+# Mods
+
+A mod is a folder of Halo PC tag files that the game plays over a map's own
+tags on your machine, as a resource pack does: sounds (a high-res audio
+pack), bitmaps (a texture pack, a HUD redraw), text (a translation) and
+models (higher-detail weapons, vehicles and scenery). Only the machine that
+has a mod plays it. Nothing of a mod is sent to another machine, and a mod
+changes nothing that the machines of a network game must agree on, so you
+can play with mods in any game, with players who have other mods or none. (A host's mod sounds of other lengths change how long
+the host's scripts and AI wait for dialogue to end; the host decides those
+for every machine, so they still agree.)
+
+The game's code is `port/linux/game/mods.c` (with `mod_sounds.c`,
+`mod_bitmaps.c`, `mod_strings.c` and `mod_models.c`, one for each kind of
+tag) and `port/linux/src/port_mods.c` (the mods folder and its files).
+
+## A mod's folder
+
+The mods are in the `mods` folder of the data root (the folder with
+`maps/`; on Android the app's data folder, on the web the browser's storage
+for the site). Each mod is a folder in it, with a `mod.toml` and a `tags`
+folder:
+
+```
+mods/
+  hd_audio/
+    mod.toml
+    tags/
+      sound/sfx/weapons/assault rifle/fire.sound
+      sound/dialog/...
+  german/
+    mod.toml
+    tags/
+      ui/hud/hud_item_messages.unicode_string_list
+```
+
+The files in `tags` have the paths of the tags they replace: a tag's name,
+then its group's extension, as the Halo Editing Kit and Invader keep them.
+`tags/sound/sfx/weapons/assault rifle/fire.sound` replaces the sound tag
+`sound\sfx\weapons\assault rifle\fire` of every map that has one. Names are
+not case-sensitive. The game only looks up the names of the map's tags among
+a mod's files: a mod cannot add tags, and no tag name of a map makes a path
+outside the mod.
+
+`mod.toml` says what the mod is. Every key is optional:
+
+```toml
+name = "High-res audio"       # what the Mods menu shows (else the folder's name)
+id = "hd_audio"               # what other mods name it by (else the folder's name)
+version = "1.0"
+authors = ["Someone", "Someone else"]   # or one string
+description = "The game's sounds at 44 kHz"
+maps = ["a10", "bloodgulch"]  # the maps it is for, by their files' names (else every map)
+load_after = ["hd_textures"]  # mods it plays over: they load before it
+load_before = ["fixes"]       # mods that play over it: they load after it
+incompatible = ["other_audio"]  # mods it cannot be played with
+format = 1                    # the mods' format it is made for
+```
+
+`load_after`, `load_before` and `incompatible` name other mods by their `id`
+or their folder's name, not case-sensitive. A mod they name that is not in
+the mods folder is passed over. `maps = []` is every map.
+
+A folder without `mod.toml` is not a mod. A mod made for a later `format`
+than the build's, or whose `maps` names no map, is not played. The game
+logs anything else wrong in `mod.toml` (an unknown key, a value of the
+wrong type) and uses the rest; a `mod.toml` that is not TOML at all is
+logged, and the mod played without what it says.
+
+The game's log is its output: the terminal on Linux, `halo.log` beside
+`halo.exe` on Windows, logcat on Android, and the page's log on the web.
+
+Limits: 256 mods, folder names of 63 bytes at most, 262144 files in all, 24
+folders deep under `tags`, and 64 maps in a mod's `maps`.
+
+## The load order
+
+Every mod in the mods folder is on until you turn it off. The mods load in
+an order, and where two mods have a file for the same tag, the one loaded
+later plays.
+
+- The default order is the folders' names in alphabetical order (not
+  case-sensitive), except that the mods a mod must load after (those it
+  asks to load after, and those that ask to load before it) are taken to
+  just before it. Mods that ask in a ring (a after b, b after a) load
+  alphabetically, and the game's log says so.
