@chuanzhen thank you, is work : )

hi，
I m confuse about if any way check deformcache dirty？ baseobject:: IsDirty() not working properly, it always return true. I look for answers in forums, only a very old answer is caculate all points pos sum and compare , some times it is too slow to work. so , is there any way to check deformcache dirty better?
hope your help.

@s_bach Oh, i miss a important part, thank you!

hi,
I m sorry to ask such basic questions, i m confuse about where to find lib_geom.h? such functions Geometry Utility Manual can't be find in my porject.

@s_bach Thank you!

hi,
i am confuse about how to add PRIORITY in ObjectData like Skin and Hair object ? show in basic tab?
and how to connect PRIORITY to ObjectData::Execute()? i try to use ObjectData::AddToExecute(), it work but not same as ExpressionTag, it will execute when i move cursor or other action, even execute after i closed objectplugin. it is strange. if any way execute ObjectData::Execute() like ExpressionTag do ?
hope your help!

@m_adam thank you for your answer from the code, it similar to what i already try, but this way looks like not a perfect solution. actually after read most c4d gui sdk and write some examples, i think maybe c4d should update gui model? sometimes it not flexible. just my personal thoughts, don't mind : ) expect python 3.x and pyside2 coming : )

@m_adam actually i want get my QuickTabCustomGui String count and name str，also reset ，but in Python sdk， only have appendstring() and ClearStrings()，so，i think maybe i can get the cutomgui data (basecontainer or other )and reset data by myself?

@r_gigante thank you for your answer，i m misunderstand what it means. And is there any way to get and reset customgui data? return a basecontainer and reset setting，looks like node.setparameter( )?

Hi，
i am confuse about BaseCustomGui.GetData(), my_QuickTabCustomGui.GetData() always return None and SetData() always return False, anyone could tell me how to use it?
hope yout help!

hi，
how to set DTYPE_VECTOR4D value use 'node.SetParameter'? i test vector4d list dict tuple, all show 'TypeError: could not convert 'xxx'' .this is my code:

cid = c4d.DescID(c4d.DescLevel(Dynamic_ID.V4D, c4d.DTYPE_VECTOR4D, 0))
node.SetParameter(cid, c4d.Vector4d(1, 2, 3, 4), c4d.DESCFLAGS_SET_NONE)

hope your help!

@m_adam oh，i miss this reason，thank you : )

hi,
i write a GUI and use mouse left to refresh GeUserarea , mouse right stop refresh. Unfortunately, when click mouser left, it crash. Somebody can tell me what I did wrong ？ this is my code.
Hope your help!

import c4d
from c4d import gui

class MyArea(gui.GeUserArea):
    def __init__(self) :
        self.leftclick = False

    def GetMinSize(self) :
        return (600, 500)

    def DrawMsg(self,x1, y1, x2, y2, msg):
        self.DrawSetPen(  c4d.Vector(.21) )
        self.DrawRectangle(x1, y1, x2, y2)

    def Message(self, msg, result):
        if msg.GetId():
            if self.leftclick:
                self.Redraw()
        return c4d.gui.GeUserArea.Message(self, msg, result)
    
    def InputEvent(self, msg) :
        if msg[c4d.BFM_INPUT_DEVICE] == c4d.BFM_INPUT_MOUSE:
            if msg[c4d.BFM_INPUT_CHANNEL] == c4d.BFM_INPUT_MOUSELEFT:
                self.leftclick = True
            if msg[c4d.BFM_INPUT_CHANNEL] == c4d.BFM_INPUT_MOUSERIGHT:
                self.leftclick = False
        return True

class Dialog(gui.GeDialog):
    def __init__(self, area) :
        self.area = area

    def CreateLayout(self) :
        self.AddUserArea(10010, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT)
        self.AttachUserArea(self.area, 10010)
        return True

def main():
    area = MyArea()
    MyDialog = Dialog(area)

    MyDialog.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE)

if __name__ == "__main__":
    main()

@r_gigante Thank you for your answer! it s all fine : )

@C4DS maybe use scenehook detect tool switch, and trigger tool "messgae" to free mybaseobject is a better way ?it can avoid the crash,and tool also work normally

unsafe way , just use "try catch(...)",skip error, if any better solution?

@C4DS thank you for your answer.follow your answer, i think if i can detect currect project close, the problem will be solve, could your tell me how to detect currect project close in toolplugin or scenehook? hope your help : )

hi，
i write a toolplugin, alloc a baseobject in InitTool() ,the baseobject pointer is toolplugin private member. free baseobject in FreeTool .
it works fine when switch tool .but when i close cinema 4d, myplugin will be crash and show this ,
i thought maybe cinema 4d free all object auto when close(i know it will not case crash,but just try)? so i use "if(myobject != nullptr)"check if free baseobject,but it unuseful, crash again. Where did I go wrong?
hope your help!

class mytool : public ToolData
{
   ......
private:
  BaseObject* myobject;
}

Bool mytool::InitTool(BaseDocument * doc, BaseContainer & data, BaseThread * bt)
{
  this->myobject = BaseObject::Alloc(Onull);
  doc->InsertObject(myobject,  nullptr,  false);
  return true;
}

void mytool::FreeTool(BaseDocument * doc, BaseContainer & data)
{
   BaseObject::Free(myobject);
}

@m_magalhaes thank you : ) : ) : )

@m_magalhaes i am not use scenehook before，i will see how to use it，thank you for your help
