How to set up trials?

[bobbin_93]

Hi,

I'm wondering if anyone can help me. I've designed an experiment but unfortunately since I'm not really familiar with vizard or coding I've coded for it very long-hand.

I've been told that before I can get the experiment up and running I need to re-organise my code to get it running in a loop of trials, however, I have absolutely no idea how to do this!!!!


I've copied the code below. If anyone could give me any pointers that would be fantastic

p.s. I've not copied the full code as it goes on forever but essentially there are 10 repeats of the same thing in the test phase!


import viz
import viztask
import vizact
import vizinfo
import vizmat
import vizshape

viz.setMultiSample
viz.fov(60)
viz.go()
viz.window.setSize(-1); #set to full screen


#Add score labels for trial 1
success = viz.addText('You ate the insect!', viz.SCREEN)
success_points = viz.addText('+5 points', viz.SCREEN)
fail = viz.addText('You got stung!', viz.SCREEN)
fail_points = viz.addText('-5 points', viz.SCREEN)
info_one = vizinfo.add('Press the space bar to try again')
info_one.translate(0.70,0.3)

#Make score labels invisible
success.visible(viz.OFF)
success_points.visible(viz.OFF)
fail.visible(viz.OFF)
fail_points.visible(viz.OFF)
info_one.visible(viz.OFF)

#Add score labels for trial 2
successTwo = viz.addText('You ate the insect!', viz.SCREEN)
success_pointsTwo = viz.addText('+5 points', viz.SCREEN)
failTwo = viz.addText('You got stung!', viz.SCREEN)
fail_pointsTwo = viz.addText('-5 points', viz.SCREEN)
info_two = vizinfo.add('Press the space bar to try again')
info_two.translate(0.70,0.3)

#Make score labels invisible
successTwo.visible(viz.OFF)
