Hi I will pm you so we can get a dialogue going, solutions will of course become public in my plugin as soon as I develop them.

My first thought was to see if you could save before calling Super::EndPlay, but you may have to consider saving periodically, the purpose of the actor I am now spawning is to enable Async saving to occur, which you can enable in Settings. The other reason for the actor is to enable the async Level Streaming process to occur.

If no other solution is viable, I can add an option for reverting, but frankly, you are better off doing periodic async save (Which won’t drag on the performance of the server because I am fully multi-threading the save process now), this is more stable than relying on EndPlay.

And if it a save cause every player leaves, well then you don’t have to end play till you are ready.

But the advantage of the actor is now you can save in the background on periodic interval without affecting gameplay. Endplay wouldn’t give the async process time to occur anyway as I launch another thread.

Thanks for your reply. Currently we are offline, with multiplayer to come in the near future.
Right now the workaround is (VR-Game): ESC has been disabled for closing the editor/game. Within the player character, which is always existing, ESC->Save->QuitGame. This will give your actor the opportunity to suck in some fresh air

I’ve already seen your async saving in action and it looks dam good. Thats what we would need for VR to keep the game going. In your demo video you are saving a whole bunch of data of actors that are static in the world, not moving, not able to receive input. But how is async saving working out if the player is still able to input data, change object state, automatic moving objects are moving, while async saving is going? Especially in multiplayer games this is a reasonable question, cause you can’t freez the game for tons of players just cause you are doing your periodic 5min interval save.

With unreals SaveObject system it’s always: load slot->if not exist, create it->save data to it->save slot. Means you append data to the given savegame.
With your save system it is: Save. You pickup every actor with a RamaSaveComponent and store it. But how about appending only changes to an existing save like SaveObject from Unreal? Am I missing something?
