Hey @aghiad322,

as I said, classic API CustomDataType types (e.g., the "dots" example) realize their serialization via CustomDatatypeClass::Read and ::Write. The DotsDataClass example implements both methods to read and write the dots data. If you want things to be stored, e.g., your gradient, you will have to implement it there. E.g., it could look like this:

Bool MyDataTypeClass::WriteData(const CustomDataType* t_d, HyperFile* hf) { // Cast the passed in data to your datatype. const MyDataType* const data = static_cast<const MyDataType*>(t_d); // Bail when #data is malformed, has no gradient. _gradient is a member of MyDataType and supposed // to be of type Gradient* just as in your case. if (!data || !data->_gradient) return false; // Wrap the dereferenced _gradient as a GeData instance. GeData geData; geData.SetCustomDataType(*data->_gradient); // Write your data into the hyper file and bail if it somehow fails. if (!hf->WriteGeData(geData)) return false; // Write other data members of your datatype. if (!hf->WriteInt32(data->_someInt32)) return false; if (!hf->WriteFloat(data->_someFloat)) return false; if (!hf->WriteBool(data->_someBool)) return false; return true; }

Hey @aghiad322,

please re-read my answer I have given above. You implement a custom data type in C++, your SplineVisDataType in splinevis.h. Then you reference that data type in a resource of a Python plugin (SPLINEVIS ANIMATION_CLONER_SPLVIS { ANIM OFF; };). You will not be able to interact with this parameter/data type in Python until you have ported it or use the other approach I have lined out above - decomposition/channels.

As also lined out above, you will be never able to get-access a parameter with a custom data type you have implemented yourself in Python because C4DAtom.GetParameter hardcodes the casting/unpacking of data types to Python.

Cheers,
Ferdinand

PS: And if you only want another way to display SplineData, you can also just write a custom GUI targeting that data type. There is no necessity to always write your own custom data type for a custom GUI, you can also target existing ones. You would then have to set the custom GUI to yours when you define a SPLINE element in a dialog or description resource

@ferdinand Thanks a lot it worked

Thanks a lot @i_mazlov that's exactly what i needed.
however on one of the options for the dropdown i have a single Text input that spans across the whole attribute manager, now after i added the "STATICTEXT { SCALE_V; }" it eats up half the space in the image below
Screenshot 2023-12-22 211432.png
i tried to give it a Description id and treat it as any other parameter and hiding it using "c4d.DESC_HIDE", below is the layout of the whole tab

GROUP ADVANCED_TAB { SCALE_V; STRING CUSTOM_TXT_PARAMETER{ ANIM OFF; CUSTOMGUI MULTISTRING; SCALE_V; WORDWRAP; }; GROUP{ COLUMNS 2; LONG ANIMATION_CLONER_FROM { MIN 0; ANIM OFF; }; LONG ANIMATION_CLONER_TO { MIN 0; ANIM OFF; }; LONG ANIMATION_CLONER_SPAN { MIN 1; ANIM OFF; }; GROUP{ COLUMNS 1; SEPARATOR ANIMATION_CLONER_SEPARATOR{ LINE; }; REAL ANIMATION_CLONER_MULTIPLIER { MIN 0.1 ; STEP 0.1 ; ANIM OFF; }; } } GROUP{ COLUMNS 2; REAL SWEEP_PRO_RADIUS { UNIT METER ; STEP 0.1 ; MIN 0.1; ANIM OFF; }; REAL SWEEP_PRO_MULTIPLIER { MIN 0.1; ANIM OFF; }; } STATICTEXT UI_FILLER{SCALE_V;} GROUP{ COLUMNS 2; LONG PRESET { ANIM OFF; CYCLE { ANIMATION_CLONER; SWEEP_PRO; CUSTOM_INPUT; } } } }

but when i try to hide it from the "GetDDescription()" the description "description.GetParameterI(paramId)" is empty ! ,in the "GetDDescription()" in my source code i have the hiding for the other parameters implemented as well but didn't copy them to keep the snippet at minimum lines

def GetDDescription(self, node: c4d.GeListNode, description: c4d.Description, flags: int) -> typing.Union[bool, tuple[bool, int]]: if not description.LoadDescription(node.GetType()): return False, flags paramId: c4d.DescID = c4d.DescID(c4d.DescLevel(c4d.UI_FILLER, c4d.DTYPE_STRING, 0)) evalId: c4d.DescID = description.GetSingleDescID() if (evalId and not paramId.IsPartOf(evalId)): return True, flags paramData: c4d.BaseContainer = description.GetParameterI(paramId) #paramData for the "c4d.UI_FILLER" is empty if paramData is None: return True, flags # parameter ID_HIDE_CONDITION. paramData[c4d.DESC_HIDE] = True if node[c4d.PRESET] == c4d.CUSTOM_INPUT else False return True, flags | c4d.DESCFLAGS_DESC_LOADED

Hey @aghiad322,

Great to hear that you solved your problem. And although I understand how you meant your last sentence, the questions of users are never inconvenient to us. All questions are welcome, but sometimes we must draw some boundaries for the scope of support.

Hello @aghiad322,

I have closed this thread as it has been answered. The task has been added to our internal task pool. However, since this is not a bug but a feature limitation, I have not marked this thread as to_fix as there is nothing to fix here.

This does not mean that we will not do it, I have added the task for now to the task pool of a close by release. But we treat feature requests differently than bugs, and the task might therefore be postponed/pushed when we run out of time in that release.

Cheers,
Ferdinand
