# HUD Basics

The two core components of the HUD framework are:

* The **HUD Manager**
* The **HUD Component**

### HUD Manager

The **HUD Manager** component goes on the root transform of the vehicle and manages the entire vehicle HUD. It can activate/deactivate all the HUD components on the vehicle, and passes common information to all the HUD components (such as a reference to the HUD camera when a camera follows the vehicle).

### HUD Component

The **HUD Component** component represents one specific component of the vehicle's HUD, and enables the **HUD Manager** to activate or deactivate it when the HUD is toggled.

It can be used as a base class to create your own HUD components, or used directly on a game object to mark it as part of the HUD.
