@s_bach Thanks, I ignored the parameter check and it works now！

I recently recompiled my python deformer plugin using C ++, but encountered some trouble.

In function "Message()",I can access the parameters“SSURFACEDEFORMERC_DRIVER” and successfully get the name using GetName ()。
but in function "ModifyObject()", access same parameters“SSURFACEDEFORMERC_DRIVER” failed,return "nullptr".

Thanks for any help!

this is part of code:

Bool SsurfaceDeformerc::Message(GeListNode* node, Int32 type, void* data)

{

	if (type == MSG_DESCRIPTION_COMMAND)

	{

		DescriptionCommand* dc = static_cast<DescriptionCommand*>(data);

		BaseContainer* node_self = (static_cast<BaseObject*>(node))->GetDataInstance();

		BaseDocument* doc = node->GetDocument();



		if (dc == nullptr || node_self == nullptr)

			return true;

		

		if (dc->_descId[0].id == SSURFACEDEFORMERC_INITIALIZE)

		{

                        //successfully access
			BaseObject* obj = static_cast<BaseObject*>(node_self->GetLink(SSURFACEDEFORMERC_DRIVER,doc,Obase));

			ApplicationOutput(obj->GetName());
                }
        return true;
}
//
//

Bool SsurfaceDeformerc::ModifyObject(BaseObject* op, BaseDocument* doc, BaseObject* mod, const Matrix& op_mg, const Matrix& mod_mg, Float lod, Int32 flags, BaseThread* thread)

{


	if (!mod || !op || !doc || !thread)
		return false;

	BaseContainer* data = mod->GetDataInstance();

        //failed access
	BaseObject* obj = static_cast<BaseObject*>(data->GetLink(SSURFACEDEFORMERC_DRIVER, doc, Obase));

	if (!obj)

	{
		ApplicationOutput("No obj!"_s);

		return true;
	}
        return true
}

@zipit Thanks ，"id = 1001148" it work correctly

graphview OpenDialog(id,master),How to set this id to make the xpresso tag open in the default layout?
Thanks for any help!

@zipit Thanks for showing me so much detail.

@m_magalhaes Thanks for your careful answer.
This problem appeared in my mind. My first ideal solution was to control some of the Dialog UI through python. I immediately went to plugin cafe to search for the answer. In fact, I saw the thread.But because of my wrong first ideal solution, I didn't read the article carefully.
I have to read the documentation carefully.

@m_magalhaes Thanks,Solved my problem!

But I still have some doubts and hope to be solved.

• 1: Why drag a weight manager Dialog parameter to the console, the resulting WeightManager is a BaseList2D
• 2: Is there a way to access the opened Dialog and modify its parameters (such as modifying values, CallButton, etc.)

I want to use python to control the weight manager that is already open. For example, the mode switch Smooth ---Add, call button(apply selected), etc., I try to get information in the script log, but it does not seem to work, the following is my code:

tool = plugins.FindPlugin(1025028)
tool[c4d.ID_CA_WEIGHT_MGR_WEIGHT_MODE] = 2  
tool[c4d.ID_CA_WEIGHT_MGR_WEIGHT_STRENGTH] = 0.5
c4d.CallButton(tool,c4d.ID_CA_WEIGHT_MGR_APPLY_SELECTED)

When I drag and drop a weight manger window parameter into the console, I can get a variable WeightManager. I can access and modify the weight manger window parameter through this variable. How can I get this variable through python? As shown below

Thanks for any help!

@m_adam Thanks

Bone Display Set:Polygon,i can change CAJoint point postion in Point Edit Mode.But how can i get more info or change,i can not use the function of PointObject to get a CAJoint info.
