Hi
I am looking for assistance with a visual search task linked with Eyelink 1000. My task involves a target appearing on a screen and when a participant looks at the target I want the routine to end. I have adapted a very similar task where the routine ended when the joystick moving a cursor was over the target. I have included below the code (added to builder) I have adapted to try and achieve this and also included the error message that I get.
Code
Begin routine
''TargetTimer = core.Clock()
inTarget = False
outTarget = True
Each frame
eyeinfo = eyetracker.getLastSample()
stimulus = outer_target
print(eyeinfo)
outer_target.tStop = t # local t and not account for scr refresh
outer_target.tStopRefresh = tThisFlipGlobal # on global time
win.timeOnFlip(outer_target, ‘tStopRefresh’) # time at next scr refres
#each frame-----
if stimulus.contains(eyeinfo) and not inTarget:
TargetTimer.reset()
inTarget = True
outTarget = False
#exits quad
if not stimulus.contains(eyeinfo) and inTarget:
inTarget = False
outTarget = True
if inTarget:
if TargetTimer.getTime() > 0.5:
continueRoutine = False’’
error message

Any help with this will be gratefully received
