Hi all,

I am trying to write a script to measure reaction time.

It should show the 10 digits as buttons, then show a random digit and the user has to tap the same digit as fast as possible.

Here are my initial thoughts:

• "buttons": copy from one of the calculators
• random number: take out of the example script
• Show digit: got it
• time to reaction...

Here is where I got stuck...
I was thinking of simple variables (starttime = time() ) and endtime = time()) to measure the elapsed time, but I don't know where to put it...

I tired to put starttime in the setup for my scene and endtime in the touch_began, but it seems that they cannot share variables...

any tips?

Thanks,

Roland
