Cannot Use Dotstim (Even in Builder Mode)

Hi, everyone. When I use the function Dotstim, my compiler just told me that :slight_smile:

2.9650 WARNING Monitor specification not found. Creating a temporary one…

Process finished with exit code 0

and Here is my test code which generated the warning:
from psychopy import visual, core, event
import numpy as np
#win.getMovieFrame(buffer=‘back’)
#create a window to draw in
myWin = visual.Window((600,600), allowGUI=False)

direction = [1, 2] # One left, Two Right
nTrialsPerCond = 10
nTrials = nTrialsPerCond * len(direction)

#INITIALISE SOME STIMULI
dotsLeft = visual.DotStim(win=myWin, fieldSize=300, fieldShape=‘circle’, coherence=0.5, dotSize=20, dir=0, speed=2)
dotsRight = visual.DotStim(win=myWin, fieldSize=300, fieldShape=‘circle’, coherence=0.5, dotSize=20, dir=180, speed=2)

trialClock = core.Clock()

t = 0
while t < 1.5:
t = trialClock.getTime()
dotsLeft.draw() #redraw it
myWin.flip()
#update the screen
#handle key presses each frame
for keys in event.getKeys():
if keys in [‘escape’,‘q’]:
core.quit()
#win.saveMovieFrames(fileName=‘some file.mp4’)

And I cannot use the dot component in the builder mode. I have no idea of what I should do to figure it out. I supposed that there might be some problems with my MacOS Big Sur (I use MBP 18), but when I borrowed my friend’s HP (Windows), I still could not use the dot component. Other functions and components seem to work well.

Hi Draco and Community,

I have the same problem, I tried to run an RDK in the builder in a Mac and in a PC and in both no stimulus appeared, and I had the same error, that is:

Experiment ended.

I’m new in Psychopy and I also have no idea of what to do, if someone has any suggestion it would be great! Thank you all

Hello,

I have the same problem, too, not just in Dots but also in Noise Stim.

I’m using PsychoPy 2021.1.4.

Thanks.

I think this explains the underlying problem, and a temporary solution