+- The main menu's **Mods** (in the PC version's menus, `display.menus =
+  "pc"`, the default) is laid out as the game lobby is: the mods on the
+  left as a resource pack list has them, the one at the top playing over
+  all those below it (the load order upside down: the mod loaded last is at
+  the top), and the chosen mod's details in the frame on the right (its
+  name, what is wrong with it, whether it is on, its priority, 1 the top,
+  and its version, authors, folder, maps and description). Choosing a mod
+  (A, or a click on the chosen one: the first click chooses it) turns it on
+  or off (ON, OFF); left and right, or **Move up** and **Move down**, move
+  the chosen mod (up: over one more mod). **OK** keeps the order and plays
+  it at once (on a map that is loaded, too); **Cancel** leaves it as it was.
+- A warning sign beside a mod means it is on the wrong side of a mod it
+  asks to load before or after (both on): a mod that loads after another is
+  above it in the menu. A red cross means a mod that is on says it cannot be
+  played with this one, or that it cannot be played at all (made for a later
+  build, or its `maps` names none): it stays off. The details say which.
+
+The menu keeps the order, and the mods turned off, in `mods/load_order.toml`,
+by the mods' folders' names:
+
+```toml
+order = ["german", "hd_audio", "hd_textures"]
+disabled = ["hd_textures"]
+```
+
+A mod added to the folder later is put where the default order puts it,
+after the mod before it there (but on the side it asks for of the mods it
+names), and is on. A mod gone from the folder is left out. When the file
+cannot be written, the game says so in its log and keeps the order until it
+quits.
+
+### Mods that cannot be played together
+
+When a mod that is on names another that is on as `incompatible`, the game
+asks as it starts, before the window opens:
+
+- **Play anyway** plays them all (closing the box does too);
+- **Turn off ...** turns off the mods named as incompatible (if mod A says
+  it cannot be played with mod B, B is turned off), and keeps that in
+  `load_order.toml`;
+- **Quit** closes the game.
+
+The Mods menu turns them on again. On the web, **Quit** starts the page
+again. A run nobody watches (`debug.hidden_window`, `debug.null_renderer`,
+`debug.exit_after` or `debug.network_test`) is not asked: it plays them all,
+and the game's log says which conflict.
+
+At the console:
+
+| Command | What it does |
+| --- | --- |
+| `mods_list` | Lists the mods in the mods folder in their load order, and which are on, then how many of the map's string lists, bitmaps, sounds and models the mods play. |
+| `mods_reload` | Finds the mods again and reads their files again: a changed file is read again (one that now fails a check leaves what was played before), a new one is played, and the map's tag comes back for a file that is gone. If a sound changed, all sounds stop. It does nothing while `mods_enable false`. |
+| `mods_enable false` | Plays the map's own tags until `mods_enable true` or the next map. |
+
+These commands work in any game, a client's too: they change nothing of the
+game.
+
+### Getting a mod onto each platform
+
+- **Linux, Windows**: put the mod's folder in `mods/` next to `maps/`.
+- **Android**: put it in `mods/` in the app's data folder,
+  `/sdcard/Android/data/com.halo.decomp/files/mods`, for example with
+  `adb push hd_audio /sdcard/Android/data/com.halo.decomp/files/mods/`.
+- **Web**: on the page, **Mods**, **Add a mod folder…** copies a mod's
+  `mod.toml` and `tags` folder into the browser's storage for the site.
+  **Remove** deletes it again.
+
+## What a mod can replace
+
+The game plays these groups from a mod. It does not read the files of any
+other group (a `.weapon`, `.vehicle`, `.model_collision_geometry` or
+`.scenario`, for example): they would change what the machines of a network
+game must agree on.
+
+| Group | Extension | What it is |
+| --- | --- | --- |
+| Sound | `.sound` | Sounds, music and dialogue |
+| Bitmap | `.bitmap` | Textures, sprites, the HUD's pictures |
+| Unicode string list | `.unicode_string_list` | The text the game shows |
+| String list | `.string_list` | Other text |
+| Model | `.gbxmodel` (Halo PC's), `.model` (the Xbox's) | What objects look like: weapons, first-person weapons and arms, vehicles, scenery, characters |
+
+A file must be a Halo PC tag file of its group, as the Halo Editing Kit's
+tools and Invader write them (a model also as `invader-extract` writes an
+Xbox map's: `.model`). The game checks every count, size and offset
+in it against the file, and every value against what the game reads, before
+it uses the file. A file that fails a check is left out (the map's tag
+plays), and `debug.txt` and the console say why.
