Hello,

I have a CommandData Python plugin that contains different options.

When I assign a shortcut to my CommandData, or add it to a custom layout, it opens with the default options.

Is is possible to define different shortcuts or custom layout icons that pass parameters to my CommandData plugin and then preset different options ?

For example, imagine a shortcut that execute the Optimize command with the Unused Points checked, and an other one unchecked.
Is it possible ?

Thanks,

Aah ok, I misunderstood indeed. Thanks a lot for your complete answer.
I take a look on all of this.

Mm, it did not work for me, the message was still not triggered even with a message ID higher than ID_TREEVIEW_FIRST_NEW_ID.

I managed in a different way with PluginMessage and c4d.GePluginMessage

But contrarely to what say doc, it's not the easiest way if you want to pass some data lol, the data received from PluginMessage is not an object but a PyCapsule object.

Here is how I retreived the original data object, it's not very elegant but it works :

import ctypes
import _ctypes

def getObjectFromCapsule(capsule):
    ctypes.pythonapi.PyCapsule_GetPointer.restype = ctypes.c_void_p
    ctypes.pythonapi.PyCapsule_GetPointer.argtypes = [ctypes.py_object, ctypes.c_char_p]
    pointer = ctypes.pythonapi.PyCapsule_GetPointer(capsule, None)
    return _ctypes.PyObj_FromPtr(pointer)

def PluginMessage(id, data):
    if id == MY_UNIQUE_ID :
        o = getObjectFromCapsule(data)
        o['foo'] = 'bar'
        return True
    return False

And then in my other plugin :

o = {}
print(c4d.GePluginMessage(MY_UNIQUE_ID, o)) # {'foo': 'bar'}

Hello,

I try to send a message to a CommandData plugin like this :

class MyPlugin(plugins.CommandData):

    def Message(self, type, data):
        print("test", type, data)
        return True

if __name__ == "__main__" :

    plugins.RegisterCommandPlugin(id=1057321,
                                  str="test",
                                  info=0,
                                  help="",
                                  dat=MyPlugin(),
                                  icon=None
    )

And then send the message like this in the console :

c4d.plugins.FindPlugin(1057321).Message(123)

It returns True but nothing print. Do you know why ?

Amazing ! Thanks !

Hello,

The question was posted some years ago but I would like to know if with all the last updates there is now a possibility to add a falloff tab on a Python deformer plugin like in C++ ?

Thanks,

The informations a bit dispatched and I don't find the doc very clear, for example, there is no link to download Project Tool on the Project Tool page, and globally not enough examples in the sdk.

Sorry but the more clear doc to build and update faster our plugins is the tutorial made by a member here, because all the infos are on the same page : https://plugincafe.maxon.net/topic/10967/compiling-the-cinema-4d-r20-c-sdk-examples

Thanks for the info.

By the way, how can we disable the "Style guide" errors ?

For example, all my { after "if" generate an error "Style guide requires a new line for the substatement of if.".

Thanks for your help,

Before all these steps I extracted the sdk.zip into the Cinema 4D R20 folder.

What do you mean by "run the project tool on that "sdk"-folder" ?
I executed the command : kernel_app_64bit.exe g_updateproject="C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins"
where "plugins" folder is from the sdk.zip.

I removed my plugin, to try to build the sdk, but when I open the plugins/project/plugins.sln, I got the exact same error about the file not found :

C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins\microsdk\project\microsdk.vcxproj : error : Le projet importé "C:\Program Files\MAXON\Cinema 4D R20 Demo\frameworks\core.framework\project\core.framework.includes.props" est introuvable. Vérifiez que le chemin dans la déclaration <Import> est correct et que le fichier existe sur le disque. C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins\microsdk\project\microsdk.vcxproj

Edit : My bad, I just needed to execute the tool to the frameworks too :
kernel_app_64bit.exe g_updateproject="C:\Program Files\MAXON\Cinema 4D R20 Demo\frameworks"

I understand now what you mean.

It works now.

Hello,

I tried to make a new plugin with the Project tool, but I got an error when I exec the vcxproj file generated. Here is my steps :

• I created my plugin folder with res and source into the R20/plugins folder.
• I copied the cinema4dsdk/project folder into my plugin folder and changed the custom ID by a new one registered : ModuleId=1050015
• I added my plugin into plugins\projects\projectdefinition.txt
• I exec the command : kernel_app_64bit.exe g_updateproject="C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins", it said it's ok, the files was generated.
• I exec the vcsproj generated into my plugin and I got a Visual Studio Express error saying that C:\Program Files\MAXON\Cinema 4D R20 Demo\frameworks\cinema.framework.includes.props is not found.

I find the documentation to start a new C++ project very messy, and I lost 10 min to understand that the old forum was down and to find the new one, because there is no link nowhere to it on the "How to get Plugin IDs" page. : /
