Hi,

I have a tool that purely generates custom data and does not modify the scene. However, I would like to add my custom data to the undo list. Is it possible? There is no CopyTo function and undo is not added to the c4d undo stack.

What are my options?

Thank you

Howdy,

Could you possibly use a SceneHookData? It seems to inherit from a NodeData which has the CopyTo() function. I don't know if it is of any use, though in your situation.

Adios,

Howdy,

Yeah, on double checking, the only way to add an undo is with BaseDocument::AddUndo(), and a Scene Hook isn't associated with a document like objects and tags are.

Could you possibly use a hidden tag? The only thing I could see with that is which object it would be on, and what if the user deletes that object. It's too bad there's no way to create a hidden object.

Adios,

The problem is that my tool doesn´t edit the scene or current object. It also works in any empty scene so that kind of erases such options.
