Unity exe sharing data or exposing functions to a non-unity exe

Hello! I’ve been trying to make a direct connection between a Unity executable and a non-Unity executable without having to use network services; I just want to be able to send continuously an array of vectors from the non-Unity application to the Unity application while both are running at the same time.

Is this possible? So far I tried both of them sharing a dll with a variable within, but my understanding of dlls was amiss as it seems each program uses the dll as a different instance for each. Do you know of any other approach I could look into it?

Thank you in advance :slight_smile:

Named pipes would work.

Great! Will look into it!

Thank you very much! :smile:

I’ve been trying to do something similar and was kinda successful using the data_seg pragma. I still haven’t tested it extensively, tho. Would you happen to know if there are any disadvantages for this approach instead of sending messages using named pipes?

That looks like a pretty good way to do it, you just need to make sure you do the synchronization correctly (using global mutexes I assume).

I had never heard of such class! Where should this be implemented? On Unity’s side or dll’s?

7

You mean global mutex? You’d use it in the DLL before accessing the shared data.

Oh my! I did not see you had responded my question! My apologies!

In the end, the approach I implemented wasn’t suitable for what we are trying to do and had to start over.

Still, thank you!
