This where store and select up to 9 items you frequently want to use. Use keys 1-9 to immediately select an item on the hotbar. Crosshair The crosshair is the small cross in the middle of the screen. It shows the exact point where your item is used on. Health, Armor, Oxygen, XP, Hunger Bar
 * The Harts represents your health. If it drops to zero you die and respawn at the location you first entered the world.
 * The green bar is the XP bar. The blocks of this bar show how much XP you still need for your next level. Your current level is displayed in a green number. The XP levels are used in enchanting. You lose all your levels if you die.
 * The meat pieces is your hunger bar. The hunger bar goes down by being active. If your hunger bar is full enough it will automatically restore your health. If your hunger bar runs out you lose health. Eat food to restore your hunger bar and health.
 * The grey shirts represent your armor if you wear it. Armour takes some of the damage you take from enemies.
 * If you are under water, you will have bubbles on your HUD. The longer you stay under water, the more bubbles on your HUD will burst. If you lose all your oxygen you will lose health.
