HUD

The HUD or Heads Up Display is a graphical interface overlaid onto the screen to give the engineer information. It includes a cross-hair, compass, hotbar, the hotkey tool-tip, health bar, and equipment status.

Compass
The compass shows the cardinal directions relative to the engineer's current facing and also indicates the directions of any vehicles with an icon. It also shows the direction of waypoints from the HUB or beacons.

Hotbar
The hotbar is a list of numbered slots, similar to hotbars found in many other games. Placeable entities such as vehicles and buildings can be placed in the slots, allowing them to be selected and placed. For example, if you wish to build conveyor belts without having to enter the build interface every time, you can place it in the hotbar by entering the build menu and hovering over the image of the conveyor belt with the mouse. Then you select a number (1-9) and the conveyor belt will be placed in the corresponding slot on your hotbar.

The hotbar currently serves for building shortcut only, it does not interact with player's inventory.

Tool-tip
The tool-tip menu lists several tool icons and their associated hotkeys.
 * - Enters the build menu.
 * - Deconstructs and returns items to the engineer's inventory.
 * - Flashlight
 * - Scanner operation or vehicle controls if driving.
 * - Opens communications
 * - Personal Inventory
 * - Open map (experimental)

Health status
The health status bar indicates how close to death the engineer is. If a tool is in play, a corresponding status bar, showing the status of the tool will appear above the engineer's health bar. If fuel is required to operate the tool, the fuel available in inventory will be displayed. If there is no fuel available, there will be a warning icon indicating that the tool will not work.
