Entities

Entities are non-block creatures that don't align to the block grid.

Base Entity

All entities have the following properties, though usually more. These are just the most important ones. In brackets you can find their respective default values.

Field	Type	Description
Entity ID	Integer	The ID of the entity (0)
X	Double	The X position of the entity
Y	Double	The Y position of the entity
Y-Offset	Float	The height of the entities bounding box (0.0)
Z	Double	The Z position of the entity
Yaw	Float	Absolute rotation on the X Axis, in degrees
Pitch	Float	Absolute rotation on the Y Axis, in degrees
On Ground	Boolean	false for walking/swimming, true for jumping/falling (false)
Width	Float	The width of the entities bounding box (0.6)
Height	Float	The height of the entities bounding box (1.8)
Air	Integer	The amount of air the entity has (300)
Max Air	Integer	The maximum amount of air the entity can have (300)
Fire	Integer	How many ticks the entity will continue to burn (0)

NOTE

Some entries are left out for the sake of brevity, such as the previous position and rotation values or their chunk coordinates.

Position

The (X,Y,Z) coordinate defines where its lowest, center-most point is. For the player, this is on the ground between their feet.

Y-Offset/Stance

The Y-Offset, also called "stance" on wiki.vg, defines the eye-height of the entity. It is relative to the Y-Position.

Entity	Y-Offset
Default	0.0
Player	1.62

Width and Height

The width and height define the size of the bounding box that Minecraft uses for its collision.

Entity	Width	Height
Default	0.6	1.8
