Tells Cinema 4D to start building a list of undos into a single undo action for the user.

Here is a small example how to write a redo support for newly inserted objects.

import c4d

doc.StartUndo()                     # Start undo support
cube = c4d.BaseObject(c4d.Ocube)

doc.InsertObject(cube)              # Insert the object
doc.AddUndo(c4d.UNDOTYPE_NEW, cube) # Support redo the insert operation
doc.EndUndo()                       # Do not forget to close the undo support

BaseDocument.AddUndo(self, type, data, allowFromThread=False)¶

Adds an undo type to the list of undo operations started with StartUndo().

Note

Always has to be called before a change is made.

In the case of the creation of a new object the call is done afterwards, after insertion into the document/object/track/sequence but before calling subsequent functions like BaseDocument.SetActiveObject() which creates another undo:

tag = c4d.UVWTag(op.GetPointCount())
op.InsertTag(tag)
doc.AddUndo(c4d.UNDOTYPE_NEW, tag)
c4d.EventAdd()

Parameters

type (int) –

The undo type:

UNDOTYPE_NONE	None.
UNDOTYPE_CHANGE	Any change to an object, including hierarchy modifications; modification in positioning (object has been moved from A to B), substructures etc. (Needs to be called before the change.)

UNDOTYPE_CHANGE_SMALL	Change to local data only (e.g. data container), no substructures (e.g. no tags on an object) and no children. (Needs to be called before the change.)
UNDOTYPE_CHANGE_SELECTION	Change to point/poly/edge selection only. (Needs to be called before the change.)
UNDOTYPE_NEW	New object/node/tag etc. was created. (Needs to be called after the change.)

UNDOTYPE_ACTIVATE	Automatically managed by `BaseDocument.SetActiveObject()`/`SetActiveTag()`/`SetActiveMaterial()` etc. No need to use manually.
UNDOTYPE_DEACTIVATE	Automatically managed by `BaseDocument.SetActiveObject()`/`SetActiveTag()`/`SetActiveMaterial()` etc. No need to use manually.
UNDOTYPE_BITS	Change to object bits, e.g. selection status. (Needs to be called before the change.)

Parameters: multiple (bool) – This parameter only matters if this method is called between AddUndo() and EndUndo(). If multiple is True then all the AddUndo() steps will be undone. Otherwise only the last AddUndo() step will be undone. If EndUndo() has been called then all steps are always undone.
Return type: bool
Returns: True if successful, otherwise False.
