEMY_SIZE))
        for enemy in enemies:
            enemy.move()

        # 移动子弹对象
        for bullet in bullets:
            bullet.move()

        # 检测碰撞
        for enemy in enemies:
            for bullet in bullets:
                if (bullet.x > enemy.x and bullet.x < enemy.x + enemy.width and bullet.y > enemy.y and bullet.y < enemy.y + enemy.height):
                    enemies.remove(enemy)
                    bullets.remove(bullet)

        # 渲染游戏对象
        window.fill((255, 255, 255))
        for enemy in enemies:
            window.blit(enemy.img, (enemy.x, enemy.y))
        for bullet in bullets:
            window.blit(bullet.img, (bullet.x, bullet.y))
        window.blit(player.img, (player.x, player.y))
        pygame.display.update()

# 启动游戏
run_game()

请注意，这个代码仅用于演示 Pygame 的使用方法，实际游戏中可能需要更多的功能和优化。
