微信分包教程

工具：

修改文件目錄：

起始：

需要修改的地方有 game.json, game.js, main.js

將 raw-assets 分包爲 assets1, assets2，並且壓縮配置上標記文件 game.js

修改後：

修改三個文件 game.json, game.js, main.js

game.json (修改 subpackages對象的屬性)

{
  "deviceOrientation": "portrait",
  "networkTimeout": {
    "request": 5000,
    "connectSocket": 5000,
    "uploadFile": 5000,
    "downloadFile": 5000
  },
  "subpackages": [
    {
      "name": "assets1",
      "root": "res/assets1"
    },
    {
      "name": "assets2",
      "root": "res/assets2"
    }
  ]
}

game.js (保證在引擎渲染前調用nodejs模塊解壓文件到微信的文件系統)
