I'm working on a plugin that needs to free some resources as well as closing a TCP connection, unfortunatly you cannot rely on C4DPL_ENDPROGRAM since if your scene is not saved and try to close c4d that signal is trigged but you still can click on Cancel so the app is not closed and you could have freed your resources.

Any thought on this? Thank you in advance.

@r_gigante It was about updating an object during the render process but I used a different aproach just by sending the object's doc to that function so I think it could be solved already.

I'm using BaseDocument
*doc = GetActiveDocument();
to get the document we are using and

const UnitScaleData docScaleData = (const UnitScaleData)doc->GetDataInstance()->GetCustomDataType(DOCUMENT_DOCUNIT, CUSTOMDATATYPE_UNITSCALE);
Float otherScale = 1.0f;
docScaleData->GetUnitScale(otherScale, docunit);

to get the units in the scene, unfortunatly GetActiveDocument() returns a doc named "Untitled 1" in Team Render rendering process so I cannot get the scene units.

Is there any way to get the current scene or units during a Team Render rendering session?

@y_puech said in ParseTupleAndKeywords in R20:

Hi Victor,

There's a logic error in the code you posted from the first post. The condition for R20 if (str.IsEmpty()!=false) returns false if the string has content.
It makes more sense to call IsPopulated() for the R20 code instead of IsEmpty().

You are right, thank you!!!

I didn't change nothing from the version that works ok in R19

moduleFunctions[0].Init("MakeThing", (PyFn)MyprojectPyAPI_MakeThing, PYFN_FLAGS::KEYWORDS, "MakeThing(str path)");

We are adding new Python functions to Cinema and our solution works fine in R19 and previous versions but we are having problems parsing the parameters in R20

static _PyObject *MyprojectPyAPI_MakeThing(_PyObject *self, _PyObject *args, _PyObject *keywords)
{
	PythonLibrary pylib;

	String str;

	const Char *kwlist[] = { "str", nullptr };
	if (!pylib.ParseTupleAndKeywords(args, keywords, "$", kwlist, &str))
		return nullptr;

  #if API_VERSION < 20000
	  if (str.Content())
  #else
	  if (str.IsEmpty()!=false)
  #endif
	{            
		Utils::addLog("Parameter is: " + str);
	}
	else
	{
		Utils::addLog("Cannot parse the parameter correctly.");
	}

	return pylib.ReturnPyNone();
}

As you can imagine the problem is that it always throws "Cannot parse the parameter correctly."

Any idea on what is wrong for R20? something related to PythonLibrary changed?

Thank you in advance!

In our case it was a bit more complex but we managed to bypass the issue using load delay dlls.

Thank you all!

We have a plugin that has lots of third party dependencies like Qt and others.

In the past (R19 and older versions) we had a loader plugin that loads all this third party dependencies and makes a hook by defining c4d_main(LONG action, void* p1, void* p2, void* p3) and calling c4d_main(LONG action, void* p1, void* p2, void* p3) in other dll we it did by using GetProcAddress(hModule, "c4d_main");

It worked like a charm until r20. With the introduction of the new project scheme and the autogenerated code, it seems like any calls done to the core or cinema frameworks inside the DLL we manually load just crash due to missing initialization on some of the internal maxon components.

We've made sereval tries like skipping that GetProcAddress call and putting the .dll as other plugin in C4D but it seems that or first plugin (the one that loads the dependencies) is not making its work (we tried to load the dependencies on PluginStart and in PluginMessage) so it is not loaded (and no error message is triggered neither)

We believe this might be because C4D is calling more routines than c4d_main since R20 on the plugins, so our method is no longer compatible unless we replicate C4D's behavior.

Any thought on this?

How could I add a string parameter to that function? I mean to ExtendPyAPI_HelloPython,

Regards, Víctor

I have an asychronous call that needs to update the panel interface of my plugin for this I make something like:
((BaseObject*)this->Get())->GetDataInstance()->SetString(OBJECT_INFO, MaxonString("New value of the text string"));

Unfortunatly until I select again the same object I don't see this change in the interface.

Any tip on this?

Thank you in advance.
