Community Project: Fill in the Unknowns

[grimdoomer]

No this is not another plugin thread. This thread is to map out all other map data then plugins. The reason we can't do to much is because there are various areas of the map file that we don't understand completely. There are people who have a better understanding of the map file, but those people are no longer around. So let this be a layout for any one who wants to learn more about the map file. So I'll take all the known info and add any info I found to it. Then any info posted I will add. I hope this gets somewhere, if not then let it be a layout for future apps. For those of you who think you can't contribute, you can. There are various tags who's meta reflects other tags, most of which are not filled in. C code is fine but please do not give us a 3 page method. Keep it sort and simple When posting an found variable, please give its map section, and offset.

  Index Layout:
    - Header
    - Tag List
    - Object Index

  Tag List:
    This list contains all used tags in the map file, and defines their object hierarchy. 
    This allows the engine to know for example, that all vehicles are a sub class of the 
    unit class, which is a sub class of the object class. I believe the wildcard tags are 
    used as a way of using the primary tag without its parents, though this is just speculation. - Iron Forge

  Object Index:
    The object index is a recursively-constructed collection defining all objects in the map.
    The objects identifier is defined here, which is used to reference the object from all other
    areas of the map file. The identifier is composed of two short values, each are incremented
    equally throughout the index. The meta offset is a secondary magic offset which points to
    the beginning of the objects meta. - Iron Forge

     public string Class; // 4 reversed letters.
     public int RawMetaOffset;
     public int MetaOffset; // RawMetaOffset - SecondaryMagic

  }

Raw Offsets

Code: Select all

  Notes:
    Raw offsets in Halo 2 have no magic applied to them. However, they can reference the 
    current map file, or the three shared files. To do this, it reserves the two most significant 
    (highest) bits to define the referencing file. These are defined as: 002 being local file, 012 
    being mainmenu.map, 102 being shared.map, and 112 being single_player_shared.map.

    When referencing a raw offset, one should first determine the file being referenced, remove 
    those two bits from the offset value (and with 0x3FFFFFFF), and then seek to that offset in
    the correct file to find the referenced data. Given the size of the shared files, it is possible that
    the third most significant bit is also reserved for sharing new downloadable content in the future, 
    but this would just be speculation. - Iron Forge

Crazy

Code: Select all

  Notes:
    Although nothing is really know about the crazy table, it is just a table of some random
    tag paths. It can be accessed by the offsets in the header.

Bitmap Raw

Code: Select all

  Notes:
    Bitmaps in Halo 2 are standard DDS images. Each bitmap is allowed 6 levels of detail(LODs) 
    although only the first 3 are used; each having their own set of mip maps. Bitmaps are still 
    swizzled (a method of faster memory copies).

Coconuts (Ugh!)

Code: Select all

  Notes:
    The Coconuts tag has a lot of reflexives that organize sounds. It also has 1 reflexive with model Raw
    details. Kudos to Iron Forge for being the only person to ever map anything in this tag. I have since
    then add some new things as well as clean it up. This tag is based on reflexives with index's into more
    reflexives. The base reflexive is Sound Permutations, this has the index to Sound Names, and Sound Choices.
    Sound Names is just a stringid with a name for that sound, Sound Choices is a list of possible sound files
    to play. Each one indexing a Sound Raw Chunk. There is also a Model Raw reflexive, my guess is since the
    crazy tag is ALWAYS the last tag, the engine can render all models without reading every model tag.
    I also assume there is some sort of tag pointer in that reflexive or vice versa. The Coconuts tag also has a lot
    of loneid's to itself, not sure why but they are important to fix when adding new tags to the map.

Sound Raw

Code: Select all

  Notes:
    The sound tag is very small 20 bytes. In it it contains indexes to loads of data. Sound Raw
    is based on 3 main compressions ADPMC, OGG? and WMA, and 3 formats Mono 22050kbps,
    Stero 44100kbps, and WMA Specific. It also contains an index into the Sound Permutations
    reflexive in the coconuts tag. From there you can get all the sound chunks. It also contains
    indexes into other unknown reflexives.

