From 260dd423c99eb4339b94e07cb25ea573b095c33c Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Sun, 25 Oct 2026 14:30:42 +0000 Subject: [PATCH 001/206] Keep sprint as a state so a sprint-jump keeps its forward impulse MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PlayerInput was rewriting the server sprint flag from the Ctrl and forward keys. That flag is synced back onto the client, and jumpFromGround adds its 0.2 look-direction impulse only while the flag is set, so releasing Ctrl before the jump (or double-tapping forward) produced a plain hop. Sprint still starts and stops through PlayerCommand.

Windows that are clients of a server never run them. game/server_mods.rs: tick_server_mods at the end of the tick diffs the players (player_joined, player_left), delivers the tick's chat and block events in order, then calls tick. Block events come from players' breaking and placing (the acting player is the guest during as_guest); chat from the local chat path and the hub's new HostEvent::PlayerChat; a guest's /command reaches its mod before vanilla's dispatcher. tell and command replies go to their player (the window's chat or a SystemChat); broadcast goes to every player and the log. --dev-mod now works on the server thread, and servers check a dev mod's file once a second from their tick. Every hook returns at once when no server mod runs; without the mods feature they are empty stubs. Docs: docs/mods.md (where server mods run, when hooks run, not yet), docs/api/mods.md.

Reads cost no copy: for a mod call the game lends Mods the levels' chunk maps (moved out with mem::take and put back after), only while a running mod has world. Writes for a level that isn't ticking (another dimension, in-frame) wait for it, up to 65,536. Test scripts get blocks (setup) and expect.blocks; cargo horizon-mod check reports a trial run's block writes. Example beacons: /beacon builds a glowstone pillar beside the player, /ground reads the block underfoot and the biome. parse_state is now a free function so the mod path shares it.

A sign paste strips formatting first, matching TextFieldHelper.getClipboardContents. --- crates/horizon-client/src/clipboard.rs | 5 + crates/horizon-client/src/creative.rs | 55 ++- crates/horizon-client/src/game.rs | 66 ++- crates/horizon-client/src/game/books.rs | 497 ++++++++++++++------ crates/horizon-client/src/game/clipboard.rs | 37 +- crates/horizon-client/src/game/sign_edit.rs | 314 +++++++++---- crates/horizon-client/src/game/stations.rs | 117 +++-- crates/horizon-client/src/multiplayer.rs | 120 ++--- crates/horizon-client/src/title.rs | 19 +- crates/horizon-client/src/title/tests.rs | 47 ++ crates/horizon-client/src/ui.rs | 11 +- 11 files changed, 890 insertions(+), 398 deletions(-) diff --git a/crates/horizon-client/src/clipboard.rs b/crates/horizon-client/src/clipboard.rs index c21460cdb..76872091c 100644 --- a/crates/horizon-client/src/clipboard.rs +++ b/crates/horizon-client/src/clipboard.rs @@ -346,6 +346,11 @@ mod tests { assert_eq!(filter_text(s, true), "abc\nde\u{80}"); assert_eq!(strip_formatting("§aRed§r §zx§"), "Red §zx§"); assert_eq!(helper_clipboard_contents("§lone\r\ntwo"), "one\ntwo"); + // TextFieldHelper.getClipboardContents runs before insertText's filter. + assert_eq!( + filter_text(&helper_clipboard_contents("§aHello"), false), + "Hello" + ); } struct Field { diff --git a/crates/horizon-client/src/creative.rs b/crates/horizon-client/src/creative.rs index 249e40b11..033b4daec 100644 --- a/crates/horizon-client/src/creative.rs +++ b/crates/horizon-client/src/creative.rs @@ -1,7 +1,7 @@ //!

Each run walked `mining` and the `destroying` map, and formatted `block/destroy_stage_` for every crack it found before looking that string up in the atlas. The list is computed once, at the top of the function, and the passes read it. The ten stage names are a const table, so a crack costs one lookup and no allocation. Nothing between the two passes touches `mining` or `destroying`, which are only read there, so the list the second pass used to rebuild was always identical to the first one. No behaviour change: the same ten sprite names, and a stage above 9 still finds no sprite and skips the crack.

