i finally succeeded in saving a BaseList2D userdata description (not the values)
then loading and re-applying / cloning the full definition to a different BaseList2D,
and finally copy over the values from the source to the target BaseList2D

here is a similar topic for saving / loading the values (not the description) here:
https://plugincafe.maxon.net/topic/11960/advice-for-saving-user-data/8
I made a comment there about copying the userdata values

@zipit said in Advice for Saving User Data?:

# Write the data back.
for cid, value in bc:
    descid = (c4d.ID_USERDATA, cid)
    # Check if the type of the element in op at the given descid matches
    # the data type we want to write, i.e. if the structure of the user
    # data has not changed.
    if isinstance(value, type(op[descid])):
        op[descid] = value

a notice about the code part above :
this gave me type errors and i solved it by not iterating through the bc, but instead through the ops UserData
and skipping any DTYPE_GROUP and DTYPE_SEPARATOR
(could be done also when reading the values, ofc)

    for descid, _ in op.GetUserDataContainer():
        uid = descid[1].id
        dtype = descid[1].dtype
        name = _[c4d.DESC_NAME]
        value = bc[uid]
        print "  uid={} dtype={} name={!r}".format(uid, dtype, name)
        if dtype == c4d.DTYPE_GROUP or dtype == c4d.DTYPE_SEPARATOR:
            pass
        elif dtype == c4d.DTYPE_SUBCONTAINER: 
            pass # DTYPE_SUBCONTAINER - should never happen?
        elif isinstance(value, type(op[descid])):
            op[descid] = value
        else:
            pass # TYPE MISMATCH - should never happen?

thanks zipit,

using Hyperfile looks very promising,
the Userdata Container seems to be a list containing tuples and BaseContainers,
I will try to store that into a file and report back If it works :)

Hi Manuel,

I just thought it must be possible to Message something to a CommandData plugin, too.
The idea behind the CommandData was to combine some other functionality,
but I guess i just get a new plugin ID and go the MessageData way...

best, Index

hm, somehow I cant find how to tag this as solved

Hi,

Is it possible to dump (and restore) a complete UserDataContainer?
ie. save the whole information into a definition in a python source that can be then used to auto generate identical UserDataContainers?

I'm talking about the data types and structure (groups etc), not the value content.

best, index

# IN A MESSAGEDATA PLUGIN
def CoreMessage(self, id, msg):
  if id == PLUGIN_ID:
    print "Hello World!"
  return True

# IN A PYTHON TAG (NOT TAG PLUGIN)
c4d.SpecialEventAdd(PLUGIN_ID)

hm, this seems to work using a MessageData plugin,
but isnt it possible to receive a (Core)Message in a CommandData plugin?

Thanks Manuel,

I saw this thread before, and I must study it more in depth, but one thing ...
I don't use a Tag Plugin, I use a Python Tag.
So the Plugin with the Gedialog is not connected to the Tag.

I want to send a Message from a Python Tag to a Commanddata Plugin
The Gedialog there can be Async or Modal, that doesn't matter.

Btw, another way to solve my problem would be to catch MSG_DOCUMENTINFO_TYPE_LOAD
from a Commanddate Plugin and check all Python Tags in the Scene from there.
But I read this is not possible using Python... (?)

Hi,

I do have some Python Tags and need to display a dialog to get a yes/no user decision in certain cases.
I actually did this for a long time on macos, but know now why this leads to freezes on Windows.

My first idea for a solution was to message from the python tags to a commanddata plugin, which then would display a dialog and take action.

Is that possible and how can I do that?
CallCommand() is not allowed from a python tag and something like this doesn't seem to work either:

op = c4d.plugins.FindPlugin(PLUGIN_ID)
bc = c4d.BaseContainer()  
...
op.Message(c4d.MSG_BASECONTAINER, bc)

@zipit

just FYI, the CacheInterface immediately crashes R20 but works on R21

@m_adam

Ok, thanks!
I was doing this in every Python Tag and I have 100-200 of those in the File.
I don't really need to do this, it was just a "beauty" thing... that did end up ugly :-D

hi zipit,

thank u a lot for those tips ! :)

about the CacheInterface i dont know if i do that right,
but if i select a cube and execute in the script manager
R20 crashes right away .-)