    Sounds were probably the most enjoyable piece of Halo 2 to work on. They entwine with 
    an “ugh!” object named “I’ve got a lovely bunch of coconuts”, a song done by the amazing
    comedic group Monty Python. I cannot help but believe this system was done as an easter 
    egg designed just for me as “the curious modder”. To Bungie, I thank you (unless of course 
    this was designed to keep us from removing sounds, in which case I sincerely apologize.) - Iron Forge

Model Raw

Code: Select all

  Notes: 
  Model Raw is based on 7 blocks, deal with compressed verticies. Currently
  there is only 1 Unknown resource block. 

  Models in Halo 2 use a compressed format based on a bounding box.  This bounding 
  box can be found in the first reflexive of the model meta. Using its constraints for each 
  value relevant to the models, the uncompressed value can be found using the formula
  (((shortValue + 32768) / 65535) * (maxValue – minValue)) + minValue.

  The model raw data block now contains a header, footer, and several resource chunks. 
  The header contains information regarding how many chunks are in each resource block, 
  allowing you to determine which block contains the information needed (for example, if a 
  given block has 0 chunks, then it will not have a corresponding resource block). The important 
  resource blocks are the mesh information block (containing mesh information), the indices 
  block (containing the indices for the triangle strip), the vertices block (containing at minimum
  3 shorts defining the x, y, and z of the vertices), the UV map (containing the compressed 
  UV points.), and the bone map. - Iron Forge

    Decorator raw one of the only completely mapped raw formats, yet one of the least

  Notes:
    Particle mode raw is almost exactly the same as decorator raw. All the info

    The layout is almost the same(it could be the same, I have yet to make a PRMT
    viewer so I don't know), the only difference is that the tangents and binormals
    are switched.

    Weather raw surprisingly has NEVER been researched in any way, at least not to my knowledge. 
    So I decided to take a looksy yesterday. It seems simple 2 resource blocks, but each one 
    consists of blocks of 4 floats. Which I don't understand, so I'll leave that up to someone smarter
    at models then me. Here is the basic layout for you guys.

Animation Raw

Code: Select all

  Notes:
    Almost nothing is know about animation raw, although one team has figured it out
    I doubt they will release anything. I have gather some info based on their findings.

    Firstly, animations use 9 codecs, all of them i believe have different compression 
    methods, and some have no compression at all. Halo 2 Vista's map editor dumps a 
    text file called animation_compression_stats.txt which contains a lot of valuable 
    information regarding animation compression.  - Choking Victim

    The text file also contains a small diagram of individual animations within an animation 
    tag. The below picture is a diagram of the warthog animation. 
    http://zteam.halotrialmods.org/images/1-16-08/anim_compression.jpg 
    This diagram shows the animations size within the raw data, static node information 
    (nodes that don't move throughout an animation), and normal animation information. - Choking Victim

Collision

  Notes:
    Collision has no raw data per say, it is all in the meta. It is simple verticies with bounding
    spheres. It is pretty much completed though.

Physics Model

Code: Select all

  Notes:
    Thanks to one of the best modders Neodos, who has recently retired, we can have custom
    physics models. Although I do not know much, I do remember some of what he told me. Physics
    Models are based on bounding boxes around sections of the model. At a second glance these 
    could be rendered very easily. The important reflexive that allows for collision in-game is
    Physics Boxes. I believe JacksonCougar could offer more info.

Wow thats a lot of info Any ways, I'll get to BSP and Lightmap info later. I need some time to think. Please feel free to jump in and post anything to help out. I can also provide raw data samples if needed. I'm on AIM almost 24/7 which can be a bad thing, but any way, I'm there if you need info or w/e feel free to IM me.

[grimdoomer]

Wow not even one reply, what a shame.

This is halomods there's no modders there's only people talking about how much they know and can do, also this is great research but pretty much for programmers, there's only you and Jackson that are actually working on modding apps.

I'm working on a program too...

I'm working on something as well.

[xXFeRcHoXx]

i like your App, Eaton, i remember when your app was an alpha... already has plugins or somewhat?

EDIT: nice UI

I'm trying to learn to parse XML so I can load data from plugins into the Reference Viewer. Should be done soon. Spent a lot of time and money on the UI. And that is what makes it unique.