+
+### Sounds
+
+- The samples can be 16-bit PCM, Xbox ADPCM or Ogg Vorbis, mono or stereo,
+  at 22 or 44 kHz. The game converts them to the Xbox ADPCM that it plays,
+  as it does for Custom Edition maps: mono at 22 kHz, stereo at its own rate.
+- Empty values are filled in as a map's build fills them in: the defaults
+  of the sound's class, the playback rates and the bend.
+- A sound must have permutations: a file with an empty pitch range (some
+  Halo PC translations have them) is left out.
+- A permutation must fit in a block of the sound cache (one sound's samples:
+  `MAXIMUM_SOUND_DATA_SIZE`).
+
+### Bitmaps
+
+- A bitmap's types and formats are those the game draws: 2D, 3D and cube
+  maps; A8, Y8, AY8, A8Y8, R5G6B5, A1R5G5B5, A4R4G4B4, X8R8G8B8, A8R8G8B8,
+  DXT1, DXT3, DXT5 and P8 bump. Sides are 4096 at most (512 for a 3D
+  bitmap). A bitmap that is not a power of two on each side is drawn
+  linear, as a Custom Edition map's is: it must be an uncompressed 2D
+  bitmap.
+- One bitmap's pixels may take a quarter of the texture cache: 64 MB on
+  Linux and Windows, 5.5 MB on Android and the web (a 2048 x 2048 DXT5 with
+  its mipmaps fits on all of them).
+- A bitmap replaces the map's bitmap of its name, and the map's other tags
+  use it as the map's: it must have at least as many bitmaps, of the same
+  types, and as many sequences, each with at least as many sprites. It can
+  be larger: a redraw at twice the size is drawn at the map's size, sharper.
+- The HUD draws a bitmap at its own size. So for each HUD element that draws
+  a mod's bitmap, the game scales the element by the map's size of what it
+  draws (its sprite, or with no sprites its bitmap) to the mod's, when that
+  is the same ratio for all of them. A bitmap the HUD draws that is not the
+  map's redrawn so (Halo PC's HUD bitmaps lay their sprites out to other
+  sizes) is left out. The HUD's digits can be the map's size or twice it.
+- The menus draw a bitmap in their widgets' bounds, whatever its size.
+- Halo PC keeps the channels of a model shader's multipurpose maps and of
+  the HUD's meters in another order than the Xbox. The game finds those
+  bitmaps among the mod's and draws them in the Xbox's order, as it does for
+  Custom Edition maps (`custom_edition_bitmaps.c`).
+- The pixels are read from the file when the texture cache loads them, not
+  kept in memory.
+
+### Text
+
+- A list keeps the map's number of strings: a mod's strings past it are
+  left out, and the map's own strings stay where the mod's list is shorter.
+- The game uses many strings as the format of what it prints
+  (`%s was killed by %s`). A mod's string replaces the map's only if it has
+  the same conversions in the same order (`%s`, `%d`, ...); otherwise the
+  map's string stays. A translation keeps the conversions of the original.
+- Unicode strings are UTF-16, as the tool writes them.
+- The main menu is the port's own (the PC version's menus, `port/assets/menus`),
+  whose text is in tags named `pc\...`. A mod's `ui\shell` lists change the
+  Xbox's menus (`display.menus = "xbox"`) and the text shown while playing
+  (HUD messages, the multiplayer messages, the pause menu).
+
+### Models
+
+A model is more than what is drawn: its nodes (its skeleton) are what its
+animations move, its markers are where projectiles leave a weapon, where a
+unit sits and where things attach, and its regions and permutations are what
+damage and an object's variant choose among. The machines of a network game
+agree on those, so a mod's model must have the map's:
+
+- the same nodes: their names, hierarchy and default positions;
+- the same markers: their names, regions, permutations, nodes, positions
+  and rotations (on the model's permutations, as the Halo Editing Kit keeps
+  them, or on the model, as a map does);
+- the same regions and permutations: their names and flags.