Now: - BlockEntity::Campfire keeps four slots with their cookingProgress and cookingTime, saved as Items, CookingTimes and CookingTotalTimes; both campfires share the minecraft:campfire block entity type. It is not a Container (only Clearable), so hoppers don't reach in. - CampfireBlock.useItemOn: a campfire_cooking input goes into the first free slot (placeFood) with its recipe's time; the use is consumed whether or not there was room, the item is used up outside creative, interact_with_campfire is awarded and a block_change goes out. A client of a server leaves it to the server. - cookTick (lit): each item's progress rises; a finished item's result drops at the block (Containers.dropItemStack), the slot empties and a block_change goes out. cooldownTick (unlit): progress falls by 2. - Breaking the campfire drops its items (preRemoveSideEffects). - The update tag (Items) reaches a server's clients, and CampfireRenderer draws the items on the fire.

The hub's `HostEvent::Chat` went through `system_message`, which asks for `receive_system_messages` — true at Commands Only — so the line passed. `Game::player_message` shows a chat line as `ChatSource::Player`, which is the permission `ChatListener` checks for player chat; `lan_log_event` routes `HostEvent::Chat` there. `/say` and `/me` arrive as chat messages too (say_command, emote_command), so they follow the same permission as they do for the guests' own packets; command feedback such as `/list` is a system message and keeps the system-message permission. Reproduced on the pre-fix build: host at Commands Only, guest sends `baseline-visible` → the host shows ` baseline-visible`. With this change the same line stays hidden at Commands Only and shows at Shown.

Only the chunk-generation path, which uses `horizon_world::loot`, enchanted anything — which is why #1911 and #1437 looked fixed. The dispatcher now runs both, as vanilla does: `EnchantWithLevelsFunction` picks from `EnchantmentHelper.enchantItem`'s results (a book becomes one enchanted book), `EnchantRandomlyFunction` picks one compatible enchantment at a level between its min and max, and both resolve `options` as a tag, a list or one id, else the whole registry. `Items` carries that registry now (`Items::enchantments`), and `StationData` shares the same copy instead of loading a second one. Verified in game: six `/loot give … end_city_treasure` rolls gave 10 pieces of gear, all 10 enchanted (unbreaking 3, mending 1 + protection 4, …), where all 10 were bare before.

The crystals had their own remote constructor; the dragon had none. The client now keeps the server's dragon in Game::dragon: handleAddEntity builds it (full health, hovering, as its constructor does), SetEntityData applies DATA_HEALTH_ID and DATA_PHASE, SetEntityMotion its velocity, and its moves interpolate like other living entities. tick_remote_dragon is the client side of EnderDragon.aiStep: wing flaps and their sound, the growl, checkCrystals' nearest-crystal search for the healing beam, the flight history and the parts; a dead dragon rises and bursts as in tickDeath. Hurt animations flash it, removal and level changes drop it, and the player's attacks pick its parts and send the server their ids. The in-frame fight is unchanged; its nearest-crystal search moved into nearest_crystal_to, shared with the client. Fixes #1530.

Horizon keeps both on `Game` (`inv_clicks`, `inv_drag`, `last_inv_click`), and nothing cleared them when a screen closed: a press whose release never reached the screen — the pointer left the window, or the screen closed between the press and the release — left a quick-craft drag running, and `Clicks::press` answers `None` for every later press, so clicks went dead on every screen after it. `Game::reset_inventory_clicks` now runs when a container closes and when the pointer is grabbed again (the inventory's screens are behind us), which is the lifetime vanilla gives that state.

The game draws it under the stack's own tooltip (`Game::draw_stack_tooltip`), which the inventory, creative, container, beacon and trading hovers now use. Verified in game: a bundle with 64 stone shows one slot and a full red bar labelled "Full!"; one with 32 stone and 8 dirt shows two slots (32 stone first, as the next out) over a half-filled blue bar; an empty one shows the description and "Empty". --- crates/horizon-client/src/bundle.rs | 203 +++++++++++++++++++++ crates/horizon-client/src/game.rs | 3 +- crates/horizon-client/src/game/beacon.rs | 3 +- crates/horizon-client/src/game/stations.rs | 177 +++++++++++++++++- crates/horizon-client/src/game/trading.rs | 3 +- 5 files changed, 373 insertions(+), 16 deletions(-) diff --git a/crates/horizon-client/src/bundle.rs b/crates/horizon-client/src/bundle.rs index 8658b5815..42473729f 100644 --- a/crates/horizon-client/src/bundle.rs +++ b/crates/horizon-client/src/bundle.rs @@ -166,6 +166,38 @@ impl Contents { Some(stack) } + /// The stacks inside, in display order (the first is the next out). + pub fn items(&self) -> &[ItemStack] { + &self.items + } + + /// `getNumberOfItemsToShow`: a full grid shows 11 and a `+N`, so the last + /// row keeps its fourth cell for the count. + pub fn shown_count(&self) -> usize { + let count = self.items.len();

It is Settings' Proxy row (`proxy` in settings.json), or `horizon-launcher settings proxy http://host:port`; without one, HTTPS_PROXY, HTTP_PROXY and ALL_PROXY apply, with NO_PROXY naming the hosts to reach directly. A local address never goes through it, and the Servers page's calls to a game server's API stay direct: they are on loopback and asked every second. horizon-port-pack builds its own agents, so the launcher hands it the address (net.rs); run on its own, it reads the same variables.

