title: How to store position data and export it into a csv file?
body: <p>I am currently working on a school project where I'll be using motion capture and unity. It's made for the elderly to improve their cognitive and motoric functions. I want unity to be able to record their movements into a csv file to see how well they are doing. I want the x, y and z co-ordinates recorded against time in excel. </p>
  
  <p>I'm using perception neuron for my motion capture which have a total of 32 sensors. The 3D model in unity has 32 different parts/limbs that move, including the fingers. I added a picture of it here:</p>
  
  <p><a href="https://i.stack.imgur.com/QZpZN.png" rel="nofollow noreferrer">This is what the 3D model for perception neuron looks like</a></p>
  
  <p>I tried to use this example but it extracts data as a text file.</p>

      public class fileMaker : MonoBehaviour
      {
          public static void putBytes(ref byte[] output, int index, float value)
          {
              //turns a float into its 4 bytes and then puts them into the output array
              //at the given index
              byte[] data = BitConverter.GetBytes(value);
              output[index] = data[0];
              output[index + 1] = data[1];
              output[index + 2] = data[2];
              output[index + 3] = data[3];
          }
          public static void makeFile(Vector3 position)
          {
              //each float is 4 bytes.
              //3 floats in a vector 3(x,y,z) and 3x4 =12!
              byte[] output = new byte[12];
              //get bytes for each part of our lil vector3
              putBytes(ref output, 0, position.x);
              putBytes(ref output, 4, position.y);
              putBytes(ref output, 8, position.z);
              File.WriteAllBytes(Application.dataPath + "/log.txt", output);
          }
          public static void loadFile()
          {
              //converts it all back into pretty print
              if (File.Exists(Application.dataPath + "/log.txt"))
              {
                  byte[] input = File.ReadAllBytes(Application.dataPath + "/log.txt");
                  int length = input.Length;
                  if (length == 12)
                  {
                      Vector3 ourVector3 = new Vector3();
                      ourVector3.x = (float)BitConverter.ToSingle(input, 0);
                      ourVector3.y = (float)BitConverter.ToSingle(input, 4);
                      ourVector3.z = (float)BitConverter.ToSingle(input, 8);
                      print("Position saved in file (" + Application.dataPath + "/log.txt): " + ourVector3.ToString());
                  }
  
              }
          }
      }

  <p>I want unity to record position data for each part. Does this mean I have to write a script for each limb (which is a game object) or can I write one single script and connect to all the limbs? </p>
  
  <p>I also want to know if I can change this code above to store data as a csv file instead of a text file; can I change a few lines or do I have to make a new script? I'm very new to unity and computer programming.</p>
