Time-stamped file recording joystick button presses

Question

This is for an experiment we are running in our lab. First the script asks for a participant number and creates a file in C: . During the experiment a participant with a gamepad presses a single button (8), and each time the button is pressed the file is written with the current time. The q button returns a quit message and ends the script.

And it does not work. I think the issue surrounds the joystick. Any help much appreciated.

FormatTime, timestamp, , yyyy_MM_dd_HH_mm
JoystickNumber = 1      
#SingleInstance
#persistent

InputBox, ssnum, Subject Number, Please enter the participant number
if ErrorLevel
    ExitApp
else
thefilename=%ssnum%_T_%timestamp%
    FileAppend,
        (
            %ssnum%%timestamp%
        ), C:\%thefilename%.txt
    return

Loop
{
GetKeyState, state, Joy8
    if state = D
        FileAppend,
        (
            %timestamp%, 
        ), C:\%thefilename%.txt
}

q::
MsgBox Exiting.  Your data is saved in the C drive as %thefilename%.txt
ExitApp

Should this output a file for each time the key is pressed, or have a log file that shows all the timestamps of when the key was pressed? — Elliot DeNolf, May 24 '13 at 18:18
It looks like you are hitting a `return` before hitting your loop. I'll post my suggestions as an answer. — Elliot DeNolf, May 24 '13 at 20:23

The main issue is that you are hitting a return before it even reaches your loop.

I've cleaned up your code a bit as well as turned your loop into a hotkey. This will prevent multiple writes to the file if the key is held. If you need to count holding of the button, you can use the loop you had.

FormatTime, timestamp, , yyyy_MM_dd_HH_mm
JoystickNumber = 1      
#SingleInstance
#Persistent

InputBox, ssnum, Subject Number, Please enter the participant number
if ErrorLevel
    ExitApp

thefilename = C:\%ssnum%_T_%timestamp%.txt
FileAppend, %ssnum%`t%timestamp%`n, %thefilename%

~Joy8::
    FormatTime, timestamp, , HH:mm:ss
    FileAppend, %timestamp%`n, %thefilename%
Return

q::
    MsgBox Exiting.  Your data is saved in the C drive as %thefilename%
    Run % thefilename
    ExitApp
