Undo.RegisterCreatedObjectUndo

Parameters

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.
