This is probably going to get screwed up by google's word rap.. but
i'm going to post any way..
you can also find this information at
http://www.x-com.co.uk/forums/index.php?showtopic=1457
in a somwhat more readable format.
Understanding Map Control Data (MCD) Files
The MCD files are used by both UFO and TFTD to defined the TILE's used
in tactical to form the physical and visual battle map
Understanding the format of the MCD files allows us to create our own
TERRAIN and TILE SETS's and ultimately, new MAP SET's
The goal of this paper is to help the moding community understand how
to edit (or write utilities to edit) the MCD files in the UFO and TFTD
terrain directory.
all tho I will touch on PCK files I will not go in depth on their
format as their are plenty of utilities to edit them.
Each MCD file is named the same as the PCK and TAB files that it uses
graphics from. MCD files contain variable number of MCD records. Each
record is 62 bytes long and have the following format
typedef struct mcdentry
{
unsigned char Frame[8]; //Each frame is an index into the
____.TAB file;
// The frames is the visual part of the Tile,
// If all frames are the same than it's a static image
otherwise it's animated
unsigned char LOFT[12]; //Line Of Fire Template, The 12
levels of references into GEODATA\LOFTEMPS.DAT
// used to describe the 3D phisical make up of the
Tile
// (more on this later)
short int ScanG; //an index into the
GEODATA\SCANG.DAT (4x4 bmp images used for the overhead map)
// DaiShiva's PCKView.NET editor
can be used to view thease images
unsigned char u161D[8]; // UNKNOWN..
unsigned char UFODoor; //[On/OFF flag]If it's a UFO door
it uses only Frame[0] until it is walked through,
// then it animates once and
becomes OpenMCD. It changes back at the end of the turn
unsigned char StopLOS; //[On/Off flag]You cannot see
through this tile. (how it blocks is based on TileType)
unsigned char NoFloor; //[On/Off flag]If 1, then a
non-flying unit can't stand here (only valid on floor TileTypes)
unsigned char BigWall; //[On/Off flag]It's an object
(tile type 3), but it acts like a wall
// Used most often for unwalkable Tiles. IE. Tables
and Solid Rock
unsigned char Gravlift; //[On/Off flag] The up/down of a
grav lift is determined if their is
// another gravlift above or
below in the MAP file
unsigned char Door; //[On/Off flag]It's a human style
door--you walk through it and it changes to OpenMCD
unsigned char BlockFire; //[On/Off flag]If 1, fire won't
go through the tile
unsigned char BlockSmoke; //[On/Off flag]If 1, smoke won't
go through the tile
unsigned char u26; // UNKNOWN...
unsigned char TUWalk; //The number of TUs required to
pass the tile while walking.
// An 0xFF (255) means it's
unpassable.
unsigned char TUFly; //The number of TUs required to
fly through tile
// 0xFF means it's impassable!
unsigned char TUSlide; //Tu's for Sliding things like
snakemen and silacoids
unsigned char Armour; //The higher this is the less
likely it is that a weapon will destroy
// this tile when it's hit.
unsigned char HEBlock; //How much of an explosion this
tile will block
unsigned char DieMCD; //If the terrain is destroyed, it
becomes this MCD entry.
unsigned char Flammable; //How flammable it is (the higher
the harder it is to set aflame)
unsigned char OpenMCD; //If "Door" or "UFODoor" is on,
then when a unit walks through it the door it changes to this MCD
entery.
unsigned char u2F; // UNKNOWN..
signed char VDisplace; //When a unit or object is on
this tile, the unit is shifted by this number of pixels
unsigned char SubtractY; //The pck images are drawn this
many pixels lower when displayed. (used for hills)
unsigned char u32; // UNKNOWN..
unsigned char BlockLight; //The amount of light it blocks,
from 0 to 10
unsigned char SoundFX; //The Sound Effect set to choose
from when footsteps are on the tile
// This is mostlikly an index to
the .CAT file RAW wave
unsigned char TileType; //This is the type of tile it is
meant to be --
// 0=floor, 1=west wall, 2=north
wall, 3=object . When this type of tile is in the
// DieMCD or OpenMCD flags, this
value is added to the tile coordinate to determine
// the byte in which the tile
type should be written.
unsigned char HEType; //0=HE 1=Smoke
unsigned char HEStrength; //The strength of the explosion
caused when it's destroyed. 0 means no explosion.
unsigned char SmokeBlockage; //? Not sure about this ...
unsigned char Fuel; //The number of turns the tile
will burn when set aflame
unsigned char LightSource; //The amount of light this tile
produces
unsigned char TypeProperties;//The special properties of the
tile (like Aqua plastics.. or Synom device)
// This effects what is salvage
from a UFO/USO or base at the end of combat.
// some settings are used for
combat Win conditions (use MTT_nnn and MT_nnn )
unsigned char u3C3D[2]; // UNKNOWN..

Line Of Fire Teplates (LOFT)
The LOFT's are stored in loftemps.dat found in the GEODATA dir in UFO
and GEODATA and TERRAIN in TFTD
(I believe the TERRAIN one is not used)
for both games these files are exactly the same. It contains 112 LOFT
entries (0 through 111).
a LOFT entry is 16 unsigned shorts used as a binary mask. this makes a
16x16 bit square.
win 1 being a solid object and 0 being empty space.
for example. Entery number 4:
004: /----------------\

not very readable. so I'm going to display them with # for 1 and . for
0
(requires a fixed width font)

This defines a solid circle in the middle of the tile.
Each MCD uses 12 LOFTS (starting at the bottom) to create a 16x16x12
bit mask
lets look at a simple object. the barrel from a TFTD Port mission
File: port01.mcd
Entery number 93
Offset: 0x00001686:
5D 5D 5D 5D 5D 5D 5D 5D
04 04 04 04 04 04 04 04 00 00 00 00
0047
04 00 18 54 04 00 25 54 00 00 00 01 00 00 00 01
03 FF FF FF 0A 0A 00 0A 00 00 EE 00 00 00 04 03
00 50 00 03 00 00 00 00
The first line is the 8 images.. all the same because this is not an
animation
The second line is our LOFT enterys. the first eight are 04. the
circle shown above.
the last four are 00.

as you can see it's empty space. This shows that the barel is not as
tall as the whole TILE.
Lets look at a more complex example
Tthe stone staircase along the warf of the TFTD Port terrain
Entery: 20

As you can see the physical shape of the stairs obvious in the solid
parts of the LOFT masks
I hope this information will help others in modifying Terrains for new
maps in UFO and TFTD
Apendix1:
cense there is not easy to use editor for LOFT files I'm including all
112 entries below
