It seems the old c4dtools were integrated into c4ddev
sadly c4ddev is nothing for the occasional c4d python hacker .-)

the "beginners guides" are on "todo" for years, now and probably wont get completed anymore.
it does not look like Niklas is still engaged in the c4d world.

@zipit Thanks!

Hi:

This is a bit of a hassle, but can still be scripted, who CARES about an extra polygon.

import c4d def main(): polygons = op.GetAllPolygons() points = op.GetAllPoints() point = [c4d.Vector(10000, 10000, 10000),c4d.Vector(9999, 10000,10000), c4d.Vector(9999, 10000, 10001),c4d.Vector(10000, 10000, 10001)] point_indexe = [[len(points) + i ,point[i]] for i in range(len(point))] op.ResizeObject(len(points) + len(point),len(polygons) + 1) set_point = [op.SetPoint(k[0], k[1]) for k in point_indexe] op.Message(c4d.MSG_UPDATE) c4d.EventAdd() if __name__=='__main__': main()

Hi Fernando, feel free to have the developer writing directly to our sdk support email box.

Best, R

Wow, very nice! There's a huge progress, it now works pretty fast.
Thanks for adding the wishlist items. 🙂

Grand merci pour ce Plugin tellement simple et facile d'utilisation. Grand merci...
Many thanks for this Plugin so simple and easy to use. Big thanks

The issue is fixed by the way. 😉

Hi, here in Cinema 4D S22 defining the type of the cloner I don't have anymore an issue

import c4d from c4d import gui import math def main(): # Build Parent Cloner cloner = c4d.BaseObject(1018544) cloner[c4d.ID_MG_MOTIONGENERATOR_MODE] = c4d.ID_MG_MOTIONGENERATOR_MODE_LINEAR doc.InsertObject(cloner) # Build Null newnull = c4d.BaseObject(c4d.Onull) newnull.InsertUnder(cloner) # Build Children Cloner internal_cloner = c4d.BaseObject(1018544) internal_cloner[c4d.ID_MG_MOTIONGENERATOR_MODE] = c4d.ID_MG_MOTIONGENERATOR_MODE_GRIDARRAY internal_cloner.InsertUnder(newnull) internal_cloner.Message(c4d.MSG_MENUPREPARE, doc) # Cube cube = c4d.BaseObject(c4d.Ocube) internal_cloner.Message(c4d.MSG_MENUPREPARE, doc) cube.InsertUnder(internal_cloner) # Xpresso Tag xtag = c4d.BaseTag(c4d.Texpresso) cloner.InsertTag(xtag) # Setup Parent Cloner cloner[c4d.MG_LINEAR_OBJECT_POSITION, c4d.VECTOR_Y] = 0.0 cloner[c4d.MG_LINEAR_OBJECT_POSITION, c4d.VECTOR_Z] = 500.0 cloner[c4d.MG_LINEAR_COUNT] = 10 cloner[c4d.MGCLONER_VOLUMEINSTANCES_MODE] = c4d.MGCLONER_VOLUMEINSTANCES_MODE_RENDERINSTANCE # Setup Children Cloner internal_cloner[c4d.MG_GRID_SIZE] = c4d.Vector(300, 200, 100) # Setup Cube cube[c4d.PRIM_CUBE_LEN] = c4d.Vector(20, 10, 100) # Setup Xpresso # http://mograph.net/board/index.php?/topic/26338-creating-xpresso-nodes-with-python-script/ nodemaster = xtag.GetNodeMaster() node1 = nodemaster.CreateNode(nodemaster.GetRoot(), c4d.ID_OPERATOR_OBJECT, None, 100, 100) node1[c4d.GV_OBJECT_OBJECT_ID] = internal_cloner gridResParam = c4d.DescID(c4d.DescLevel(c4d.MG_GRID_RESOLUTION, c4d.DTYPE_VECTOR,0), c4d.DescLevel(c4d.VECTOR_Z, c4d.DTYPE_REAL,0)) node1out = node1.AddPort(c4d.GV_PORT_OUTPUT, gridResParam) node2 = nodemaster.CreateNode(nodemaster.GetRoot(), c4d.ID_OPERATOR_OBJECT, None, 300, 100) node2[c4d.GV_OBJECT_OBJECT_ID] = cloner posParam = c4d.DescID(c4d.DescLevel(c4d.MG_LINEAR_OBJECT_POSITION, c4d.DTYPE_VECTOR,0), c4d.DescLevel(c4d.VECTOR_Z, c4d.DTYPE_REAL,0)) node2in = node2.AddPort(c4d.GV_PORT_INPUT, posParam) # Connect if node1out is not None and node2in is not None: node1out.Connect(node2in) c4d.EventAdd() # refreshed viewport to see changes automatically if __name__=='__main__': main()

And as pointed by @PluginStudent the problem was because the AddPort fails. And I guess it failed because at the time you ask for the port creation since no explicit mode was defined in the Cloner the XPresso description was not properly fed so this GvPort didn't exist.

