Thanks for the response.
DESC_GUIOPEN works having the twirl down open by default. What I'm looking for is the ability to modify whether or not it is actively open based on controls by the user. For example if "Angle Threshold" is greater than 90 degrees than have it twirled down, otherwise have it closed.

Hi.
I am currently working on an object plugin that would utilize Takes for a user to be able to quickly iterate through different potential versions of their scene. I've looked through the sdk and the different manuals that are available and I believe I understand the processes required.
My issue comes in with the amount of time it take Cinema to run my plugin in regards to the creation of the Takes and if this is just the time that it takes to create them.
I created a simple scene with a hundred objects underneath my plugin. With the code below I create a Take and assign a layer to each of the child objects. For time testing I create an additional 500 Takes using the first Take as the cloneFrom inside AddTake. This isn't a final version of my code just a test example.
The code is executed on a button press.
case idRunTakes:
{
TakeData* takeData = doc->GetTakeData();
if (!takeData)
return TRUE;
LayerObject *hideLayer = LayerObject::Alloc();
const Vector hsv = Vector(1.0, 0, 0);
const Vector rgb = HSVToRGB(hsv);
newTakeTime = 0;
settingTakeTime = 0;
LayerData newdata;
newdata.color = rgb;
newdata.solo = FALSE;
newdata.view = FALSE;
newdata.render = FALSE;
newdata.manager = TRUE;
newdata.locked = FALSE;
newdata.generators = FALSE;
newdata.deformers = FALSE;
newdata.expressions = FALSE;
newdata.animation = FALSE;
newdata.xref = TRUE;
hideLayer->SetLayerData(doc, newdata);
hideLayer->SetName("Hide Layer"_s);
GeListHead* layerList = NULL;
layerList = doc->GetLayerObjectRoot();
layerList->InsertLast(hideLayer);
maxon::BaseArray<BaseObject*> childObjArray;
GatherAllChildObjects(splineObj->GetDown(), childObjArray);
DescID aliasLinkDId = DescLevel(ID_LAYER_LINK, DA_ALIASLINK, 0);
GeData setData;
setData.SetBaseList2D((BaseList2D*)hideLayer);
Float createNewTakesTime = 0;
Float timeStart = 0;
Float loopTimeStart = GeGetMilliSeconds();
timeStart = GeGetMilliSeconds();
BaseTake* newTake = takeData->AddTake(String("Take " + String::IntToString(0)), nullptr, nullptr);
if (newTake == nullptr)
return TRUE;
createNewTakesTime = createNewTakesTime + GeGetMilliSeconds() - timeStart;
for (Int32 childObjIndex = 0; childObjIndex < childObjArray.GetCount(); childObjIndex++)
{
BaseOverride* overrideNode = newTake->FindOrAddOverrideParam(takeData, childObjArray[childObjIndex], aliasLinkDId, setData);
if (overrideNode == nullptr)
return TRUE;
childObjArray[childObjIndex]->SetLayerObject(hideLayer);
overrideNode->UpdateSceneNode(takeData, aliasLinkDId);
}
for (Int32 takeIndex = 1; takeIndex < 501; takeIndex++)
{
timeStart = GeGetMilliSeconds();
// This is the line taking up a lot of time
BaseTake* loopTake = takeData->AddTake(String("Take " + String::IntToString(takeIndex)), nullptr, newTake);
if (loopTake == nullptr)
return TRUE;
createNewTakesTime = createNewTakesTime + GeGetMilliSeconds() - timeStart;
}
ApplicationOutput("Take time " + String::FloatToString(createNewTakesTime) + " " + String::FloatToString(GeGetMilliSeconds() - loopTimeStart - createNewTakesTime));
break;
}
// Code for getting all of the child objects
void TakeCreatorPlugin::GatherAllChildObjects(BaseObject *childObject, maxon::BaseArray<BaseObject*> &objChildOfNullsArray)
{
if (childObject == nullptr)
return;
while (childObject)
{
objChildOfNullsArray.Append(childObject);
GatherAllChildObjects(childObject->GetDown(), objChildOfNullsArray);
childObject = childObject->GetNext();
}
}
Running the code in my test scene gives the following print out "Take time 1920.243 20.232". So most of the time my plugin is running is taken up by adding the takes into the document. Is this just the time that Cinema takes in this kind of circumstance to create the Takes or am I just missing a crucial step,
I've looked through the manuals in the sdk and tried to follow them.
I've also tried to create all of the Takes empty and add the Overrides to each one individually which increases the time that step takes which isn't desirable either.
Any help would be greatly appreciated.

