不想看的直接看我贴代码吧.
代码层次:

1.pikachu类生成持续运动的pikachu

import cocos
import os


class Pikachu(cocos.sprite.Sprite):
    # 实现一个皮卡丘类来生成皮卡实例
    def __init__(self):
        super(Pikachu, self).__init__('pikachu.png')
        # 是否可以跳跃
        self.jumpable = False
        # 行进速度
        self.speed = 0
        # 锚点
        self.image_anchor = 0, 0
        # 皮卡丘的位置
        self.position = 80, 280
        self.schedule(self.update)

    def jump(self, h):
        # 声控跳跃
        if self.jumpable:
            self.y += 1
            self.speed -= max(min(h, 10), 7)
            self.jumpable = False

    def land(self, y):
        # 着陆后静止
        if self.y > y - 25:
            self.jumpable = True
            self.speed = 0
            self.y = y

    def update(self, dt):
        # 更新(重力下降)
        self.speed += 10 * dt
        self.y -= self.speed
        if self.y < -85:
            self.reset()

    def reset(self):
        self.parent.reset()
        self.jumpable = False
        self.speed = 0
        self.position = 80, 280

2.block类生成地图上随机出现的黑色柱子

import os
import cocos
import random


class Block(cocos.sprite.Sprite):
    # 生成地图上的随机块状物
    def __init__(self, position):
        super(Block, self).__init__('black.png')

        # 锚点
        self.image_anchor = 0, 0
        x, y = position
        if x == 0:
            self.scale_x = 4.5
            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
            self.position = x + 50 + random.random() * 100, 0

3.程序主逻辑入口函数

import os
import cocos
import struct
from cocos.sprite import Sprite
from pyaudio import PyAudio, paInt16
from classes.pikachu import Pikachu
from classes.block import Block


class VCGame(cocos.layer.ColorLayer):
    # 定义声音控制类Voice Control Class
    is_event_handler = True

    def __init__(self):
        super(VCGame, self).__init__(255, 255, 255, 255, 800, 600)
        # 初始化参数
        # frames_per_buffer
        self.numSamples = 1000
        # 声控条
        self.vbar = Sprite('black.png')
        self.vbar.position = 20, 450
        self.vbar.scale_y = 0.1
        self.vbar.image_anchor = 0, 0
        self.add(self.vbar)

        # 皮卡丘类
        self.pikachu = Pikachu()
        self.add(self.pikachu)

        # cocosnode精灵类
        self.floor = cocos.cocosnode.CocosNode()
        self.add(self.floor)
        position = 0, 100

        for i in range(120):
            b = Block(position)
            self.floor.add(b)
            position = b.x + b.width, b.height

        # 声音输入
        audio = PyAudio()
        SampleRate = int(audio.get_device_info_by_index(0)['defaultSampleRate'])
        self.stream = audio.open(format=paInt16,
                                 channels=1,
                                 rate=SampleRate,
                                 input=True,
                                 frames_per_buffer=self.numSamples)
        self.schedule(self.update)

        # 碰撞检测

    def collide(self):
        diffx = self.pikachu.x - self.floor.x
        for b in self.floor.get_children():
            if b.x <= diffx + self.pikachu.width * 0.8 and diffx + self.pikachu.width * 0.2 <= b.x + b.
                if self.pikachu.y < b.height:
                    self.pikachu.land(b.height)
                    break

        # 定义游戏规则

    def update(self, dt):
        # 获取每帧的音量
        audio_data = self.stream.read(self.numSamples)
        k = max(struct.unpack('1000h', audio_data))
        self.vbar.scale_x = k / 10000.0
        if k > 3000:
            self.floor.x -= min((k / 20.0), 150) * dt
        if k > 8000:
            self.pikachu.jump((k - 8000) / 1000.0)
        self.collide()

        # 重置

    def reset(self):
        self.floor.x = 0


if __name__ == '__main__':
    cocos.director.director.init(caption="Pikachu~~~")
    cocos.director.director.run(cocos.scene.Scene(VCGame()))
