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)
