[ExecuteInEditMode] and Prefabs

Unity Engine
1

Hello

I’m currently doing a bunch of stuff in EditMode with one of my GameObjects. The GameObject works fine (switching between Scene and Game) as long as I DON’T Prefab it and use a Prefab instance. If I do, public variables I modify in C# script are lost when the game is run.

For example if I drag in a Prefab and modify an integer in the Inspector View, let’s say I set it to 10. It remains 10 when I run the game. But if I change that integer from C# script instead (for example in the Update() function), it reverts back to the Prefab default on game start.

Is there a way for instances of Prefabs to preserve their public variable values when I modify those variables in script instead of the inspector?

I hope I am explaining myself clearly!

OK…so I discovered this, which I think does what I need.

Undo.RecordObject(this, “Change description”);

Spent all night trying to figure this out without success. Post a question on the forums and find the answer myself 5 mins later!
