Hi Ferdinand, thanks for the reply and I totally understand the out of scope of support part!
Thanks!

Regarding the freeze, my system specs are:
15", Apple M2 2023
macOS 13.5.2 (22G91)
C4D 2024.4.0
Just trying to import ctypes freezes C4D instantly.

Regarding the SpecialEventAdd() case:
I essentially want to act after a threaded operation is finished. So the last line of my threaded function calls:
c4d.SpecialEventAdd(ids.PLUGIN_ID_EXPORT)

To distinguish between different types of export I thought I could use the p1 (x) e.g.: c4d.SpecialEventAdd(ids.PLUGIN_ID_EXPORT, x)

However when using this inside my dialog, I'm not sure how to receive the different p1 or p2 integers inside the CoreMessage():

def CoreMessage(self, id, msg):
    if id == ids.PLUGIN_ID_EXPORT:
        logger.info("PLUGIN_ID_EXPORT Message")
        if msg == x:
            logger.info("Finished thread Message")
            do_some_logic_here()
            return True
    return False

So what I'm asking is: I think different int are sufficient enough for my case, but I'm not sure how to receive those correctly within the CoreMessage or Message of a commanddata plugin.

Thanks again,
Lasse

Hi @m_adam,
yes, that is correct. However, I experience a freeze everytime I do:
from ctypes import pythonapi
which I need either way.

Hi there,
I've just noticed something slightly odd.. While doing the following:

from ctypes import pythonapi, c_void_p, py_object

either in a script or plugin, Cinema4D freezes instantly.

I came across this issue, because I wanted to implement a way to react to my SpecialEventAdd() messages. I stumbled upon this example:

https://github.com/Rokoko/rokoko-studio-live-cinema4d/blob/ba4bd7a3c7eb814b13296a7ef564b0024efb0c4d/rokoko_utils.py#L37

Is this still the way to go in 2024 to receive the SpecialEventAdd() p1 or p2 messages? And why is this instantly freezing C4D on my MacBook Air M2?

Cheers,
Lasse

AFK currently, but I think you can open the "Script Log..." from the Extensions Menu to check the ID's right!?

Thanks, for the clarification. @ferdinand

With "Customize Commands..." we are able to "restrict" certain commands to certain "managers" or "menus". I'm wondering if it's possible to detect these managers within a cmd-data-plugin while the mouse is hovering over a certain area.

Imagine a popup filled with different content based on the currently hovered manager i.e. object-manager, material-manager, take-manager...!

Is there a way to detect the underlying context of the mouse via python..?

I could make a recursive iteration to go through all of the document's objects but that would slow it down significantly...

Yeah, but that's basically the way to go... Not sure if the following yields faster results:

def get_next_element(op):
    if not op:
        return
    if op.GetDown():
        return op.GetDown()
    while (not op.GetNext()) and op.GetUp():
        op = op.GetUp()
    return op.GetNext()

def main():
    obj = doc.GetFirstObject()
        
    while obj:
        # act on obj
        print(obj.GetName())

        obj = get_next_element(obj)

Always wondered what approach would yield faster results...

Feel free to do some testing, would love to hear your results.

My guess is that iterating over with enumerate BaseDocument.GetObjects(self) would be efficient enough..?

For example:

all_objs = doc.GetObjects()
for i, obj in enumerate(all_objs):
    # Distance can be whatever float or integer
    your_dist = i * 27
    pos = c4d.Vector(your_dist, 0, 0) 
    obj.SetAbsPos(pos)

Hi there,

I'm currently having a japanese customer for my AEC4D-PRO plugin that complains, that the plugin isn't behaving correctly in R23. In older C4D-Versions the plugin seems to behave correctly.

At first, I thought the problem lies within string encoding. However at further testing, it works for the customer if he changes his "Interface Language" to English. So it's not the typical string encoding when transferring Objects between the two programs.

