不要停，八分音符酱

最近微博特别火的一个小游戏，看视频都看的笑尿。

然后在一个开源社区看到了有个大神仅仅用了100行代码就实现了这款小游戏，然后我就拿来学习学习。

python代码

1，game.py

#coding: utf8import cocosfrom cocos.sprite import Spritefrom pyaudio import PyAudio, paInt16import structfrom ppx import PPXfrom block import Blockclass VoiceGame(cocos.layer.ColorLayer):    is_event_handler = True    def __init__(self):        super(VoiceGame, self).__init__(255, 255, 255, 255, 800, 600)        self.logo = cocos.sprite.Sprite('123.jpg')        self.logo.position = 550, 400        self.add(self.logo, 99999)        # init voice        self.NUM_SAMPLES = 1000  # pyAudio内部缓存的块的大小        self.LEVEL = 1500  # 声音保存的阈值        self.voicebar = Sprite('black.png', color=(0, 0, 255))        self.voicebar.position = 20, 450        self.voicebar.scale_y = 0.1        self.voicebar.image_anchor = 0, 0        self.add(self.voicebar)        self.ppx = PPX()        self.add(self.ppx)        self.floor = cocos.cocosnode.CocosNode()        self.add(self.floor)        pos = 0, 100        for i in range(100):            b = Block(pos)            self.floor.add(b)            pos = b.x + b.width, b.height        # 开启声音输入        pa = PyAudio()        SAMPLING_RATE = int(pa.get_device_info_by_index(0)['defaultSampleRate'])        self.stream = pa.open(format=paInt16, channels=1, rate=SAMPLING_RATE, input=True, frames_per_buffer=self.NUM_SAMPLES)        self.schedule(self.update)    def on_mouse_press(self, x, y, buttons, modifiers):        pass    def collide(self):        px = self.ppx.x - self.floor.x        for b in self.floor.get_children():            if b.x <= px + self.ppx.width * 0.8 and px + self.ppx.width * 0.2 <= b.x + b.width:                if self.ppx.y < b.height:                    self.ppx.land(b.height)                    break    def update(self, dt):        # 读入NUM_SAMPLES个取样        string_audio_data = self.stream.read(self.NUM_SAMPLES)        k = max(struct.unpack('1000h', string_audio_data))        # print k        self.voicebar.scale_x = k / 10000.0        if k > 3000:            self.floor.x -= min((k / 20.0), 150) * dt        if k > 8000:            self.ppx.jump((k - 8000) / 1000.0)        self.collide()    def reset(self):        self.floor.x = 0cocos.director.director.init(caption="Let's Go! PiPiXia!")cocos.director.director.run(cocos.scene.Scene(VoiceGame()))

2,ppx.py

# -*- coding: utf-8 -*-import mathimport randomimport cocosclass PPX(cocos.sprite.Sprite):    def __init__(self):        super(PPX, self).__init__('ppx.png')        self.can_jump = False        self.speed = 0        self.image_anchor = 0, 0        self.position = 100, 300        self.schedule(self.update)    def jump(self, h):        if self.can_jump:            self.y += 1            self.speed -= max(min(h, 10), 7)            self.can_jump = False    def land(self, y):        if self.y > y - 30:            self.can_jump = True            self.speed = 0            self.y = y    def update(self, dt):        self.speed += 10 * dt        self.y -= self.speed        if self.y < -80:            self.reset()    def reset(self):        self.parent.reset()        self.can_jump = False        self.speed = 0        self.position = 100, 300

3,black.py

# -*- coding: utf-8 -*-import mathimport randomimport cocosclass Block(cocos.sprite.Sprite):    def __init__(self, pos):        super(Block, self).__init__('black.png')        self.image_anchor = 0, 0        x, y = pos        if x == 0:            self.scale_x = 5            self.scale_y = 1        else:            self.scale_x = 0.5 + random.random() * 1.5            self.scale_y = min(max(y - 50 + random.random() * 100, 50), 300) / 100.0            self.position = x + 50 + random.random() * 100, 0

其实实现思路也很简单，随机生成的障碍物（black），无线循环。black实际上是在向左边移动。

运动的可以换成自己的图片，哈哈哈，尖叫吧。
