Logitech G-Hub :: Automated_Dropshot_Protocol

Hardware upgrade complete. New peripheral acquired: Logitech PRO X SUPERLIGHT 2.

Most people focus on the weight (60g) or the Hero 2 sensor. I was interested in the API. I discovered that G-Hub supports full LUA scripting. This opens the door for automation that executes faster than human reaction time allows.

System Logic: Protocol Breakdown

• State Check: The script continuously monitors the delta time between RMB (Aim) and LMB (Fire).
• Threshold: If this delta is less than 300ms (variable maxInterval), the system flags the situation as “Panic Fire.”
• Action: Instead of just firing, the system injects Mouse 4. The character drops to the ground while the barrel keeps spitting lead.
• Reset: Once RMB is released, the character automatically stands up via Mouse 5.

The Problem: Panic Fire

In DayZ (and other tactical shooters), the most critical moment is CQC (Close Quarters Combat). You turn a corner, bump into a camper. Adrenaline spikes. You start “panic firing” from the hip. Usually, you stand there like a static target and get sent back to the coast.

A manual “dropshot” (going prone while shooting) requires a complex finger gymnastics sequence: HOLD RMB + CLICK LMB + HOLD C (or your prone bind). Under stress, muscle memory often fails.

The Solution: Scripted Response

I wrote a script that automates this. If I am holding the Right Mouse Button (readiness/ADS) and I click the Left Mouse Button (fire) very quickly, the script automatically injects the keystroke to go prone.

In-Game Configuration

For the code to interpret the intention correctly, you need specific binds in DayZ:

• Mouse Button 4 (Thumb Front): Prone
• Mouse Button 5 (Thumb Back): Stand Up / Crouch

Source Code

Here is the LUA script for the G-Hub profile:

EnablePrimaryMouseButtonEvents(true)

local rightPressed = false
local lastRightPressTime = 0
local maxInterval = 0.3  -- 300 ms limit for "panic" detection

local function getTime()
    return GetRunningTime() / 1000.0
end

function OnEvent(event, arg)
    -- Debug log (uncomment for testing)
    -- OutputLogMessage("Event: %s, Arg: %s, RightPressed: %s\n", tostring(event), tostring(arg), tostring(rightPressed))

    local currentTime = getTime()

    if event == "MOUSE_BUTTON_PRESSED" and arg == 2 then
        lastRightPressTime = currentTime

        rightPressed = false
    elseif event == "MOUSE_BUTTON_PRESSED" and arg == 1 then
        if (currentTime - lastRightPressTime) <= maxInterval then
            rightPressed = true
        end
    elseif event == "MOUSE_BUTTON_RELEASED" and arg == 2 then
        if rightPressed then
            PressMouseButton(5)
            Sleep(50)
            ReleaseMouseButton(5)
        end

        rightPressed = false
    end

    if rightPressed then
        if event == "MOUSE_BUTTON_PRESSED" and arg == 1 then
            -- Sleep(400)
            PressMouseButton(4)
            Sleep(50)
            ReleaseMouseButton(4)
        end
    end
end

Expansion & Modding

This script is merely a foundation. The G-Hub Lua API is surprisingly robust and allows for complex logic beyond simple mouse clicks.

• Tuning: Adjust the maxInterval = 0.3 variable. Lower values require faster reflexes but reduce false positives.
• Humanization: You can add math.random(min, max) to the Sleep() functions to make the delays unpredictable, reducing the risk of heuristic detection.
• Keyboard Integration: If you own a Logitech G-Series keyboard, the API can read keyboard events (G-Keys). You could write a condition where the “Dropshot mode” is only active when a specific toggle key on the keyboard is active.

For those who want to dive deeper into the syntax and available functions, here is the reference manual: Logitech G-Series Lua API (PDF)
Official documentation containing all event listeners, output functions, and hardware identifiers.

Troubleshooting: Access denied?

If the script loads but nothing happens in-game, it is a permission issue. DayZ (and its anti-cheat BattlEye) often ignores synthetic input from lower-privilege applications.

Fix: You must run the Logitech G-Hub agent as Administrator.

1. Close G-Hub completely (check system tray).
2. Right-click G-Hub shortcut -> Run as Administrator.

! Ethical subroutine

This article serves as a technical proof of concept-a demonstration of what is possible when you start treating your hardware as a programmable platform rather than a static tool.

While this gives a distinct combat advantage, it sits in a grey area. It is not an external cheat program, but it automates mechanical skill. Use this knowledge to understand the limits of your hardware, but remember: Automation can replace reaction, but it cannot replace game sense.
