Hi,
I have a c4d document ("doc"), I'm trying to load an other c4d document ("doc2"), retrieve the first object of doc2 insert this in "doc", and then close "doc2".

the equivalent in coffee :

>     f->AddLast("plugins");
>     f->AddLast("scene.c4d");

>           doc->InsertObject(newObject,NULL,NULL);

The file "scene.c4d" is in the plugin directory of Cinema4D folder.

I can not reproduce it in C++.

In C++, LoadDocument() returns the new document so you don't have to get it. Best to allocate and use an AliasTrans:

Thank you kuroyume0161 for your help but when I try your code it generate some errors :

Sorry I'm a beginner, I still sought in the SDK for a short time but I
found nothing to solve the problem. Thank you again.

I didn't fill in the FLAGS since you need to determine which ones to 'OR' together. You do have the SDK Help files, correct? Setting this argument to 0L should do.

BaseDocument* doc2 = LoadDocument(f, 0L, NULL);

Unlike COFFEE, C++ is a typed language. To convert from one type to another sometimes requires casting (depending upon the direction and extent of change). Since BaseObject is derived from C4DAtom (as are almost all C4D Base classes), just static cast:

objet = static_cast<BaseObject*>objet->GetClone(COPY_NO_ANIMATION, trans);
