一、VSCode安装EmmyLua插件

二、拷EmmyLua的文件到项目目录中

C:\Users\用户名\.vscode\extensions\tangzx.emmylua-0.5.13\debugger\emmy\windows\

中的x64和x86拷到Tool\emmylua\中

D:\Project\Assets\
D:\Project\Tool\emmylua\x86\...
D:\Project\Tool\emmylua\x64\...

三、添加以下代码至启动的lua中

local function startDebugger()
    --- 把emmylua的dll所在路径添加到lua的搜索路径中去
    package.cpath = package.cpath..';.\\Tool\\emmylua\\x64\\?.dll'
    local dbg = require("emmy_core")
    dbg.tcpConnect('localhost', 9966)
end

local ret, errstr = pcall(startDebugger)
if not ret then
    print(errstr)
end

四、VSCode添加启动配置

在 .vscode/launch.json中，配置 emmylua

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "emmylua_new",
            "request": "launch",
            "name": "EmmyLua New Debug",
            "host": "localhost",
            "port": 9966,
            "ext": [
                ".lua",
                ".lua.txt",
                ".lua.bytes"
            ],
            "ideConnectDebugger": false
        },
}

五、先启动VSCode，再打开游戏

附：EmmyLua+C# 调试的VSCode之launch.json配置

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "emmylua_new",
            "request": "launch",
            "name": "EmmyLua New Debug",
            "host": "localhost",
            "port": 9966,
            "ext": [
                ".lua",
                ".lua.txt",
                ".lua.bytes"
            ],
            "ideConnectDebugger": false
        },
        {
            "name": "Unity Editor",
            "type": "unity",
            "path": "./Library/EditorInstance.json",
            "request": "launch"
        },
    ]
}
