showing images randomly from the same category

  Hi @MicolG ,

  I would start by adding a short inline_script at the start of the trial sequence where you determine the file name based on the category_name variable and a randomly selected digit between 1 and 5 (inclusive). This should be in the prepare phase.

  import random
  var.my_image_file = '{}{}'.format(var.category_name, random.randint(1, 5))
  

  And then you can use the variable my_image_file in the script of your sketchpad :

  draw image center=1 file=[my_image_file]
  

  Do you see the logic? And note that the two scripts use a different language: Python for the inline_script and OpenSesame script for the sketchpad script.

  Thank you @sebastiaan , I definetely got your point.

  Could you tell me what syntax should I use for OSWeb (javascript)?

  Hi @MicolG ,

  In JavaScript (i.e. an inline_javascript item) the logic is the same, but the details of the implementation are a bit different. Specifically, there is no randint() function in JavaScript, so you need to implement it yourself.

  function randomInteger(minval, maxval) {
      return minval + Math.floor(Math.random() * (maxval - minval + 1))
  
  }
  vars.my_image_file = vars.category_name + randomInteger(1, 5)
  console.log(vars.my_image_file)
