1.宏定义：添加 HOTFIX_ENABLE 到 'Edit > Project Settings > Player > Other Settings > Scripting Define Symbols'。
（注意：各平台需要分别设置）

2.生成代码：执行 'XLua > Generate Code' 菜单，等待Unity编译完成。

3.注入：执行 'XLua > Hotfix Inject In Editor' 菜单。注入成功会打印 'hotfix inject finish!' 或者 'had injected!' 。";

1. Define: Add 'HOTFIX_ENABLE' to 'Edit > Project Settings > Player > Other Settings > Scripting Define Symbols'.
(Note: Each platform needs to set this respectively)

2.Generate Code: Execute menu 'XLua > Generate Code', wait for Unity's compilation.


3.Inject: Execute menu 'XLua > Hotfix Inject In Editor'.There should be 'hotfix inject finish!' or 'had injected!' print in the Console if the Injection is successful.";
