AHK CS:GO Triggerbot

Hello
I'm Currently Trying to make a CS:GO Triggerbot using only AHK
i heard it is possible because of colors since when you aim at someone the crosshair color changes
it seems fairly possible
anyone can help?
btw im a complete noob at coding including AHK
so if someone could come up with a code?

#NoEnv
SendMode Input
SetWorkingDir %A_ScriptDir%

; iloveesl
NRA := 1

; SS
^!p::Suspend

; NR
~LButton::
while GetKeyState("LButton") & NRA
{
DllCall("mouse_event", uint, 1, int, 0, int, 1, uint, 0, int, 0)
Sleep, 15
DllCall("mouse_event", uint, 1, int, 0, int, 2, uint, 0, int, 0)
Sleep, 5
}
return

; Nades
~MButton::
if GetKeyState("LButton")
{
NRA := 0
Sleep, 3000
MouseClick, Left,,,,, U
NRA := 1
}
return

Insert::suspend
