The Heart Piece is a recovery item which, similar to a Heart Container, is used to increase player health and health capacity. The default starting number of a players hearts is 3, which is equal to 12 hitpoints. Each additional Heart Piece picked up by a player will increase the capacity by a quarter heart (1 hitpoint). Once 4 Heart Pieces are obtained, the player's hitpoints will be filled to the new max capacity.
The Heart Piece can be spawned from Customizable Mob Spawners or dropped from a dispenser. If a player receives a Heart Piece directly into their inventory, from a chest or even another container, the player must drop it on the ground and pick it up for it to be added to their health.

There is currently no limit to the number of Heart Pieces a player can add, which means they can add enough Heart Pieces that eventually a player’s health bar will be longer than the screen.
However, be careful when dropping multiple Heart Pieces, as the game may glitch and not count all of them. Take your time between dropping and picking up these hearts one by one.
