基础：添加KinectManager 组件

1）局部关节获取（参考插件场景KinectOverlayDemo1）

要获取局部某一关节及其位置，添加脚本JointOverlayer即可，通过Tracked joint参数可以分别获取到相关关节位置以及坐标。

2）所有关节获取（参考插件场景KinectOverlayDemo2）

获取所有关节，可用脚本SkeletonOverlayer

也可参考如下代码

///

/// 通过index获取用户的关节，并在每个关节点放置cube ///

///
private void GetBodyJoints(int index)
{
if(GetDetected())
{
long userId = kinectManger.GetUserIdByIndex(index);

        int jointsCount = kinectManger.GetJointCount();

        if(!isJointsCreated)  
        {  
            for (int i = ; i < jointsCount; i++)  
            {  
                joints.Add(Instantiate(jointGo));  
            }  
            isJointsCreated = true;  
        }  
        else  
        {  
            for (int i = ; i < jointsCount; i++)  
            {  
               joints\[i\].transform.position = kinectManger.GetJointKinectPosition(userId,i);  
               joints\[i\].name = i.ToString();  
            }  
        }  
    }  
}

3）交互功能（参考插件场景KinectOverlayDemo3）

交互功能即为通过手势实现鼠标点击功能需要InteractionManager以及HandOverlayer脚本，通过HandOverlayer/InteractionManager脚本上的参数带texture的参数来实现抓取松开等样式

如果要把手的位置反应到UI上则需要特殊处理，因为我们获取的手的坐标单位为米，反应到unity中只是为数字（比如左手移动0.2m），但是如果分辨率为1920X1080，则手的移动0.2相对于分辨率来说几乎为零，所以需要通过UICamera.ViewportToWorldPoint来转化一下（或者   UICamera.ViewportToScreenPoint）下述脚本为在JointOverlayer中修改的update部分，通过获取手移动的box（范围），然后通过手实际位置转换成相对坐标，然后转化到实际分辨率下的位置。

void Update ()  
{  
    KinectManager manager = KinectManager.Instance;

    if(manager && manager.IsInitialized() && foregroundCamera)  
    {  
        //backgroundImage.renderer.material.mainTexture = manager.GetUsersClrTex();  
        if(backgroundImage && (backgroundImage.texture == null))  
        {  
            backgroundImage.texture = manager.GetUsersClrTex();  
        }

        // get the background rectangle (use the portrait background, if available)  
        Rect backgroundRect = foregroundCamera.pixelRect;  
        PortraitBackground portraitBack = PortraitBackground.Instance;

        if(portraitBack && portraitBack.enabled)  
        {  
            backgroundRect = portraitBack.GetBackgroundRect();  
        }

        // overlay the joint  
        int iJointIndex = (int)trackedJoint;

        if (manager.IsUserDetected())  
        {  
            for (int i = ; i < ; i++)  
            {  
                long userId = manager.GetUserIdByIndex(i);

                //manager.IsUserTracked(userId);

                if (manager.IsJointTracked(userId, iJointIndex))  
                {  
                    //MainFunController.theController.OnDebug("Joint tracked\\r\\n" + GetPara(manager));

                    overlayObject.gameObject.SetActive(true);  
                    Vector3 rightIboxRightBotBack = Vector3.zero, rightIboxRightTopFront = Vector3.zero, rightHandScreenPos = Vector3.zero;  
                    bool isrightIboxValid = false;  
                    isrightIboxValid = manager.GetRightHandInteractionBox(userId, ref rightIboxRightBotBack, ref rightIboxRightTopFront, isrightIboxValid);

                    if (isrightIboxValid && manager.GetJointTrackingState(userId, (int)KinectInterop.JointType.HandRight) != KinectInterop.TrackingState.NotTracked)  
                    {  
                        Vector3 rightHandPos = manager.GetJointPosition(userId, (int)KinectInterop.JointType.HandRight);

                        rightHandScreenPos.x = Mathf.Clamp01((rightHandPos.x - rightIboxRightBotBack.x) / (rightIboxRightTopFront.x - rightIboxRightBotBack.x));  
                        rightHandScreenPos.y = Mathf.Clamp01((rightHandPos.y - rightIboxRightBotBack.y) / (rightIboxRightTopFront.y - rightIboxRightBotBack.y));  
                        rightHandScreenPos.z = Mathf.Clamp01((rightIboxRightBotBack.z - rightHandPos.z) / (rightIboxRightBotBack.z - rightIboxRightTopFront.z));  
                    }

                    Vector3 cursorTargetPos = UICamera.ViewportToWorldPoint(rightHandScreenPos);

                    overlayObject.position = Vector2.Lerp(overlayObject.position, cursorTargetPos, 1f);  
                    break;  
                }  
                else  
                {  
                    overlayObject.gameObject.SetActive(false);  
                    //MainFunController.theController.OnDebug("Joint miss");  
                    //isFirstCatch = true;  
                    //CollisionEvent.theEvent.OnStop();  
                }  
            }  
        }  
        else  
        {  
            //debugText.text = "body miss";  
        }

    }  
}

注：应用时建议复制此脚本，并修改名称，然后做自己的修改
