}
Text retrieval:
const char *StudioModel::GetKeyValueText( int iSequence )
{
CStudioHdr *pStudioHdr = GetStudioHdr();
return Studio_GetKeyValueText( pStudioHdr, iSequence );
}
And implementation:
const char *Studio_GetKeyValueText( const CStudioHdr *pStudioHdr, int
iSequence )
{
if (pStudioHdr && pStudioHdr->SequencesAvailable())
{
if (iSequence >= 0 && iSequence <
pStudioHdr->GetNumSeq())
{
return pStudioHdr->pSeqdesc( iSequence
).KeyValueText();
}
}
return NULL;
}
YMMV...

Subject: [hlcoders] Animation timing tag extraction
Hi,
I am trying to extract the timing tag information from Source gestures.
(Timing tags are the little "apex", "accent", etc. tags you see when you
add a gesture to a scene in Face Poser.)
It seems like most of the gestures, ie Alyx's "A_g_wave" have related
gestures named A_g_waveapexArms, A_g_waveloopSpine. Since the number of
frames in "A_g_wave" tell how long the gesture is, I thought that the
framecount of A_g_waveloopspine et. al. would give me the timing tag
information. Unfortunately, that doesn't seem to be the case.
(This seems to give the right timing for the first tag, but not the
later ones.) I also tried seeing if the tags were implemented as
animation events, but that doesn't seem to be the case either.
Obviously there is some way to get this information, because FacePoser
is doing it, but I don't know how. And I don't think any of the code we
have access to extracts that information. Any ideas?
Also, if anyone else is ever interested in automatically generating
scenes for Half-Life 2, let me know. We have a bunch of Python code
that generates scenes, and are building a corpus with all the existing
Source scenes parsed into structures with associated speech timing
information, closed captioning, etc.
Thanks for any help,
Nate
