# WH40K: Chaos Gate

Re-implementation of the WH40K binary.

**You must have a copy of the original game data to use this project**

WH40K.exe is the existing game engine

WH40K_TD.exe is the map editor. Allows things to be saved as .MAP or as .SMF
("Super Macro File")

This README is a grab-bag of miscellaneous information about file formats at
present. This is being migrated to the [Formats overview](doc/formats/index.md)
as a precursor to making this file useful!

No game yet, nothing even close. I'm in the very early stages of trying to
understand the various file formats. Until then, you can play WH40L: Chaos Gate
in a WinXP VM, disconnected from the internet. It doesn't need 3D rendering!



"Mission Setup" includes information about available squad types

From EquipDef.cpp Dumo: CEquipment we learn the following object types:

0. DELETED
1. WEAPON
2. GRENADE
3. MEDIPACK
4. SCANNER
5. GENESEED
6. CLIP
7. DOOR KEY
8. DOOR KEY
9. DOOR KEY
10. DOOR KEY

And we learn they can be "on"....

0. CHARACTER
1. VEHICLE
2. CANISTER


Hypothesis: Idx/WarHammer.idx points objects into bitmap data in Anim/WarHammer.ani

We can use WH40K_TD.exe and investigate reads of .idx followed by reads of .ani
to test this.

Obj/*.obj and Assign/*.asn files seem to have some identity

jungtil.asn references 18 frames (0-17) and a `jungtil.flc`, which is an AutoDesk format

We read jungtil.obj in about that number of blocks. Presumably each is a frame
in some format or another, but seemingly *not* FLC.

Here's our list of reads:

| Offset | Size | Gap | Purpose |
|--------|------|-----|---------|
|      0 |   32 |   0 | Main header
|     32 |  144 |   0 | Frame headers
|    176 |  463 |   0 | Frame 1
|    639 | 4466 |   0 | ...
|   5105 | 4437 |   0 |
|   9542 | 4468 |   0 |
|  14010 | 4470 |   0 |
|  18480 | 4461 |   0 |
|  22941 | 4472 |   0 |
|  27413 | 4464 |   0 |
|  31877 | 4477 |   0 |
|  36354 | 4473 |   0 |
|  40827 | 4472 |   0 |
|  45299 | 4437 |   0 |

|  63078 | 4329 |   0 |
|  67407 | 4329 |   0 | Frame 18

20 reads in total.

The following chunks are identical:

```
*   176 and 49736 (all  463-byte frames)
* 63078 and 67407 (all 4329-byte frames)
```

Here's the hex of the first 32 bytes:

```
         0  1  2  3   4  5  6  7   8  9  a  b   c  d  e  f
0x0000  12 00 00 00  20 00 00 00  90 00 00 00  B0 00 00 00
0x0010  88 17 01 00  00 00 00 00  00 00 00 00  00 00 00 00
```

* Offset 0 = 0x12 = 18 = the total number of frames ?
* Offset 4 = 0x20 = 32 = the size of the this block ?
* Offset 8 = 0x90 = 144 = the size of the next block ?
* Offset c = 0xB0 = 176 = the offset of the third read, or the size of the first two blocks combined ?

Need to unpack a few more objs to check what these numbers do. They could all
be 32-bit LE integers too.

0x10-0x13 as a 32-bit LE is 71560.

Total file size (71736) - 32 - 144 = 71560 = size of all frames combined

Obj/j_tree02.obj doesn't seem to adhere to these rules at all...

Then the next 144 bytes:

```
         0  1  2  3   4  5  6  7
0x0020  00 00 00 00  CF 01 00 00 =    0,  463

0x00A8  9F 06 01 00  E9 10 00 00
```

8 bytes per frame (8*18=144).

First four bytes in each line are the position relative to the start of the
first frame (i.e., minus the size of the first two blocks).

Last four bytes in each line are the total size of the frame, header + data.


Then there are 18 blocks of varying size. These must be the frames. First 32
bytes of all 18 blocks has a lot of similarities:

Remainder of each block is highly variable, so probably pixel data, and
(some of?) these 32 bytes are header data

bytes 4-7 could be dimension?

Tiles are 64x64 pixels (I think?), displayed in an isometric fashion, so I am
wrong or it's something else.

bytes 12 & 13 as LE 16-bit (or 12-15 as LE 32-bit) is always 24 bytes under full
block size.

Perhaps we have 24 bytes of header and that's the header-exclusive pixel data size?
Last 8 bits would then actually be the start of the image, but there's a lot
of similarity between them...

It smells a bit like a DIB: 

| Offset | Size | Example     | Purpose |
| 0      | 2    | D1 00 (209) | ? 
| 2      | 2    | 41 01 (321) | ?
| 4      | 2    | 80 00 (128) | Width? |
| 6      | 2    | 3F 00 (63)  | Height?
| 8      | 4    | 00 00 00 00 | Could be pitch / stride?
| 12     | 4    | D1 10 00 00 | Size of pixel data
| 16     | 4    | 00 00 00 00 | ?
| 20     | 4    | 00 00 00 00 | ?


Now, how to convert the pixel data to an image?!?!

Average bits per pixel seems to be less-than-1, e.g. for crates.obj:

```

```

So some form of compression? RLE?

How does WH40K_TD.EXE draw these?
