Health

The health gauge and monitor in Minecraft is based on a single row of 10 heart icons. Each full heart contains two halves, one hit point each (full health is 20 hit points).

Hearts
Hearts make up the health meter for the player and mobs in the Survival, Hardcore, and Adventure modes. Each heart represents two hit points, for 20 hit points. Hit points are lost as a percentage of those hit points. As it appears on the health bar, you lose 1 point at a time.

Hit points can be lost by: starving; taking fall damage; being attacked by a hostile mob (or another player if PvP is on); being shot with an arrow; being on fire; touching lava, fire, or a cactus; drowning underwater; suffocating inside a block; falling into the void; having certain status effects, getting caught in an explosion or. When the health meter shows two hearts or less (20% or less health), it will begin to shake violently, warning that the player's demise is imminent if health is not restored.

Health can be recovered through several means, both "naturally" and through status effects such as potions provide.
 * The "instant health" potion effect will restore health immediately, the amount depending on the source and effect level.
 * On Peaceful difficulty, the health meter will continuously refill over time.
 * On other difficulties, health regenerates slowly when the player's saturation is at or above
 * The player will lose health when the hunger is
 * The "regeneration" effect makes health regenerate fairly quickly. Aside from potions of regeneration, this is also provided by beacons and golden apples. The "basic" golden apple provides it (level II) only for 5 seconds, restoring a total of .  The "enchanted" golden apple provides it for much longer (30 seconds) and at much higher level (level V, over eight times the healing speed of the basic golden apple) and in total restoring about.
 * The "health boost" effect adds 4 per effect level to the players total health, which is removed when the effect expires.  After the effect expires, the player's health may remain above the normal maximum, but the extra health will not be recovered once lost to damage.  This effect can only be gained through "cheat" commands, prepared command blocks, or mods. At the maximum level of 255, the player has 522 hearts.
 * The "absorption" effect likewise adds for each effect level.   This special health cannot be healed or regenerated by normal means. Naturally, it will be removed when the effect expires.  Absorption can be gained by eating either type of golden apple.

Damage is split between the health and armor bars. Each full armor point takes 8% of damage, to a maximum of 80%, rounded up.

On Hardcore mode, hearts have a different texture

In Creative and Spectator mode the player still has health, but it is hidden from the interface, and the player is invulnerable to everything except falling into the Void or.

Death


Death occurs when all of a player or mob's hit points are depleted. For players, a "You died!" (Survival) or "Game over!" (Hardcore and formerly Survival too) screen will appear with the player's score displayed (before Beta 1.9pre2, it had &e0 as the score), and the player has the option to respawn at the spawn point (either the last bed the player slept in, their default spawn point (their first spawn point in the game), or a spawn point created by commands) or return to the title Menu. In Hardcore Mode, the player cannot respawn and the world will be deleted. Any items and/or blocks that were in the player's inventory are dropped from their head and scattered around the spot where the player died (unless the player uses the cheat to keep their inventory with the use of this command: /gamerule keepInventory true). If they come in contact with dangerous blocks - like lava, fire or cactus blocks - they will be destroyed. Otherwise, according to Notch, "they decay after five minutes, except if the chunk is unloaded, in which case they last forever". The player will also lose any experience accumulated reverting the level back to 0 (unless the player uses the command /gamerule keepInventory true). (xp can also be picked up where the player died.)

Mobs fall to their left side to the ground when killed, as shown in the image. The player also falls sideways when killed. In the Pocket Edition, when the player dies, the screen is tilted simulating a broken neck and it infinitely zooms in, but if they die while in their inventory, the character falls over and will stay there until they exit the inventory.
