Error when trying to connect nodes in prefab edit mode

[Lupos]

I discovered an error when trying to connect nodes in runtime when prefab editor is open.

Code:

[Curvy] Couldn't find Curvy Global Manager. Please raise a bug report.

Hi

What version of Curvy Splines where you using?

From reading the stack, I see that Curvy Splines does not find the _CurvyGlobal_ object, and could not create it. The latter happens as far as I know either while destroying a scene, or when in prefab mode. Were you in one of these situations?
If you can provide more information and/or reproduction case, I will hopefully be able to fix the issue.

Version: Curvy Splines 8.6.1
And yes as the op stated, it was in the prefab editor.

Sorry, my bad. I will take a look at this issue very soon. If you can easily send me a reproduction case, please do that will make the debugging process easier and faster.
Thanks and have a nice day

Hi

Creating connections while in prefab mode is not allowed. This is an unfortunate consequence of how things were designed initially:
The issue comes from the fact that connections are stored in a separate object, the _CurvyGlobal_ object which has a component of type CurvyGlobalManager. Because of this, creating a connection in prefab mode is not allowed, since it would modify an object that exists outside of the prefab.

A work around for this limitation could be to make your script check if it is running in prefab mode (PrefabStageUtility.GetCurrentPrefabStage() != null) and create the connections only when not in prefab mode.

The error message you got was misleading. Sorry for that, I will correct the message in the next update.

Did this help?
