How to programmatically break prefab instance upon pressing Play

Question

Is there a way to break a prefab connection in script when I hit the Play button (or when the game starts)? I'm using an asset from the asset store that does not work in play mode unless the connection on it is broken. I know of PrefabUtility.DisconnectPrefabInstance, but it appears like it can only be executed in Edit mode? Is this true?

Thanks!

You can use the onPlaymodeStateChanged callback to perform your code right after the play or pause button is pressed. You'll need either a custom inspector or an editorwindow to be able to subscribe to the event.

Why not in Start or Awake?

Because the OP said he wanted it when he presses the play button but in edit more because he is using PrefabUtility.DisconnectPrefabInstance. That's in the UnityEditor namespace.

Though I have always been under the impression that links to prefabs are broken when entering the play mode...
