你好朋友
我的编程和英语很差。对不起！
i 想要kinect只显示一个人骨架

请编辑代码以解决我的问题
谢谢
你需要做的是：
1）第一次看到你想在代码中跟踪的骨架时，将骨架TrackingId捕获到整数变量并存储它。 对于下面的代码，我有一个名为PlayerId的变量，我将变量存储在这里：
PlayerId = skeletonFrame.TrackingId;
2）下次你想通过其的trackingID获取骨架时，请使用此选择代码
&NBSP; &NBSP; &NBSP; &NBSP; using（SkeletonFrame skeletonFrameData = e.OpenSkeletonFrame（））
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; {
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; if（skeletonFrameData == null）
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; {
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;返回;
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; }
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; var allSkeletons = new Skeleton [skeletonFrameData.SkeletonArrayLength];
&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; skeletonFrameData.CopySkeletonDataTo（allSkeletons）;

please edit code to solve my problem
thanks
What you need to do is this:
1) The first time you see the skeleton you want to track in your code, capture the skeleton TrackingId into an integer variable and store it. In the case of the code below, I have a variable called PlayerId where I store the variable like this:
PlayerId = skeletonFrame.TrackingId;
2) The next time you want to get that skeleton by its trackingID use this selection code
using (SkeletonFrame skeletonFrameData = e.OpenSkeletonFrame())
{
if (skeletonFrameData == null)
{
return;
}
var allSkeletons = new Skeleton[skeletonFrameData.SkeletonArrayLength];
skeletonFrameData.CopySkeletonDataTo(allSkeletons);
var sd = (from s in allSkeletons
where s.TrackingState == SkeletonTrackingState.Tracked && s.TrackingId == PlayerId
select s).FirstOrDefault();
if (sd != null)
{... Do whatever you like
}
}
Hope this helps you out.
