RE: This is a limitation you also have with the visual selector

Not really. You can multiple select hotspots and/or controllers in the visual selector.

Anyhow, thanks for the response. I guess there is no way around this.

@m_magalhaes

Thanks for the response, especially for the visual selector being old, as currently I find it buggy.
I check the interaction tag example files here:
https://help.maxon.net/r21/us/index.html#TINTERACTION

The main limitation I have found of it is I can only select one control at a time.
I can't drag and select controls like that of visual selector tag. Correct me if I'm wrong.

Hi,

Is there a way to iterator over the view/hotspots of the visual selector tag?
According to this thread, it is not possible. But perhaps, there were updates?

When you move the visual selector to another document, the link field will be lost. My use-case is to automate "inputting" the link field to every hotspots. Something like this:

for hotspot in hotposts:
    hotspot_name = hotspot.GetName()
    hotspot_obj = doc.SearchObject(hotspot_name) 
    hotspot.SetLink(hotspot_obj)

Regards,
Ben

Thanks for the response and the website reference.
I was able to work the code with the following revisions:

    def CoreMessage(self, id, bc):
        if id == 1234:

            P1MSG_UN = bc.GetVoid(c4d.BFM_CORE_PAR1)
            pythonapi.PyCObject_AsVoidPtr.restype = c_int
            pythonapi.PyCObject_AsVoidPtr.argtypes = [py_object]
            P1MSG_EN = pythonapi.PyCObject_AsVoidPtr(P1MSG_UN)

            # check message and act
            if (P1MSG_EN == 1):
                c4d.documents.GetActiveDocument().InsertObject(c4d.BaseObject(c4d.Ocube))
            elif (P1MSG_EN == 2):
                c4d.documents.GetActiveDocument().InsertObject(c4d.BaseObject(c4d.Osphere))

Thanks again. Will close this thread now.

Hi @r_gigante

Thanks for the response. There is an value error. I tried to solve it but the Cthing is still over my head :(
It's on line P1MSG_EN1 = pythonapi.PyCapsule_GetPointer(P1MSG_UN1, None)
with the error of ValueError: PyCapsule_GetPointer called with invalid PyCapsule object

Just wondering, why do we need to convert the data into C then back into Python ?

@r_gigante @zipit

Thanks for the response. Yea, I guess the connection was never made since the socket creation was made after mainloop

I tried the tkinter code provided by @r_gigante.
It works, the problem is it only works once. So after clicking next buttons, primitives are not created.
You can see it here:
https://www.dropbox.com/s/m2mpk2ctjkizgfc/c4d308_python_socket02.mp4?dl=0

I can see that the tkinter button works (i.e. prints out the "cube", "plane" etc on every click).
I guess the problem is the c4d plug-in receives it only once.
Is there a way to have the SpecialEventAdd() and CoreMessage run every time and not only once?

Hi @m_magalhaes

Ah gotcha. I guess I can't change the deformer's priority.
Anyhow. Thanks for the confirmation.

@r_gigante

Thanks for the response. I added c4d.SpecialEventAdd() and the CoreMessage on the GeDialog().
I expect when I click the tkinter button to print "Hey I am listening!" but I unfortunately get nothing.

Here is the revised code:

Hi,

I'm trying to connect C4D with Tkinter (External Application) through sockets (first time using it).
You can see an illustration of the problem here:
https://www.dropbox.com/s/vz1ixu3jozeujum/c4d308_python_socket.mp4?dl=0

I expect that a Cube is made when I press the Cube button, but as you can see nothing happens.
Interestingly, the Tkinter doesn't error out so I guess there is some connection that was made.

Here is the code so far(Tkinter):

from tkinter import *
import socket

window = Tk()
data = bytes('', "utf-8")
def send_msg(msg):
    data = bytes(msg, "utf-8")

b1 = Button (window, text="Cube", command=send_msg("cube"))
b1.grid(row=0, column=0)

b1 = Button (window, text="Sphere", command=send_msg("sphere"))
b1.grid(row=1, column=0)

b1 = Button (window, text="Plane", command=send_msg("plane"))
b1.grid(row=2, column=0)

window.mainloop()

host, port = '127.0.0.1', 12121 

socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.connect((host, port))

while True:
    socket.sendall(data)

Here is the .pyp file as plugin for C4D.

import c4d
import socket
from c4d.threading import C4DThread

thread_ = None
host, port = '127.0.0.1', 12121 

pluginID = 131313
pluginIDCommandData = 141414


def create_primitive(primitive_type):
    if primitive_type == 'cube':
        doc.InsertObject(c4d.BaseObject(c4d.Ocube))
    if primitive_type == 'sphere':
        doc.InsertObject(c4d.BaseObject(c4d.Osphere))
    if primitive_type == 'plane':
        doc.InsertObject(c4d.BaseObject(c4d.Oplane))

    c4d.EventAdd()

P.S. Some of the lines for .pyp was copied from the megascans plug-in. If you want a reference of it, you can check it here:

@m_magalhaes
Ah gotcha. I guess there is no way around this, yet.

Thanks for the confirmation.
