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: utf8 import cocos from cocos.sprite import Sprite from pyaudio import PyAudio, paInt16 import struct from ppx import PPX from block import Block class 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 = 0 cocos.director.director.init(caption="Let's Go! PiPiXia!") cocos.director.director.run(cocos.scene.Scene(VoiceGame())) 

2,ppx.py

讯享网# -*- coding: utf-8 -*- import math import random import cocos class 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 math import random import cocos class 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。
