How to debug on linux with vs code?

Unity Engine

Ok tried whether my speculation about standalone build are true or not. Was able to get standalone build debug working in following way:

  • In build options enable “development build” and “script debugging”

  • [optional] in the build output folder edit build_folder/NAME_Data/boot.config . Change managed-debugger-fixed-port to the port value you want to use.

  • install mono debug vscode extension Mono Debug - Visual Studio Marketplace

  • Create the debug config in launch.json example below

  • start the executable

  • use the “mono attach” debug target

In the port field specify the same port you wrote in boot.config.

{
            "name": "mono attach",
            "type": "mono",
            "request": "attach",
            "address": "localhost",
            "port": 123123
        },

If you didn’t specify a fixed port in boot.config Unity will choose a random one each time. You can find out which port it chose in Player.log. Near the top there should be a line similar to:

Starting managed debugger on port 56189

Since it was somewhat generic mono debugger. I guess other tools which support debugging mono might work in similar way.