I'm actually a bit lost, how this language setup is intertwined with the plugin itself. Sadly, I don't have the time to test the Japanese Language myself, so I thought if anyone has experienced these kind of issues before he or she might jump in and help.

If you want to test it yourself, feel free to download the 14-day trial here:

Thanks so much.

I guess I found a workaround... I cannot show the whole code involved but something along those lines:

I have a Treeview that stores an absolute path abs_path of different documents... Now, I just check if one of these filepaths is in my open documents paths via: get_all_docs_paths()

def get_all_docs_paths():

    all_docs_paths = []

    first = c4d.documents.GetFirstDocument()
    while first:
        folder = first.GetDocumentPath()
        abs_path = os.path.join(folder, first.GetDocumentName())
        all_docs_paths.append(abs_path)
        first = first.GetNext()
    
    return all_docs_paths

If yes, the document is open, if not it is closed.

Cheers,
Lasse

Thanks, @mp5gosu ...!

@zipit said in Detect closing of Document:

The easiest way would be to use some kind of plugin node for that. I currently do not see a way to do this in a GeDialog, but I might be wrong. We will discuss that tomorrow in the SDK Team, to see if the others know a clever way to do that. Just wanted to make sure that you do not run down a rabbit hole with no exit

Hehe, yeah that's exactly what I thought when looking at MSG_DOCUMENTINFO . Thanks for the quick answer, Ferdinand. Looking forward to your thoughts and ideas...

Cheers,
Lasse

I basically want to react in my GeDialog if my active document has been closed.
I'm currently looking at MSG_DOCUMENTINFO but there's no flag for a closed document... one other idea would be to listen to a CallCommand for example via c4d.MSG_DESCRIPTION_COMMAND?

What would be the best way to approach this..?

Thanks,
Lasse

@mp5gosu Damn. That's really not the answer I wanted to hear, Robert!

Hey everyone,

I'm currently developing a treeview-plugin for all my scripts/presets etc.. I was wondering if it is possible to drag and drop items of said treeview directly to my layout.

I'm currently thinking along those lines:

In my declared ListItem (obj) I have a property of Instance which can hold the reference to the CommandPlugin for each script.

    @property
    def Instance(self):
        # of course this just a placeholder (but a valid one...)
        return c4d.plugins.FindPlugin(600000174)

In the GenerateDragArray I will create an Array with my said Instance/Reference, also I've tried setting different flags for GetDragType to c4d.DRAGTYPE_COMMAND etc....

    def GenerateDragArray(self, root, userdata, obj):
        if obj.IsSelected:
            return [obj.Instance]
        return None

    def GetDragType(self, root, userdata, obj):
        return c4d.DRAGTYPE_COMMAND

    def SetDragObject(self, root, userdata, obj):
        return obj.Instance

...but, sadly it's NOT working as I would expect...

Is this possible with python in general, or a limitation? What am I missing?

Thanks,
Lasse

Had one aswell....

a rather old one... ...haha.

yep, back online... here in hamburg.

Hi there,

https://developers.maxon.net/ appears to be offline? Is this just a short outage..?

@zipit said in Rename object by filename:

PS: @lasselauch I know that you meant this in a light-hearted manner, but "let-me-google-that-for-you" can be misconstrued. People have different information needs and things that seem trivial or obvious to you, are not for them. Programming can be a confusing topic and we would like this to be a welcoming place for everyone and subsequently stay away from all "RTFM"-notions.

Yep, definitely meant in a light-hearted manner!!!
You're totally right.. that's why I provided the correct answer.

Cheers,
Lasse

Of course there are a lot of ways to spin this, but I guess in most cases this should be enough:

# import os
import c4d

def main():
    if not doc:
        return
    docname = doc.GetDocumentName()

    # docname, _ = os.path.splitext(docname)
    docname = docname.replace('.c4d', '')
    
    null = op.GetMain()
    if not null:
        return

    null.SetName(docname)

Download: null-docname.c4d
