Here's my first post here. Seems there's a great community here!
I'm currently working on an OSC plugin for C4D which allows you to use c4d as a timelining tool for creative coding purposes. So far it works great, but i'm a little slow at picking up the Python API so far....
Enumerate all User Data parameters for a c4d.BaseObject, and for each get the name and the current value.
I have test parameters:
* brightness (real)
* resolution (long)
* name with spaces (%)
* subgroup (group)
* testSubGroupMember (%)
And if I do:
[((2, 19, 0), <c4d.BaseContainer object at 0x118e17bc8>), ((1, 15, 0), <c4d.BaseContainer object at 0x118e0eae8>), ((4, 19, 0), <c4d.BaseContainer object at 0x118f4e340>), ((5, 1, 0), <c4d.BaseContainer object at 0x118f4e308>), ((6, 19, 0), <c4d.BaseContainer object at 0x118f4e030>)]
so i'm able to get the name of each parameter by doing like:
userData = obj.GetUserDataContainer()
[returns] : brightness
then i get the name of the 0th parameter, great! so now all I need is the value...
To get each value, I can use
print obj[c4d.ID_USERDATA, index ]
and i can see the correct index from
[returns] ( 2 , 19, 0)
which is a DescID, and is useful, because it means I can do
print obj[c4d.ID_USERDATA, 2 ]
[returns] : 0.083
Which is the correct value.
So far, wonderful!
So now I have to get that index of 2 out of the DescID, so I would do something like:
[returns] <c4d.DescLevel object at 0x117c241f8>
ok, so that wasn't what I wanted, we get a DescLevel instead of a DescId,
so let's see if we can get the 2 out of that DescLevel....
print obj[c4d.ID_USERDATA, userData.id
ok so how do I get the 2 out? I can't see any other accessors which are useful here
currently the only option i can see is
idString = obj[c4d.ID_USERDATA, userData.__str__()
and then performing string operations to get the 2 out of "(2, 19, 0)"
but that seems crazy. which is where the question come in :).
how to get the 2 out of the DescID?
To note, I'm doing this within the context for an plugins.ObjectData and looking at the child objects

welcome to the Forum.
Just use the DescID.

If you still need the actual user-data index, it is stored at the second position. The first is c4d.ID_USERDATA (700)
> index = desc_id.id
(the text representation of the DescID is not really helpful.)
Btw, use str() instead of .__str__().

that totally makes sense. not sure why i couldn't see that before
is there a page anywhere with all the c4d constants btw?
i'm often finding constants that i can't identify within many different ranges
so i presume str(obj) is more standard than obj.__str__()
i'm still new in python
I managed to get the exact result that I wanted using:
def GetFirstArg(descID) :
text = descID.__str__()
but this seems much more sensible now.