Vanilla and Paper trust those heightmaps, so a Horizon-made Nether reads its surface at y=192, above the bedrock roof, and the End 64 blocks too high. Re-saving a vanilla Nether chunk rewrote its yPos too. LevelShape (skylight, min_y, height per dimension folder) replaces the save path's sky_light flag. yPos, the saved sections, the PostProcessing lists and the heightmaps follow it, as SerializableChunkData.write does. LAN clients in the Nether and End now get the chunk's heightmaps; the heightmap check failed there and they were sent empty.

StructureStart::save and Piece::save write the tag vanilla writes. This covers the pieces of jigsaw pools (villages, pillager outposts, ancient cities, trail ruins, trial chambers, abandoned camps, bastions) with their pool element, junctions and liquid settings. Junctions keep delta_y and dest_proj, pool elements their processors as written. LegacyPiece::save defaults to None; a start with such a piece is not saved, as before. test_structure_start_nbt_parity compares the tags with the pinned server's own for one site of every jigsaw structure kind.

Vanilla rebuilds a missing section on load, but until a chunk is loaded nothing knows its beds, job sites, bells, nests, portals or lodestones. Saving a chunk now writes its POI records the way PoiManager saves its sections: each section with POI blocks, valid, one record per block of PoiTypes with its max tickets, free_tickets left out at 0. A chunk that lost its last POI and had a record gets an empty one, since vanilla trusts a valid section. The records are built on the region writer thread, which reads the saved record there, so unloading chunks reads no files on the tick thread.

Vanilla's `ItemStack.getHoverName()` checks `custom_name` first, then falls back to `getItemName()`, which retrieves `DataComponents.ITEM_NAME`. Previously, Horizon did not model `item_name` in `StackData`, causing items with custom base names from servers or resource packs to fall back to their default translation keys instead of the server-provided name. This adds `item_name` to `StackData`, decodes and encodes it across network item sync, and prioritizes it in `name_line` and hover tooltips. Fixes #2039.

The arm here drew unconditionally, so choosing Mending (or any one-level enchantment) shifted every roll after it. `horizon_world::loot`'s copy and `merchant.rs`'s already guard this; only the loot dispatcher in `items.rs` did not. Vanilla with `LegacyRandom(11)`: a Mending book followed by `set_count` uniform 1..64 is 46; the extra draw made it 28. `a_single_level_enchantment_draws_no_level` pins that (and the stored Mending level).

The mesher marks emitting faces with EMISSIVE_LAYER (bit 14 of the layer); the frame's alpha carries the mark to the HDR pass, which lifts only pixels that still show the world before the hand and HUD. horizon-hdr sends HDR metadata through VK_EXT_hdr_metadata, which wgpu doesn't: without it KWin clips scRGB content above 1.0 (80 nits).

The colour's alpha byte was always 0xFF: its low four bits now hold 15 minus the light level the face emits (EMISSION_BITS), so 0xFF still means none and the other four bits stay free. terrain.wgsl takes only the colour's rgb and passes the level on; Java shader packs get alpha 1; the section mesh fixture restores vanilla's 0xFF. The HDR pass still lifts any emitting face the same way; the level is there for scaling the lift by it later.

The mesher marks emitting blocks' faces (`EMISSIVE_LAYER`), the frame's alpha carries the mark, and only pixels that still show the world before the hand and HUD are lifted. On Vulkan, `horizon-hdr` sends HDR metadata (MaxCLL, mastering luminance), which wgpu doesn't: without it a compositor may clip everything above SDR white. KWin maps the content's reference white onto the desktop's SDR brightness, so on Linux the default Paper White matches SDR mode. `HORIZON_HDR_DEBUG=1` paints lifted pixels magenta. Not lifted yet: glowing particles, distant LOD terrain. +**HDR** (Display, off by default) presents to an scRGB swapchain (`Rgba16Float`, extended linear sRGB) on displays and compositors that offer it.

