Hi i want to move that female_arm smoothly.
if minus sigal input from UDP, i want to move forearm from 0 to -90 degee.
so i have been coding this.
please modify my code.

def update():
global n1,n2
n1 -= 1
n2 += 1
data = ReceiveData()
if data:
udp = struct.unpack(">d", data[0])[0]
print udp
if 0 > udp :
Euler = Forearm.getEuler(viz.AVATAR_WORLD)
Forearm.setEuler([0,0,n1])
#Forearm.setEuler([0,viz.elapsed(),-1],viz.REL_LOCAL)
UpperArm.setEuler(0, -30, -80)
