Who is Who ? (a little drag&drop game)

[Gianni]

This is a little experiment that makes use of a "Browser Control" embedded in a GUI in order to be able to use AutoIt, HTML, JavaScript and CSS all together.
This little toy will only work on systems with IE11.
The purpose is to drag all the names of the scientists & drop on the right ones. (among scientists it has also infiltrated an intruder). I hope you find it entertaining.
I've posted it here in the hope to have some suggestions on how to improve it all (I mean the interaction between Autoit Javascript html and css). Thanks

little correction on the red flash effect on error when dropping on wrong scientist

[mLipok]

Where is "Doctor Who" ?

 

[wysocki]

error: _ArrayShuffle(): undefined function. Got me to update my AutoIT!

Brilliant piece of work! Newb question about coding technique though: Why put mainline code in a function instead of just inline?

Is in this way to better separate the scope of Local and Global variables
.. for a better explanation have a look here: https://www.autoitscript.com/wiki/Best_coding_practices#Scopes_of_Variables

p.s.

I've made a little variation in the script so to wait a ready state after a page refresh.
