Probably there is a better way but you can try this method

selectionTag = op.GetTag(5673)
c4d.CallButton(selectionTag , c4d.POLYGONSELECTIONTAG_COMMAND3)

I'm such an idiot Seems like the same code can be applied to user-defined descriptions.
SOLVED!

We all have to learn C++

I guess you want to create a node of the node.

Hello PluginCafe!

I'm trying to display object points via the tag plugin.
The code worked fine in older versions of C4D but it has no effect in the latest versions.
Am I doing anything wrong?

    def Draw(self, tag, op, bd, bh):

        bd.SetPen( c4d.Vector(1))
        bd.SetPointSize( 3 )
        bd.SetMatrix_Screen()
        bd.SetDepth(True)
        objMg = op.GetMg() #Get the world (global) matrix 

        ptList = op.GetCache().GetAllPoints()

        points = [objMg * p for p in ptList]  # Retrieves Global Coordinates
        screenPoints  =  [ bd.WS(p) for p in points ]  # From world to screen Coordinates (in another array)
        bd.DrawPoints(screenPoints, vc = None, colcnt=1, vn=None)

        return c4d.DRAWRESULT_OK

Code:

import c4d, urllib2, os

url = r"https://www.patreon.com/posts/24993001"

f = os.path.join(os.path.dirname(c4d.storage.GeGetStartupApplication()), "resource", "ssl", "cacert.pem")

urllib2.urlopen(url, cafile=f)

Error:

urllib2 no longer has any effect in Cinema 4D.
It is worth mentioning that I did not change anything in my code. It was working like a charm.
I doubt the latest windows update corrupted it.
Are there any solutions to bypass this limitation?

OK. Now I get it.

Thank you very much! I really appreciate what you've done.

Have a good day!

OMG! You just wrote the entire plugin for my silly question.
Thank You!!!

I have only one question.
Why did you use
Draw(self, op, drawpass, bd, bh)
instead of
Draw(self, tag, op, bd, bh)
will not drawpass be treated as op and op as a tag?

The method above causes shading problems which can be solved by enabling depth option. bd.SetDepth(True)

But it's still displayed on the background. Is it possible to bring it to the front?

Seems like I figured this out but it's kinda complicated.

    def Draw(self, tag, op, bd, bh):

        values0 = [{'_txt': "Hello", "_position": v(100,100,0)},{'_txt': "World", "_position": v(200,200,0)}]

        bd.DrawMultipleHUDText(values0)

        return c4d.DRAWRESULT_OK

I want to display these values on top of other viewport elements.

Hello PluginCafe!

I'm using Draw() method if TagData plugin for displaying multiple text values but I can't figure out, how the DrawMultipleHUDText works.

Let's assume I have a list of strings
abc = [ "Hello", "World", ]

And a list of vectors (Usually I'm importing c4d.Vector as v)
xyz = [v(0,100,0), v(0,200,0)]

How should I pass them into DrawMultipleHUDText?

I tried this method and it does not work.

    def Draw(self, tag, op, bd, bh):

        abc = ["Hello", "World"]
        xyz = [v(0, 100, 0), v(0, 200, 0)]

        values = {'_txt': abc, "_position": xyz}

        bd.DrawMultipleHUDText(values)


        return c4d.DRAWRESULT_OK

Thanks, Manuel!

Don't spend more time on this. I already know about "brute force" methods, so I probably will use it in my code.

I'm making a free, open-source spline object plugin which will contain spline object properties.

Its Angle, Number, and Maximum Length values are ghosted according to the Interpolation Points value. I do not want to mislead people and use complicated snippets in my code, but if this is the only way, then I will INCLUDE spline data in the .res file which can be ghosted directly from .pyp file via GetDEnabling

    def GetDEnabling(self, node, id, t_data, flags, itemdesc):

        spline_type = node[c4d.SPLINEOBJECT_INTERPOLATION]

        if   spline_type == 0: ghost1,ghost2,ghost3 = False, False, False
        elif spline_type == 1: ghost1,ghost2,ghost3 = True , False, False
        elif spline_type == 2: ghost1,ghost2,ghost3 = True , False, False
        elif spline_type == 3: ghost1,ghost2,ghost3 = False, True , False
        elif spline_type == 4: ghost1,ghost2,ghost3 = False, True , True

        if id[0].id == c4d.SPLINEOBJECT_SUB:            return ghost1
        if id[0].id == c4d.SPLINEOBJECT_ANGLE:          return ghost2
        if id[0].id == c4d.SPLINEOBJECT_MAXIMUMLENGTH:  return ghost3

        return True
