ChangeNBit() Method Parameter Issue: c4d.AHIDE_FOR_HOST Not Recognized?

[kangddan]

I've identified an apparent invalid parameter error with GeListNode.ChangeNBit() in C4D 2024. Specifically, c4d.AHIDE_FOR_HOST throws an AttributeError, conflicting with its presence in the R20+ SDK documentation. Any insights on why this parameter isn't recognized?

import c4d

doc.StartUndo()
doc.AddUndo(c4d.UNDOTYPE_CHANGE, op)

op.ChangeNBit(c4d.AHIDE_FOR_HOST, c4d.NBITCONTROL_SET) # error

doc.EndUndo()
c4d.EventAdd()

error

Traceback (most recent call last):
  File "scriptmanager", line 6, in <module>
AttributeError: module 'c4d' has no attribute 'AHIDE_FOR_HOST'

Hey @kangddan,

Thank you for reaching out to us. The module attribute is NBIT_AHIDE_FOR_HOST. The line there in the docs might have been written when we still exposed symbols manually (and were a little bit inconsistent - these days symbols are exposed automatically) or always has been incorrect. But our documentation is still managed manually, something I probably should change, but that will also cost time.

When unsure, you can always search {c4d}\resource\modules\python\libs\python311\c4d\__init__.py, as this is where all the c4d symbols are defined. Or you just search {c4d}\resource\modules\python\libs\python311\ and with that the whole API. Last but not least, symbols are always just that - symbols - and you can also just use the raw value directly lifted from the C++ API frameworks (when something has not correctly been exposed for some reason). That would have been 95 in this case:

I have updated the Python docs for this member of NBIT to be named as c4d.NBIT_AHIDE_FOR_HOST.

Cheers,
Ferdinand
