导语

宅在家里能干什么呢？突然想起了乒乓球?，要不约个好友一起去打打球也行啊，从尘封多年的纸箱子找到了羽毛球跟球拍，不知道着乒乓球去哪儿了? 算了，算了？？？不，说好的一起玩游戏呢，怎么能放弃！

肝了几个小时这款反弹球——仿制乒乓球小游戏终于出炉了，是单打、双打混合都可以！

重要的是：不用出门自己家里都能玩儿。这游戏我能玩一整天~简单好玩，让我们一起在家里动起来吧！

一、准备中

1)游戏规则

比平常的乒乓球?更简单，玩家只要接住球打回去即可，谁先获得10球就胜利（可修改）。

单人操作：方向键上下即可；双人模式：一个是方向键上下没错，还有一个就是WS上下。

2)素材准备

3)环境安装

本文用到的环境：Python3、Pycharm、Pygame模块部分自带。

pip install -i https://pypi.douban.com/simple/ +模块名

二、敲代码

1）配置文件

配置文件：背景颜色、界面大小、界面的一些背景音乐等等下面代码很简单都看的懂哈。

import os
 
'''屏幕长宽'''
WIDTH = 500
HEIGHT = 500
'''游戏素材路径'''
CURRPATH = os.getcwd()
RESOURCESDIRPATH = os.path.join(CURRPATH, 'resources')
AUDIOSDIRPATH = os.path.join(RESOURCESDIRPATH, 'audios')
FONTDIRPATH = os.path.join(RESOURCESDIRPATH, 'font')
IMAGESDIRPATH = os.path.join(RESOURCESDIRPATH, 'images')
BALLPICPATH = os.path.join(IMAGESDIRPATH, 'ball.png')
RACKETPICPATH = os.path.join(IMAGESDIRPATH, 'racket.png')
FONTPATH = os.path.join(FONTDIRPATH, 'font.TTF')
GOALSOUNDPATH = os.path.join(AUDIOSDIRPATH, 'goal.wav')
HITSOUNDPATH = os.path.join(AUDIOSDIRPATH, 'hit.wav')
BGMPATH = os.path.join(AUDIOSDIRPATH, 'bgm.mp3')
'''颜色'''
WHITE = (255, 255, 255)

2）设置球的反弹、移动规则

class Ball(pygame.sprite.Sprite):
    def __init__(self, imgpath, cfg, **kwargs):
        pygame.sprite.Sprite.__init__(self)
        self.cfg = cfg
        self.image = loadImage(imgpath)
        self.rect = self.image.get_rect()
        self.reset()
    '''移动'''
    def move(self, ball, racket_left, racket_right, hit_sound, goal_sound):
        self.rect.left = self.rect.left + self.speed * self.direction_x
        self.rect.top = min(max(self.rect.top + self.speed * self.direction_y, 0), self.cfg.HEIGHT - self.rect.height)
        # 撞到球拍
        if pygame.sprite.collide_rect(ball, racket_left) or pygame.sprite.collide_rect(ball, racket_right):
            self.direction_x, self.direction_y = -self.direction_x, random.choice([1, -1])
            self.speed += 1
            scores = [0, 0]
            hit_sound.play()
        # 撞到上侧的墙
        elif self.rect.top == 0:
            self.direction_y = 1
            self.speed += 1
            scores = [0, 0]
        # 撞到下侧的墙
        elif self.rect.top == self.cfg.HEIGHT - self.rect.height:
            self.direction_y = -1
            self.speed += 1
            scores = [0, 0]
        # 撞到左边的墙
        elif self.rect.left < 0:
            self.reset()
            racket_left.reset()
            racket_right.reset()
            scores = [0, 1]
            goal_sound.play()
        # 撞到右边的墙
        elif self.rect.right > self.cfg.WIDTH:
            self.reset()
            racket_left.reset()
            racket_right.reset()
            scores = [1, 0]
            goal_sound.play()
        # 普通情况
        else:
            scores = [0, 0]
        return scores
    '''初始化'''
    def reset(self):
        self.rect.centerx = self.cfg.WIDTH // 2
        self.rect.centery = random.randrange(self.rect.height // 2, self.cfg.HEIGHT - self.rect.height // 2)
        self.direction_x = random.choice([1, -1])
        self.direction_y = random.choice([1, -1])
        self.speed = 1
    '''绑定到屏幕上'''
    def draw(self, screen):
        screen.blit(self.image, self.rect)

