哈喽大家好，我叫人宅，很高兴和大家讲解以上的内容：

热更新插件 SimpleHotUpdate 在使用的时候很多人不知道如何自动下载远端部署好的热更新资源。我也经常远程辅助解决这方面问题，解决多了，发现都是相同问题，这里特此发一篇关于热更新的自动如何部署代码：

只需要将下面的代码复制到自己的工程Source里面：

1.目录结构

以MMOARPG工程为例

2.在自己的项目build.cs下包含SimpleHotUpdate和UMG模块 最好也把Slate 和SlateCore也打开

3.将下面的代码拷贝到自己的代码文件中

5.创建一个UMG蓝图，把丢失的字体按照格式填充好

填充这些警告的内容

6.用蓝图创建一下，把这个UI贴到视口处
