Hi,
I am fairly new to Performer, I couldn't set the values of any switches in
my scene, so I tried an example from the manual to make sure the error was
not in my code, and it still didn't work, I'm trying to fidn out what I am
doing wrong, any help is appreciated

 //
  float sCurrVal;
  int result;
  pfSwitch *sample_sw;
  pfSequence *explosion1_seq, *explosion2_seq;

  sample_sw = pfNewSwitch();
  explosion1_seq = pfNewSeq();
  explosion2_seq = pfNewSeq();

  pfAddChild(sample_sw, explosion1_seq);
  pfAddChild(sample_sw, explosion2_seq);

  result = pfGetNumChildren(sample_sw);
  fprintf(stderr,"switch has %d children\n",result);

  sCurrVal = pfGetSwitchVal(sample_sw);
  fprintf(stderr,"switchval = %f\n",sCurrVal);

  pfSwitchVal(sample_sw, 1); //set to 1
  sCurrVal = pfGetSwitchVal(sample_sw);
  fprintf(stderr,"switchval = %f\n",sCurrVal);
//
  The output I get is:
  switch has 2 children
  switchval = 0.000000
  switchval = 0.000000
