Variable Descriptions

Opperand_Count = 8

Opcode = 1B24F808

• ObjectID:

ObjectID that you are listing attributes for.

• Position X / Z / Y:

New Position of Object. The value is transformed the following way.

(Coordinate * 4) = Position
(Position / 4) = Coordinate
This is done to utilize variable size to prevent moving anywhere outside of the map.
Range of map = 16,000
Range of SHORT = 64,000
64/16 = 4

• UpdateCounter:

Number of movement updates the object has done.

Used to distinguish new updates from potential repeats.

Incremented by 1 each packet.

• 'Direction:

This is the direction for the object to face after moving.

It is calculated by (Angle / 0.0625) where angle is in radians.

• • Additional Notes:

This packet needs to be sent frequently to prevent start/stop in a movement stream.

Also, shorter distances at slower frequency will create slower speed.

It appears the unknown byte is some sort of server-side interpolation variable.

It doesnt have any affect on the client, as far as we can tell.

This byte seems to be related to the 2 variances of ObjController Transform Packets

used (23 vs 21). See them for further detail. The 23 seems to be sent

in a Data channel signifying it being important. This byte is related to a

count of 21's the occur between a group of 23. The 23 is assumed to be start/end

of a chain of movement while the 21 is an update.

TODO: Look into this byte more...
