Saving persistent objects on a tiled map (multiplayer)

I’m building a survival/crafting game where I would like to save some basic data on placed and dropped objects around my tiled world map (ex. dropped weapons, growable crops and placeable structures). Ark is a good example on a recent UE4 game doing just that.

I’m trying to figure out a way to serialize each object and save it per level tile, but I have no clue as to how. I tried some stuff with PHP and JSON but it got me nowhere.

I looked at the SaveGame feature in Unreal but this does not appy to multiplayer sessions. I already know this will probably be a (big) custom code job in terms of work, I just need a push in the right direction.


Hey, did you actually figured this out somehow?
