The first number (and the only one that matters for movement) is the player's yaw (between -180° and 180°) which corresponds to horizontal rotation.
The second number is the player's pitch (between -90 and 90) which corresponds to vertical rotation.
- East = Positive X = -90°
- South = Positive Z = 0°
- West = Negative X = 90°
- North = Negative Z = 180°
This section shows which block the player is looking at, as well as it properties.
