I wonder if I could save the game in some specific scenes or specific script's line in-game?
For example:
In the scene, players save between 2 big scenes, and I want when they load that save file, the game will start in the previous script's line or some specific line that made different choices.
Anyone can help me with this?
I really need it, please!
You can use @save (https://naninovel.com/api/#save) to save to a quick save slot. For more complex behaviour I suggest overriding IStateManager to make the save & load system more checkpoint-based. Alternatively consider disabling the option to save during key moments by creating a custom command.

Thanks for the reply!
I thought about this but I'm not so sure about that. Since you mention it, I'll give it a try, thank you!

I tried to change the Save of StateManager script like this one
Code: Select all
public virtual async UniTask<GameStateMap> SaveGameAsync(string slotId, bool isQuickSave)
{
var quick = slotId.StartsWithFast(Configuration.QuickSaveSlotMask.GetBefore("{"));
OnGameSaveStarted?.Invoke(new GameSaveLoadArgs(slotId, quick));
var state = new GameStateMap();
await scriptPlayer.SynchronizeAndDoAsync(DoSaveAfterSync);
OnGameSaveFinished?.Invoke(new GameSaveLoadArgs(slotId, quick));
return state;
async UniTask DoSaveAfterSync()
{
if (isQuickSave)
{
state.SaveDateTime = DateTime.Now;
state.Thumbnail = cameraManager.CaptureThumbnail();
SaveAllServicesToState<IStatefulService<GameStateMap>, GameStateMap>(state);
PerformOnGameSerializeTasks(state);
state.RollbackStackJson = SerializeRollbackStack();
state.CurrentScene = SceneManager.GetActiveScene().buildIndex.ToString();
state.SWPos = SnowWhitePosition();
await GameSlotManager.SaveAsync(slotId, state);
// Also save global state on every game save.
await quickSaveGlobalAsync();
lastCheckPoint = state;
}
else
{
if (lastCheckPoint != null)
{
state.SaveDateTime = lastCheckPoint.SaveDateTime;
state.Thumbnail = lastCheckPoint.Thumbnail;
SaveAllServicesToState<IStatefulService<GameStateMap>, GameStateMap>(lastCheckPoint);
PerformOnGameSerializeTasks(lastCheckPoint);
state.RollbackStackJson = lastCheckPoint.RollbackStackJson;
state.CurrentScene = lastCheckPoint.CurrentScene;
state.SWPos = lastCheckPoint.SWPos;
await GameSlotManager.SaveAsync(slotId, state);
// Also save global state on every game save.
await SaveGlobalAsync();
}
else
{
await GameSlotManager.SaveAsync(slotId, null);
// Also save global state on every game save.
await SaveGlobalAsync();
}
}
}
}But when I tried to load it, It went wrong and... not crash nor show any bugs, it's just... very wrong and not like the quicksave file.
I did something wrong in there? I can't find any clue to fix this ;;-;;
I don't recommend changing the Naninovel code but instead override IStateManager (https://naninovel.com/guide/engine-serv ... n-services) That way you can actively compare and debug the two services.
I also recommend reading on State Management if you haven't already: https://naninovel.com/guide/state-manag ... game-state
