Opentrack is software for head tracking for example using webcam that can send xyz position and rotation (although i'm only interested in position) through UDP. How can I reveive these UDP packets with Unity as simple as possible without any external libraries? I would also want to avoid freezing main update loop with that but i have no idea on how to do that. I'm pretty new to Unity and have no idea how to do something like that. I couldn't find any code on the internet that wouldn't freeze the update loop.
