Temptive moving perimeter scan

[Noo0B]

Hi,
I'm pretty sure there's better ways to achieve the same goal;
I tried breadcrumbrling with the perimeter color and it worked weomewhat well, but if anyone would like to try and expand on this, and maybe correct where I went wrong I'd appreciate.
It freezes at around 359 degrees, and increasingly skips at 180.
In concept, it is somehow able to follow a moving, variable perimeter by estimating it's center position.
So, here it is:
#SingleInstance, force
#MaxThreadsperHotkey 2
SysGet, Monitor2, Monitor, 2
CoordMode, Pixel
CoordMode, Mouse
SetBatchLines, 10
SetDefaultMouseSpeed, 0
SetKeyDelay, 0, 0
