StartTime is initialized to the system time at the time Java 3D starts
up. If you want a behavior to start up at some point in the future,
the easiest way is to either change the start time:
alpha.setStartTime(System.currentTimeMillis()+1000);
or use the trigger time (although we just discovered a bug in setting
the trigger time--unless you set the start time or phase delay *after*
the trigger time it won't work):
alpha.setTriggerTime(1000)
alpha.setStartTime(System.currentTimeMillis());
either way, you need to set the Alpha's loopCount after setting the new
start and/or trigger time. For example, to run the Alpha once:
alpha.setLoopCount(1);
Btw, using the trigger time is more convenient if you have multiple
behaviors that you want to start at different points after the current
time:
currentTime = System.currentTimeMillis();
alpha1.setTriggerTime(2000);
alpha1.setStartTime(currentTime);
alpha1.setLoopCount(1);
alpha2.setTriggerTime(1500);
alpha2.setStartTime(currentTime);
alpha2.setLoopCount(1);
...
Hope this helps.

>> Alpha alpha=new Alpha(1,4000);

>> // adjust to System Time
>> alpha.setStartTime(0);
>> // start it one second in the future
>> alpha.setTriggerTime(System.currentTimeMillis()+1000);
