Update question regarding ControlP5 knob! Newbie to java!

Hello!

I have just started programming in Processing and Object oriented programming. Until now I have used only embedded C programming.

My problem is regarding the ControlP5 library.

In the next piece of code the knob I am creating is not updating the value. I want to graphically show the value of the shoulder angle in the knob.
2. import SimpleOpenNI.*;
3. import controlP5.*;
5. SimpleOpenNI kinect;
7. ControlP5 cp5;
8. Knob myKnobA;
10. void setup()
11. {
12. kinect = new SimpleOpenNI(this);
13. kinect.enableDepth();
14. kinect.enableUser(SimpleOpenNI.SKEL_PROFILE_ALL);
15. kinect.setMirror(true);
17. cp5 = new ControlP5(this);
19. myKnobA = cp5.addKnob("knob")
20. .setRange(0,255)
21. .setValue(50)
22. .setPosition(700,70)
23. .setRadius(50)
24. .setDragDirection(Knob.VERTICAL)
25. ;
27. size(1024,768);
28. fill(255,0,0);
29. }
30. void draw()
31. {
32. kinect.update();
33. image(kinect.depthImage(),0,0);
35. IntVector userList = new IntVector();
37. kinect.getUsers(userList);
39. if(userList.size()>0)
40. {
41. int userId = userList.get(0);
42. if(kinect.isTrackingSkeleton(userId))
43. {
44. PVector rightHand = new PVector();
45. kinect.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_RIGHT_HAND,rightHand);
46. PVector convertedRightHand = new PVector(rightHand.x, rightHand.y);//convert to 2d
48. PVector rightElbow = new PVector();
49. kinect.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_RIGHT_ELBOW,rightElbow);
50. PVector convertedRightElbow = new PVector(rightElbow.x, rightElbow.y);//convert to 2d
52. PVector rightShoulder = new PVector();
53. kinect.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_RIGHT_SHOULDER,rightShoulder);
54. PVector convertedRightShoulder = new PVector(rightShoulder.x, rightShoulder.y);//convert to 2d
56. PVector rightHip = new PVector();
57. kinect.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_RIGHT_HIP,rightHip);
58. PVector convertedRightHip = new PVector(rightHip.x, rightHip.y);//convert to 2d
60. PVector torsoOrientation = PVector.sub(convertedRightShoulder, convertedRightHip);
61. PVector upperArmOrientation = PVector.sub(convertedRightElbow,convertedRightShoulder);
63. //calculez unghiurile
64. float shoulderAngle = angleOf(convertedRightElbow, convertedRightShoulder, torsoOrientation);
65. float elbowAngle = angleOf(convertedRightHand, convertedRightElbow, upperArmOrientation);
67. float convertedShoulderAngle = map(shoulderAngle,0,180,0,255);
68. myKnobA.setValue(convertedShoulderAngle);
70. //printez ce vreau
71. fill(255,0,0);
72. scale(3);
73. text("shoulder: "+ int(shoulderAngle)+" elbow: "+ int(elbowAngle)+" convertedShoulder: "+int(convertedShoulderAngle),20,20);
75. }
76. }
77. }
79. float angleOf(PVector one, PVector two, PVector axis)
80. {
81. PVector limb = PVector.sub(two, one);
82. return degrees(PVector.angleBetween(limb, axis));
83. }
84. void onNewUser(int userId)
85. {
86. println("start pose detection");
87. kinect.startPoseDetection("Psi",userId);
88. }
89. void onEndCalibration(int userId, boolean successful)
90. {
91. if(successful)
92. {
93. println("User calibrated!!!");
94. kinect.startTrackingSkeleton(userId);
95. }
96. else
97. {
98. println("Failed to calibrate user!!");
99. kinect.startPoseDetection("Psi", userId);
100. }
101. }
102. void onStartPose(String pose, int userId)
103. {
104. println("Started pose for user.");
105. kinect.stopPoseDetection(userId);
106. kinect.requestCalibrationSkeleton(userId,true);
107. }
On line 68 I am calling the myKnobA.setValue(); function and at the end it seems that it does not update the value.
For verification that the value convertedShoulderAngle is updated I am displaing it on the screen and it does update. Only the function setValue() is not called.

If more information is needed I would provide it.

Thanks in advance!

Problem adding Processing library.

What I have done until now:

- downloaded the library

- unzipped the library

- copied the library in the root folder of processing and in a folder created by me in the sketch folder.

- Processing 1.5.1 was closed when I tried to do this and when I finished I started it again.

When I am looking in the sketch menu at import library the library is not there.

Is this the correct way to go? Should there be any steps to go?

Thank you!

Cristian
