Using StreamWriter to log realtime GameObject coordinates

[SOLVED]


Hey folks!

Im trying to log the X, Y, and Z coordinates of two cubes (for starters), and I would like to log these coordinates to a textfile, during Update() and for as long as the application is running. It wont run for very long, but thats beside the point. Ive scripted this so far, which gives me a new textfile in my project library, but nothing is actually written to it:

Code (csharp):

1. import System.IO;
2. import System;
3.  
4. var Lx: float;
5. var Ly: float;
6. var Lz: float;
7. var Rx: float;
8. var Ry: float;
9. var Rz: float;
10. var coordText: String;
11. var path: String;
12. var sW;
13.  
14. function Start () {
15. sW = new StreamWriter("TestFile.txt");
16.  
17.     }
18.  
19. function Update () {
20.  
21. Rx = gameObject.Find("Rhand").transform.position.x;
22. Ry = gameObject.Find("Rhand").transform.position.y;
23. Rz = gameObject.Find("Rhand").transform.position.z;
24. Lx = gameObject.Find("Lhand").transform.position.x;
25. Ly = gameObject.Find("Lhand").transform.position.y;
26. Lz = gameObject.Find("Lhand").transform.position.z;
27.  
28. coordText =  Rx +"," + Ry + "," + Rz +"," + Lx +","+ Ly+ ","+Lz;
29.  
30. if(Input.GetKeyDown("b")){
31. WriteFile();
32. }
33.  
34. }
35.  
36. function WriteFile(){
37. sW.WriteLine(coordText);
38.  
39. }

I suspect it is because im not doing sW.Close(); at any point in time, but im not sure where I should do this? if I do it in update, it will close every frame, which is not desirable I guess? Ive taken a look at other forum posts and examples, but none of them seem to write anything in realtime, its mostly done once in the Start() function, so Im confuzzled =)

EDIT: Solved it by using Input.GetButtonDown instead =)
Also added sW.Flush() to the WriteFile() function, which works like a charm. Every frame, the XYZ of both gameobjects are being logged to my textfile
