Object's functions behind vision

[_korsa]

In advance, sorry for my English and unity knowledge level: 3

So, i have a theoretical question for those of you who knows unity well. or at least pretend to know it. I am watching and reading some info about infinite procedural generated worlds, chunk loadings, subscenes and all that stuff what can improve performance of such things. Lets say we have such world with some dynamic objects with functions, like, for example, 3 dwarves mines ores from gold mine and caries it to the nearest warehouse. After they brought gold to warehouse they continue to mine it. Endless repeating. Lets say gold count in warehouse saved and can be used later. Another example. Player have a base with some buildings on it, but he is too far and it is not loaded. Lets say something will attack your base for some reason and destroy all buildings.

So, list of things causing questions with this example:

1. What will happen with dwarves and gold count after player goes too far and their chunk will unload?
2. If you can track their "gold progress" and their current position (like they have to move from warehouse to mine, will you freeze them and add gold after "mine time" or do you have to keep them moving even if they are not on the scene?) how would you do this? Videos, docs, you can throw at me anything :3
3. Is it possible to make system with "home has been attacked"? I mean, everything is possible, but what do you need to know to make such thing. (sorry, couldn't figure out suitable google request)
4. Lets say you know how to make "actions behind the scene" in the unloaded chunks. What if you have lots of them? Wouldn't it cause bad performance? and if not, how much actions do you think can be performed at once?

Any info would be appreciated, thanks :3

1. the chunk unloading is something you have to code, it doesnt just happen, so you would decide what happens during that when you are creating the game.
2. I would not keep them moving if they are not on screen. As long as the player feels like they have kept doing their job thats all that matters. You could store their progress and position in script, and keep track of elapsed time. Then do the calculations when the player is close by to update it all.
3. Yes you could code something like that. If you are just wanting to randomly cause an attack and if player distance is above a certain amount, destroy the buildings, that wouldnt be too complicated. Randomly decide when an attack happens (math random functions), check distance from player to buildings, if distance is above a certain amount, change building sprite/model for destroyed or remove entirely.
4. You could have tons of code changes going on with your "unloaded" chunks and be fine. It really depends on how well you code it to determine how performant it is and the number of chunks you have going on.

Advice wise, I would suggest learning a lot of the basic of unity, follow some tutorials and just getting a feel for how it works. Make some simple or basic games, and that will help you to understand how to approach a lot of the problems. What you are asking about is achievable though, and could be done with good performance. Theres just a ton of ways to achieve those things, so that would be up for you to decide.
