The heads-up display (HUD) appears on screen while the player is in the game. It is superimposed on their view of the game world.
The HUD consists of the user's health, hunger and experience bars, the hotbar, as well as a crosshair that designates the currently focused on block or entity. The armor condition bar appears above the health bar if the player is wearing armor, and the oxygen bar will display above the hunger bar if the player is underwater.
In Creative mode, the health, hunger, oxygen, experience and armor bars are hidden.
Chat is also part of the HUD, in the bottom left corner, showing anything recently spoken or commands recently executed. This can be expanded with T.
The hotbar is a selection bar which appears on the bottom of the screen. It is where the player stores and selects commonly used items. It consists of the bottom nine slots within the player's inventory. The selected item will also display on the right side of the screen , or an empty fist if the slot is empty. When the player switches an item in hand by mouse wheel or 1-9, its name is shown above the experience level for a short period of time. This name will be italic for renamed items.
Players can dual wield allowing a second item to be shown on the left (or right if the player's main hand is set to "left"), along with an additional hotbar slot on the same side. Both the slot and the item are only shown if it contains an item, which can either be added using the GUI or by pressing "swap items". On the Legacy Console Edition and Java Edition, it will show the Off-hand slot with the items equipped on the left of the Hotbar. On the Bedrock Edition, this is not the case although the item is still equipped in the off-hand slot.
In the Bedrock Edition, the hotbar has an additional button for the inventory. However, this is only present on Mobile devices such as the iOS, Android, and the Window 10 (with touch screen). On the New Nintendo 3DS Edition, the hotbar is located on the touch screen and is slightly different.
The crosshair is a small cross in the middle of the screen. It shows the exact point where you will use the tool or item in your hand. The crosshair inverts the colors of the area it is upon, which can result in a nearly invisible crosshair if the area is a medium gray.
If the option for the attack indicator is set to "Crosshair" mode, weapon cooldown time will be indicated by a sword icon near the crosshair which fills, representing the cooldown progress. This sword icon disappears once the weapon is fully cooled. In this mode, if a fully cooled weapon is being held, and a mob or player is in range, the sword icon and an additional plus-sign (+) indicator will be shown below the crosshair, indicating that the weapon is in range to land a full-damage blow.
All status effects the player currently has are shown on the top-right of the screen. Status effects that will run out sooner show farther to the left, and status effects that are about to run out start to flash. Additionally, positive status effects are shown on the top, and negative effects are shown on the bottom. Beacon effects will have a blue (instead of gray) outline, and status effects with particles hidden will not be indicated in the HUD.
Upon mounting a horse, llama, or pig, the hunger bar is replaced by the mob's health, which uses a slightly different heart texture than the player's health bar. Also, upon mounting a horse or llama, the experience bar is replaced by the horse/llama jump bar.
In the Options menu, GUI scale changes the size of the HUD and GUI between "large", "normal" and "small". There is also the default, "auto", which will change the size of the HUD and GUI depending on the size of the game window.
Players can toggle the HUD, the vignette effect on fancy graphics, the pumpkin "view" and the dark lining around the block you are aiming at by pressing the F1 key.[Windows 10 and Java editions only] 
The HUD also contains the debug screen, which can be shown or hidden using F3. Pressing ⇧ Shift+F3 will add the additional pie chart showing resource allocation. Pressing Alt+F3 will show the FPS chart.
The player can choose whether to use their right or left hand. This setting also moves the off hand slot to the opposite side.
