How to Add Mods to Your Operation Harsh Doorstop Server

Add mods to an Operation Harsh Doorstop server

Mods for Operation Harsh Doorstop come from the Steam Workshop. On the server they live as folders inside the Mods directory – there is no mod list or configuration file in which you enable them. Maps, factions and game modes from mods are selected through the startup parameters of your server instead.

Step 1: Download the mod

  1. Open the mod in the Workshop
    Open the desired mod in the Steam Workshop of Operation Harsh Doorstop and subscribe to it. Steam then stores the mod locally on your PC – inside the Steam directory under steamapps/workshop/content/736590/<workshop ID>.

  2. Alternative: download via SteamCMD
    You can also download the mod on your PC without subscribing, using SteamCMD:

    steamcmd +login anonymous +workshop_download_item 736590 <workshop ID> +quit
    

    The files then end up under steamapps/workshop/content/736590/<workshop ID> as well.

  3. Locate the mod folder
    Inside that directory you find the actual mod folder. That folder – not the folder named after the workshop ID – is the one you copy to the server later. Its name is usually stated in the mod description.

Step 2: Upload the mod to the server

  1. Stop the server
    Stop your server via the dashboard.

  2. Connect via SFTP
    Connect to your server via SFTP.

  3. Open the Mods folder
    Navigate to the following directory. If the Mods folder does not exist yet, create it:

    /HarshDoorstop/Mods
    
  4. Upload the mod folder
    Upload the complete mod folder into this directory. Each mod gets exactly one folder there:

    /HarshDoorstop/Mods/MY_MOD
    
  5. Start the server
    Start your server once the upload has finished.

Step 3: Enable the mod content on the server

Uploading the mod is not enough: maps, factions and game modes additionally have to be selected in the startup parameters of your server. You adjust those in the dashboard.

Parameter Meaning
<MapName> The map the server starts on – for a map mod, the name of the modded map
?BluforFaction= Faction of the blue team
?OpforFaction= Faction of the red team
?game= Path of the game mode class from a mod

An example set of startup parameters for a modded server looks like this:

MODDED_MAP?BluforFaction=MODDED_FACTION?OpforFaction=MODDED_FACTION?game=MODDED_GAMEMODE_PATH

What players need to do

Maps, factions and game modes from mods also have to be present on the PCs of your fellow players. The most reliable way is for everyone to subscribe to the mods used on the Steam Workshop and restart the game afterwards.

Remove a mod

  1. Stop the server
    Stop your server via the dashboard.

  2. Clean up the startup parameters
    Remove every reference to the mod from the startup parameters – modded map, factions and game mode. If a reference remains, the server will not start correctly afterwards.

  3. Delete the folder
    Delete the mod folder from /HarshDoorstop/Mods via SFTP.

  4. Start the server
    Start your server.
