Not sure if others have experienced this, but thought it’s worth a shot in case it’s a fixable bug.
I’m making a task where I want to be able to set a mouse position given a specific angle (around the centre) to help with a response. However, getting some problems when trying to mouse.setPos() to anything - even (0,0)!!
I stripped it back completely and tried with some v basic code, and still getting the same problem. It looks, weirdly, like things are being set relative to the top right corner of my laptop. Setting location to the origin puts it there, and negative x values take it further left (rather than starting centre and moving left of centre). I’ve attached code here for what I’ve been using to look at this problem.
import numpy as np from psychopy import visual from psychopy import event, core, gui, data, logging test_loc = 0 #force macbookpro at the moment... #set screen parameters if test_loc == 0: #laptop for testing, macbook pro (retina atm) resxy = [1680, 1050] #laptop pixel resolution reshz = 60 #refresh rate of the screen sw = 28.5 #screen width vdistcm = 50 #distance from screen mon = 'mbp' #identifying string for the monitor on the computer! retina = True colours = np.array([ [255, 255, 255], #white? [255, 255, 21], #yellow ? [ 0, 0, 255], #blue [150, 150, 150] #dark grey (neutral) ]) #create the screen screen = visual.Window(size = resxy, units = 'deg', colorSpace = 'rgb', color = (-1,-1,-1), #black background fullscr = True, monitor = mon, useRetina = True, #set to false if not on a retina screen winType = 'pyglet') mouse = event.Mouse(win = screen, visible = True, newPos = [0,0]) #set up mouse for the task (`visible = False` will stop it being visible on screen. default is visible) core.wait(1) mouse.setPos(newPos = [2,2]) core.wait(1) mouse.setPos(newPos = [-2,-2]) core.wait(1) mouse.setPos(newPos = [-5,-7]) core.wait(1) screen.close()
Not sure why i’m getting this bug, so any advice would be great. I’m running one of the new macbook pros with OS X Mojave (this is quite probably the problem…) with psychopy v 1.90.3.