3）设置球拍电脑的移动等

class Racket(pygame.sprite.Sprite):
    def __init__(self, imgpath, type_, cfg, **kwargs):
        pygame.sprite.Sprite.__init__(self)
        self.cfg = cfg
        self.type_ = type_
        self.image = loadImage(imgpath, False)
        self.rect = self.image.get_rect()
        self.reset()
    '''移动'''
    def move(self, direction):
        if direction == 'UP':
            self.rect.top = max(0, self.rect.top - self.speed)
        elif direction == 'DOWN':
            self.rect.bottom = min(self.cfg.HEIGHT, self.rect.bottom + self.speed)
        else:
            raise ValueError('[direction] in Racket.move is %s, expect %s or %s...' % (direction, 'UP', 'DOWN'))
    '''电脑自动移动'''
    def automove(self, ball):
        if ball.rect.centery - 25 > self.rect.centery:
            self.move('DOWN')
        if ball.rect.centery + 25 < self.rect.centery:
            self.move('UP')
    '''初始化'''
    def reset(self):
        # 左/右边的拍
        self.rect.centerx = self.cfg.WIDTH - self.rect.width // 2 if self.type_ == 'RIGHT' else self.rect.width // 2
        self.rect.centery = self.cfg.HEIGHT // 2
        # 速度
        self.speed = 5
    '''绑定到屏幕上'''
    def draw(self, screen):
        screen.blit(self.image, self.rect)

4）设置游戏开始界面

?开始界面分单、双人游戏。

def startInterface(screen):
    clock = pygame.time.Clock()
    while True:
        screen.fill((41, 36, 33))
        button_1 = Button(screen, (150, 175), '1 Player')
        button_2 = Button(screen, (150, 275), '2 Player')
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()
            if event.type == pygame.MOUSEBUTTONDOWN:
                if button_1.collidepoint(pygame.mouse.get_pos()):
                    return 1
                elif button_2.collidepoint(pygame.mouse.get_pos()):
                    return 2
        clock.tick(10)
        pygame.display.update()

5）定义游戏结束页面

谁先胜利达到10个球，结束界面设置。

def endInterface(screen, score_left, score_right):
    clock = pygame.time.Clock()
    font1 = pygame.font.Font(cfg.FONTPATH, 30)
    font2 = pygame.font.Font(cfg.FONTPATH, 20)
    msg = 'Player on left won!' if score_left > score_right else 'Player on right won!'
    texts = [font1.render(msg, True, cfg.WHITE),
            font2.render('Press ESCAPE to quit.', True, cfg.WHITE),
            font2.render('Press ENTER to continue or play again.', True, cfg.WHITE)]
    positions = [[120, 200], [155, 270], [80, 300]]
    while True:
        screen.fill((41, 36, 33))
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RETURN:
                    return
                elif event.key == pygame.K_ESCAPE:
                    sys.exit()
                    pygame.quit()
        for text, pos in zip(texts, positions):
            screen.blit(text, pos)
        clock.tick(10)
        pygame.display.update()

6）运行游戏Demo

def runDemo(screen):
    # 加载游戏素材
    hit_sound = pygame.mixer.Sound(cfg.HITSOUNDPATH)
    goal_sound = pygame.mixer.Sound(cfg.GOALSOUNDPATH)
    pygame.mixer.music.load(cfg.BGMPATH)
    pygame.mixer.music.play(-1, 0.0)
    font = pygame.font.Font(cfg.FONTPATH, 50)
    # 开始界面
    game_mode = startInterface(screen)
    # 游戏主循环
    # --左边球拍(ws控制, 仅双人模式时可控制)
    score_left = 0
    racket_left = Racket(cfg.RACKETPICPATH, 'LEFT', cfg)
    # --右边球拍(↑↓控制)
    score_right = 0
    racket_right = Racket(cfg.RACKETPICPATH, 'RIGHT', cfg)
    # --球
    ball = Ball(cfg.BALLPICPATH, cfg)
    clock = pygame.time.Clock()
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit(-1)
        screen.fill((41, 36, 33))
        # 玩家操作
        pressed_keys = pygame.key.get_pressed()
        if pressed_keys[pygame.K_UP]:
            racket_right.move('UP')
        elif pressed_keys[pygame.K_DOWN]:
            racket_right.move('DOWN')
        if game_mode == 2:
            if pressed_keys[pygame.K_w]:
                racket_left.move('UP')
            elif pressed_keys[pygame.K_s]:
                racket_left.move('DOWN')
        else:
            racket_left.automove(ball)
        # 球运动
        scores = ball.move(ball, racket_left, racket_right, hit_sound, goal_sound)
        score_left += scores[0]
        score_right += scores[1]
        # 显示
        # --分隔线
        pygame.draw.rect(screen, cfg.WHITE, (247, 0, 6, 500))
        # --球
        ball.draw(screen)
        # --拍
        racket_left.draw(screen)
        racket_right.draw(screen)
        # --得分
        screen.blit(font.render(str(score_left), False, cfg.WHITE), (150, 10))
        screen.blit(font.render(str(score_right), False, cfg.WHITE), (300, 10))
        if score_left == 11 or score_right == 11:
            return score_left, score_right
        clock.tick(100)
        pygame.display.update()

7）主函数、标题名称等

'''主函数'''
def main():
    # 初始化
    pygame.init()
    pygame.mixer.init()
    screen = pygame.display.set_mode((cfg.WIDTH, cfg.HEIGHT))
    pygame.display.set_caption('反弹球小游戏')
    # 开始游戏
    while True:
        score_left, score_right = runDemo(screen)
        endInterface(screen, score_left, score_right)
