+# HUD+ +The **HUD** (Heads Up Display) is a vital mechanic in video games, providing important information directly on the screen.+ +The HUD monitors the player's **Oxygen**, **Hunger**, **Thirst**, and **Health**. It also monitors the player's **Temperature** in *Subnautica: Below Zero*. The full set of indicators is only present in Survival and Hardcore modes. In Freedom mode, only Health and Oxygen are displayed. In Creative mode, none of these are present.+ +When the **PDA** is opened, the HUD will display numerical values in place of the icons, allowing players to track the exact amount of hunger they will gain from food, and how long they have until they must eat or drink.+ +At the top of the HUD, the **Depth Meter** is displayed. If a **Compass** is equipped, it will be displayed directly below the Depth Meter.+ +Pressing **F6** allows the player to remove elements of the HUD; pressing it several times will remove more elements.+ +## The Toolbar+ +The Toolbar is located in the bottom section of the HUD. Players may select which items are to be accessed via the Toolbar. There are five slots available.+ +There is a selection of items that can be put in the Toolbar. These primarily include **Small Fauna**, **Tools**, some **Equipment**, and **Placeable Items**.+ +### How to Use+ +1. Open the **PDA**.+2. Hover the mouse cursor over the item that is to be assigned to the Toolbar.+3. Press the corresponding number key (**1** to **5**) to assign the item to a slot.+4. Alternatively, drag and drop an item into a slot, which replaces the previous item assigned to the slot (if there was one).+5. Close the PDA and press the correct key to equip the item assigned to that slot.+ +## Controls+ +| Action | Mouse & Keyboard | Xbox One | PlayStation 4 | Nintendo Switch |+| :--- | :--- | :--- | :--- | :--- |+| Open PDA | `TAB` |  |  | - |+| Assign Item | `1` to `5`, Drag and Drop |  |  |  |+ +## Gallery+ ++The HUD+ ++The HUD as oxygen is depleting+ ++Stats info displaying when the PDA is open+ ++An empty toolbar+ ++A filled toolbar+ ++Dragging an item into the toolbar+ +Pressing a key to put an item in the toolbar+ ++The first version of the HUD, as seen in prototype 1.+ ++The second iteration of the HUD, as seen in prototype 2, this time having larger text.+ ++The third iteration of the HUD, as seen in prototype 3, this time featuring sub depth and smaller text again.+ ++The fourth iteration of the HUD, which now uses a bar for managing the inventory, with a slot dedicated to tools, as well as a different Oxygen timer system.+ ++The fifth iteration of the HUD, which now uses BARs instead of time for oxygen, as well as objectives, food, and a slot for the dive suit.+ ++The sixth iteration of the HUD, which replaces Food with Blood Sugar and adds a Minimap.+ ++The seventh iteration of the HUD, featuring a different overall style.+ ++The eighth iteration of the HUD, with a fixed oxygen bar and removed inventory bar above the hotkey slots.+ ++The ninth and final iteration of the HUD before the current one, with bars for each element, note the unused Thermostat.+ ++HUD Concept Art+ ++Concept Art of different HUD variations+ ++Ditto+ ++Finalized HUD Concept Art, featuring an unused Sun Setting widget+ ++Depth Meter Concept Art+ +## Trivia+ +There were a few unused GUI Elements that were removed during development. This included both an unused Thermometer which was an attachment that you could build to add to your UI, and a Sun Setting/Rising message, which whilst not being added to the UI, did originally function in the form of an on-screen debug message.
