Measuring response time
Posted: Wed Oct 02, 2013 8:10 pm
Hello,
I"m trying to build an app that will measure a user's response time by measuring how long after a button is clicked for it to become visible. The simplest solution is to have one button put the milliseconds * -1 into a field then hide the response button and show it after a random interval. Once the response button is clicked it adds the miliseconds to the field and the time difference between the button appearing and the mousedown are recorded in the field.
The challenge arises when I try to record subsequent scores on each line of the field All my attempts to count down the lines with a variable and put the new score on the next line result in errors. I've tried local and global variables, intermediate steps, and a ton of different approaches.
Here's my current card script:
and the response button script:
The stack consists of just the button and the field, and a couple of other buttons to start the game and clear the field. I'll see if I can attach it.
Anyways thanks for the help. I'm sure there's some stupd mistake i'm making but I can't figure out what it is. The recording line works in the message box but not from the button for some reason.

Code: Select all

global showtime

on startgame
hide button 1
put 0 into whichline

end startgame
on nextturn
put random(1000)+500 into waittime
add 1 to whichline
hide button 1
wait waittime milliseconds
show button 1
put the milliseconds into showtime
end nextturnCode: Select all
on mouseDown
put the milliseconds - showtime into line whichline of field 1
nextturn
