Hello,
you cannot cast the BaseTag pointer into your plugin class.
Your plugin class is based on TagData which itself is based on NodeData. So you must get the pointer to the NodeData instance which represents your plugin instance.
This pointer is obtained with GetNodeData().
See Basic Classes and Plugin Classes and NodeData for an example.
In your code, you should also check if the first tag is really your tag and not any other tag.

Hello,
there is no simple function that returns the merged result of all objects from a generator's cache.
You simply have to get the meshes from the cache and merge them into a single mesh yourself. And, of course, also merge normals, UVs etc. as needed.

Hello,
ParallelFor::Dynamic() is a utility that manages the creation and execution of jobs (see Jobs Manual) automatically. Typically one should use ParallelFor::Dynamic(); ParallelFor::Static() is only needed for rare, specific cases.
You find an example for "assembly" in the second example on the Parallel Manual page. The "finalize" stage is called synchronously after all jobs have finished to collect and connect all data created. For that, a local data structure based on maxon::ParallelFor::BreakContext is needed.

Hello,
you find information on plugin migration in the C++ documentation:
As you see, MPThreadPool was removed in R20. Instead, developers should use the new maxon::ParallelFor for parallelization.
You also find an example in the cinema4dsdk: menutest.cpp

Hello,
it seems you just write the name of the last track into your user data field:
obj[c4d.ID_USERDATA,19] = trak.GetName()
Since you do not extend that string, it can only show one name.

Hello,
are you sure the indentation of your code is correct? Do you call
track = track.GetNext()
at the end of your loop?
What is the context of your code? Are you calling it whining a script or a Python Tag? Please post the full code you are actually using.
If a "while" loop is not suitable, you could also use GetCTracks() to get a list of all the tracks.
tracks = op.GetCTracks()
for track in tracks:
print(track.GetName())

Sebastian
Well, you indentation is off. And you are missing
track = track.GetNext()
at the end.
Besides that, this should work:
track = op.GetFirstCTrack()
while track is not None:
print(track.GetName())
start = track[c4d.CID_SOUND_START]
# get length
# length is stored as a string; need to convert it to int
length = track[c4d.CID_SOUND_LENGTH]
length = length[:-2]
length = int(float(length))
fps = doc.GetFps()
end = start + c4d.BaseTime(length, fps)
# check if the current frame is within the range of the sound clip
curTime = doc.GetTime()
if curTime >= start and curTime < end:
print("Uses Track: " + track.GetName())
else:
print("no hit")
track = track.GetNext()
I strongly suggest to get familiar with the basics of Python first.

Hello,
the tracks of an object are stored in a list. You can access the first track using GetFirstCTrack(). Then you can loop over all tracks with an ordinary while() loop and GetNext().
track = op.GetFirstCTrack()
while track is not None:
print(track.GetName())
track = track.GetNext()
See also the example in the C++ CTrack documentation.

Hello,
"soundwaves" are organized as animation tracks (CTrack) referencing sound files.
You can check if the current frame is in the range of a given CTrack. This range is the result of the start position of the track plus the length of the sound file.
The length of the sound file can be obtained from the track, but the value is stored as a string. So you would have to convert that into a time value (BaseTime).
Such a check can look like this:
start = track[c4d.CID_SOUND_START]
# get length
# length is stored as a string; need to convert it to int
length = track[c4d.CID_SOUND_LENGTH]
length = length[:-2]
length = int(float(length))
fps = doc.GetFps()
end = start + c4d.BaseTime(length, fps)
# check if the current frame is within the range of the sound clip
curTime = doc.GetTime()
if curTime >= start and curTime < end:
print("Uses Track: " + track.GetName())
else:
print("no hit")
Of course, you have to loop over all sound tracks associated with a given object.
You also find information on CTracks in the C++ documentation: CTrack Manual.

Hello,
this is a bug.
So far, the NAME attribute has only been used to re-name solutions, but not plugins. It is better to not use the NAME attribute with plugins.
