Official introductory documentation reference：

https://focus-creative-games.github.io/hybridclr/start_up/#安装和环境搭建

1.First download the two packages 一个解释器 一个修改Unity IL2CPP 的代码包 （注意Unity 版本要求为2020.3.33 The author is also expanding on subsequent editions）

解释器下载：
https://github.com/focus-creative-games/hybridclr

2020.3.33 IL2CPP Library modification download：
https://github.com/focus-creative-games/il2cpp_plus/tree/2020.3.33

Download the official example project：
https://github.com/focus-creative-games/hybridclr_trial.git

The corresponding download is completed as shown in the figure below

2 拷贝 hybridclr/huatuo 目录 到 il2cpp_plus/libi2cpp 目录下

3. 复制第2步修改的libil2cpp 文件夹 替换掉Unity 2020.3.33 编辑器的libil2cpp文件夹（It is recommended to back up before replacing）

找到对应Unity 安装目录 打开


搞定 The environment is set up You can open the example project to see it

4 哦豁 报错 小问题 Look at him saying that there are fewer documents Open the directory he said to have a look

4.1 修改init_local_il2cpp_data.bat 文件 改成对应Unity 安装目录 双击运行 他会生成一个LocalIl2CppData 文件

Note that the circled places have to be changed The last two addresses Corresponding to the above fromgitdownload path

make a copy of this Add an overlay without prompting

双击 bat提示成功就可以了

可以看到 生成了一个 LocalIl2CppData 目录就可以了

5 重新打开工程 Let him load it up 就不会报错了 打开示例main场景

6 First compile a package to test （方便测试 I'll make one up firstPC包把）

6.1如果提示 IL2CPP not installed 表示安装Unity was missed when ticking 没下载Window下的IL2CPP 打包环境

打开Unity Hub 点击安装 Select the corresponding version 右键 添加模块

6.2直接点Build 选个目录 I will create a new one hereBuild 目录 Put it in here

然后等 他loading 完 看看到 有个exe 编译完成

6.3 打开 All mouse clicks can open the console You can see this print log output

6.4 现在对这个C# Make a simple modification and see

7.先编DLL

7.1 再把DLL 变成ab 包

7.2 刚刚的DLL compiled intocommon 里面 直接手动拷贝 覆盖进去（Simulate update download）

7.3 直接替换掉Build 目录下的StreamingAssets同名文件

7.4 再打开exe 看看效果

There is a print out 完美
