Heading represents 360 degrees in 256 values.

Heading = (heading_in_degrees + 180) * 256 / 360

• 128 : heading of zero
• 192 : heading of 90 degrees
• 0 : heading of 180 degrees
• 64 : heading of -90 degrees

Object index

The first valid object index is 4 (AXO_CHALK_LINE). The gaps are to allow for future objects. Valid object indices are all less than 192.

Position (1 metre = 16)

Position (1 metre = 16)

About Zbyte, the approximate altitude :

LFS does contact checks to place objects accurately on the ground.

For output purposes : Zbyte indicates the approximate altitude with a value from 0 to 240 (60 metres).

For input purposes : The ground check is performed with a test ray starting from 2 metres above Zbyte. Using a value lower than 240 allows objects to be placed on the road below a bridge, for example. If you are creating objects from scratch and you are not sure of the approximate altitude, you can set Zbyte to its maximum value (240). This will place the object on the first physical surface detected below that point.
