Thanks for help @a_block , @m_adam . I think the answer to this question is that we can't control the open/close of the group

@m_adam Still can't succeed
In the same Attribute Manager window, for multiple objects with the same UserData, it seems that it is impossible to control the opening or closing of a group alone. If I open (or close) the group of one object, the group corresponding to other objects will also be opened (or closed)

@m_adam Setup succeeded, but the group GUI did not unfold

use python

c4d Use Default Open ,group unfold

c4d not Use Default Open ,but group not fold

@m_adam Thanks for help!

Hi,
in c4d manager UserData dialog can set group Default Open,but i dont how to set fold/unfold in python .
my code:

bc = c4d.GetCustomDataTypeDefault(c4d.DTYPE_GROUP)
bc[c4d.DESC_NAME] = "group_test"
group_did = obj.AddUserData(bc)

bc = c4d.GetCustomDataTypeDefault(c4d.DTYPE_STRING)
bc[c4d.DESC_NAME] = "test"
bc[c4d.DESC_PARENTGROUP] = group_did
did = obj.AddUserData(bc)

Thanks for any help!

Hi.
i want set String UserData interface to multi_line,but in DESC dont find parameter to set.
this is my code:

bc = c4d.GetCustomDataTypeDefault(c4d.DTYPE_STRING)
bc[c4d.DESC_NAME] = "test"
did = obj.AddUserData(bc)

Thanks for any help!

@ferdinand Thanks your reply!

Hi @Cairyn
Thanks for your help, I use method 2 to achieve my goal.
This is a plug-in to mirror a selection of the same / different objects. Thank you for your help again,gif_2 show its work
gif_2

Hi @cairyn ,thanks for your help!
I have made some progress, but there are still some problems!

the image_1 show want wo select 2 edges.
image_1:

Through your reply, it seems that I have got 2 directions to solve my problem. I will show it in the following image_2.
image_2:

use method 2 ,can select the edge show on gif_1.
gif_1:

method 2 code:

import c4d
from c4d import gui


def main():
    if op == None:
        return
    if op.GetType() != c4d.Opolygon:
        return
    
    bs = op.GetEdgeS()
    bs.DeselectAll()
    poly_cnt = op.GetPolygonCount()
    
    sel = bs.GetAll(poly_cnt * 4)
    
    
    edge_list = [(0,1),(0,4)]
    

    for poly_id in range(poly_cnt):
        poly = op.GetPolygon(poly_id)
        for edge in edge_list:
            p1,p2 = edge
            
            edge_index = poly.FindEdge(p1,p2)
            if edge_index != c4d.NOTOK:
                sel[poly_id * 4  + edge_index] = 1
    
    bs.SetAll(sel)
        
    
    c4d.EventAdd()

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

Hi,
I know how to select a point / face, but I still don't know how to select an edge. Does each edge have a unique ID? For example, two quadrilateral faces have seven edges. If I choose an edge, I can know that its ID is 6.
I have a picture below. I have marked the edges I want to choose, but I don't know what to do. Can have a simple code demonstration?
Thanks for any help!

@ferdinand I also use ScreenToGif to make pictures！

@ferdinand Thank you for your detailed answer!
In my autoweight function, there is no error in the calculation result of the tangent, but when setting the CKey, there is a problem. It seems that there are too many parameters set, which causes the left and right time values of the key frame to be set according to the calculation results. Then an unknown change was made, causing the final value to not match the calculated value. Although I still don't know why those settings will cause the value to go wrong.

