Hi !

How can I get the Animation Sequences for Bones ? (Cinema is quit complex )

I tried for test this:

BaseTrack* Track = doc->GetFirstTrack();
BaseSequence* Seq = Track->GetFirstSequence();
BaseKey* Key = Seq->GetFirstKey();
BaseList2D* Object = Key->GetObject();
String Name = Object->GetName();
GePrint(Name);

But i get an Exception ... NullPointer

Someone know the answer ?

Thanks

Like any programming practice, you should check for valid pointers before using them. There might not be a Track or Seq or Key or Object, any of which would return a Null pointer exception.

Never assume that they exist.

Hmm ur right, but ive made a Bone Animation Sequence

I hate it ... Mc Donalds ^^

Uhm, i tried now much, but i dont get the Animation Tracks I need them to save to Bone Animations (Which Bone, From Frame - To Frame, Frames).

I tried GetFirstTrack no success, i tried GetFirstRenderData no succes

Ive no Idea, how can i get these f**k data ?

I get crazy

I think I see your problem: BaseDocument doesn't have Tracks. The 'Document' is not animatable, only the objects, materials, tags. Just because it is an option for a GeList2D doesn't make it available.

You need to get your Tracks from the animated Objects.

From the Documentation:

_BaseTrack *GetFirstTrack(void)

Returns the first animation track of the object._

So, get your Document's Objects and get the Tracks from the Objects.

So you mean i should get the Animations (Keyframes from Bones) directly from the Object ?

Ok i will try, but i won't work. Yesterday I let Cinema Print all Names of the objects (with you printhistory / printchildren functions).
But the Names of the Bones wasn't listed ...

I Printed the Names without an If, i just Printed all Names. I tried with my own rekursion function but the same problem.

Here the rekursion (dunno this word on english ;)) function:

void PrintChildren(BaseObject *obj)
{
if(!obj)
return;

DoParse(obj);

PrintChildren(obj->GetDown());
     PrintChildren(obj->GetNext());
//     PrintChildren(obj->GetPred());
//     PrintChildren(obj->GetUp());
}

void PrintHierarchy(BaseDocument *doc)
{
if(!doc)
return;

BaseObject *obj = doc->GetFirstObject();
if(!obj)
return;

DoParse(obj);
PrintChildren(obj);
}

DoParse is my little Helper

It only makes Stuff like this:
if(Obj->GetType() == Opolygon)
{
HELPER_AddVertex(Obj);
}
...

Yes, get the Tracks from the Object. This code is from the MorphMixer.cpp example source that comes with the SDK. It doesn't get the animation info, but it should give you an idea of how to work through the existing animation info.

  
static Bool CreateKey(BaseDocument *doc, BaseObject *op, const BaseTime &time;, LONG index, Real value)  
{  
     // check if track exists  
     BaseTrack *track = op->FindTrack(DescLevel(index,DTYPE_REAL,0));  
     if (!track)  
     {  
          track = AllocValueTrack(op,DescLevel(index,DTYPE_REAL,0)); if (!track) return FALSE;  
          op->InsertTrackLast(track);  
     }  
  
     // check for sequence  
     BaseSequence *seq=NULL;  
     for (seq = track->GetFirstSequence(); seq; seq=seq->GetNext())  
          if (time>=seq->GetT1() && time<=seq->GetT2())  
               break;  
  
     if (!seq)  
     {  
          seq = track->AutoAddSequence(doc,time);   
          if (!seq) return FALSE;  
     }  
  
     BaseKey *key = BaseKey::Alloc(seq->GetType()); if (!key) return FALSE;  
     AnimValue *av = GetKeyValue(key); if (!av) return FALSE;  
  
     av->value = value;  
  
     key->SetTime(time);  
     seq->InsertKey(key);  
     return TRUE;  
}

And here is my working print hierarchy code:

  
// Print Hierarchy  
void PrintHierarchy(BaseDocument *doc)  
{  
     BaseObject *obj;  
     if (!(obj = doc->GetFirstObject())) return;  
     PrintChildren(obj);  
}  
// Print Children recursively  
void PrintChildren(BaseObject *obj)  
{  
     for (; obj; obj = obj->GetNext())  
     {  
          GePrint(obj->GetName());  
          if (obj->GetDown()) PrintChildren(obj->GetDown());  
     }  
}

One thing to mention, just to be sure: the objects MUST be in the document - added to document with doc->InsertObject(obj,...). Virtual objects (not added to any document) will not show up in a document's object hierarchy.

-Uhm ... i dont make the Models, the guy who makes it simply makes bones with vertexmaps and bones
Hmm ... i will test ur code.

// Edit

I have tested your code, it dont show bones 2 U said i must add to document but the Modeler only use standard bones from Cinema 4d

// Edit 2

Hey Rob, i found something out...
When I create a Bone then it shows it, when i make it a subentity of another object than not ?_?

Examples:
Single

->Bone Object
->Other Stuff

=> works

Subentry

->Other Stuff
-->Bone Object

=> dont work ?

Hi furbolg
I wrote this msg to you

Hi

I'm building an exporter plugin like you (at the moment it's exports vertices, averaged normals, uvws, and made some pre-calcs about volume shadows) so i think it's a good ideia to us if we could talk about that

Do you have ICQ or MSN?
My ICQ number: 35142180

Thx

i'm waiting your answer."
