Hi everyone,

I made a simple program firing laser beam to enemy vehicle.
Laser beam is implemented using pfDCS -> pfClone -> pfAddChild.
When a beam hits enemy vehicle, then it is pfRemoveChilded.
It was successful, but when the beam disappears, the scene stopped
for about 0.2~0.3 second.

Now my questions :
1) Is pfRemoveChild so complex job?

2) If it is, is it reasonable to implement the beams using pfDCS ->
pfSwitch -> pfClone and pfAddChild at the beginning of the program,
and only manipulating pfSwitch when a beam fires or hits?

3) 2)'s approach has a problem that we must know the maximum number of
beam to be used. Is there other dynamic allocating and not-so-slow method?

Thanks in advance.
