Hi sorry to jump on this topic so late, and I agree that if you could do what you want in a Python Scripting tag its preferred, the mains issue with xpresso is that its a whole system that assumes certain things and was really not designed to be embedded within a generator.

So the issue about the AddNode, not working is because user data things, as an object xpresso node, is something dynamic (they will change according to the linked object) and I found no way except via the UI (by asking a UI Redraw or a whole scene execution) to refresh these data so the GvPort can be created.

But since you are in a Generator you don't have access to the GUI since all GUI operation should be done in the Main thread see Threading Information.

Cheers,
Maxime.

Okay!
Thanks for the info @m_adam !

While the method provided by Zipit Is fine, it is not 100% reliable.

here how to achieve, unfortunately, the ELEMENT_Count value is hardcoded and no way for you to retrieve it.

constraintTag = doc.GetActiveTag() targetCount = constraintTag[c4d.ID_CA_CONSTRAINT_TAG_PARENT_TARGET_COUNT] for i in range(targetCount): CONSTRAINT_ELEMENT = 10 # This is hardcoded targetId = c4d.ID_CA_CONSTRAINT_TAG_PARENT_TARGET_COUNT + i * CONSTRAINT_ELEMENT + 1 print(constraintTag[targetId])

Thank you Manuel !! this is exactly what I was looking for 😊

@mp5gosu

Ah brilliant. Thanks for that!

And apologies for being such a noob at this.

Yes, I must read the manuals more throroughly (RTFMS).
Excuses: it is so much and I just wanted to compiler R20 in R21.
But you are correct.

BUT, adding iferr to the code worked, AND also solved the other issue.
Everything is working now!

Thanks!

hi,

that really depends on what you are doing.
There's different type of lock for different cases and scenario.

That also depends on what you care first, speed or memory.

but the manual is pretty easy to understand, just pass the lock as a reference to your lambda function and you should be good to go.

Cheers,
Manuel

Hi @lasselauch there is actually no plan to update ResEdit.

There is the R20 Resource Editor but for the moment it's only for Node stuff.

Cheers,
Maxime.

Thanks for the drag'n'drop tip Maxime, that feature is extremely useful!

Hi Pim sorry for the late reply, this is possible by using the lib_py.h (typically this is somehow what we used before R20 to expose feature in python, but it's way elder, not everything is possible to do, you have less control than with the new python.framework, and the lib_py.h is not maintained (so don't expect any enhancement in it) Only the python.framework will be enhanced.

// Init Python GePython pythonScope; pythonScope.Init(); // Acquiere the GIL GePythonGIL gil_state; pythonScope.SetNode("doc", doc); // If doc->GetFirstObject() is nullptr, op variable will not be declared in the python scope, and you cant add a None. pythonScope.SetNode("op", doc->GetFirstObject()); maxon::String pythonCode = "\ import c4d\n\ \n\ def main():\n\ print(doc, op)\n\ \n\ if __name__ == '__main__' :\n\ main()\n\ "_s; StopAllThreads(); pythonScope.Run(pythonCode);

Cheers,
Maxime.

Ah, you probably expect the toroids to also rotate around their own axis

exactly. Thanks

@mp5gosu thanks for the addition.

Cheers,
Manuel

Without a further reply from you until tomorrow I will consider and mark this topic as solved, but feel free to open it again if you have more information.

Cheers,
Maxime.

@m_magalhaes
Oh man... thank you so much. Even when I read your reply, I couldn't "see" it in the Node... was staring at it for to long.
thanks.

Thanks again @PluginStudent for helping me so quickly.

That was enough information to help me find the .MakeUserSpline function that allows me to do exactly what I'm after:

MakeUserSpline('sin(x * PI)', 5)

More info here for anyone looking.

Cheers,
Jamie

Oops - I forgot to have the following line:

myDefObj[c4d.FIELDS] = myFieldList

It all works perfectly now. Thanks again for your help @PluginStudent

Hi,

yeah like that. __name__ is just another module bound constant attribute. It is a dunder attribute, signaling a special importance, indicated by its double underscores, but that is only a convention and not a functionality. You can set __name__ to anything you like, just like you could set __author__ to your favourite ice cream brand. The convention dictates that __name__ tells the script in which context is being executed, where __main__ should signal that the module is executed directly. You could set it to my_cpp for example, so that your scripts could react differently to being executed from your C++ code.

Cheers,

To summarise, there are 2 projectdefinition.txt files.

on main / sdk level, Define which project (plugins, etc.)
Example: Platform=Win64;OSX Type=Solution // defines the level of rigour of the source processor's style check stylecheck.level=0 Solution=\ plugins/cinema4dsdk;\ plugins/maxonsdk.module;\ plugins/commandline;\ plugins/CommandLineRendering on plugin level, // Configuration of a custom solution in the projectdefinition.txt file
Example: // Supported platforms Platform=Win64;OSX // Type of project Type=DLL // this plugin depends on these frameworks: APIS=\ cinema.framework; \ misc.framework; \ image.framework; \ core.framework; \ python.framework // Enable some advanced classic API support; not needed for hybrid plugins C4D=true // Plug-in code-style check level stylecheck.level=0 // Custom ID ModuleId=net.maxonexample.commandlinerender

@r_gigante said in attribute 'nodiscard' requires compiler flag '/std:c++17':

Well @pim , that's indeed the issue. Sticking to the recommended IDE is always recommended.

Indeed going back to VC++2015 solved the issues.
But now I have problems with the python.framework.
