That works find ! Thank you so much

Hello @Cairyn,
thank you a lot for this answer. I try this quikly but now I have a better understanding of the Desclevels concept !

This is what the code looks like now :

import c4d
from c4d import gui


#Création d'une piste pour chaque donnée utilisateur
def AddAnimationTrack(op):

    LED = c4d.CTrack(c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER),
                    c4d.DescLevel(c4d.ID_USERDATA,3,c4d.DTYPE_LONG)))
    op.InsertTrackSorted(LED)

    return True
# Main function
def main():
    AddAnimationTrack(op)

# Execute main()
if __name__=='__main__':
    main()

@cairyn said in Insert User Data Track in Python:

c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER),
c4d.DescLevel(userdata_entry,c4d.DTYPE_LONG))

Hello ! Thank you for replying !

I've put your code but get a error :
"Traceback (most recent call last):
File "scriptmanager", line 19, in <module>
File "scriptmanager", line 15, in main
File "scriptmanager", line 9, in AddAnimationTrack
NameError: global name 'userdata_entry' is not defined"

Maybe I didn't get what I should do with "userdata_entry"

Hello,
I would like to add track (timeline) for each user data I have set on a object .
Here is the code I tried, but I don't know why it's not working

Here is the code I wrote :

import c4d
from c4d import gui


#Création d'une piste pour chaque donnée utilisateur
def AddAnimationTrack(op):
        
    LED = c4d.CTrack(op,c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA,1,c4d.DTYPE_GROUP),c4d.DescLevel(c4d.ID_USERDATA,2,c4d.DTYPE_GROUP),c4d.DescLevel(c4d.ID_USERDATA,3,c4d.DTYPE_REAL)))
    op.InsertTrackSorted(LED)

    return True
# Main function
def main():
    AddAnimationTrack(op)

# Execute main()
if __name__=='__main__':
    main()

I work on R21.
You can see the scene here : ADD_TRACK - 1.c4d

Thank you for helping

@Cairyn Thank you for your help ! That's it. I confused it all with the wrong word. Sory... Your answers help me very nicely

@ferdinand I apologize about going out of the guidelines. I understand this and will create new topic for that point

The multilines code works well.

Do you mean that there is no possibility to select clones ID to affect them with the Python Effector ?

TEST_CLONERS_2.c4d

@Cairyn thank you for answer

I can now add a line of code but how Can I add multiples lignes of code in the effector. I got some difficulties to manage this.

What I would like is to make a selection by ID of the cloner through the Python Effector.

In fact in this Effector I would like to create an id selection for the operator it will be linked to.

So I can add this code into the effector

Hello,
I want to insert a code (not written yet) into a python effector I created through a Python script. I figured out how to open the Editor but not how to change the code inside.

Can you help please ?
(running on R21)

import c4d
from c4d import gui
from c4d.modules import mograph as mo

def PythonEffector():
    PythonEffector = c4d.BaseList2D(1025800)
    #PythonEffector(c4d.OEPYTHON_OPENEDITOR) >> CHANGE THAT CODE WITH SOMETHING ELSE
    doc.InsertObject(PythonEffector)
    c4d.EventAdd()

# Main function
def main():
    PythonEffector()
    


# Execute main()
if __name__=='__main__':
    main()

Thank you @bentraje and @ferdinand !

You make the deal of the EffectorList function much clearer ! It works well now

Hello,
I'm very new on python and I would like to know how to link the "pyhton effector" I create in this exemple to the cloner. I tried to use the InsertObject function but it seems that it's not working. TEST_CLONERS_1.c4d

I run on R21

Can you help ?

@zipit Hello back !
I tried to use the code your wrote and actualy, linking ports is working but creating ports by iterating into them and pick them by order's number doesn't seems to work.

I had that kind of thing in the code I've sent (line 39, 40). But it doesn't work. I should have the first output of the "Mograph data" node (called "Données").

Can you explain my mistake ?

About your code I still can't create ports on nodes... I tried to create all out and in ports of the nodes but nothing appened. I've commented your lines where you link the ports to focus on ports creation... Can you help me with this please ?

