Install DarkRP Modifications on GMod

DarkRP's authors ask you never to edit DarkRP's own files. Instead, everything you want to change lives in a small companion addon called darkrpmodification: your jobs, shipments, entities, settings and any scripts you add. This guide installs that addon from its official GitHub page and shows where each kind of change goes. Checked against the addon's repository (last commit 9 May 2026) and DarkRP 2.7.0, October 2026.

Do you need the full addon?

Not always. The DarkRP tab saves the economy, default laws and F4 menu headings into darkrpmodification, and it creates the two files it needs if they are missing. See Set up DarkRP on your GMod server for that. Install the full addon when you want your own jobs, shipments, entities or modules, or any setting the tab does not cover.

What is inside

Everything sits under lua/ in the addon:

Install the addon

1. Download the repository as a ZIP from github.com/FPtje/darkrpmodification. The file is named darkrpmodification-master.zip.
2. In your server's File Manager, open garrysmod/addons and press Upload files to add the ZIP.
3. Press Extract here on the ZIP. A folder called darkrpmodification-master appears.
4. Use Rename to change that folder to darkrpmodification. The DarkRP tab looks for that exact name.
5. Restart the server so DarkRP loads the addon's files.

You should now see garrysmod/addons/darkrpmodification/lua/darkrp_config/settings.lua.

Make a change

Open the file in the File Manager, edit it and press Save. settings.lua, disabled_defaults.lua, jobs.lua and categories.lua explain themselves in comments at the top. To add a job, put it in lua/darkrp_customthings/jobs.lua, under the comment that says where custom jobs go:

TEAM_BUILDER = DarkRP.createJob("Builder", {
    color = Color(80, 120, 200, 255),
    model = "models/player/Group03/Female_01.mdl",
    description = [[You build things for the city.]],
    weapons = {"weapon_fists"},
    command = "builder",
    max = 4,
    salary = 60,
    admin = 0,
    vote = false,
    hasLicense = false,
})

To change one of DarkRP's own jobs, first switch the default off in disabled_defaults.lua, then paste your edited copy into jobs.lua. Restart the server after any edit, because DarkRP reads these files as it starts and Lua refresh is off by default.

Modules

A module is a folder inside lua/darkrp_modules/ holding Lua files. Files starting with sv_ run on the server, cl_ on players' computers and sh_ on both. Use a lowercase folder name with no spaces. Addons that are meant to sit in garrysmod/addons do not belong in this folder, and DarkRP prints an error in the Console if it finds one there.

Common problems

1. A change did nothing. Restart the server and check you edited the file inside darkrpmodification, not a copy.
2. A Lua error in the Console. DarkRP explains config and module mistakes in plain language when the server starts. Read the message, fix the line it names and restart.
3. Your tab settings vanished. See the warning above about the rename clash.
