Issues updating to new version
Heya,
After a long time stuck in old versions of both Unity and AC, I'm finally trying to do a complete update of both. I'm running into some issues, however, that I hope are easily solvable.
My process so far has been as follows;
- Updating the Unity version from 2019.3.16f to 2022.3.20f1 (a pretty substantial jump, I'm aware.)
- Due to all the compile errors and issues I ran into, I tried removing the Adventure Creator files from the project files themselves, and re-importing it with the latest version. The old version ran on v.1.70.4, and the new project is running on v. 1.81.6. (Another sizable jump, I know). I've tried simply updating the Unity version before, but I keep running into the issue of Unity seemingly not recognizing Adventure Creator as a plugin, and as such I was unable to edit or work within the framework at all.
- I re-assigned all the old Managers from the older version and hooked up the most recent update of Pixel Crushers Dialogue System as well. (I did not run the New Game Wizard, however, and I figured it'd be best to avoid that for the time being)
- I got the game back up and running once again after redoing some old scripts and setting up my old custom actions, which worked fine; this is where I'm starting to have problems that I can't seem to solve.
The main issue I'm having right now is being unable to create new objects/prefabs through the Scene Manager window. Whenever I try to create something new in a scene through the AC Game Editor, nothing happens. Pre-existing hotspots and In Scene actionlists work fine, but I can't create new ones. If I create an empty game object in the hierarchy and add an Interaction, I'm unable to assign it to anything in the Scene Manager, either.
I get two errors whenever I try to create a new object;
GUI Error: Invalid GUILayout state in AdventureCreator view. Verify that all layout Begin/End calls match
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
and
NullReferenceException: Object reference not set to an instance of an object

If I try to create a new actionlist, for example, from either the Inventory Items or the Menu Manager, that works just fine - the new actionlist is just added to my project files, with no issue.
I understand that there's a million things that could go wrong with how I've gone about the updates, and that this is most likely very difficult to troubleshoot, but if any particular red flags pop up I'd love to hear about them. I'll obviously provide you with as detailed information as possible about anything else you might need to know. Thanks for your help, and hopefully this isn't as difficult to solve as it seems at the moment.
Howdy, Stranger!

I tried moving the prefabs folder back into the Adventure Creator folder in the project files, and that seems to have done the trick - I'm able to create any prefab object in the Scene Manager now.
I'll go ahead and leave this topic up, in case there's anything that comes to mind that I should make sure to edit or fix - so far, the game seems to be running with no issues, but if there's something important that might not be immediately noteworthy (regarding upgrading both AC and Unity in this highly unstable way) I'd love to know.
If things are working again, great - a few notes that come to my mind:
Yeah so far AC seems to be working without any problems, which I'm very happy about. I did actually update AC in the old project files before updating Unity, which definitely helped - I tried it before without updating AC and had no success.
When updating the Unity version I've always ended up with Unity not recognizing AC as part of the project and plugin files, however. If one updates AC before Unity, is there a way to re-initialize AC as part of the project without re-importing the assets through the package manager?
If AC fails to initialise, it's most likely due to a compilation error as noted above. Check the Console window for error messages if this occurs - if you share them here, I can help decipher them.
