来自HybridCLR官网：

 安装HybridCLR | Focus Creative Games (focus-creative-games.github.io)

 可以自行学习查看

首先在Unity添加 HybridCLR

细心的可以看到官网有这个下载网站   怕你们找不到我就放在下面了

https://gitee.com/focus-creative-games/hybridclr_unity.git

 如果添加后有git的报错建议去git官方网站下载个最新版本  下载后要重启电脑 ！！！

接下来开始配置 

点击之后就会发现多了热更新的文件夹 

 接下来开始是代码部分

public class ABData
{
    public AssetBundle ab;
    public int num;
}

这里用到了泛型单利  不懂的自行跳转到本人的泛型单利：
