Questions about variables saving & scene changing

[Lucian1899]

Hi! Thank you for your patience in previous questions, sadly...here I am again.

I'm making a 2D AVG with this nice tool, and I have some questions about variables saving & scene changing.

1. I put Dialogue Manager in every sence, and I untick the "Don't Destory On Load", I wonder if it will affect data saving?

2. I am confused about saving system. I have already put variables and quest states in Initial Database, but they can't work in new scene. In my game, scene changing is only via button clicking, here is my loadscene script:

Code: Select all

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using PixelCrushers.DialogueSystem;

public class ChangeScene : MonoBehaviour
{

    public string targetSceneName = "SceneB";

    public void OnButtonClick()
    {
        
        PixelCrushers.SaveSystem.LoadScene("SceneB");
}

Really sorry for lacking coding knowledge, could you please tell me if my script is correct? Did I miss any methods? And what saving component should I use in each scene? Thank you so much！

Hi,

Why did you untick Don't Destroy On Load?

In any case, make sure to set up the Save System. This includes adding a Dialogue System Saver component, which will save variables when changing scenes. (Remember to assign a unique key to the Dialogue System Saver.)

Hi,

Why did you untick Don't Destroy On Load?

Because I made some mistakes in hierarchy or UI at that time...anyway, I can save variables and quest states now, but here is a new question: I couldn't save the old scene when I return to it.

In the manuel, I found that

The state is saved in memory, in the property SaveSystem.currentSavedGameData. After loading a scene, the save system will apply that scene's saver data from the in-memory SaveSystem.currentSavedGameData.

and

In C#, call SaveSystem.BeforeSceneChange() and SaveSystem.RecordSavedGameData() before changing scenes and SaveSystem.ApplySavedGameData() after changing scenes if you're using some other method to change scenes.

But I am really confused about it, could you please tell me how can I fix my scene changing script above and how to use the property? And my script reported a new error:

NotImplementedException: The method or operation is not implemented.
PixelCrushers.SaveSystem.LoadScene (System.String sceneNameAndSpawnpoint) (at Assets/Plugins/Pixel Crushers/Common/Scripts/Save System/SaveSystem.cs:863)

I'm not sure where I did wrong, sorry for my coding knowledge.Thank you so much!

Hi,

I recommend setting up the save system: Save System Setup.

Then use the save system to change scenes: Changing Scenes.

Hi,

Thanks, I think I have set up the save system.

As for Changing Scenes, the manual lists 5 techniques and I'm not sure I should use the first or second? And does scene changing script belongs to "some other method to change scenes" that mentioned in technique 2? Really appreciate your patience.

Hi,

The 5 different options all do the same thing. The Dialogue System provides the different options to give you flexibility in what you want to do.

If you want to change scenes while a conversation is playing, I recommend using the LoadLevel() sequencer command.


The second option (SaveSystem.BeforeSceneChange(), SaveSystem.RecordSavedGameData(), etc.) is only for when you're using a different method to change scenes, such as a third party scene-changing asset. In cases like this, it's sometimes not possible to use SaveSystem.LoadScene or the LoadLevel() sequencer command because the third party asset isn't flexible enough.

Hi,
Thanks Tony, the first option worked, and I found my mistake...actually, I forgot to add Active saver component to some gameobjects, so I thought I didn't save the old scene. Thank you for your patience again.

Happy to help! I'm glad you found the issue.
