communicate between Unity and a Windows exe?

Questions & Answers
1

I need to communicate between my Unity project and a Windows executable running on the same PC.

The Windows exe needs to send simple messages to the Unity application, and the Unity application needs to send simple messages to the Windows exe.

What’s the best way to do this? Named pipes? Windows Messaging? Sockets? UDP? Something else?

Sample code or tutorials would be awesome (I’m new to unity and C#)

@christianeide - Yes. We ended up using TCP/IP, sending JSON strings back and forth.

That seemed to be quite good performance-wise (at least good enough for our needs.) It’s also expandable should we want to talk to other computers on the network, etc.

(using Sockets, as @xxmariofer mentions)
