Object Data

In the "Spawn Object/Vehicle" packet, additional metadata about the spawned entity may be provided. The contents of this extra data depend on the type of object being spawned, but it is always an Integer. No matter what, the server must send one integer to the client, although 0 is a valid value. If a number greater than zero is provided (for all entities), the velocity portion of the Spawn Object packet is sent as well.
