Hi PluginCafe team!

I'm trying to create a script that weld selected points on the middle. For the scene, I just have the default cube made to an editable object.

It works as expected, but not with the AddUndo.

It gives me a dialog box error of
A problem with this project has been detected: Object "Cube" - Point selection out of bonds

Is there a way around this?

Here is the code so far

import c4d
from c4d import utils

settings = c4d.BaseContainer() 

res = utils.SendModelingCommand(command = c4d.ID_MODELING_WELD_TOOL,  
                                list = [op], 
                                mode = c4d.MODELINGCOMMANDMODE_POINTSELECTION, 
                                bc = settings,
                                doc = doc)
                                
doc.AddUndo(c4d.UNDOTYPE_CHANGE, op)
c4d.EventAdd()

Thank you for looking at the problem

P.S.
From what I understand, if you set the c4d.BaseContainer at empty, it will weld it on the middle by default which is what I want. But just wondering, is there a way to set-it explicitly?

I checked the parameters on the resource section which is follows:

{

	MDATA_WELD_POINT			    				     = 1100, //VECTOR
	MDATA_WELD_TOPOINT                     = 1101, //BOOL
	MDATA_WELD_POINTINDEX                  = 1102, //LONG
	MDATA_WELD_OBJECTINDEX                 = 1103, //LONG
	MDATA_WELD_VISIBLE			               = 1104, //BOOL
	MDATA_WELD_COLLAPSE                    = 1105, //BOOL
	MDATA_WELD_COLLAPSE_P1                 = 1106, //LONG
	MDATA_WELD_COLLAPSE_P2                 = 1107, //LONG
	MDATA_WELD_COLLAPSE_OBJ1               = 1108, //LINK
	MDATA_WELD_COLLAPSE_OBJ2               = 1109, //LINK
	MDATA_WELDPOINT_
};

But the documentation does not provide a description on such parameters. Or maybe I'm missing something out?

Thanks @mp5gosu for the illustration. Works as expected.

Hi,

I'm trying to align a window on a wall. But the wall is angled and I'm having a problem determining the proper orientation.
You can see an illustration of problem here:
https://www.dropbox.com/s/j6rqbvokopn3b6h/c4d084_align_angled_rotation_properly.mp4?dl=0

I was thinking of getting the world rotation of the selected edge, but the coordinate manager does not seem to show anything. You can see the attempt here:
https://www.dropbox.com/s/z03x7faykja0u9c/c4d084_align_angled_rotation_properly.jpg?dl=0

Is there a way to retrieve it using Python?

Thank you for looking at the problem

@m_magalhaes

Thanks Manuel! Works as expected. Didn't expect that you had to add brackets. That was news to me.

Thanks again!

P.S. You also need to add brackets on your example.

Have a great day ahead!

Hi,

I understand that there is a working script from Donovan Keith in this thread.

In his script, he uses GetClone. I'm guessing to have another copy of the object.
I'm trying to rewrite the script without using the GetClone method.

Is this possible?

Here is my script so far:

import c4d
from c4d import utils

res = c4d.utils.SendModelingCommand(
                              command = c4d.MCOMMAND_MAKEEDITABLE,
                              list = op,
                              mode = c4d.MODELINGCOMMANDMODE_ALL,
                              doc = doc )
c4d.EventAdd()

With this script, it gives me an error of
TypeError: GeListNode_mp_subscript expected Description identifier, not long

Did a google search but it doesn't give me any relevant hits.

Is there a way around this?

Thank you for looking at my problem

@m_adam

Thanks for further clarification specially the catch with the dialog's on the script. Will now closed the thread.

Have a great day ahead!

@C4DS

Thanks for the heads-up on DLG_TYPE_ASYNC. It modifies the behavior but it does change the layout unexpectedly. I guess this is for another topic.

Just for clarification:

1. There is no functional difference between calling up a dialogue box from a script and plug-in since they are using the same command anyway
2. Is there a solution for an IDE not recognizing .pyp as python syntax? (I know not directly related to C4D API but just taking chances here)

Thank you for looking at the problem.

Hi,

Is there a difference if I create a floating UI from a Plug-in vs Vanilla Script?

I'm planning to create a floating UI manager where it lists all my scripts for easy access. They are just utility scripts but they are increasing and I would like to categorize them through a floating UI manager for handling

A sample of Dialogue Box vanilla script would be something like this Simple Object Renamer

A sample of Dialogue Box through plug-in would be something like this Python Dialog Tutorial

So far, what I understand in Dialogue Box through Vanilla Script is

You can't access anything when you open a dialogue box through a vanilla script. This makes it a no-go for this particular project where I require a floating UI and still be able to access objects in the scene. Correct me if I'm wrong

Dialogue Box through plug-in seems like a good way to go. The only thing annoying about it is since it is in .pyp the IDE does not recognize the syntax. So I keep renaming it every now and then to .py and back to .pyp. Restart C4D for it to take effect. Other than that. I'm not sure if there are any gotchas compared to the vanilla script.

Basically, I just need a clarification on my understanding above. Sorry for the basic question but coming from Maya almost all dialog box is written as script and not as a plug-in.

Thank you for looking at my problem.

Thanks for the response @m_adam
Have a great day ahead!

@m_adam

Thanks for the response. Works as expected. Appreciate the code a lot.

Just a quick question on GetUserDataContainer()
It returns a tuple: First is the DescID and the second Container.

Running your script as default, it returns a description of
((700, 5, 0), (1, 15, 0))

I run a type() command on this and it returns a DescLevel
In the documentation, it gives a parameter description as follows

t_id (int) – Initial value for id.
t_datatype (int) – Initial value for dtype.
t_creator (int) – Initial value for creator.

There are two DescLevels above.
(1) My question for first one (700, 5, 0) is where did it came from? Why 700 and why 5?

(2) For the second one, I get the 1 as the ID. No question here
For the 15, I get this is a data type but the list is erratic. I tried changing data type on creation and it gave me varied result up to 100+. Is there info where it list all data types with the corresponding int value? (Correct me if I'm wrong but the documentation only provides the str value)
For the 0, not sure why it is zero.

P.S. To be honest, I'm not sure if my additional question is going to help me. Just trying to explore :)

Thanks again for looking at my problem.
