Well, I don't know if this is the correct way but what I do is to create a new container with a unique ID (if it is a plug-in, I create a new container with an ID equal to the plugin ID).
Inside this container, I place all the data that I need.
And then, I add this container to the container of every object that I need to store the state.

Hi Rui.
Thanks for the answer, I kinda was expecting the basecontainer, but honestly I have no idea where to start. So I create a basecontainer like this:
bc = c4d.BaseContainer()
bc.SetString(1, "test")
bc.SetId(1234)
print bc.GetId()
print bc[1]
Easy enough and works without a problem, but how do I store this specific container in the document/file? The SDK says follwoing:
It is recommended that you use the available containers to store your own values as well. That way they will be automatically saved. However, if you want to store values in the top level of for example an object container, you'll have to use a unique id.
But I have absolutely no idea how to get an "available container" that will be automatically saved, or how to add to an objects container. Or is adding to an objects container as simple as the follwoing code (given you have an object selected) :
op[1234] = "test"
I stumbled yesterday upon this, but it seems way to easy to be the right way. Even if I store a new basecontainer within the document/file, how do I access it. Logical would be doc.GetBasecontainer(id) but there isn't a function like this.
Thanks in advance.

Hi Phil,
You can simply store a new BaseContainer in a document:
doc[123456789] = bc
And in an object:
op[123456789] = bc
This container can be accessed at any time and is automatically saved.
Don't forget that BaseDocument and BaseObject are child of BaseList2D, BaseList2D child of GeListNode and GeListNode child of C4DAtom.

So it is that easy?
Thank you very much, I will give it a try. One last question: is it possible to delete these containers or reset the allocation?
doc[123456789] = None
gives me an error: TypeError expected c4d.BaseContainer, not None.

It seems calling
del doc[123456789]
deletes the assigned container.

Interesting stuff! Don't know why I didn't think of this myself.
Is there also a way to store arbitrary data (like custom python classes) in a basecontainer? Whenever I try, only a -1.0 float value is stored. In the documentation of the basecontainer object we have a method called GetCustomDataType() but no corresponding set method.

It isn't possible to store Python classes in a container. Custom data types are for example FontData, SplineData, InExcludeData etc. These are special data types that CINEMA recognizes.

Thats what I thought! Luckily I've found a workaround by now, that makes it possible to store classes in a basecontainer nevertheless.
Python has a standard module called pickle. It serializes Python objects into ASCII or binary strings. Because Strings are accepted data types for containers I can store whatever object I want using this technique.
If your code relies on speed you should use cPickle, which is written in native C and therefore lightning fast.
Hope that helps somebody out there who was struggling with the same problem.
