Joint Speed zero!?

[alex_f_2]

Hello, I am trying to get the speed of a hand joint in java, I defined the speed like this

float speed = new PXCMHandData.JointData().speed.x; 

when i print speed, I always get 0.0

Have you EnableJointSpeed in PXCMHandConfiguration?

[alex_f_2]

Yes, I did

int time=0;
PXCMHandData.JointType  JT = JointType.JOINT_CENTER;
PXCMHandData.JointSpeedType JST = JointSpeedType.JOINT_SPEED_ABSOLUTE;

handConfig.EnableJointSpeed( JT, JST, time);

Is it right like this??
