using joystick input for version 1.1

[Matt Lenhart]

Hi Mary,

Since you are collecting a response via script (rather than through an
input mask), you would need to do something like this:

Dim lnEndTime As Long
lnEndTime = Clock.Read + 5000

Do

 If Joystick.Buttons And ebJoystickButton1 Then

  c.SetAttrib "JoystickRTTime", Clock.Read
  c.Setattrib "JoystickRT", Clock.Read - TextDisplay1.OnsetTime

  Joystick.GetCursorPos ptCursor.x, ptCursor.y

  c.SetAttrib "JoystickX", ptCursor.x
  c.SetAttrib "JoystickY", ptCursor.y

 End If

Loop Until Clock.Read > lnEndTime

This will basically loop until 5 seconds have passed, regardless of
when the subject responds (i.e., the object will stay up for 5 seconds
no matter what happens). When the response is detected, however, all
of the necessary information will be logged. This technique is covered
in several samples available on the official PST support site (Run
Trials for Specified Time, Process Responses Template).
