Question Script to detect when system has gone to sleep

I've looked around for this a bit and there doesn't seem to be any solid, working information out there. Essentially, I need a script that can detect when the OS has gone to sleep.

I've tried using time measurements with Unity function calls but they seem unreliable for this task (OnApplicationFocus & OnApplicationPause don't really pertain to sleeping, or at least I couldn't figure something out). I've also tried using C# power level assessment, but I couldn't get that working either.

 

There is no built-in functionality in Unity. You will need to call OS-functions for that. Those depend on the OS you're targeting.

 

Any leads for how you would do that on MacOS and Windows builds?

 

Why not use DateTime.Now.Ticks? You get an excessively large jump between frames, and the machine probably went to sleep.

Hey @Joe-Censored! I tried that (and Time.unscaledTime) in between OnApplicationFocus & OnApplicationPause and while it has a little bit of success, it's not very reliable since the frame jump could have also been because the user was tabbed out of the application and did something that might have caused a frame spike.
