I am trying to set up a User Data preset. So far, I have some radio buttons. The user chooses a preset. He then makes some changes. I want him to be able to click on a button and the data is transferred to a User Preset. Here is what I have:

The radio button selector shows and hides the controls for its specific preset nicely (probably because Niklas wrote the code
 But then, it all goes to hell. Can anyone help? Thanks.

Simplifying the problem:

    Set_UP1 = 537
    preset_value = rig[c4d.ID_USERDATA, 13]

    Classic_Beer_MASTER_Coalesce = rig[c4d.ID_USERDATA, 196]
    Classic_Beer_Coalesce_Amount = rig[c4d.ID_USERDATA, 197]

#User Preset 1
    UP1_MASTER_Coalesce = rig[c4d.ID_USERDATA, 507]
    UP1_Coalesce_Amount = rig[c4d.ID_USERDATA, 508]

if rig[c4d.ID_USERDATA, Set_UP1]:
        rig[c4d.ID_USERDATA, Set_UP1] = 0 #resets User Preset 1 button
        
        if preset_value == 0:
            print (preset_value)
            UP1_MASTER_Coalesce = Classic_Beer_MASTER_Coalesce
            UP1_Coalesce_Amount = 3

The Set_UP1 switch resets itself but I can't get the UP1 values to change. Any help? Thanks.

If your other code is correct. One, or possibly both, of these should fix the updating problem.
Try the SendCoreMessage() first.

op.SetUserDataContainer(descId, container)

c4d.SendCoreMessage(c4d.COREMSG_CINEMA, c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))

Neither of these work. Do you have any other ideas? I get no errors when I compile and nothing untoward is showing up in the console.

It looks like there is a problem defining user data as a variable.

Classic_Beer_Coalesce_Amount = rig[c4d.ID_USERDATA, 197]
UP1_Coalesce_Amount = rig[c4d.ID_USERDATA, 508]

C4D doesn't like this for some reason.

UP1_Coalesce_Amount = Classic_Beer_Coalesce_Amount
doesn't work but
rig[c4d.ID_USERDATA, 508] = rig[c4d.ID_USERDATA, 197]
does work. Any ideas?

It's just how python work.

For exemple

Classic_Beer_Coalesce_Amount = rig[c4d.ID_USERDATA, 197] 

the variable class_beer_coalesce_amount is egal to the value of rig[user_id]. so we can simpify as class_beer_coalesce_amount = 10 (I take 10 just as an exemple)

So by doing

UP1_Coalesce_Amount = Classic_Beer_Coalesce_Amount

You tell my first variable who store a value of 10 for exemple is now egal to my second variable who is egal to 20. But that only change variable value not the user id.

In you second exemple

rig[c4d.ID_USERDATA, 508] = rig[c4d.ID_USERDATA, 197]

For a better understanding is similar to

bc = rig.GetDataInstance()
bc.SetData(508, bc.GetData(197))

A good read https://jeffknupp.com/blog/2012/11/13/is-python-callbyvalue-or-callbyreference-neither/

Hope it's help you

Btw in future please use [ code] and [ /code] for posting code in the forum

If you want a switch here is an exemple with container and another one which is more efficient (since we dont have to iterate the list)

import c4d

    list_ud = obj.GetUserDataContainer()
    buffer_first = None

        obj[c4d.ID_USERDATA, first] = obj[c4d.ID_USERDATA, second]
        obj[c4d.ID_USERDATA, second] = buffer_first
        c4d.EventAdd()
    except:
        print "error can't switch"
  
def main() :
