The Player is the character users control. They spawn with 10 hearts and die when they reach 0 hearts.
The official name given for the player's appearance is Sam, which is an acronym for “Sam ain’t Minecraft”.
In the default texture pack, the player appears as a green, flat shape with a black square for the eyes (they are only shown at the front of the player, not the back). They never hold any blocks or items in hand. There is currently no way to see yourself as there is no third person mode.