    # Ports have two ways to be indexed: By an index (0, 1, 2, ...)

    # we will ignore this for now. In Python we have to iterate over all ports
    # to get a port by its main id.

@zipit Thank you !

Your answer is quite clear !
I try to use this as soon as possible and let you know about the result

@zipit Thank you for quick answer !

That's weird 'cause a got this result on R21.207 :

Ports are created as expected...

But I just wonder how I can get the Global matrix and Local matrix ports ID... Still a mistery for me about how I can use any peace of code to get that

Hello,
I'm new in python's world. I would like to know what peace of code I can wrhite to get any ID of nodes and nodes' ports.

I'm running C4D R21 under MAC OS.

In that case I'm trying to generate global and local matrice ports but it would be nice if I can use this to find any ports I need.
Here is a peace of code I've done, that generates some nodes and ports.

I've done some research but I'm a bit confused about how to do it.

Can you help me on that point ?
Thank you

ohh... forgot that !

I'm Working on

• MAC OS 10.14.6
• Cinema 4D R21

Hello Zipit,
Thank you a lot for posting advices and answering quit. Your explanations are very precise and clear. Coding might be difficult but offers incredible possibilities. [link text]PYTHON_FIELD_SCRIPT V 0.1.c4d

Please, can you tell me how can I add tags to my post ?

About my project, I think you have a good idea of what I want to do but I'll try to be as precise as possible this time. I attached the scene, it should be easier to understand what I want to do then.

I have 5 "Families" (groups) of clones, determined by the Sphere Fields called "FAMILY_X". Needed for my project evolution.

1. I want them to go from their starting position and morph to FIG_01 which is a grid during a determined time (set into User Data (ex "Transition_time (sec)") of the Python Force Field)

2. For ich family, I want to start the mouvement at a different time (that can be set in User Data (ex "Start_Time // Family_0") of the Python Force Field).

If it is possible with Python Force Field, what code should work to do that ?

If not, what is the best solution to do that ? Python Tag ? Python Script ?

Thank you !

... I forget one important information : This is a Python Force Field

Hello guys,
I started learning Python few days ago and I definitly need help from the pyhton dev community !

I wish to insert a "delay time" that can be inputed by the user for each loop I created. How can I do that ?

Here is my code :

import c4d
import math
import time
import threading
from c4d.modules import mograph as mo
#Welcome to the world of Python Fields

def Sample(op, inputs, outputs, info):
    """Calculate the output values for the specified set
    of input points. Allocations should be avoided in Sample
    to maximize performance.
    Return false on error to cancel sampling.
    NOTE: Sample function is mandatory, PythonField cannot
    function without it.

    Keyword arguments:
    BaseObject -- the python field.
    FieldInput -- the points to sample.
    FieldOutput -- the sampling output arrays (pre-allocated).
    FieldInfo -- the sampling informations.
    """

    NbObjFamily = 5
    flight_time = 5
    delay = 5*(doc.GetTime().Get())
    
    # Wave "0"
    for i in range(0, inputs._blockCount, NbObjFamily):
        value = (doc.GetTime().Get())
        offsetValue = value / flight_time
        outputs.SetValue(i, offsetValue)

    # Wave "1"
    for i in range(1, inputs._blockCount, NbObjFamily):
        value = (doc.GetTime().Get())
        offsetValue = (value + 0.0) / flight_time
        outputs.SetValue(i, offsetValue)

    # Wave "2"
    for i in range(2, inputs._blockCount, NbObjFamily):
        value = (doc.GetTime().Get())
        offsetValue = (value + 0.0) / flight_time
        outputs.SetValue(i, offsetValue)

    # Wave "3"
    for i in range(3, inputs._blockCount, NbObjFamily):
        value = (doc.GetTime().Get())
        offsetValue = (value + 0.0) / flight_time
        outputs.SetValue(i, offsetValue)

    # Wave "4"
    for i in range(4, inputs._blockCount, NbObjFamily):
        value = (doc.GetTime().Get())
        offsetValue = (value + 0.0) / flight_time
        outputs.SetValue(i, offsetValue)

    # Return false to cancel further sampling.
    return True

Any Idea ?

Thank you
