Python实现飞机大战游戏

为了熟悉Python基础语法，学习了一个经典的案例：飞机大战，最后实现效果如下：

实现步骤：

①下载64位对应python版本的pygame：pygame-1.9.6-cp38-cp38-win_amd64.whl

② 更新pip：python -m pip install --upgrade pip

③ 安装pygame：pip install pygame-1.9.6-cp38-cp38-win_amd64.whl

④ 实现代码如下：

import sys  # 导入系统模块
import random  # 随机数模块
import pygame  # 导入pygame模块
import pygame.locals  # 导入pygame本地策略

ICO_PATH = "images/app.ico"  # APP_ICO
APP_NAME = "飞机大战V1.0"  # APP_NAME
Enemy_IMGS = ("images/enemy1.png", "images/enemy2.png")  # ENEMY_IMGS


# TODO 定义一个公共类
class Model:
    window = None  # 主窗体window对象

    # 初始化函数
    def __init__(self, img_path, x, y):
        self.img = pygame.image.load(img_path)
        self.x = x
        self.y = y

    # 将图片填充到背景中
    def display(self):
        Model.window.blit(self.img, (self.x, self.y))


# TODO 背景
class Background(Model):
    # 背景移动
    def move(self):
        if self.y <= Game.WINDOW_HEIGHT:
            self.y += 1
        else:
            self.y = 0

    # 背景图片展示
    def display(self):
        Model.window.blit(self.img, (self.x, self.y))  # 填充背景
        Model.window.blit(self.img, (self.x, self.y - Game.WINDOW_HEIGHT))  # 填充辅助背景


# TODO 玩家类
class PlayerPlane(Model):
    def __init__(self, img_path, x, y):
        super().__init__(img_path, x, y)
        # 子弹
        self.bullets = []

    def display(self, enemys):
        super().display()
        remove_bullets = []
        for bullet in self.bullets:

            bullet.move()
            bullet.display()
            # 如果子弹小于消失于屏幕，删除子弹
            if bullet.y < -11:
                remove_bullets.append(bullet)
            # 子弹的矩阵
            bullet_rect = pygame.locals.Rect(bullet.x, bullet.y, 5, 11)
            # TODO 进行碰撞检测
            for enemy in enemys:
                # 敌机的矩阵
                enemy_rect = pygame.locals.Rect(enemy.x, enemy.y, 57, 43)
                # 如果碰撞
                if pygame.Rect.colliderect(bullet_rect, enemy_rect):
                    # 随机修改敌机的位置模拟敌机销毁并生成新敌机并删除子弹
                    enemy.img = pygame.image.load(Enemy_IMGS[random.randint(0, 1)])
                    enemy.x = random.randint(0, Game.WINDOW_WIDTH - 57)

    def move(self):
        if self.y > Game.WINDOW_HEIGHT:

        else:
            self.y += 1

            self.background.display()  # 将图片塞入到窗体中

            self.player.display(self.enemyPlanes)