The behaviour exports (gameplay-facts.json is 55 MB) parse from bytes in memory instead of through a reader. ThinkPad (2 cores), 3 alternated runs: 0.63 -> 0.45 s with the behaviour snapshot cached, 2.40 -> 2.07 s on a first start.

an Order menu also sorts by rating or name (?sort= too). - A project's page shows the same, then a rating control: five stars when signed in (the account's own rating lit), "Sign in with GitHub to rate" (coming back to the page) when not, a note for its owners. - Ratings come from the registry service's GET /api/mods/ratings; a rating is POSTed with the session's CSRF token. Until the service answers, the pages show downloads only.

BenchmarksHorizon against Java Edition 26.3

-

Same machine, same world, same flight.

-

We run Horizon and vanilla Minecraft: Java Edition 26.3 one after the other on the same computer: a fresh world from the same seed, the same settings, and the same four flights over a village, a forest, the ocean and a mountain. Every figure comes from the same code for both games. Where Java does better, the tables say so.

- -
-

Measured by us

-

The project's own machines, at render distance 12 (vanilla's default) and 32. VSync off, no frame cap, a 1280x720 window, simulation distance 12, everything else at vanilla's defaults. Each figure is the median over the runs; the frame figures are averaged over the four flights.

Your hardware

-

Pick a graphics card, a processor and, if you know it, your memory. If we or at least three players have measured that pair, you see what was measured; otherwise an estimate from the nearest measured machine, as a range.

Render distance - - -

The picker needs JavaScript; the tables above and the method below work without it.

-

From players

-

Players who allow benchmark uploads in the launcher's data collection settings share the report of horizon-client --benchmark standard. Results are grouped by graphics card, processor and render distance, and a group shows only once at least 3 different installs are in it, so no one can be picked out. Only medians are published, with how the group's installs split by memory, graphics memory, drive and system in coarse classes (each class only with at least 3 installs too): no install ID, date, driver, exact memory or screen.

How the estimates work

-
-

An estimate starts from the measured machine closest to the one you picked, then scales its figures with a small table of specifications we wrote ourselves (no benchmark database):

-
    -
  • GPU factor: the geometric mean of the two graphics cards' ratio of FP32 shader throughput (TFLOPS) and of memory bandwidth (GB/s), as their makers state them.
    • -
  • CPU factor: the ratio of the two processors' single-thread scores: top boost clock times a rough factor per chip generation (Zen 4 = 1).
    • -
  • Frame rate: when the measured run split each frame into CPU and GPU time, the slower side is scaled by its factor; otherwise by the geometric mean of both. Whatever the split, the real figure lies between the measured one scaled by the smaller and by the larger factor; we widen that by 15% for the roughness of the table, and show it as the range.
    • -
  • Load times are CPU work (generating, lighting and meshing chunks), scaled by the CPU factor. Memory is not scaled: it follows the world and the settings, not the speed.
    • -
  • Memory size: when players' results say how much memory and graphics memory their machines have, a measured group whose players have neither yours counts as further away, and the estimate says what they had. With your memory picked, it also says when the game's peak use is a large share of it.
    • -
-

Estimates ignore drivers, the graphics API, thermal limits and the operating system, which can matter as much as the chip. Treat them as a rough idea, and run horizon-client --benchmark standard on your own machine for the real figure.

How we measure

-
-

tools/perf_bench.py starts each game from a fresh world (seed 1234, creative), waits until every chunk around the spawn is loaded and drawn, then for each scene teleports, waits for the chunks, holds for 2 seconds and flies a straight 192-block path in 12 seconds. Every frame is recorded. Vanilla runs as players get it (your own client, the official launcher's Java options, Java 25), driven by a small development-only mod that only calls the game's own code; nothing of Minecraft is shipped. The full method and its caveats are in docs/benchmark.md, and every raw report is in the repository.

-

Measure your own computer with horizon-client --benchmark standard --render-distance 12: it writes a report to the benchmarks folder of the game folder.

    Where Horizon is going

    -

    What is being done, what comes next, what shipped and where you can help. No dates: things are Now, Next or Later. Read it in plain words, or switch to the technical picture.

    The roadmap lives in the repository: ROADMAP.md, generated from roadmap/roadmap.toml. Pull requests carry the roadmap:<id> label of their item.

    -
    - -
    -
    -

    Every open issue and pull request, placed by its state on GitHub, as on Kira's work board in Discord.

