@ferdinand Thank you very much for your reply

Hello colleagues, I used C++ to write the C4D S26 plugin on Windows 10. Swap the positions of 2 and 10 in the Object Manager. I cannot find the relevant API.

BaseDocument* doc = GetActiveDocument();
Int32 count = selection->GetCount();
AutoAlloc<AtomArray> selection;
doc->GetActiveObjects(selection, GETACTIVEOBJECTFLAGS::CHILDREN);
BaseObject* obj_2 = static_cast<BaseObject*>(selection->GetIndex(count - obj_10));
BaseObject* obj_10 = static_cast<BaseObject*>(selection->GetIndex(count - obj_2));

What should we do next？Thanks in advance!

Hello colleagues, I used C++ to write the C4D S26 plugin on Windows 10, This is an animation, How to obtain the color of each ball in each frame, Colors are set in a Linear Field.Thanks in advance!

Hello colleagues, I used C++ to write the C4D S26 plugin on Windows 10, How can I modify the index of these cubes.what should I do?

@i_mazlov thank you very much

@i_mazlov Thanks for your explanation. How to use code to execute the "Select Connected" command and loop through all points. I have obtained all the points now, but I don't know how to execute the "Select Connected" command for each point

BaseObject* obj = doc->GetActiveObject();
PointObject* pointObj = static_cast<PointObject*>(obj);
Int32 pointCount = pointObj->GetPointCount();		
Vector* points = pointObj->GetPointW();

@i_mazlov Or is there a way to preserve the animation after using MCOMMAND_EXPLODESEGMENTS

Thanks @i_mazlov I wrote a plugin that would read the coordinates of every sphere in every frame and then output, and get all frame coordinates of all spheres to the user

Hello colleagues, I used C++ to write the C4D S26 plugin on Windows 10, I import .abc and want to explode this file, but I found using SendModelingCommand()that the sphere animation disappeared, what should I do?

BaseDocument* doc = GetActiveDocument();
BaseObject* activeObject = doc->GetActiveObject();
if (!activeObject)
	return break;
ModelingCommandData mcd;
mcd.doc = doc;
mcd.op = activeObject;
const bool result = SendModelingCommand(MCOMMAND_EXPLODESEGMENTS, mcd);
if(result)
{
	EventAdd();
}

Although I got all the spheres, all the sphere animation was lost, Thanks in advance!
