Live For Speed Communication UDP Information
----------------------------------------------
Motion Simulator Support : (OutSim)
--------------------------
The user's car in multiplayer or the viewed car in single player or
single player replay can output information to a motion system while
viewed from an internal view.
This is controlled by four lines in the cfg.txt file :
OutSim Mode 0 :0-off 1-driving 2-driving+replay
OutSim Delay 1 :minimum delay between packets (100ths of a sec)
OutSim IP 0.0.0.0 :IP address to send the UDP packet
OutSim Port 0 :IP port
OutSim ID 0 :if not zero, adds an identifier to the packet
Each update sends the following UDP packet :
unsigned int :time in milliseconds (to check order)
Angular Velocity :3 floats
Orientation :3 floats Heading, Pitch, Roll
Acceleration :3 floats X, Y, Z
Velocity :3 floats X, Y, Z
Position :3 ints X, Y, Z (metres x 65536)
Game ID :1 int (optional ID - if specified in cfg.txt)
