Hello all,

I am creating a task where subjects use a likert scale to rate an image but I'm having trouble using bitmap-under-mouse in my experiment because I have overlapping stimuli.
I want the mouse click to read only for bitmap from the range 5 to 12, and therefore I also want to exclude bitmap number 4 (the line under the circles from my likert scale) when getting the bitmap number of the bitmap that was clicked.
I keep getting an error on one line of code in which I use set "set $btmpnumber bitmap-under-mouse range 5 12" saying that range is an unknown variable.
Do anyone spot the mistake in this?

Here is my code.
Thanks!

Emma

You can do it with this demo, try it. All you need to add are 3 images called animal1.jpg animal2.jpg and animal3.jpg. It is a demo I will add to a lesson soon. Make sure you log in to at least version 3.3.0 (current beta, see Twitter for links to it):

options
mouse on
background color 100 100 100

bitmaps # make sure to upload these pictures in your experiment, any image will do.
animal1
animal2
animal3

table animals
animal1 "cat"
animal2 "cat"
animal3 "hedgehog"

task rate_animal
show bitmap @1 0 -170
## next show the yellow slider rectangle
show rectangle 0 0 450 50 255 255 0
## the blue circle in it (20px diameter) can be moved later, this is stimulus number 3
show circle 0 0 20 0 0 255
## now show a green "button" rectangle
show rectangle 350 200 150 50 0 255 0
## now put the text "Continue" in that green retangle, this is stimulus number 4
show text "Continue" 340 200 100 100 255
## now add some instruction text on the screen
show text "not cute" -300 0
show text "very cute" 300 0
show text "Slide the slide left/right" 0 50
##
## now start the dragging options
##
## the "from" option indicates which stimulus can be dragged, it is the circle
drag option from 3
drag option xlim -200 200 ## the stimulus can be dragged between these x positions
drag option ylim 0 0 ## the stimulus cannot be dragged except at y postion y (so it is a slider)
drag option exit 4 ## the stimulus that needs to be pressed to continue, the green rectangle
dragging 5000 ## now the particant has X seconds time
##
## now we do some post processing
##
## first, create a new variable for the actual value YOU need
set $my_value expression DRAG_X + 200
## $drag_x contains the x-coordinate on screen, which is different from $my_value
set $drag_x DRAG_X
## if the circle was not dragged, it won't have a value, so we need to set it manually
## DRAG_CHANGED is system variable. 0 means there was no dragging. 1 means there was.
if DRAG_CHANGED == 0
   set $my_value 200 ## in this case, we put it to the middle value on your 0-400 scale
   set $drag_x 0 ## the actual x-coordinate is screen center, thus x-position 0
fi
## now show the value just above the slider
show text $my_value $drag_x -50
## create a text variable (indicated by %) with text and some variables
set %a paste "Score of the " @2 " on 0 to 400 scale is " $my_value " in " RT " ms"
## now show the next text variable called %a
show text %a 0 100
save RT DRAG_X DRAG_Y $my_value
readmouse l 2 60000 ## the 2 is the stimulus number of the green rectangle
## just wait again until people click continue another time
## this is not necessary