+
+Positions and rotations may differ from the map's by 0.001 at most (a model
+exported again is not always bit for bit the map's). Only what is drawn is
+the mod's: the geometries, their parts and vertices, which geometry each
+permutation draws at each detail level, the detail levels' cutoffs, the
+base map's scale, and which shaders each part is drawn with. A detail level
+the map draws must draw one of the mod's geometries, and one the map draws
+nothing at stays so. Every shader must be one the map has (a mod cannot add
+tags); a mod's bitmaps can redraw them.
+
+The model is checked against each map's own model of its name as that map
+loads. On a map whose model of that name has other nodes, markers or
+regions (a custom map's own assault rifle, say), or lacks a shader the mod
+names, the mod's model is left out and the map's drawn; the mod's other
+files still play there. `maps` in `mod.toml` keeps a mod to the maps it is
+made for.
+
+- Where a mod has both, its `.gbxmodel` plays; otherwise the file of the mod
+  loaded later, whichever its format.
+- What the tool works out as it builds a map is worked out as it does: a
+  part's strip is its triangles block, its centroid's nodes are its most
+  weighted, its links of 0 to the parts drawn before and after it are none,
+  a base map scale of 0 is 1, and a model whose tag asks for it has the
+  normals of its vertices that share a position blended. The vertices are
+  compressed as the game draws them.
+- A part's links to the parts drawn before and after it (for transparency)
+  must not go round.
+- A model of 44 nodes or more (the renderer skins 43 at once; only Custom
+  Edition maps' have so many) is drawn a part's own nodes at a time, as a
+  Custom Edition map's is: a part's vertices may name 22 nodes at most.
+- The collision geometry, the animations and the object's tag are the map's:
+  a larger weapon still hits and is hit where the map's does, and an object
+  is still left undrawn by the map's bounds of it (a much larger model may
+  vanish at the screen's edges).
+- Every model made from a file is kept until the map changes, a file edited
+  and read again by `mods_reload` too, and counts against the mods' memory.
+
+### Shaders
+
+A model's parts can be drawn with a shader of every group Halo PC has but
+one: `shader_transparent_chicago_extended`, which Gearbox added for Halo PC.
+The Xbox game does not have it, so do not use it: use a
+`shader_transparent_chicago` shader instead. (A Custom Edition map's
+chicago extended shaders become chicago shaders as the map loads, keeping
+only their four-stage maps: see
+[custom_edition_caches.md](custom_edition_caches.md).) As for every
+shader, it must be one the map has.
+
+## Making a mod
+
+1. Get the tags you want to change as tag files. `invader-extract` extracts
+   them from a map, and the Halo Editing Kit's tags are Halo PC's own.
+2. Change them with the Halo Editing Kit or Invader (`invader-bitmap`,
+   `invader-sound` and `invader-model` build bitmaps, sounds and models from
+   images, audio files and JMS files). Keep each tag's name.
+3. Put them in `tags/` of a folder in `mods/`, with a `mod.toml`.
+4. Load a map (a new mod is on). `mods_reload` at the console reads the
+   files again as you change them, without loading the map again.
+
+`debug.txt` has a line for every file the game leaves out, and why, and a
+summary of what each kind of tag plays from the mods:
+
+```
+mods: 9 string lists from their files (9 new), 0 given back, 0 left out
+mods: 66 HUD placements scaled to draw larger bitmaps at the map's size
+mods: 354 bitmaps from their files (354 new), 0 given back, 6 left out
+mods: 313 sounds from their files (313 new), 0 given back, 2 left out
+mods: 4 models from their files (4 new), 0 given back, 1 left out
+```
+
+## How it operates
+
+- When a map's tags load, at `mods_reload` and at the Mods menu's **OK**,
+  the game lists the files of the mods that are on, once, in a table of
+  their tag paths. Each of the map's sound, bitmap, string list and model
+  tags is looked up in it.
+- A tag replaced by a mod takes the file's values in place, so everything
+  that holds the tag keeps it, and the map's own values come back when the
+  file goes. A sound playing or a texture in the cache is never changed
+  under the game: before a reload changes anything, the sounds stop and the
+  caches let go of what they hold.
+- The mods' tags keep at most 512 MB in memory (192 MB on Android and the
+  web): their files, their sounds' samples, their bitmaps' tags and their
+  models' geometry.
+- A Custom Edition map takes mods as an Xbox map does.
