Hi,

here is some code i used for create pypv

def call_c4dpy(C4D_PATH, cmd):
    # 需要把c4dpy.exe所在路径添加到环境变量
    # C4D_PATH = r"~\Maxon Cinema 4D R26"
    if C4D_PATH not in os.environ["PATH"]:
        os.environ["PATH"]+=f"{C4D_PATH};"

    # cmd 也可以是脚本路径 cmd = r"~\c4dtest script.py" 
    _cmd = f"c4dpy \"{cmd}\"" # 脚本路径必须是字符串
    subprocess.call(_cmd) # 调用并且可以实时看到结果 

def creat_pypv(C4D_PATH, plugin_path):
    # pyp 生成 pypv
    # c4dpy.exe g_encryptPypFile="G:\C4D JACK Plugins\G4Designer\G4Designer.pyp"
    cmd = f"c4dpy g_encryptPypFile=\"{plugin_path}\""
    call_c4dpy(C4D_PATH, cmd)

Hi,

https://developers.maxon.net/docs/py/2024_3_0/modules/c4d.utils/SplineHelp/index.html#SplineHelp.InitSpline
SplineHelp.InitSpline(self, op, up=Vector(0)) in the documentation raise an error,
TypeError: 'up' is an invalid keyword argument for this function in 2024,
'upvector' seems to be the correct keyword argument.

Hi,

I want to create a plane and spline and use the SplineWrap effector to wrap the plane around the spline and then return the cached polygon.

But the code doesn't return the correct result，
Did I write something wrong somewhere?

import c4d

def main():
    height = 300

    temp_doc = c4d.documents.BaseDocument()

    # spline
    spline = c4d.BaseObject(5186)
    temp_doc.InsertObject(spline)
    
    # plane
    plane = c4d.BaseObject(5168)
    temp_doc.InsertObject(plane)

    plane[c4d.PRIM_PLANE_WIDTH] = 1000
    plane[c4d.PRIM_PLANE_HEIGHT] = height
    plane[c4d.PRIM_AXIS] = 4  # +z
    plane[c4d.PRIM_PLANE_SUBW] = int(plane[c4d.PRIM_PLANE_WIDTH]/10)
    plane[c4d.PRIM_PLANE_SUBH] = 1

    spline_wrap = c4d.BaseObject(1019221)
    spline_wrap.InsertUnderLast(plane)
    spline_wrap[c4d.MGSPLINEWRAPDEFORMER_SPLINE] = spline
    spline_wrap[c4d.MGSPLINEWRAPDEFORMER_AXIS] = 1

    # poly
    #c4d.documents.InsertBaseDocument(temp_doc) # Enabling this line will give different results
    temp_doc.ExecutePasses(bt=None, animation=True, expressions=True, caches=True, flags=0)
    
    bc = c4d.BaseContainer()
    bc[c4d.MDATA_CURRENTSTATETOOBJECT_INHERITANCE] = True
    bc[c4d.MDATA_CURRENTSTATETOOBJECT_BUILDFLAGS] = c4d.BUILDFLAGS_INTERNALRENDERER
    res = c4d.utils.SendModelingCommand(c4d.MCOMMAND_CURRENTSTATETOOBJECT, 
                                        [plane],
                                        mode=c4d.MODELINGCOMMANDMODE_ALL, 
                                        bc=bc, 
                                        doc=temp_doc, 
                                        flags=c4d.MODELINGCOMMANDFLAGS_NONE
                                        )
                                        
    print(res)
    cache = res[0]
    doc.InsertObject(cache.GetClone(0))


if __name__ == '__main__':
    main()
    c4d.EventAdd()

Hi,
thanks for letting me know that.

Hi,
I am writing a ToolData plugin，'msg[c4d.BFM_INPUT_CHANNEL]' always returns 1 in MouseInput function, I would like to know how can i get mouse right button event?

def MouseInput(self, doc, data, bd, win, msg):
    # Retrieves which clicks is currently clicked
    print(msg[c4d.BFM_INPUT_CHANNEL])  # -> 1

Thanks~

I am using command-line to execute a C4D script through c4dpy.exe. I want to close c4dpy after the script execution completes. How can I do this?

def main():
    parser = argparse.ArgumentParser()
    parser.add_argument('--args', type=str, help='argument to be passed')

    args = parser.parse_args()
    if args.args:
        print(f'Received argument: {args.args}')      