Hi.
When working on a tag plugin I've recently been encountering a problem when I try to interact with Capsules, my plugin is meant to have parameters dropped onto it from the object it is attached to.
In my code I can properly receive the drag and drop operation and get the information from the parameter that was dropped onto it, the issue comes in when I try to determine which object the parameter came from.
When it comes to the Capsules in the object manager my code does not return the results that I am expecting when I try to verify that the parameters were dragged from the object that the tag is on.
The code below is a stripped down version of my drag and drop code.
Bool TagExample::Message(GeListNode* node, Int32 type, void* t_data)
{
BaseDocument* doc = node->GetDocument();
if (!doc)
return TRUE;
BaseTag* tag = static_cast<BaseTag*> (node);
if (!tag)
return TRUE;
if (type == MSG_DRAGANDDROP)
{
DragAndDrop* dnd = static_cast<DragAndDrop*>(t_data);
if (!dnd)
return TRUE;
if (dnd->type == DRAGTYPE_DESCID)
{
DescPropertyDragData* dndid = static_cast<DescPropertyDragData*>(dnd->data);
AutoAlloc<AtomArray> dndidarr;
dndid->arr->CopyTo(dndidarr);
if (dndidarr->GetCount() <= 0)
return TRUE;
BaseObject* tagObject = tag->GetObject();
if (!tagObject)
return TRUE;
BaseObject *draggedObject = (BaseObject*)dndidarr->GetIndex(0);
if (!draggedObject)
return TRUE;
if (draggedObject != tagObject)
ApplicationOutput("Do not equal");
else
ApplicationOutput("The objects equal")
return TRUE;
}
}
return true;
}
For some reason when I drag a parameter from a Neutron Cube, that my tag is on, onto my tag I don't get the expected result of the dragged object and the tag object equalling each other. If I do the same procedure on a regular Cube (Ocube) I am able to properly catch that the objects are one and the same. The same behavior is encountered with other Capsules.
I'm not very familiar with Capsules, is there a specific way that Capsules need to be interacted with in order to achieve the desired results?
Any help would be greatly appreciated.
John Terenece
Thanks for the response, it's all working properly now.
John Terenece
Thanks for the detailed response.
I was able to successfully compile and run the code you provided but I'm running into some weirdness when trying to drag different parameters onto the tag.
Thanks for the response.
I tried implementing the small example bit of code you gave into my own and I was unable to get it properly working. Heres the project file I'm working from that's just a trimmed down version of the sdk example (cinema4dsdk.zip).
Inside of the example.assets under modules I was able to successfully get it to compile but when I tried to do it inside of the cinema4dsdk module it would continuously give errors that I was missing various header files. When I followed the usual procedure to include the various header files requried I started getting errors inside of the header files themselves saying they were missing other files that they had included that I can't find on my computer.
This is the first time I'm encountering these kinds of errors so I'm not entirely sure if I'm missing something extremely simple.
And just to be clear with what I'm attempting to do is I want to be able to catch if a parameter dragged onto my tag is coming from the object that the tag is attached to. With an Ocube my code properly works, with a Neutron Cube my code will not tell me that the dragged parameter's object matches the tag's object.

Hi,
I'm working on a project that is made up of multiple tag plugins. What I'm trying to do is have the tags all separate in the list of Tags instead of under one folder.
Below I have a screenshot of the compiled base SDK for visual purposes.
So what I'm looking for is to have the three plugins inside of the "Cinema4dsdk Tags" dropdown not be inside of a submenu.
I know you can do this by compiling them all as separate projects but I would prefer to avoid going that route if there is an alternative.
Any help would be appreciated.
John Terenece
Thanks for the response.
I figured that something like this would be the case, will have to look into the options you mentioned.
John Terenece
Thanks for the detailed response.
I implemented the GeIsMainThread() into my code and that itself did not change any of the results I am getting which I would expect it to.
Running my code with a StartUndo and EndUndo results in this behavior StartEnd Undo.webm
I have tried the code without any AddUndo and this was the result No AddUndo.webm.
Sorry I wasn't clear in what I wanted the undos to do. As seen in both videos dropping one tag onto the other causes the dropped tag to move and the link field to change, what I am trying to do is have both of those being undone in a single undo so that the link field would be cleared and the dropped tag moved back to its original position.
I know that dragging a tag into the link field itself doesn't require an undo, that part of my code works perfectly fine.
John Terenece
Hi.
I am working on a tag plugin that will have a user drag & dropping another tag onto it, the dragged tag will then be set into a link field for use later. I successfully have the drag and drop working, my issue comes in when I try to implement undo functionality for the drag and drop.
With the code below (from the sdk) I have the tag only accepting tags of the same type as the plugin itself. After the drag and drop it takes two separate undos to successfully revert the link field to its previous state. I've tried the code below with the StartUndo/EndUndo and it always takes the two undos.