Cheers,
Maxime.

hi,

if you wants to know how many AOVs you need for 10 objects you should use Ceil. After that, some math to have your ID raising by 1.

numberOfAOVs = math.ceil(10 / 3.0) # will give you 4 for i in xrange(int(numberOfAOVs)): print ("create aov number {}".format(i)) for j in xrange (3): print ("value of field will be : {}".format(j + i * 3 ) )

I'm not a big fan of retrieving all the objects on each function. But first, make things works, than optimize. (at least at the beginning)

Cheers,
Manuel

Thanks! For whatever reason I couldn't get that particular code to work, but I eventually figured out a different method. I think my script is finished for now. 👍

Thank you very much for your help to solve the previous doubts. I will continue to work hard.

Thanks for the answer.
I will check it.

Thank you @zipit and @m_magalhaes for your replies! @zipit your response put me on the right track. The issue was that I was trying to do all of the conversions using C4D's left-handed coordinate matrices, and it was auto-fixing my "malformed" matrices.

I ended up porting the Three.js Matrix4 and Euler classes from JS to python and using them in my script.

So, the final code (leaving out the ported methods) looked something like:

mg = self.op.GetMg() parent_mg = self.op.GetUpMg() c4d_to_three = c4d.Matrix( off=c4d.Vector(0), v1=c4d.Vector(1, 0, 0), v2=c4d.Vector(0, 1, 0), v3=c4d.Vector(0, 0, -1) ) # Convert to new coordinate space # http://www.techart3d.com/2016/02/convert-left-handed-to-right-handed-coordinates/ mg_three_coords = c4d_to_three * mg * c4d_to_three parent_mg_three_coords = c4d_to_three * parent_mg * c4d_to_three mg_mat4 = Matrix4(mg_three_coords) parent_mg_mat4 = Matrix4(parent_mg_three_coords) inv_parent_mg_mat4 = parent_mg_mat4.Clone() inv_parent_mg_mat4 = inv_parent_mg_mat4.Inverse() node_local = inv_parent_mg_mat4.Clone() node_local = node_local.MultiplyMatrices(inv_parent_mg_mat4, mg_mat4) position, scale, rotation = node_local.Decompose() if position != c4d.Vector(0): self.props["position"] = position if scale != c4d.Vector(1): self.props["scale"] = scale if rotation != c4d.Vector(0): self.props["rotation"] = rotation

hi @SuperHomiak welcome to the forum.
Thanks @zipit for the answer 🙂

For your next threads, please help us keeping things organised and clean. I know it's not your priority but it really simplify our work here.

Q&A New Functionality. How to Post Questions especially the tagging part.

I've set the thread to a question and marked zipit answer as the right answer 🙂

Cheers,

hi,

I'll set this thread as solved without feedback from your side.

Cheers,
Manuel

@Cairyn @zipit @C4DS

Thank you all for the responses.
I ended up with @C4DS suggestion in using SpecialEventAdd() and CoreMessage for simplicity sake.

Have a great day ahead!

Hi,

@SolarPH said in Python - InExcludeData initialization problem:

Now I know that initializing the InExcludeData is not InExcludeData.__init__ and the correct way was c4d.InExcludeData(), ...

I am not quite sure how you did mean this, but InExcludeData.__init__ is one of the methods called when you invoke c4d.InExcludeData(). Like all double underscore methods __init__ implements an operator, in that case the construction operator. Invoking SomeClass() will first call the constructor SomeClass.__new__ and after that the initialisator SomeClass.__init__. Due to the fact that __new__ only rarely has to be implemented explicitly and because people are accustomed to talking about constructor functions, __init__ is also often called a constructor, while technically it is just the initialisator. A prime example would be both the InExcludeData documentation and my example code, which both talk about a copy constructor, but are actually referring to __init__ and not __new__.

Cheers,
zipit

Thanks for the clarification.
Have a great day ahead!
