Format

The format is near identical to its successor, RRR, in San Andreas. Each entry is 28 bytes in size, with the following format:

Offset (decimal)	Size (in bytes)	Type	Description	Notes
00	02	INT16	velocity in direction X	Divide by 16383.5 to get floating point values
02	02	INT16	velocity in direction Y	Divide by 16383.5 to get floating point values
04	02	INT16	velocity in direction Z	Divide by 16383.5 to get floating point values
06	01	INT8	XYZ.right.x	Divide by 127.0 to get floating point values
07	01	INT8	XYZ.right.y	Divide by 127.0 to get floating point values
08	01	INT8	XYZ.right.z	Divide by 127.0 to get floating point values
09	01	INT8	XYZ.top.x	Divide by 127.0 to get floating point values
10	01	INT8	XYZ.top.y	Divide by 127.0 to get floating point values
11	01	INT8	XYZ.top.z	Divide by 127.0 to get floating point values
12	01	INT8	Steering Angle	Divide by 20.0 to get floating point values
13	01	INT8	Gas Pedal Power	Divide by 100.0 to get floating point values
14	01	INT8	Brake Pedal Power	Divide by 100.0 to get floating point values
15	01	INT8	Handbrake used flag	Bool: 1 = true, 0 = false
16	04	FLOAT	XYZ.pos.x	Standard float
20	04	FLOAT	XYZ.pos.y	Standard float
