怎么用Python实现小游戏飞机大战

本篇内容介绍了"怎么用Python实现小游戏飞机大战"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

一、环境安装

本文是写的游戏代码，基于Pygame的源码项目，这里是自己写的飞机大战的1.0版本，比较简陋。

准备：Python3、Pycharm、pygame模块以及自带的部分模块。

pip install -i https://pypi.douban.com/simple/  pygame

二、我方飞机

def main():    global is_hit    global nums    screen = pygame.display.set_mode((480, 852), 0, 32)    background = pygame.image.load("./feiji/background.png")    # 创建飞机    hero = HeroPlane(screen)    enermy_plane = EnermyPlane(screen)    while True:        global hero_nums        global enermy_nums        # 显示背景        screen.blit(background, (0, 0))        # 显示我方飞机        hero.display()        # 测试是否被子弹击中        hero.test(enermy_plane.bullets)        if hero.is_hit:            hero_nums += 1            if hero_nums == 10:                hero.image = pygame.image.load("./feiji/hero_blowup_n1.png")            elif hero_nums == 20:                hero.image = pygame.image.load("./feiji/hero_blowup_n2.png")            elif hero_nums == 30:                hero.image = pygame.image.load("./feiji/hero_blowup_n3.png")            elif hero_nums == 40:                hero.image = pygame.image.load("./feiji/hero_blowup_n4.png")            elif hero_nums > 50:                break

三、敌方飞机

 # 显示敌飞机        enermy_plane.display()        enermy_plane.test(hero.bullets)        if enermy_plane.is_hit:            enermy_nums += 1            if enermy_nums == 10:                enermy_plane.image = pygame.image.load("./feiji/enemy0_down1.png")            elif enermy_nums == 20:                enermy_plane.image = pygame.image.load("./feiji/enemy0_down2.png")            elif enermy_nums == 30:                enermy_plane.image = pygame.image.load("./feiji/enemy0_down3.png")            elif enermy_nums == 40:                enermy_plane.image = pygame.image.load("./feiji/enemy0_down4.png")            elif enermy_nums > 50:                enermy_plane = EnermyPlane(screen)                enermy_nums = 0        else:            enermy_plane.move()            enermy_plane.fire()         # 控制飞机左右        key_control(hero)        # 刷新屏幕        pygame.display.update()        # 程序休眠0.01秒        time.sleep(0.01)

四、控制键盘移动

def key_control(hero):    for event in pygame.event.get():        if event.type == QUIT:            print("exit")            exit()        elif event.type == KEYDOWN:            if event.key == K_a or event.key == K_LEFT:                hero.move_left()                print("left")            elif event.key == K_d or event.key == K_RIGHT:                hero.move_right()                print("right")            elif event.key == K_SPACE:                hero.fire()                print("space")

五、检测子弹碰撞

class BasePlane(object):    def __init__(self, screen, x, y, image):        self.x = x        self.y = y        self.screen = screen        self.image = pygame.image.load(image)        self.is_hit = False  # 此标志用来表示飞机是否被击中了        self.bullets = []     def test(self, bullets):        for bullet in bullets:            if self.x < bullet.x < self.x + self.image.get_width() and \                                    self.y < bullet.y < self.y + self.image.get_height():                self.is_hit = True                 #  检测子弹碰撞        for item in self.bullets:            for bullet in bullets:                if item.x < bullet.x < item.x + item.image.get_width() and \                                        item.y < bullet.y < item.y + item.image.get_height():                    item.is_hit = True                    bullet.is_hit = True
