###  小游戏爱上云开发



### 游戏简介

**游戏名称：**  娇娆向日葵

**作者：** Javen

**版权：** 深圳市紫石文化传播有限公司

**开发语言：** JavaScript

**游戏引擎：** Cocos Creator v2.1.2

**注意事项：** 允许免费用于学习交流，切勿商用否则后果自负



玩法：随着音乐节奏，点击左右按钮控制场景中人物形象播放速度，操作反应越快燃烧的卡路里越多、人物形象播放速度越快。

核心功能：

1. 微信授权登录
2. 好友排行榜
3. 游戏个性化分享
4. 小程序-云开发(获取用户信息、加载配置数据、上报成绩、排行榜)
5. 资源动态加载(龙骨动画、预制资源)
6. 资源远程加载(打包后将资源放在服务器首次启动时进行远程加载)
7. 场景切换时显示加载进度



### 游戏场景介绍

该游戏比较简单，总共只使用到四个场景加微信开放域项目。

- First 场景，此场景只有一张图片，此图片与游戏包一起发布。是为了解决 IOS 进行远程加载时会出现短暂黑屏的问题
- Welcome 公司 IP 形象宣传页动画
- Loading 加载数据的过渡场景。
  - 初始化云开发环境
  - 获取 openId
  - 获取用户信息
- Home 游戏主场景
  - 初始化UI(各种 Node 节点、倒计时组件、异步加载龙骨动画、动态加载预制资源)
  - 判断是否授权，如果没有授权就动态创建button
  - 游戏逻辑实现
  - 游戏成绩上报
  - 好友排行榜

### 云数据库

点击图三中的 `云开发` 根据流程开通即可使用 `云函数`、`云储存`、`云数据库`

### 核心功能实现

参考文档：

- [云开发官方文档](https://developers.weixin.qq.com/minigame/dev/wxcloud/basis/getting-started.html)
- [微信小游戏 API 文档](https://developers.weixin.qq.com/minigame/dev/api/)

微信 API 常用接口的封装

- 初始化云环境
- 封装调用云函数方法
- 获取用户信息
- 创建用户信息按钮
- 调用云数据库将最新成绩上传至云端
- 微信广告接口封装

### 适配不同平台

思路: 使用 `cc.sys.platform`  获取平台信息再做接口适配，目前只实现了  `cc.sys.WECHAT_GAME`  的接口如下： 

```javascript
const WxApi = require('./WxApi');

var wxApi = new WxApi();

function initCloud () {
    wxApi.initCloud('pro-15ec75');
}

function callFunction (funcName, params) {
    return wxApi.callFunction(funcName, params)
}

// 获取设置,判断是否授权
function getSetting (scope) {
    return wxApi.getSetting(scope);
}
// 登录获取code
function login () {
    return wxApi.login();
}

function getUserInfo () {
    return wxApi.getUserInfo();
}

// 显示准发按钮
function showShareMenu () {
    wxApi.showShareMenu();
}

// 转发·小程序
function onShareAppMessage () {
    wxApi.onShareAppMessage();
}
// 主动拉起转发
function shareAppMessage () {
    wxApi.shareAppMessage();
}

function showModal (title, content) {
    wxApi.showModal(title, content);
}

function showLoading (title) {
    wxApi.showLoading(title)
}

function hideLoading () {
    wxApi.hideLoading();
}

// 动态创建获取用户信息按钮
function createUserInfoBtnByImg (left, top, imgUrl, width, height, callBack) {
    return wxApi.createUserInfoBtnByImg(left, top, imgUrl, width, height, callBack);
}

// 动态创建反馈按钮
function createFeedbackButtonByImg (left, top, imgUrl, width, height, callBack) {
    return wxApi.createFeedbackButtonByImg(left, top, imgUrl, width, height, callBack);
}
