Question about active saver

Hi,
I have an UI canvas in my first scene and set it as DontDestoryOnLoad，it has several layers and many child objects, and I add an active saver component to it. During the game, some of its child objects will become active, but here comes the save problem.
I use On Conversation End trigger to activate those child objects, their active state can be saved when I change sences, S/L, back to main menu（only in play mode）.but when I back to edit mode and play the game again, I found their active state can not be saved when I load the game. Could you please tell me which step I did wrong, or I missed something? Thank you!

Hi,
ActiveSaver and MultiActiveSaver components must be on GameObjects that are active when the scene starts. Is your ActiveSaver component on a GameObject that is active when the scene starts?
When you enter play mode a second time, are you loading a saved game? The save system will not automatically restore your last saved game. You can use an AutoSaveLoad component to do this, or you can load a saved game manually using the C# method SaveSystem.LoadFromSlot(#) or SaveSystemMethods component.

Yes, the father object is active when the scene starts.
When you enter play mode a second time, are you loading a saved game? The save system will not automatically restore your last saved game. You can use an AutoSaveLoad component to do this, or you can load a saved game manually using the C# method SaveSystem.LoadFromSlot(#) or SaveSystemMethods component.
I think I loaded a saved game, I'm using the Dialogue System Menu Framework. Here are my menu system and dialogue system, I don't know if I did something wrong, thank you!

How are you changing scenes? Please see
How To: Change Scenes With Save System. See also:
How To: Manage Player Controls and Scene Changes.
When you're in the main menu scene, are you using the "Load Game" or "Continue" buttons to load a saved game?

Hi,
How are you changing scenes?
I use PixelCrushers.SaveSystem.LoadScene("sceneName").
When you're in the main menu scene, are you using the "Load Game" or "Continue" buttons to load a saved game?
Yes, I use LoadGamePanel.LoadCurrentSlot() and SaveHelper.LoadLastSavedGame.
I've tried to watch a regular GameObject's active state in another scene, and it can saved perfectly. So I think maybe the UI canvas itself has the problem. Here's my custom persistent singleton script, I'm not sure if it is correct and related to this problem.
Code: Select all
using UnityEngine;
public class DontDestroy : MonoBehaviour
{
private static DontDestroy instance;
private void Awake()
{
if (instance == null)
{
instance = this;
DontDestroyOnLoad(gameObject);
}
else
{
Destroy(gameObject);
}
}
}
And actually, the UI canvas is using this Dynamic Panel,
https://github.com/yasirkula/UnityDynam ... me-ov-file, so I'm not sure if I should customize that Dynamic Panels Canvas script, or I should write a custom saver? Thank you!

Hi,
Is it possible that the ActiveSaver or some other component is losing its reference to the Don't Destroy On Load GameObject? Please see the How To: Manage Player Controls and Scene Changes link above for an explanation of how this can happen and how to address it.
