Hello all,
I'm trying to add userdata to a custom object through the sdk, I've looked at DynamicDescription, but have no idea on how to setup the whole thing.
please help. -

Is this custom object your plugin? If so, you don't even need userdata - just add GetDDescription() to your ObjectData class and add the dynamic data/types there.
The basic way this works is that you fill in the static description - description->LoadDescription(node->GetType()). You then add dynamic ones by setting up the datatype, a container with description configuration parameters, and calling description->SetParameter();
Here is a short example (probably not the best example, but a start to understanding) :
// NodeData.GetDDescription - Descriptions and Parameters //*---------------------------------------------------------------------------* Bool IPPCamFrame::GetDDescription(GeListNode* node, Description* description, LONG& flags) //*---------------------------------------------------------------------------* { if (!(node && description)) return FALSE; // Load static descriptions first (!) if (!description->LoadDescription(node->GetType())) return FALSE; // Prepare data BaseDocument* doc = node->GetDocument(); if (!doc) return FALSE; BaseTag* tag = static_cast<BaseTag*>(node); if (!tag) return FALSE; BaseContainer* tbc = tag->GetDataInstance(); if (!tbc) return FALSE; foListBC.FlushAll(); bpListBC.FlushAll(); foListBC.SetString(0L, "- NONE -"); bpListBC.SetString(0L, "- NONE -"); foIndex = 1L; bpIndex = 1L; foSelect = tbc->GetLong(IPPCAMFRAME_FOSELECT); bpSelect = tbc->GetLong(IPPCAMFRAME_BPSELECT); // Catalog all iPP Figures in Document CatalogIPPFigures(doc->GetFirstObject()); // Update Drop-down lists foComboBC.SetContainer(DESC_CYCLE, foListBC); bpComboBC.SetContainer(DESC_CYCLE, bpListBC); tbc->SetLong(IPPCAMFRAME_FOCOMBO, foSelect); tbc->SetLong(IPPCAMFRAME_BPCOMBO, bpSelect); // Add the dynamic descriptions for display in the A.M. // The first arg is the dynamic ID, the second the configuration container, the last the parent GROUP under which the description is added if (!description->SetParameter(DescLevel(IPPCAMFRAME_FOCOMBO,DTYPE_LONG,0), foComboBC, DescID(ID_TAGPROPERTIES))) return FALSE; if (!description->SetParameter(DescLevel(IPPCAMFRAME_BPCOMBO,DTYPE_LONG,0), bpComboBC, DescID(ID_TAGPROPERTIES))) return FALSE; // Set flags: the first flags should always appear when successfull flags |= DESCFLAGS_DESC_LOADED|DESCFLAGS_DESC_RECURSIONLOCK; // This MUST BE CALLED! return SUPER::GetDDescription(node,description,flags); } -

thanks kuroyume0161 I'm a newbie at this stuff.
I have this working the node is created and I can see it in the property inspector of the object, except that I cannot set the actual string data.
maybe I'm using the wrong tag id? CUSTOMGUI_STRINGthe reason I'm using the userdata is because I won't be able to retrieve the data from this object with coffee.
so now the question is how do I set the actual string data?
thanks
Bool MyObject::Init(GeListNode *node) { BaseObject *op = (BaseObject* )node; BaseContainer *data = op->GetDataInstance(); DynamicDescription* ddesc = op->GetDynamicDescription(); BaseContainer bc; bc.SetString(DESC_NAME, "AI Map Info"); bc.SetString(DESC_SHORT_NAME, "AI Map Info"); bc.SetLong(DESC_CUSTOMGUI, CUSTOMGUI_STRINGMULTI); bc.SetString(CUSTOMGUI_STRING, "test string data"); DescID id = ddesc->Alloc(bc); ddesc->Set(id, bc); return TRUE; } -

If you are doing this in Init() why can't you just use a static description in the .h and .res files? Then you could set the string and get it using whatever (including COFFEE).
But if it is truly a dynamic description, doing it in Init() this way will not work. It must be done in GetDDescription().
The gui type for a text edit is CUSTOMGUI_STRING. But there is more to this. The way you are doing it (which is much more work if a static description), you would need to do this as well:
BaseContainer bc = GetCustomDataTypeDefault(DTYPE_STRING); bc.SetString(DESC_NAME, "AI Map Info"); bc.SetString(DESC_SHORT_NAME, "AI Map Info"); bc.SetLong(DESC_CUSTOMGUI, CUSTOMGUI_STRING); Description* desription; op->GetDescription(description, 0L); // This adds the description element to the Description description->SetParameter(DescLevel(??,DTYPE_STRING,0),bc,DESC_ROOT);The ?? is because you MUST set an ID value (LONG) for the description element that is unique for this node. The static ones are usually defined in the plugin object header (Omyplugin.h or Tmyplugin.h). That is how you access the description resource - and it is the ONLY way. Cinema 4D runs on IDs - and for descriptions, it lives off of them.
To set the actual description value, you need to get the BaseContainer for the node object (op) and set using that:
BaseContainer* obc = op->GetDataInstance(); obc->SetString(??, "test string data");Do the same to get the value:
String str = obc->GetString(??); -

I got it now that's what I needed
I'll try to move the description stuff to the .h file as you suggested, I may come back later with more questionsthanks again!
