Vehicle Configuration

Get started by viewing the full documentation here!

Each vehicle that is configured to use ULC can have it's own dedicated configuration. This configuration can even be included in the vehicle's resource as a ulc.lua file, this way vehicle developers can deliver their vehicles pre-configured for ULC.

ULC offers a wide range of configuration settings and all features are opt-in.

By default, no vehicles are affected by ULC's functionality. In order to enable ULC for a vehicle, you must configure it. There are two methods for doing so.

How to work on the interface

The UI is built using React, Vite, Typescript, and Tailwind CSS. The React project in /ulc/src builds out to /ulc/html which is where FiveM runs it from.

Follow these steps to run and test locally.

1. cd ulc/src/src
2. npm i
3. Uncomment the debugging buttons in App.tsx.
4. npm run dev
5. View the app in your browser and use the debug buttons to show the UI.

To build the UI to the html folder:

1. Simply npm run build

Contribution guide

1. All changes that effect the ulc.lua config in any way must be 100% backwards compatible. That is, a ulc.lua file that was created on the first day ULC was released must still work today.
   1. Any new features should never throw errors if that config section is not present and by default the new behavior should be entirely disabled.
   2. Changes to the configuration format of an existing feature must also still support the old format.
   3. For this reason, it's imperative that new features be well though-out in terms of the format of their configuration in the ulc.lua files.
