Hi,I'm working on an object-plugin. I have implemented the method Command, but it seems it doesn't get called. Here is my method:
Bool MyPluginData::Command(Int32 id, const BaseContainer &msg)
{
if (id == HIPNULLPTR_POS_Y)
{
GePrint("The slider is pressed!");
}return true;
}Did I do something wrong here? Or did I simply forget something?
I've looked for hours on the internet, in the SDK, but still found no answer.Thanks for your help and time!

Mainly only buttons really trigger Command(). For other controls, you need to use Message().

And actually Command() is not a method of the ObjectData class, but GeDialog. If you want to notice
when a value was changed, override Message() and catch the MSG_DESCRIPTION_* message that
matches your needs.Best

Hi,
Well, that did it, especially the MSG_DESCRIPTION. With my slider I needed the MSG_DESCRIPTION_CHECKUPDATE inside Message.

Well, it worked when I had a simple GePrint. Now with some additional methods it doesn't work anymore.
Here is my code in Message:if (type == MSG_DESCRIPTION_CHECKUPDATE)
{
BaseObject* op = (BaseObject* )node;
BaseDocument* doc = (BaseDocument* )data;
EditHipNullptr(op, doc);
GePrint("The slider is pressed! - CheckUpdate");
}And the code from EditHipNullptr:
BaseObject* CharacterCreatorData::EditHipNullptr(BaseObject* op, BaseDocument* doc)
{
BaseObject* hipNullPtr = doc->SearchObject("Hip_Nullptr");
BaseContainer* bb = op->GetDataInstance();
hipNullPtr->SetRelPos(Vector(0, bb->GetInt32(HIPNULLPTR_POS_Y), 0));
hipNullPtr->Message(MSG_UPDATE);
return hipNullPtr;
}When I change the slider in Cinema 4D, the application doesn't respond anymore.
Does somebody have an idea what could be the problem here?Greetings,

Hello,
the data of MSG_DESCRIPTION_CHECKUPDATE is not a BaseDocument but of the type DescriptionCheckUpdate. In that structure you will find a pointer to the document.
Also, you don't have any nullptr-checks in your code, so when SearchObject() fails it must crash.
Best wishes,

Hi Sebastian,
That did it! Thank you very much!
I also changed my method for nullptr-checks.
You can surely mark this as closed now!Greetings,
