How to make this script in G HUB?

[Space Distance]

I already have a basic LUA script here that I grabbed from another site;

EnablePrimaryMouseButtonEvents(true);
function OnEvent(event, arg)
if IsKeyLockOn("capslock")then
if IsMouseButtonPressed(1) then
repeat
MoveMouseRelative(0,-1)
Sleep(1)
until not IsMouseButtonPressed(1)
end
end
end

This script is doing the reverse of anti-recoil script and that is what I wanted however is it possible to make a script where if you pressed the Left Mouse button it will simulate an upward mouse movement but at the same time it will delay the shooting of the weapon for a few millescond.

Basically if you're doing this in-game instead of doing body shots it drags the crosshair upward and if you time it right it will do headshots instead.

Not sure if this is possible since I don't know anything about scripting/