    # quit c4d?
    c4d.CallCommand(12104)

In addition, I am rendering a octane scene in this script, but sometimes the rendering process keeps running and it is unclear whether it is a bug in c4dpy or if I am using c4dpy incorrectly.

import c4d 
import os

class RenderAgent:

    def __init__(self):
        self.progress = 0
        
    def render(self, doc, save_path=None, thread=None):
        self.progress = 0
        rd = doc.GetActiveRenderData()
        rd[c4d.RDATA_ALPHACHANNEL] = 1
        bmp = c4d.bitmaps.MultipassBitmap(int(rd[c4d.RDATA_XRES]), int(rd[c4d.RDATA_YRES]), c4d.COLORMODE_RGB)
        bmp.AddChannel(True, True)
        # Renders the document
        if thread:
            thread = thread.Get()
        
        if c4d.documents.RenderDocument(doc, rd.GetData(), bmp, c4d.RENDERFLAGS_EXTERNAL, thread, prog=self.PythonCallBack, wprog=self.PythonWriteCallBack) != c4d.RENDERRESULT_OK:
            #print("Failed to render the temporary document.")
            return False
        if save_path:
            bmp.Save(save_path, c4d.FILTER_PNG, data=None, savebits=c4d.SAVEBIT_ALPHA)
        return bmp

    def PythonCallBack(self, progress, progress_type):
        self.progress = float(int(progress*100))
        if self.progress>100:
            self.progress = 100
        print(self.progress)
        # !!
        # When i print self.progress  inside octane renderer scene (Actually, I am using a logging module. It can redirect the print output to an external log.txt file.)
        # it will still return 0 after it return 100 
        # It seems that the renderer has entered an infinite loop.

    def PythonWriteCallBack(self, mode, bmp, fn, mainImage, frame, renderTime, streamnum, streamname):
        ...

# call this in c4dpy
# simple code
RA = RenderAgent()
save_path = r"..."
RA.render(doc, save_path)

my log file looks like this:


LEVEL:1 - 2023-05-06 16:10:23

Dear Community,

I have been using c4d UserArea for a while and have always wanted to write a library to encapsulate UserArea for better usability by users. So I created this module called ualib .

The plugin ui in this following image is created using ualib.

ualib is a user interface framework based on the C4D GeUserArea module, which allows for the convenient creation of various UI controls that are typically difficult to create within C4D. It's a bit like PyQt, but simpler. You can create and replicate interfaces quickly and easily.

This is GitHub link. https://github.com/JACKADUX/c4d-ualib/wiki
Please feel free to download and use it. I will continue to optimize and improve this library. If you have any questions, please feel free to contact me or leave a comment.

Cheers,

Hi @ferdinand ，

First of all, I apologize for my poor explanation.

I ran into an unexplainable situation, but your example solved my problem nicely.
I couldn't get consecutive characters because I mistakenly called the self.GetInputState(c4d.BFM_INPUT_MOUSE, msg.GetInt32(c4d.BFM_INPUT_CHANNEL), msg) method and it would interrupt getting the original input.

now I have solved the problem. Thank you very much you guys are the best!
Cheers~

Hi,
I am using GeUserArea to create a text editor in python.
but when I use BFM_ INPUT_ ASC, it will only return one character!
How can i get full input of characters? (Here is the simplified code

def InputEvent(self, msg):
    # i entered 'test' 
    asc = msg[c4d.BFM_INPUT_ASC]
    print(asc)
    # >>> t
    # but i only get 't'

i want to input 'test' here

i write 'test' and pressed enter

it will only return 't' , but i want to get fully return of 'test' at once

@ferdinand hi, is that a bug or i did something wrong? (i used 'AddMultiLineEditText ' in your code )

JACK0319

hi thanks for quick reply ! I'm sorry I didn't explain my problem clearly. I'm not a native English speaker.
By ‘’refresh doc‘’, I mean to add a new doc.
After some tests, I found that the problem was caused by: self.AddMultiLineEditText(self.ID_MultiText, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, initw=0, inith=80, style=0)

I have creat a list of subdialogs inside scroll group, and subdialog have a function will open doc.when i do this command, the scroll group will also be randomly changed?
and i also can recive the message use:

def Message(self, msg, result):
        if msg.GetId() == c4d.BFM_SCROLLGROUP_SCROLLED :
            print("scroll group change when document refresh")
        return c4d.gui.GeDialog.Message(self, msg, result)

i think this is a bug because it not happen in r24, is there any solution in r26?
