Persistent world with UE4 (not an MMO)

If each of the modifications is an Actor, and the Actor applies its changes to the world, then all you need to do is make sure that you re-create the same Actors in the same order, and the world will be re-created for you.

For small games in a small world, you can probably even do it without worrying too much about the necessary low-level optimizations, as long as the basic “periodic checkpoint” is still there.

I don’t know exactly how far you’ve gotten with the “actually modify the world” logic – if you have that working, turning that into networking should be possible.

We don’t have any logic for world modifications yet, that’s kinda sad part when you are creating game engine for 4 years instead of making an actual game I am talking about Javascript version now. Obviously with UE we don’t have anything at all as I only started exploring it two weeks ago and I was trying to figure out how to actually do necessary stuff we need till I bumped into this.

Building world dynamically from actors based on data is probably one thing, but then you need to keep it updating based on additional incoming data. Or even remove actors if player is too far away or that actor was removed for some other reason (someone has picked up item).

Still it’s rather scary for a first encounter with C++ to be about serialization and networking. Not sure if I am up for such big task. Instead of developing game engine in comfortable Javascript I would be developing engine in uncomfortable C++. I am not thrilled about that for sure…
