It's in response to this thread...
What I find interesting is how there are so many solutions to this problem. Here's one from @gasspence A Flashlight (mouse follower) — back in May of 2015. It's one of the oldest templates in the "Template Gallery" category. After posting the "Spotlight" template, I looked at the forum list. I was surprised to see that one second to last. Did I waste my time? Nope, it's different, but it's another coding solution.
...and that's where the "Spotlight" template gets tricky. It uses two "On Drag" actions, so the image can be moved left/right or up/down.
It's not pixel perfect. The "Control Element Position" action is pixel perfect. But if you move the image too far, this can happen...
That's why the "Spotlight" template uses "On Drag". While the speed is set to be a bit fast, this method has some advantages. It works well when using a trackpad or touch device. Your finger doesn't have to move so far to control the spotlight. Plus, if the spotlight exactly matched the touch location, your finger could cover the animation.
