How to use my own profiler on Unity's standalones?

Unity Engine

Hi,

I’m trying to use a .NET profiler (I tried JetBrains dotTrace and ANTS profiler) to profile a standalone made with Unity.

Basically, I build my project as a “PC, Linux & Mac Standalone” application, with “Development build” checked (or not, tried both) so it creates a .exe file… let’s say test.exe.
Then, I launch test.exe from the profiler. The standalone starts normally, but the profiler doesn’t detect it.

So I came to this question: how can I use a profiler such as JetBrains dotTrace to profile my game?

Did you work out how to do this?

It should be possible , unity has a blog entry about the topic

@fffMalzbier . Thx for tip. I tried xperf, it does give details about the unity process, but it it does not go down to the code level.

I have been googling and it looks like the only profiler that can be used to analyse code unity is the inbuilt profiler.

It is a shame, because I use ANTS at work and I like it better than the UNity profiler.

It’s possible that dotTrace would work if you’re building a Windows Store App, but I’ve not tried it. The rest of the time the apps you build aren’t using the Microsoft .NET Framework, and therefore dotTrace won’t work with them.

Necroing, as this was one of the only results when I googled this.

Profiling works fine in dotTrace, build with mono as your scripting backend, check “Script Debugging” etc then launch with dotTrace unity profiling mode: https://blog.jetbrains.com/dotnet/2019/04/03/profiling-mono-mono-unity-apps-windows-macos-linux/
