@ferdinand Thank you for letting me know that switching between modes is irreversible! My initial thought was that when I generate an empty object in edit mode, if I undo the action, I could return to edit mode. Thanks again for your explanation

Hi @ferdinand
Thanks for your help! Apologies for not providing code earlier, and also for the confusion with the PySide GIF – it was just an analogy to explain the batch triggering concept I was trying to achieve in C4D.

I'm happy to report that I've successfully resolved the issue with the global signal for user data buttons. Your guidance on the message system was very useful~

Cheers

@ferdinand Thansk!

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'

Just like this, I can manually click each object's user data button to make it do its work. Then I also have a button that can trigger the content inside each object's Python tag in a batch~

Thanks @ferdinand
I've found that c4d.CallButton doesn't seem to simulate clicks on buttons created via custom user data. Or, when I click a user data button, can it send a global signal? I don't quite understand the Message function of the Python tag. If I can send a global signal, then the Message functions inside all objects with Python tags could receive the signal, allowing for unified batch triggering. This seems more elegant than simulating clicks on buttons of different objects to trigger them.

Hello everyone, I want to simulate clicking buttons on other objects through a custom button. Is this possible?
Thank you!

@i_mazlov said in Frozen Matrix different:

象，并且没有其

I found that it's very similar to the offsetParentMatrix attribute introduced in Maya 2020.：）

@ferdinand My English isn't very good, sorry about that. What I mean is that when I am in edit mode and select points/edges/polygons, create a null object, and then switch back to object mode, if I want to undo, it would be more 'user-friendly' if I could return to the previous edit mode instead of object mode
It's good to know that calling doc.SetMode(c4d.Mmodel) is non-undoable; I struggled with this for a while

Hello all, my script needs to work in point, edge, and polygon modes (edit modes). At the end of the script, I will switch it back to model mode, but I'm not sure how to undo the mode switching. When I run the code in point mode, I can't return to point mode when undoing

import c4d

def main():
    sel = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_CHILDREN)
    if not sel or not doc.IsEditMode(): return # edit mode

    doc.StartUndo()
    for obj in sel:
        doc.SetSelection(obj, c4d.SELECTION_SUB)
        joint = c4d.BaseObject(c4d.Ojoint)
        doc.AddUndo( c4d.UNDOTYPE_NEWOBJ, joint)
        doc.InsertObject(joint, None, obj, True)
        doc.SetSelection(joint, c4d.SELECTION_ADD)
        ...

    doc.SetMode(c4d.Mmodel) # set model mode
    doc.EndUndo()
    c4d.EventAdd()

if __name__ == '__main__':
    main()
