LOC.DAT

LOC.DAT has a row width of 20 bytes. There are a total of 50 records (not all of them necessarily used) for a fixed file size of 1,000 bytes. Most of this info is from NKF (thanks a lot) and some was ripped from Hatfarm / Chris Voss's great pages.

Structure

Offset (Decimal)	Offset (Hex)	Usage
0	0x00	Object type: 00 - Unused Entry 01 - Moving/Crashed Alien Ship 02 - X-COM Ship 03 - X-COM Base 04 - Alien Base 05 - Crash Site 06 - Landed UFO (unconfirmed in TFTD) 07 - Waypoint 08 - Terror Site (seems unused in TFTD) Extras for TFTD only: 81 - Port Attack 82 - Island Attack 83 - Passenger/Cargo Ship 84 - Artefact Site
1	0x01	Object table reference - Possible values - 00 to FF - Just a reference. This just shows how many there are of this type on the geoscape. If the object is either a UFO (Alien Ship for TFTD) or X-COM craft, then this is the index into CRAFT.DAT. If the object is an X-Com base, then this is the index into BASE.DAT and if it is an Alien Base this byte contains the race: UFO TFTD 0 = Sectoid Aquatoid 1 = Snakeman Gillman 2 = Ethereal Lobsterman 3 = Muton Tasoth 4 = Floater Mixed Crew
2-3	0x02-0x03	Horizontal coordinates or longitude (low bit then high bit respectively). 0 - 2880
4-5	0x04-0x05	Vertical coordinates or latitude (low bit then high bit respectively). -720 - 720
6-7	0x06-0x07	For crash site or terror site - countdown timer (in hours). For moving objects - how many game ticks (5s) have to pass until craft moved to next globe coordinate (cell_size div speed). NOTE: Ground UFOs are treated as moving objects, except for speed = 0.
8-9	0x08-0x09	Fractional part of how much is left to the next globe coordinate (cell_size mod speed), used only for moving objects.
10-11	0x0A-0x0B	Count suffix of the item, eg: Skyranger-1 or Crash Site-47. It appears to have no meaning for XCOM Bases, but for other types where it is set, 0B is the high byte for when you go over 255 UFO's or crafts, etc.
12-13	0x0C-0x0D	[UNUSED]
14	0x0E	Craft transfer mode: 0 = Not transferred 1 = In transfer 2 = Selected to transfer (temporary value)
15	0x0F	[UNUSED]
16-19	0x10-0x13	Globe object visiblity/mobility bitfield: 0 (value 1) Hidden object flag (unrevealed alien bases, xcom crafts at base, undetected UFOs) 1 (value 2) Moving object flag (UFOs, flying XCOM crafts except for when patrolling). 2 (value 4) Targeted UFO flag (set to 1 when alien craft targeted). Used for UFO decode menu popup when UFO craft reappears.
