Applescript “Can’t make {x:651.0, y:675.0} into type real.” number -1700 from {x:651.0, y:675.0} to real

Question

I get the error: "Can’t make {x:651.0, y:675.0} into type real." number -1700 from {x:651.0, y:675.0} to real"" when I run this script. I don't know why this happens! Comes from an autoclicker I made, Very simple, but it works with slightly obscure methods (Credit: Clicker, Mouse Position) . Code:

use framework "Foundation"
use scripting additions

set theList to current application's NSEvent's mouseLocation()

(*
set xCoord to theList's x
set yCoord to theList's y
*)
round (theList)
tell application "System Events"
    click at {theList}
end tell

Answer 1

The error you're getting is because you can't round() a structure as a whole, so you need to round its individual components. Replace this:

round (theList)

set theList's x to round (theList's x)
set theList's y to round (theList's y)

Then you'll need to fix a subsequent error caused by theList having x and y keys. Replace this:

  click at {theList}

    click at {theList's x, theList's y}

Answer 2

The error is because you're trying to round the entire record which is {x:651.0, y:675.0}. Instead, round each variable something like this:

use framework "Foundation"
use scripting additions

set theList to current application's NSEvent's mouseLocation()

set xCoord to round theList's x
set yCoord to round theList's y

--round (theList)
tell application "System Events"
    click at {xCoord, yCoord}
end tell
