Player

The Player is the character that users control in Minecraft, and is generally considered the unofficial main protagonist of the game. The two default player skins are known as Steve, a name suggested by Notch as a joke and confirmed on the 'Profile' page near the section that allows you to change your skins, and Alex, a new skin implemented in 1.8, with all unchanged skins being split between the two default skins. In the Credits, after beating Minecraft you are called a player.

Appearance
There are two default player skins, typically known as Steve? and Alex?, (the question marks are canonically correct, but not strictly necessary.) assigned to each player based on their account ID.

Steve has dark brown hair, brown skin, and blue eyes, with a light blue shirt (un-tucked on the left hand side and in the back), a pair of blue jeans, and gray shoes. Steve seems to have a slight stubble of a light brown beard.

Alex has long bright orange hair hanging to the left side, pale white skin, and green eyes, with a light-green shirt (un-tucked on the right side, and a dark green belt wrapped around it), a pair of brown pants, and grayish boots. Alex appears to have pinkish lips, and has thinner arms than Steve.

Both player skins are intended to be generic, genderless representations of a human being, although the player's skin can be changed.

In the Console edition, the player's default skin can vary from Steve to seven other player skins. These skins have names and are listed below. Multiple skin packs are also available for purchase on the Xbox Live Marketplace and the PlayStation Network.

Personality and abilities
As expected from a generic player character, the player character's personality is entirely up to the player controlling them. They can have a kind personality and can work with other players to survive, or act ruthless and kill other players for their items, at the cost of likely being known as dangerous and possibly being hunted down. The player seems to be very strong, as they are able to destroy many blocks with their bare hands, and carry enormous loads of blocks, although the right tools break them faster. The player is also able to "talk", by pressing the Chat key ( by default) and typing the words in.

Pocket Edition
In the Pocket Edition, the player makes an "oof" sound when taking damage like in beta PC. In iOS versions of the Pocket Edition, Steve was named Stevie by default before 0.7.0, whereas in Android versions of the game, they have always been named Steve, as normal. A rare glitch in this edition allows a player clone to appear in multiplayer which mimics the player.

Console Edition
In the Console Edition, there are 8 defaulted versions of Steve for the player to use (as well as many packs of new skins featuring non-Steve characters from various video games, such as  ' Splosion Man from his titular indie game and Master Chief from the Halo series). There are also skins featuring different mobs, such as skeletons, zombies, and the Ender Dragon. The 8 default skins are Steve, Boxer Steve, Cyclist Steve, Tennis Steve, Scottish Steve, Prisoner Steve, Tuxedo Steve, and Athlete Steve. Some variants of Steve look nothing like him, while all are him wearing different clothes with different hair, skin and eye colors.

Health Meter
The player has 10 full hearts or 20 health points. One full heart represents two health. When the player's hunger bar is at 18 points or higher, their health will slowly regenerate by half a heart every four seconds. The hunger bar depletes faster when the player does things like sprinting, jumping, attacking mobs, and mining, and it can be refilled by eating food. If the hunger bar is at 17 points or lower, the player will not regenerate health unless in Peaceful difficulty (or under the effect of certain potions). If the hunger bar is down to 0, the player will start starving and losing health. On Hard difficulty, starvation will kill you. On normal difficulty, it will bring you down to half of a heart. On easy difficulty, it will bring you down to 5 hearts. On peaceful difficulty the health bar will recover regardless of hunger but will still take starvation damage, and the hunger bar will not lose any points, even when under the effect of food poisoning. Notably, if the player is killed by fall damage, mobs, or other things, Right after the death, the screen will say, "you died! Would you like to respawn or exit?" (Note that if you respawn, all of your progress will be lost). If you exit, and re-enter, the same screen will show up.

Movement
The player walks at a rate of about 4.317 meters (blocks) per second. This means that they can walk a total of 5181 blocks (5.2 km) in one Minecraft day.

The player is able to sprint, draining the food bar considerably (10×) faster than usual while doing so. The player is capable of sprinting approximately 5.612 blocks per second, as opposed to the regular pace of 4.317. The player can jump four blocks horizontally when sprinting. The player cannot sprint if there are only 6 points or fewer left in the hunger meter. Sprinting is activated by double-tapping the forward key (default ) then holding it, or by pressing the sprint key ( by default).

Sneaking is a feature activated by holding the sneak key (default is ). Sneaking prevents players from falling one or more blocks, making it highly useful for building horizontally outwards over empty space. If you are past the edge of a block and you stop sneaking, you will not fall off of that block. Additionally, the player can still dismount blocks while sneaking by jumping over the block's edge.

In Creative mode, the player flies at about 10.89 blocks per second.

The maximum height a player can jump without the "jump boost" effect is about 1.252 blocks.

Gameplay HUD
The onscreen heads-up display (HUD) consists of the player's health bar, hunger bar, experience bar, and hotbar. The armor rating bar appears above the health bar if the player is wearing armor and the oxygen bar appears if the player is submerged in water. The HUD also contains the crosshair, and held object (or fist). The HUD can also be toggled by.

Experience
Experience points (XP) can be gained via experience orbs when killing mobs or mining certain minerals. The current level is indicated by a green number above the HUD, and the experience points can be used to enchant weapons, tools or armor with different useful attributes and skills (see enchanting table.) Anvils require experience to use.

