How to access thinkin particles data channels correctly?

Aaron

Hi All,
There is thinking particles system and it has few named channels such as here:

 Float   [chan   5] DataChannelType    19 DataChannelName mass(Real)
 Float   [chan   6] DataChannelType    19 DataChannelName oldP(Real)
 Float   [chan   8] DataChannelType    19 DataChannelName pscale(Real)
 Float   [chan 10] DataChannelType    19 DataChannelName spriteuv(Real)
 Vector [chan   1] DataChannelType    23 DataChannelName Cd(Vector)

I get channel info using tps->DataChannelType(chan) and etc.
19 is DTYPE_REAL, 23 is DTYPE_VECTOR
But when I try to read the channel value per particle then it returns false and doesn't read the values. For example this request returns false:

  TP_MasterSystem* tps;
  Vector fval(0.0);
  tps->GetData(pid, channel, &fval, DTYPE_VECTOR);
// nothing is written in fval. I also tried to use GeData, but it didn't help

Other particle data such as tps->Transform(...), tps->Color(...), tps->Age(...) is returning relevant results.

Please, can someone show me a valid example of correct TP data channel access?

Cheers

Solved, it works this way:

Vector v(0.0);
tps->GetData(pid, channel, &v, ID_GV_VALUE_TYPE_VECTOR);
