This article documents the Data field in the Spawn Entity packet. The field is of type Int, and the meaning of its contents depend on the type of entity being spawned, as defined in the Type field of the same packet, and is documented below.

Item Frame

Value Orientation
0 Down
1 Up
2 North
3 South
4 West
5 East

The Notchian client clamps invalid values into the valid range through the modulus operator. If the resulting value is negative, the absolute value is used.

Velocity in the packet is always ignored.

Painting

Value Orientation
2 North
3 South
4 West
5 East

The Notchian client clamps invalid values into the valid range through the modulus operator. If the resulting value is negative, the absolute value is used.

Warning.png Although the values of 0 and 1 are invalid, the Notchian client uses the same clamping algorithm as Item Frame, which can result in any value from 0 to 5. If the resulting value is invalid, the entity will fail to spawn.

Velocity in the packet is always ignored.

Falling Block

Field name Field type Notes
Block state ID Int ID of the block state that the falling block will represent.

Velocity in the packet is always ignored.

Fishing Hook

Field name Field type Notes
Owner Int The entity ID of the owner

Warning.png If the entity with the Owner ID doesn't exist in the client, the entity will fail to spawn.

Velocity in the packet is ignored, and instead should be inferred from the shooter's position.

Huh.png The following information needs to be added to this page:
What's the exact algorithm for determining this?

Projectile

Field name Field type Notes
Owner ID Int The entity ID of the owner

Warden

Field name Field type Notes
Pose Int If a value of 1 is specified, the Warden will spawn in the emerging pose.

Any other value is silently ignored.
