Hello folks!
Let me introduce you my new plugin, which is good solution for those people who developing file handling scripts for Cinema 4D R19 and higher.
The Batch Processor plugin allows to convert between all the 3D formats that are supported by Cinema 4D and supports User Scripts, including scripts with User Interface. Plugin installation contains several scripts that can be used as an example. Also plugin help contains all the necessary information about developing scripts with Batch Processor compatibility.
Using the Batch Processor, the developer needs to write only code part for processing the document, the plugin takes care of the rest (opening-saving file,collecting, display and saving the script results log).
Here is an example Demo Script:
import c4d from c4d import gui ''' Batch processor User Script Basic Example Please follow the code comments https://mikeudin.net/ To add User Scipt dialog make sure: 1. Your dialog is based on gui.Subdialog class 2. Class must have a name 'UserScriptDialog' 3. Class must have a class variable 'user_script_container' to store all data on it 4. Script must have 'main' function that will be executed by Batch Processor 5. 'user_script_container' from dialog will be used as input argument for 'main' function ''' class UserScriptDialog(gui.SubDialog): """ A SubDialog to display the passed string, its used as example for the actual content of a Tab """ STRING_FIELD = 2000 INT_FIELD = 2001 # define user_script_container as dictionary user_script_container = dict() def CreateLayout(self): # Add your dialog gui elements as descibed on Cinema 4D Python API # Please use methods which is compatible with Cinema 4D R19+ Python API bc = c4d.BaseContainer() bc.SetBool(c4d.QUICKTAB_BAR, True) bc.SetString(c4d.QUICKTAB_BARTITLE, 'Script Options') self.AddCustomGui(1000, c4d.CUSTOMGUI_QUICKTAB, '', c4d.BFH_SCALEFIT, 0, 0, bc) if self.GroupBegin(1001,flags=c4d.BFH_SCALEFIT | c4d.BFV_TOP,cols=2,rows=1,title='Script Options'): self.GroupSpace(15, 6) self.GroupBorderSpace(15,5,15,10) self.AddStaticText(1002, c4d.BFH_LEFT, name='My String Data') self.AddEditText(self.STRING_FIELD, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 10) self.AddStaticText(1003, c4d.BFH_LEFT, name='My Integer Data') self.AddEditNumberArrows(self.INT_FIELD, c4d.BFH_LEFT | c4d.BFV_SCALEFIT, 80, 10) self.GroupEnd() return True def Command(self,id,msg): # Assign data to 'user_script_container' variable on any user gui interaction if id in {self.STRING_FIELD,self.INT_FIELD}: self.user_script_container['int'] = self.GetInt32(self.INT_FIELD) self.user_script_container['string'] = self.GetString(self.STRING_FIELD) return True # On execution 'user_script_container' will be used as input argument for 'main' function. # if User Scipt do not contains dialog, 'main' function will be executed without arguments. def main(data): ''' Batch Processor adds some global variables to User Script: doc - referenced to a processed document, type: c4d.BaseDocument doc_index - referenced to an document index in Jobs Queue, type: int docs_total - total number of documents in a Jobs Queue, type:int op - Active Object of processed document, type: c4d.BaseObject mat - Active Material of processed document, type: c4d.Material tp - Particle System of processed document, type: c4d.modules.thinkingparticles.TP_MasterSystem ''' # All data that needed to be printed will be passed to plugin Log tab print 'Processed Document Index {0} from {1}'.format(doc_index,docs_total) print 'Document name: ', doc.GetDocumentName() print 'Document path: ', doc.GetDocumentPath() print 'Document Active Object is ', op print 'My String data', data['string'] print 'My Integer data', data['int'] if 3 < doc_index < 7: # If index of processed document have a number 4,5,6 # in this case User Scipt will return error raise Exception('Error!')
Here is how it works:
I hope the Batch Processor will be the solution that will help automate your work on processing a large number of files using the Cinema 4D Python API!