wrong code:

    key.SetInterpolation(curve,c4d.CINTERPOLATION_SPLINE)

    key.SetTimeLeft(curve,L_time_v)
    key.SetValueLeft(curve,TL_vector[1])
    key.SetTimeRight(curve, R_time_v)
    key.SetValueRight(curve, TR_vector[1])

    key[c4d.ID_CKEY_PRESET] = c4d.ID_CKEY_PRESET__CUSTOM
    key.ChangeNBit(c4d.NBIT_CKEY_AUTO, c4d.NBITCONTROL_CLEAR)
    key.ChangeNBit(c4d.NBIT_CKEY_BREAK, c4d.NBITCONTROL_SET)
    key.ChangeNBit(c4d.NBIT_CKEY_KEEPVISUALANGLE, c4d.NBITCONTROL_SET)

current code：

    key.SetInterpolation(curve,c4d.CINTERPOLATION_SPLINE)
    key.SetTimeLeft(curve,L_time_v)
    key.SetValueLeft(curve,TL_vector[1])
    key.SetTimeRight(curve, R_time_v)
    key.SetValueRight(curve, TR_vector[1])
    key.ChangeNBit(c4d.NBIT_CKEY_AUTO, c4d.NBITCONTROL_CLEAR)

Using the current code, the left and right time values of CKey, the calculated result matches the final result.
this is an print example:

    Calculate_RTime: 0.0301874202486 After_Set_Get_from_Key_RTime 0.03

gif also shows that it is working fine now.

@ferdinand Thanks for your help!
I have been looking for the source of the problem. After seeing your answer, I should have looked in the wrong direction (I always thought that SetTimeLeft() could not accurately transmit the value I calculated). Below I uploaded a GIF to show the problem I encountered more accurately.
1: I use Add key slider to dynamically add functions. It will call my autoweight function by default. It can be seen that in the process of dynamic addition, the error of RightTime == 0 of some key frames appears
2: When I dynamically use EasyInOut slider to perform the smoothing process, it also calls the autoweight function, and it still does not correct the wrong situation
3: When I use c4d's default auto tangent classic for these key frames, then use EasyInOut again to perform the smoothing process, the autoweight function will work normally.
So I don’t know why this happens, because the above code is used to set the key in the autoweight function

It seems that can't see the gif in full,i upload a file ,can be download. easyinout2.gif

@aimidi said in SetTimeRight fail!:

SetTangents

Thanks for your help,but not find SetTangents() in python sdk

Hi, when the value I set is very small, such as BaseTime.get() is 0.001, by using SetTimeRight（）, but when I access this value again by script, the result is BaseTime.get() is 0. but SetTimeLeft（） can Successfully set, such as BaseTime.get() is -0.001 !
Thanks for any help!

        key.SetInterpolation(curve,c4d.CINTERPOLATION_SPLINE)
        

        key.SetTimeLeft(curve,L_time_v)
        key.SetValueLeft(curve,TL_vector[1])
        key.SetTimeRight(curve, R_time_v)
        key.SetValueRight(curve, TR_vector[1])

        key[c4d.ID_CKEY_PRESET] = c4d.ID_CKEY_PRESET__CUSTOM
        key.ChangeNBit(c4d.NBIT_CKEY_AUTO, c4d.NBITCONTROL_CLEAR)
        key.ChangeNBit(c4d.NBIT_CKEY_BREAK, c4d.NBITCONTROL_SET)

@ferdinand Thanks for your detailed reply!
" 2.The timeline (and as a matter of fact also the world coordinate system) has no implied unit. There is no direct translation as 1px == 1cm as both the horizontal axis and vertical axis depend on the zoom level." solved my question！

Hi,
I want to use my method to calculate the tangent and weight of the animation curve.

But I ran into a problem. I can’t know how the vector base of the coordinate system of the TimeLine panel is defined. In the 3D coordinate system, x=1 cm, y=1cm, z=1cm, but in the TimeLine panel, x= 1Frame ?1 second, y =1 cm?1%? or 1 Degree.

Thanks for any help!

@ferdinand Thanks,great!

Hi,
in picture object Position gui unit is real, Rotation gui unit is Degree , User data gui unit is Percent. how to know gui unit? and how to directly obtain the value displayed on the panel(Data = 0.1745, want to directly get 17.453)?

Thanks for any help!

@m_adam Great, thank you！
