How do i make a dedicated server that you directly connect to?
If i have my own server(s) do i still need unet?
Is there a way to approximate how much ram per player you need?
First step is to choose a network API which supports dedicated servers. The specific instructions would depend on the chosen API, and should be well documented since this is a pretty basic set up question.
Unet was deprecated well over a year ago, so no you should not choose Unet. If you really like Unet you could give Mirror a try, which started life as the Unet HLAPI code base.
Depends on the network API again. Unet though was notorious for very high memory usage, since it would preallocate all memory needed for whatever the max players are configured for. Most network API’s don’t do that though.
