ROFL
Sorry.
The calls that you have in the other thread are all you need:
IF
phentgetvelocity(my, temp, nullvector)
THEN
1)
my is the entity you are sampling (in this case MY entity)
2)
temp will be set as the Velocity Vector upon function execution
3)
nullvector will mean that you are sampling in at (0,0,0) in the entity, which "should" be the center of the object you are sampling.
Since you are doing balls for you pachinko game (I think?

), make absolutly positively sure that (0,0,0) is the center of the ball. That way, since you have set vecpointlocal=nullvector, you are sampling the center and temp will ONLY be the linear (straight line) velocity or...
temp.x=velocity in the global x direction (east/west)
temp.y=velocity in the global y direction (north/south)
temp.z=velocity in the global z direction (sky/ground)
and I "think" all values will be in quant/frame
