Thanks Ferdinand.
with info=c4d.PLUGINFLAG_TOOL_EDITSTATES everything works fine.

I mark your answer as correct.
is it the right way to set the topic as solved?

@ferdinand
Thanks.
I will be away in the next days.
I will try it as soon as possible and inform you about the result.

P.S . when the "info" is set as in your example, the isoline editing checkbox in the viewport configuration is automatically seen by the plugin or I have to configure the basedraw setting in the code?

with Mpolygons mode and the move tool active:

and when my tool is active:

what I meant with "expanding" is creating a tool that can remember the selection order of polygons.
and use this selection for custom functions.

thanks again
please tell me if you need more information

mdr74

@ferdinand sorry to bother you again.
I think I'm not able to exactly describe my request, maybe it's my poor english or bad terminology

I'm trying to create a tool plugin for expanding the selection tool with custom functionality.
And when I switch to it, the isoline editing (still enabled in the basedraw) seems disabled in the viewport.

If I edit a polygon object under HN I'd like to have the same display that I have with the move tool, but I have the same display of the loop cut tool. I don't know if it's possible or where I have to set a specific option (maybe in the draw method ?)

I added this:

print(bd[c4d.BASEDRAW_DATA_SDSEDIT])
print(bd.IsViewOpen(doc))

in the Draw and MouseInput method and the result is always 1 and True

I'm using ViewportSelect GetNearestPolygon to select the polygon under the mouse.

I hope it's everything clear...

thank you

mdr74

Thank you.
But I realise I used the wrong option.
I was trying to enable the isoline editing while in polygon mode inside my tool.
I know that some tools, like Loop cut for example, are not using isoline display, but I don't know if it's a choice or is it impossible to enable it.
While using my tool, in the viewport settings the option is enabled, but I think it also depends on some unknown features

Sorry for the confusion.
Do you need me to change the post title?

mdr74

Hi, I'v searched the forum but I didn't find any solution.
I'm developing a tool plugin with python for polygon manipulation.
Is it possible to enable ~~deformed~~ isonline editing in the viewport for the selected object under a HN?

thanks

edit [ferdinand]: changed the title the word in the question

mdr74

Thanks a lot !!!.
I will try it in the next days.
I'm free for my personal projects only during weekends

mdr74

I don't know exactly how and why, but I found the solution.
setting the basedraw matrix relative to the object when deformer is selected

It's not a clean solution, but I cannot understand the hierarchy cache problem

the modified method is:

def DrawPolyNormals(self, obj):
        for p, n in zip(self.objPolysCenter, self.objPolysNormal):
            mx = self.mx
            if obj.GetDown():
                if obj.GetDown().GetBit(c4d.BIT_ACTIVE):
                    self.basedraw.SetMatrix_Matrix(None, mx)
                else:
                    self.basedraw.SetMatrix_Matrix(None, c4d.Matrix())
            normalDistance = n * self.normalLength
            q = p
            r = q + normalDistance * c4d.Matrix(v1=~mx.v1, v2=~mx.v2, v3=~mx.v3)
            self.basedraw.DrawLine(q, r, 0)

the object points global position are calculated in self.objPolysCenter:

def polysCenter(self, local=False):
        polys = self.polyPlgList
        pts = self.polyPtsList
        nbPolys = self.polyPlgCount
        center = vc()

        for i, poly in enumerate(self.polyPlgList):
            if poly.c != poly.d:
                center = (pts[poly.a] + pts[poly.b] + pts[poly.c] + pts[poly.d]) / 4
            else:
                center = (pts[poly.a] + pts[poly.b] + pts[poly.c]) / 3
            if not local:
                yield center * self.mx
            else:
                yield center

@zipit
I can wait, no hurry

Just to let you know...the same problem occurs with polygonal object and deformer
everything's correct in world center but as soon as I move the object it seems that the matrix are calculated 2 times.
It seems a cache issue

I'm checking the link provided

cheers

mdr74

@zipit
Thanks

I corrected the matrix calculation as suggested but the problem persist.
I'll try to check the cache issue thread you linked

for now I upload the plugin...it's very messy I think, but I use it also for testing other things ;):
PLUGIN

I also attach 2 screenshots of the problem

when there is no deformer everything's correct (with base object and polygonal object):

as soon as I put a deformer below the lines shift away:

the same problem occurs when I change the deformer alignment to other planes and fit to parent:

thanks for the support

mdr74

Hi,
I'm trying to write a Tag plugin to visualise data on objects.
Everything's work fine until I put a deformer under the object and get the deformed Cache.
In that case, the matrix of the generated Lines are translated ( I think they are calculated twice or something similar ).

@mikeudin I change this code in line 432 of SendPythonCodeToCinema4D.pyp

str(code)

with

str(code, "utf-8")

and also in lines 436, 440, 448

the code returned to cinema4d was in byte format, not string.
I'm not very good with python but it works for me

mdr74

@mikeudin thanks

Hi,
is it possible to update this fantastic tool for R23.
I think it's broken due to new python 3.7 version, but I don't understand the socket module

thanks

mdr74

I discovered another problem in S22, maybe.
The Hud text is correct but when I deselect the polygon object I cannot select anything in the viewport anymore.
I don't know if it's a bug or an error in the plugin

thanks again

mdr74

it works.
thanks

mdr74

I started again from scratch and now it works but only in R21.
In S22 here's no error in the console but nothing shows in the viewport (the object is a polygon).

mdr74

Hi Manuel,
I've tried to follow your example from the thread you linked but it gives me "Could not initialize global resource for the plugin"

I thought it was solved, maybe something is changed in R21 or S22?

thanks

mdr74

Found it

I think it needs a string not an int

nul = c4d.BaseObject(c4d.Onull)

mdr74

Hi,
I'm trying to write a python script to create a Null with a custom icon (with the same icon ID of the PBR light, just for test)
but I cannot modify the icon.
it give me no error so I don't know what's wrong

thanks
