Any idea? Many Thanks,

The game is fot IOS, my Unity version is 2019.2.8f1, my AC version is 1.69.2

So you're saying that this only occurs if you load the game beforehand?

Try opening up LevelStorage.cs, and paste the following into line 305:

if (allLevelData == null) allLevelData = new List<SingleLevelData>();

Does that resolve the issue?

Beautiful, Chris! It work! Thank you very much. Where was the problem? On my project or is a bug on Adventure Creator?

voceradio

hi, Chris. I’ve checked that your fix work (I don’t have already understand If i must fix every my future project or it is a bug that you’ll fix in future upgrade) but many things don’t be saved in autosave, like: follow npc, trigger on/off, position of NPC ecc. I’ve add every Remember component but the issue persist. Thanks for Your Help. 😊

Ok, don't work also in a new fresh project.
I've created a new empty project importing only Adventure Creator 1.69.4 on Unity 2019.2.8f1 Windows 10 64bit.

I've add 1 CUBE 3D and 1 SPHERE 3D.
I've put 2 hotspot, one on each and 2 Remember hotspot.
I've create 2 INTERACTION with: disable hotspot and save (autosave).

When i PLAY, i click on the CUBE, the interaction disable the hotspot and save.
I press STOP.
I press PLAY again and i LOAD the autosave from AC Menu default.

The hotspot on the CUBE is active and if i click on the cube i get the same error:

NullReferenceException: Object reference not set to an instance of an object
AC.LevelStorage.SendSceneToData (AC.SubScene subScene) (at……

For me is very strange. I've read many many post on this forum and you said many time that the hotspot remember is enought for saving the state.

Help!

Thank you, Chris.

I've found a thing… The issue appear only on IOS Platform.
If i switch on "PC, MAC & LINUX" or "ANDROID"… all Hotspot remember works fine as aspected.
Are there a solution for IOS platform?

Thanks

ChrisIceBox

What iOS version are you building to? I shall look into this.

Does it work if you enable Json saving by checking Save in Json format? (Experimental) at the top of the Settings Manager?

voceradio

Hi Chris! Yes! Changing the save format in Json (experimental) all works on iOS!
I'm so happy and grateful to you. Finnally i can close my new 3d adventure game!
When ready i'll send to you a link for download it (if you like and you have time).

Thanks!
Paolo
