I’m not sure if I named this properly, but what I am trying to figure if this is even possible, if it is, could you please lead me to what I need to look into?
What I’m wanting to do is build stuff onto my map, and save it (it’s Online) so I guess you could look at it from a Minecraft prospective or Simcity online, you build your maps with your buddies, and save it if you want to turn it off.
The answer to any question that begins with “This other game does it, can Unity do it too?” is always yes. Unity has equivalent powers to pretty much every other engine out there.
You will want to run a database for storing saved games. You’ll also need to run some server side code if you want to manipulate the data while users are not playing. You can do this all yourself. Or you can investigate 3rd party solutions. Both Parse and Photon are worth investigating. There are others.
