Server Packet - UpdateTransformMessage (1B24F808)

SWGANH Wiki is a repository of Star Wars Galaxies Developer information. This site is only meant to be used by SWGANH Developer team.

LONG ObjectID

INT UpdateCounter
BYTE Speed
BYTE Direction

Variable Descriptions

Opperand_Count = 8

Opcode = 1B24F808

  • ObjectID:
ObjectID that you are listing attributes for.
  • Position X / Y / Z:
New Position of Object. The value is transformed the following way.
n = X / 4;
if n > 8192 n = n - 16384; 
effective map range is -8192..8192

to convert the a float to position
n = uint16(x * 4.0f + 0.5f);
  • UpdateCounter:
Number of movement updates the object has done.
Used to distinguish new updates from potential repeats.
Incremented by 1 each packet.
  • Speed:


Haven't seen it out side the range of 0..5 yet

  • 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.

:OLD--DATA--Found this to be the posture byte

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.