The level increases by obtaining enough experience points. All levels and experience are lost upon death, but can be partially restored by picking up the experience orbs at the place of death.

Experience is also obtained through activities such as mining, smelting (experience is only given when already-smelted items are taken out of the furnace), fishing, and animal breeding.

Modes

 * In Survival mode, the player is able to place and destroy blocks, and use all tools available. The player has limited health (heart icons), hunger (drumstick icons), and oxygen (bubble icons) and it takes time to break blocks.
 * In Creative mode, the player has the ability to fly by double tapping the jump key(default ) and to place infinite number of blocks, but with limited use of crafting and tools. The player cannot take damage (except from falling into the Void, or, with cheats enabled, typing the command ), has no hunger and has unlimited oxygen, and breaking blocks is instantaneous.
 * In Hardcore mode, the player cannot respawn and the difficulty level is locked on hard mode. (If playing on a hardcore multiplayer server, the player is automatically banned from that server when they die.)
 * In Adventure mode, there are no changes from Survival mode aside from being unable to break or place blocks unless they possess a tool with the CanDestroy NBT data tag for that block, or have a block with the CanPlaceOn tag. This game mode can only be played by having cheats enabled and typing the command, , or , or by just opening a multiplayer (including LAN) world.
 * In Spectator mode, you can see inside an entity, fly through blocks, and open inventories, but you cannot break blocks or change inventories. Along with Adventure Mode, it can only be accessed by typing in, , or . However, with the Debug Mode world type, the gamemode is locked as Spectator Mode.

Customization
Users can change their character's skins; this can be done on the Preferences page of Minecraft.net by uploading a PNG image file, which will then replace the default skin.

The Console Edition has a separate default skin for each player. The ability to change that skin is available using the Change Skin option in the game. People who already have the removed skin packs can still use them and even re-download them (so they're still being hosted). If the removed skin packs are redownloaded on someone else's console they will become available to any profile on that console (provided the skin pack doesn't have a demo version to default back to).

In the Pocket Edition, the player uses the default skin, and it can be changed by changing the char.png in the game's files or using external apps on both iOS and Android. One exception for iOS will need you to have iOS 5 or below, or a jailbroken device.

Trivia

 * The player's eye level (According to coordinates while pressing ) is 1.62 meters. Since their eyes are 28 pixels above their feet, leaving 4 pixels above their eyes (.23m), Steve is approximately 1.85 meters tall (6'1"). This seems to be confirmed by the game's code that shows Steve's hitbox being 1.8m tall and 0.6m wide.
 * The Player's total cubic volume is 1664 cubic pixels, and since each player pixel is 193.67 cubic centimeters, the player's total volume is 322,273 cubic centimeters. The average human body weighs 1.062 grams/cubic centimeter. This means that the player's weight is approximately 342Kg (754 lbs). With these figures, the player would have a BMI of approximately 105.5, where a person with a BMI of ≥30 would be considered obese.  However, if you move your player inside another one, you can see that players are, in fact, hollow inside, so most likely do not weigh nearly as much as the math suggests.
 * The old player damage sound can be found in the game files as classic_hurt.ogg.
 * Zombies wear the same clothing as Steve. This has led to the discussion whether zombies are actually the dead bodies of past Steves.
 * The player is right handed as they hold weapons, like swords, in their right hand. But they are left eye dominant, meaning they shoot left handed by holding the stock of a bow in their right hand. An easy way of seeing this is by charging a bow and pressing the Toggle Perspective key ( by default).
 * The player seems to have peripheral vision. Lights and lit objects are more visible near the edges of the display (only with graphics set to "fast").
 * Steve's terminal velocity is 162 km/h (100 mph), less than the average human's, about 190 km/h (120 mph).
 * The Player appears to be very strong, being able to carry an entire inventory of gold blocks, which would weigh nearly 45,000 metric tons. However, it's possible the player's inventory goes to some kind of hammerspace; after all, they don't look like they're carrying around a small mountain. Nor does the player have any visible backpack.
 * Since the player retains the same volume when carrying a full inventory of gold blocks, they can achieve a density of 109458g/cc, denser than the densest element, and have a gravitational pull 143.67 times Earth's gravity.
 * The player appears to be able to carry a whole inventory of enchanted golden apples, nearly 320,001 metric tons weight.
 * The Player appears to be very experienced in jumping, as they can jump over 1 meter high (one block).
 * Sometimes when you eat something, you can hear the player burp and one extra food item will disappear.
 * The sides of your field of view are stretched out (for example wait until sunset and look at the sun out of the corner of the screen. It will be twice as wide as tall). This may be referring to real life because we focus on certain objects in our field of vision, and everything else is blurry until we focus on it. It also may be due to the change from the original 4:3 aspect ratio to 16:9. Simply stretching the sides accomplishes this without actually changing anything.
 * The player is light enough to not crush a pig while riding it. The pigs are also pretty strong as they can carry a human with gold armor on with a full inventory of gold blocks, or even enchanted gold apples. Same with horses. This further contradicts the statement above that the player weighs 431.44 Kg (916.16 lbs).
