Hi:

@PATPAT
First of all, the point movement algorithm of attitude deformation label is not complicated.

I've seen in some tutorials that you can add some data to a port with unconventional operations, but I forgot . So, I use Python nodes.

The data control label object weight value for the input port, so you need to add a user data of type link to the Python node.

Python is a dynamic language, and data types cannot be determined before compilation. There is no conditional right or wrong judgment in my code, so please add them by yourself.

import c4d

def main():

    obj = op[c4d.ID_USERDATA,1]

    Tags = obj.GetTags()
    
    Pose = [tag for tag in Tags if tag.GetRealType() == 1024237]

    #[4000,1101] is the ID of the strength value.  
 
    Pose[0][4000,1101] = Input1

    global Output1
    Output1 = Pose[0][4000,1101]

Hi:

After a trial run, the script was tested successfully. By setting the name suffix of Python Tag, the problem of repeated running of Tag can be solved.

Taking c4d.DIRTYFLAGS_SELECT as an example, if the point, line, and surface selections change, it will execute, otherwise it won't.

The Python script code is as follows:

import c4d
#e-mail: [email protected]

def main():
       
    Name = op.GetName()

    Objects = op.GetObject()
    Changed = Objects.GetDirty(c4d.DIRTYFLAGS_SELECT)

    Text = ["xit" + str(Changed)[-1]]
    
    if str(Name).count(Text[0][:-1]) != 0 :
        
        if str(Name).find(Text[0][:-1]) != str(Name).rfind(Text[0][:-1]) :
            
            if str(Name)[str(Name).rfind(Text[0][:-1]):] == Text[0] :
            
                if str(Name).find(Text[0][:-1]) <= 0:
                    
                    #Do not execute, exit the program.
                    print ("Does not perform.")
                    op.SetName(str(Text[0]))
                    
                    return
                
                else:
                    #Do not execute, exit the program.
                    op.SetName(str(Name)[:str(Name).find(Text[0][:-1])] + str(Text[0]))
                    print ("Does not perform.")
                    
                    return
                    
            else:
                if str(Name).find(Text[0][:-1]) <= 0:
                    
                    op.SetName(str(Text[0]))
                    print ("Perform.")
                    
                else:
                    
                    op.SetName(str(Name)[:str(Name).find(Text[0][:-1])] + str(Text[0]))
                    print ("Perform.")

        else:
            
            if str(Name)[str(Name).rfind(Text[0][:-1]):] == Text[0] :
                #Do not execute, exit the program.
            
                print ("Does not perform.")
                return

            else:

                op.SetName(str(Name)[:str(Name).find(Text[0][:-1])] + str(Text[0]))
                print ("Perform.")

    else:
        print ("Perform.")
        op.SetName(str(Name) + str(Text[0]))
    


    print ("pass")
    #The next thing to execute.

HI:

I recently doing point cloud reconstruction, and it's really not a difficult problem. So the first thing you have to do is figure out 2 points and the center of the circle, so there are 3 points.Then figure out the length of each side of the triangle surrounded by 3 points, and finally figure out the Angle between 2 points and the center of the circle.You plug in the arc length formula and you get the arc length between 2 points.

@kbar Thank you very much for your great work, because C++ development documentation has long lacked user education, and .XDL64 files cannot be generated smoothly even for novices who have the source files.You are really great to replace the SDK-team to complete the user education.

Before you posted the video, many people posted C++ development videos for C4D, but after version R19, the API interface parameters changed, and these videos lost their user education significance.Thank you for your contribution to making more people learn how to generate .XDL64 files. This is the first and most important first step.

@ferdinand Generating the .XDL64 file is the most important first step, but in the C++ development documentation, the Project Tool chapter is very professional and prevents novices from properly generating the .XDL64 file.

Suggest additional development steps, such as 1,2,3,.....
Such as:

    1:  Download the Project Tool.

    2:  Create a new .TXT file and write it to  ......\cinema4d_r23_project_tool_314356_win-macos\kernel_app_64bit.exe g_updateproject=......

    3:  .TXT file format changed to.bat.

    4:  ...

    5:  ...

   ......
