How to move the cursor sequentially?

The problem can be divided into 2 smaller ones:

1. ReleaseMouseButton(3) is called before the corresponding bullet is fired in the game (thus now I have coded 30 bullets, and it completes execution in the first two or three). I decided to increase the delay through Sleep(50), this gave the expected effect, albeit a weak one, but this is also not an option. there is a much shorter time interval between bullets.

2. Each mouse shift works in such a way that the previous one breaks. For example, let's call:

MoveMouseRelative(0, 0)
Sleep(10)
MoveMouseRelative(0, 15)
Sleep(10)
MoveMouseRelative(0, 5)

For some reason, the third affects the second, and the second affects the first, so I have to adjust all the offsets when adding a new one, and this is a very boring thing and definitely should not work like that.

Functions like EnablePrimaryMouseButtonEvents can be viewed in pdf logitech g-series lua api https://douile.com/logitech-toggle-keys/APIDocs.pdf

Whole code:

function OnEvent(event, arg)
     EnablePrimaryMouseButtonEvents(true);
    if IsMouseButtonPressed(3) then
       repeat
          MoveMouseRelative(0.15)
          Sleep(50)
          MoveMouseRelative(0,40)
          Sleep(50)
          MoveMouseRelative(0,30)
          Sleep(90)
          --MoveMouseRelative(0.9)
          Sleep(100)
          --MoveMouseRelative(0.7) -- 5
          Sleep(10)
         
          if not IsMouseButtonPressed(3) then break end
         
          --[[MoveMouseRelative(0,6)

The function mentioned by Luke in comments might look like the following:

local last_x, last_y

function SetOrigin()
   last_x, last_y = 0, 0
end

function SmoothMouseMoveRelativeToOrigin(x, y, ms)
   last_x, last_y, x, y = x, y, x - last_x, y - last_y
   local tm = GetRunningTime()
   local prev_dx, prev_dy = 0, 0
   repeat
      Sleep(10)
      local t = GetRunningTime() - tm
      local dt = math.min(ms, t) / ms
      local dx = math.floor(dt * x + 0.5)
      local dy = math.floor(dt * y + 0.5)
      prev_dx, prev_dy, dx, dy = dx, dy, dx - prev_dx, dy - prev_dy
      if dx ~= 0 or dy ~= 0 then
         MouseMoveRelative(dx, dy)
      end
   until t >= ms
end

function OnEvent(event, arg)
   SetOrigin()
   ....
      repeat
         SmoothMouseMoveRelativeToOrigin(0, 15, 50)  -- after 50 ms: at (0, 15)
         SmoothMouseMoveRelativeToOrigin(0, 20, 40)  -- after 50+40 ms: at (0, 20), not (0, 35)
   ....
end
