Trying to get an aimbot working

[chibiterasu445]

I've been trying to use this aimbot to follow a white circle, here it is as following

IF NOT A_IsAdmin ; Runs script as Admin.
{
Run *RunAs "%A_ScriptFullPath%"
ExitApp
}

#MaxThreadsPerHotkey, 2
CoordMode, Pixel, Screen
#singleInstance, Force
toggle = 0


F8:: ; press F8 to toggle the loop on/off.
SoundBeep
Toggle := !Toggle
While Toggle
{ ;-- Begin of loop.
PixelSearch, colourx, coloury, 0, 0, 1283, 873, #FFFFFF, 255, Fast RGB

IF ErrorLevel = 1 ; IF NOTFound.
{
sleep, 1000
}

IF ErrorLevel = 0 ; IF Found.
{
Click, %colourx%, %coloury% Left, 0 ; Click on it.
sleep, 1000
}

} ;-- End of Loop.
return
