public static function RegisterCreatedObjectUndo(objectToUndo: Object, name: string): void;
public static void RegisterCreatedObjectUndo(Object objectToUndo, string name);

Parameters

objectToUndo The object that was created.
name The name of the action to undo. Think "Undo ...." in the main menu.

Description

Register an undo operations for a newly created object.

When the undo is performed the object will be destroyed. All newly created objects that are part of undoable state should be registered with this function.

Note: Object destruction works the same way as it does for Object.Destroy (except for the delay). This means that GameObjects will be destroyed along with all their child GameObjects.
