Button not working when using NuitrackScripts

1

Hi guys! When I add “NuitrackScripts” in Folder “Prefabs”, my button is not working, although it was working properly before adding “NuitrackScripts”
Code:
private void OnGUI()
{
if (GUI.Button(new Rect(0, 10, 80, 20), “Click”))
{
save_excel();
}
}
public void save_excel()
{
if (File.Exists(filename))
{
File.Delete(filename);
}
TextWriter tw = new StreamWriter(filename, false);
tw.WriteLine(“Left Knee, Left Hip, Time”);
tw.Close();
tw = new StreamWriter(filename, true);
foreach (var knee in angle_Knee)
{
foreach (var hip in angle_Hip)
{
foreach (var time in data_time)
{
tw.Write(knee + “,” + hip + “,” + time);
tw.Close();
}
}
}
Debug.Log(“Ok!”);
}

Hi!

This problem is not related to Nuitrack, the problem is in your code.
I changed your example a little so that it works correctly, here’s a look:

private void OnGUI()
{
    if (GUI.Button(new Rect(0, 10, 80, 20), "Click"))
    {
        save_excel();
    }
}
public void save_excel()
{
    if (File.Exists(filename))
    {
        File.Delete(filename);
    }

    using (TextWriter tw = new StreamWriter(filename, false))
    {
        tw.WriteLine("Left Knee, Left Hip, Time");

        foreach (var knee in angle_Knee)
        {
            foreach (var hip in angle_Hip)
            {
                foreach (var time in data_time)
                {
                    tw.WriteLine(knee + "," + hip + "," + time);
                }
            }
        }
    }
    Debug.Log("Ok!");
}

I used “using”, as it is more correct and stable than closing the file write stream manually.

You closed the write stream in a nested loop (tw.Close()). because of this, writing to the file failed on the next iteration.

I assume that this error did not occur without Nuitrack, due to the fact that there was no data to write, and none of the loops were executed.

Thanks for your answer. But I try to add some data and this problem is still the same. I think it lies elsewhere!
