Kinect2 KinectPV2 library skeleton tracking

I have been working with this code for a bit now and have been struggling to find what gives a specific x and y value for the points on joints or hands. I see that joints.getX() or joints.getY() does do this but it seems to get the values of all the joints and not just one.

this is the code /* Thomas Sanchez Lengeling. http://codigogenerativo.com/

Skeleton depth tracking example */

import java.util.ArrayList; import KinectPV2.KJoint; import KinectPV2.*;

KinectPV2 kinect; float r;

void setup() { size(512, 424, P3D);

kinect = new KinectPV2(this);

//Enables depth and Body tracking (mask image) kinect.enableDepthMaskImg(true); kinect.enableSkeletonDepthMap(true);

kinect.init(); }

void draw() { float r = 0; r = r+.1; background(0);

image(kinect.getDepthMaskImage(), 0, 0);

//get the skeletons as an Arraylist of KSkeletons ArrayList skeletonArray = kinect.getSkeletonDepthMap();

//individual joints for (int i = 0; i < skeletonArray.size(); i++) { KSkeleton skeleton = (KSkeleton) skeletonArray.get(i); //if the skeleton is being tracked compute the skleton joints if (skeleton.isTracked()) { KJoint[] joints = skeleton.getJoints();

  color col  = skeleton.getIndexColor();
  fill(col);
  stroke(col);

  drawBody(joints);
  drawHandState(joints[KinectPV2.JointType_HandRight]);
  drawHandState(joints[KinectPV2.JointType_HandLeft]);
}

}

fill(255, 0, 0); text(frameRate, 50, 50);
