Hi everybody,
it seems that keyframing I did in previous versions does not work with R10 anymore. Do you have any experience with it? I know, that the timeline/track/sequence things somehow changed.
But how can I set keyframes?
And: Where can I download SDK for R10. Isn't it ready.
Thanks for your help
Chris

Yes, track/sequence/keys are no longer represented by BaseTrack/BaseSequence/BaseKey - they are deprecated. You must now use CTrack/CCurve/CKey, CCurve being automatically added to the track.

The SDK itself is included with R10, but the SDK documentation still isn't ready it seems.

Thanks for the answer!
Has anybody a small samplecode for this?

Check out the Morphmixer example in the SDK, especially the static CreateKey function.

Hello Matthias,
have you already used the CreateKey function?
I transfered it to my plugin and I can complie, but
I don't know, what parameters I have to pass.
What is the Index? Is this ID_BASEOBJECT_POSITION for position?

What about the value. It is just a REAL. But a position is a vector.

Before, I used code I found here in the forum. I set it to the end.
Thanks
Chris
if(mybo)
{
  p = mybo->GetPos();
  val[0] = p.x;
  val[1] = p.y;
  val[2] = p.z;
}
else return FALSE;
for (ii=0; ii<3; ii++)
{
// check if track exists
descID = DescID(DescLevel(ID_BASEOBJECT_POSITION, 0, 0), DescLevel(VECTOR_X+ii, 0, 0));
track = mybo->FindTrack(descID);
if (!track)
{
  track = AllocValueTrack(mybo,descID); if (!track) return FALSE;
  mybo->InsertTrackLast(track);
}
// check for sequence
seq = NULL;
for (seq = track->GetFirstSequence(); seq; seq=seq->GetNext())
if (time>=seq->GetT1() && time<=seq->GetT2())
  break;
if (!seq)
{
  seq = track->AutoAddSequence(mydoc,time);
  if (!seq) return FALSE;
}
key = BaseKey::Alloc(seq->GetType()); if (!key) return FALSE;
av = GetKeyValue(key); if (!av) return FALSE;
av->value = val[ii];
key->SetTime(time);
seq->InsertKey(key);
}

Yeah ID_BASEOBJECT_POSITION is the ID for the position. Here is some sample code, it is the modified Morphmixer that records a hidden vector parameter. Remember that there are no sequences anymore and everything is now working with DescIDs.
