variable

Array[X,Y,Z] (see below)

Array format

Array[X,Y,Z] is a 3-dimensional array *of Objects* with height X, width Y, and depth Z. The type of data contained within the Object varies by the Instance ID of the file.

_______________________________________________________________

Instance ID 0x00

• It is for the location of floor tiling.

DWORD

Count X [offset ranges: 81-84 / 0x51-0x54] (Width = n1 x 10)

DWORD

Count Y [offset ranges: 85-88 / 0x55-0x58] (Height = n2 x 10)

DWORD

Count Z [offset ranges: 89-92 / 0x59-0x5C] (number of array layers/levels/stories)

Data storage format

Note: W = West; N = North; E = East; S = South; "?" = Unknown where Known values of "?" = 0

Format = W? N? E? S? , where W, N, E, S = any of the floor tile map reference number found in String Map file instance 0x0E

• Based on the pattern, this is apparently the array for floor tile pattern and the value may be the floor tile map reference number (found in instance 0x0E of String Map (SMAP; CAC4FC40) files); 0x0000 = untiled;

Instance ID 0x01

• It is for the "height" location of the grid points of a grid layer/array/level.

DWORD

Count X [offset ranges: 81-84 / 0x51-0x54] (Width = [n1 x 10] + 1)

(number of grid point along the Width)

DWORD

Count Y [offset ranges: 85-88 / 0x55-0x58] (Height = [n2 x 10] + 1)

(number of grid point along the Height)

DWORD

Count Z [offset ranges: 89-92 / 0x59-0x5C] (number of array layers/levels/stories)

Data storage format

Float (in singles)

• Functions:

• • 1. To store arrays of the height values of grid points in singles. And, the layer/story/level of grid point is presumed probably based on values of W, H and layer/story/level probably partly dependent on the same 3D array instance file.
  • 2. Every standard level height is 16-click-high/16-step-high, and it has a value of 3 in singles. In other words, each click (in terms of elevation tools)/step (in terms of modular stairs) is 0.1875 in singles.
  • 3. Negative value can exist in singles and later values can be smaller than the previous values for every layer/story/level as V!ND!CARE's <4-click wall tutorial suggests.
  • 4. if there's a swim pool, the underground layer of grid points will be placed earlier than the ground lot origin.

Instance ID 0x03

DWORD

• Guesses: This may be a road pattern array or tiled grid array?
  • (Lot origin is the 'corner point' the shadow points at, and it is the origin a lot rotates at.)
    • eg1 = 30 repeats of 20(0x00)-10(0x01) for a lot (Width=30 & Height=30; lot origin @ right & back corner; an empty 3x2 lot)
    • eg2 = 30 repeats of 10(0x01)-20(0x00) for a lot (Width=30 & Height=30; lot origin @ left & front corner; an empty 3x2 lot)
    • eg3 = 600(0x00)-300(0x01) for a lot (Width=30 & Height=30; lot origin @ left & back corner; an empty 3x2 lot)
    • eg4 = 300(0x01)-600(0x00) for a lot (Width=30 & Height=30; lot origin @ right & front corner; an empty 3x2 lot)
    • eg5 = 300(0x01)-900(0x00) for a lot (Width=40 & Height=30; lot origin @ right & front corner; an empty 3x3 lot)
    • eg6 = 400(0x01)-1200(0x00) for a lot (Width=40 & Height=40; lot origin @ right & front corner; an empty 4x3 lot)

Instance ID 0x09, 0x0A, or 0x0B

• They are related to a closed room as data are added into them upon formation of a closed room. Values for room (light, load, place) matches values in instances 0x0B, 0x0A and 0x09 respectively. Not all three will be used or marked when a given closed room is made. The raise in numeric value is accumulative dependent on how many times one is used along the history of undeleted closed rooms in a lot.
  • for instance, a wall1 room was made first, it happened all three were employed, then (1,1,1) resulted inside such room. Thirdly, a foundation block was made, (2,2,2) resulted for the inside of the foundation. Fourthly, a room of screen deck was made, (3,3,0) resulted inside the screen room.

Fifthly, a room of column deck was formed, (0,4,0) resulted inside it. Sixthly, a roof room was built , (4,0,3) resulted inside the attic room. Seventhly, a wall1 room was built, (5,5,4) resulted inside the room. Note, the unclosed rooms and the "outside" had (0,0,0) for the three of "room".