You have to combine objects to null, for example:
import c4d from c4d import gui def smc(listy): null = c4d.BaseObject(c4d.Onull) for o in listy: o.InsertUnder(null) res = c4d.utils.SendModelingCommand(command = c4d.MCOMMAND_JOIN, list = [null], mode = c4d.MODELINGCOMMANDMODE_ALL, bc = c4d.BaseContainer(), doc = doc) return res[0] def main(): obs = doc.GetActiveObjects(0) doc.InsertObject(smc(obs)) c4d.EventAdd() if __name__=='__main__': main()
How to use this tool with objects grouped in a single null? Not working with Figure primitive :
Traceback (most recent call last): File "C:\Users\user\AppData\Roaming\MAXON\Cinema 4D R20_4FA5020E\plugins\OnFloor_1.0.0\OnFloor\OnFloor.pypv", line 108, in MouseInput File "C:\Users\user\AppData\Roaming\MAXON\Cinema 4D R20_4FA5020E\plugins\OnFloor_1.0.0\OnFloor\OnFloor.pypv", line 47, in CenterAxe File "C:\Users\user\AppData\Roaming\MAXON\Cinema 4D R20_4FA5020E\plugins\OnFloor_1.0.0\OnFloor\OnFloor.pypv", line 24, in MoveAxe ValueError: Invalid object length.
Just in case. Using my Target4D plugin you can drop your object to any surface
May be there is unicode symbols problem. Try this
f = open(fn.decode("utf-8"))
@bentraje You have to edit your "C:\Program Files\MAXON\Cinema 4D R20\resource\modules\python\libs\python27\c4d_init_.py" file by adding all symbol ID's as module variables.
Check out an example file, make sure you have a backup!
Hello guys! Hope you find it interesting. I've written little script which sends copied text to differents web pages for search. This script will be very helpfull to work with Cinema4D online SDK directly from Script Manager or Expression Editor.
Download for free here.
@klints2 Try to use IsolateObjects
A helper routine to copy the objects of document to a new document (returned). All materials associated are also copied over and the links are corrected.
Hello guys! I've created little solution to send python code to execute in Cinema 4D. Also it works for editing Pyton Generators, Effectors, Tags and Fields! Thanks for Remote Code Runner - Cinema 4D & Sublime Text plugin by NiklasRosenstein.
Download SendPythonCodeToCinema4D
@kbar Thank you! Great job!
May be Polygonize can help you.
Make a clone of the document and turn all objects into polygon based objects.
@m_magalhaes Thank you!
Hello guys! There is way to know possibility to create take for DescID? Something like a DESC_ANIMATE parameter with values DESC_ANIMATE_OFF, DESC_ANIMATE_ON, DESC_ANIMATE_MIX.
Thank you @noseman!
@noseman said in How to make a Python Plugin...:
convert Scripts to Plugins
There is a nice solution to make it easy https://plugincafe.maxon.net/topic/10699/14153_c4d-prototype-to-plugin-converter
Also a lot of Cinema 4D plugins examples for different cases are presented here https://github.com/PluginCafe/cinema4d_py_sdk_extended/tree/master/plugins
@kbar I think much better to create your own Edit Script dialog with blackjack and... Save and Execute Buttons. Use GeDialog.AddMultiLineEditText with a flags DR_MULTILINE_SYNTAXCOLOR and DR_MULTILINE_PYTHON.
Hello! After dragging to console there is no way to get single value from vector UserData parameter.
>>> Cube[c4d.ID_USERDATA,2,c4d.VECTOR_Z] Vector(0, 0, 0) >>> Cube[c4d.ID_BASEOBJECT_REL_POSITION,c4d.VECTOR_X] 52.0
And no way to set this single value:
>>> Cube[c4d.ID_USERDATA,2,c4d.VECTOR_Z] = 12 Traceback (most recent call last): File "console", line 1, in <module> TypeError: __setitem__ expected c4d.Vector, not int
There is a soution without creating a new c4d.Vector() variable? I need to get dragged to plugin dialog c4d.DRAGTYPE_DESCID from one single vector UserData parameter. Thank you!
Great, thank you guys!
Hi guys! Is it possible to convert string value to BaseTime with this function?
Converts a string to a data value of type float, int or c4d.BaseTime.
>>> c4d.utils.StringToNumber('11', c4d.FORMAT_FRAMES, doc.GetFps()) 11.0 >>> c4d.utils.StringToNumber('11', c4d.FORMAT_SECONDS, doc.GetFps()) 11.0 >>> c4d.utils.StringToNumber(11, c4d.FORMAT_FRAMES, doc.GetFps()) 11.0
After some tests i had no luck with it.️
>>> doc[c4d.DOCUMENT_MINTIME] = c4d.utils.StringToNumber('11', c4d.FORMAT_FRAMES, doc.GetFps()) Traceback (most recent call last): File "console", line 1, in <module> TypeError: __setitem__ expected c4d.BaseTime, not float >>>
Thank you!
Can't open with Chrome but it possible with Safary MacOs.

@cairyn Thank you!
