 # 模拟球弹跳

-* 定义两个变量，一个speed，一个accelerate。
-* 设置 ball 与 ground 为BoxCollider。检测下落碰撞，设置speed为defaultSpeed
-* 在update中设置代码
-~~~
-   /**
-     * 球运动计算
-     */
-    drop() {
-        this.node.y += this.speed;
-        this.speed += this.accelerate;
-    }
-~~~

+# BigNumber64Demo
+> 介绍如何在 javascript 处理64位大数。
+### 方案1
+[long.js](https://github.com/dcodeIO/long.js) 库
+##### 介绍 
+A Long class for representing a 64 bit two's-complement integer value derived from the Closure Library for stand-alone use and extended with unsigned support.
+
+##### 简单使用
+~~~
+var Long = require("long");
+
+var longVal = new Long(0xFFFFFFFF, 0x7FFFFFFF);
+
+console.log(longVal.toString());
+~~~
+
+##### 优势
+* 可以把服务器发过来的高位、底位数据合成一个大数。显示，+、-、*、/、。
+
+### 方案2
+[bignumber.js](https://github.com/alexbardas/bignumber.js) 库
+##### 介绍
+BigNumber.js is a light javascript library for node.js and the browser. It supports arithmetic operations on Big Integers.
+
+It is build with performance in mind, uses the fastest algorithms and supports all basic arithmetic operations (+, -, *, /, %, ^, abs). Works with both positive and negative big integers.
+
+##### 简单介绍
+~~~
+var BigNumber = require('big-number');
+
+BigNumber(5).plus(97).minus(53).plus(434).multiply(5435423).add(321453).multiply(21).div(2).pow(2);
+// 760056543044267246001
+~~~
+
+##### 优势
+* 支持add/plus, minus/subtract, multiply/mult, divide/div, power/pow, mod, equals, lt, lte, gt, gte, isZero, abs

+# 热更新工具说明
+* GameConfig.json 游戏版本、打包配置
+* BuildBeforeSetting.js 构建前准备工作 如：设置版本号，设置为正式服，等等~
+* FileUtil.js 文件操作工具类
+* CopyHotFiles.js 把需要热更文件复制到新文件夹
+* VersionGenerator.js 生成文件信息，作为版本资源对比。十分重要
+* ModifyFileTime.py 修改文件的生成时间
+* ZipFile.py 把文件压缩
+
+### 准备
+* 操作系统：window
+* 安装Node https://nodejs.org/zh-cn/
+* 安装Python 2.7 or 3.7
+* 以下操作都是基于android 打包 且模式为[link](https://docs.cocos.com/creator/manual/zh/publish/publish-native.html?h=link)。
+### 安装依赖
+* 打开命令行输入:
+~~~
+npm install
+~~~
+安装Node的库 fs-jetpack 用于对文件操作
+
+### 操作
+首先进入tools
+* 运行 BuildBeforeSetting.js 对项目初始化
+然后进行构建工程，
+* 构建Android 工程 选择link模式
+![link](https://upload-images.jianshu.io/upload_images/2315803-f28aec8ccdff1858.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)
+进入tools后
+* 运行CopyHotFiles.js 把热更新文件放到hotUpdateFiles文件夹
+* ModifyFileTime.py and ZipFile.py 对hotUpdateFiles中zipDir变量内文件修改时间（用于生成zip后，进行MD5后，md5信息不变）、zip压缩（用于更新时可以减少下载请求，提高热更速度、与更新文件的稳定性）
+* 运行VersionGenerator.js 对hotUpdateFiles进行md5得到版本信息
+* 运行ExportHotupdateDir.js 得到热更新资源到exportHotUpdate文件夹
+
+### 支持https
+* 打开工程，修改libcocos2dx工程中Cocos2dxDownloader.java类。找到new AsyncHttpClient() 修改成new AsyncHttpClient(true, 80, 443)
+* 参考文章：https://forum.cocos.com/t/https/52302