    - -
    -

    - -

    Every release with what it changed, grouped by roadmap item in Technical, and a summary of each week. Also as journal.json.

    Good first tasks

    -

    Each one is a small difference from vanilla, with an issue that says how to see it.

    -

    Each links its issue; the technical text says where in the code and in vanilla to start.

    Ways to help

    -
    -
    -

    Tell us what differs

    -

    Something that doesn't play like vanilla is a bug. Say what you did, what happened and what vanilla does, with your Horizon version and system.

    -

    Report a bugSuggest something

    -
    -
    -

    Take a task

    -

    Pick a good first task or an open issue. On Discord, /claim 1234 tells everyone you are on issue 1234, so nobody starts the same work; /unclaim frees it.

    -

    Open issues

    -
    -
    -

    Bring your AI agent

    -

    On Discord, /agent connect gives your coding agent a personal token for Kira's MCP server: it reads the work board, claims tasks and posts its progress in your name.

    -

    Join the Discord

    -
    -
    -

    Benchmark your computer

    -

    Run the built-in benchmark and share the report: every new machine makes the performance work more accurate. No coding needed.

    -

    How to

    -
    -
    -
    -
    -

    Report a bug

    -

    One bug per report: something that breaks, or doesn't play like vanilla. It becomes an issue on GitHub, public, and you get its link to follow it. Search the open bugs first.

    - -

    Report it on GitHub or in #horizon-bugs on Discord, where Kira turns your post into an issue.

    -
    -
    -

    Suggest something

    -

    An idea for Horizon, or about something on the roadmap. The maintainers read every one, and the good ones become roadmap items. Nothing you send here is published.

    - -

    Post it in #horizon-ideas on Discord, or send it to Kira with /suggest.

    -
    -
    -

    The rules

    -
      -
    1. Vanilla is the specification. Wherever Minecraft 26.3 has the feature, Horizon does exactly what it does: read vanilla's code, then match it.
      2. -
    2. Small pull requests, proven. One change each, under about 500 lines, with the block python3 tools/pr_ready.py prints: formatting, Clippy, tests and the harnesses your change can affect.
      3. -
    3. Say who wrote it. If an AI agent wrote or posts it, the pull request says so, and commits keep its co-author line.
      4. -
    4. Never commit Mojang's files. No game jars, assets, decompiled code or prepared resources, and nothing taken from other mods' code.
      5. -

    Minecraft: Java Edition 26.3Rust

    -

    Horizon: The game you know, rebuilt in Rust.

    -

    The Minecraft: Java Edition 26.3 client and its game logic, rewritten in Rust and checked against the vanilla game by {{HARNESSES}} differential harnesses.

    -
    - Download the launcher - View on GitHub -

    01What it is

    -

    Horizon rebuilds Minecraft: Java Edition 26.3 in Rust, one subsystem at a time, and holds every piece to the same inputs as the vanilla game until the outputs are identical.

    -
    -
    - -

    Your own copy

    -

    Install Java Edition with the official launcher and play 26.3 once. Horizon builds its resources from those files on your machine, and never downloads or shares game files.

    -
    -
    - -

    Native on three platforms

    -

    Linux, macOS on Apple Silicon and Windows. Worlds come from a Rust port of the vanilla generators, drawn with vanilla's block models, lighting, sky and fog.

    -
    -
    - -

    Open source

    -

    Horizon's code is MIT. It contains no Minecraft code, assets or data; those belong to Mojang and Microsoft under the Minecraft EULA.

    Captured in the Rust client itself, with vanilla assets from the player's own copy and no mods or shaders.

    04The launcher

    -

    One small app, then play

    -

    The launcher installs Horizon, prepares it from your copy of the game and keeps both up to date.

    -
      -

    • One-click install

      Pick a release and it installs the build for your platform into its own folder, then prepares the resources from your Java Edition 26.3 install.

      • -

    • Updates on its own

      It looks for a new Horizon release when it starts and every four hours, and updates itself from the launcher's own releases.

      • -

    • Client or server

      Start the client, or host a server from the Servers page: create it, start it, watch players and the console, change its settings and keep backups.

      • -

    • Logs and crash reports

      The Settings page shows where the game's logs and crash reports are, and horizon-launcher logs prints them.

      • -

    • Modpacks and packs

      The Modpacks page reads a Modrinth or CurseForge pack and carries over the mods Horizon can run. The Mods page installs resource packs and modpacks from Modrinth.

    Privacy: this site sets no cookies, has no analytics or trackers and loads nothing from third parties except GitHub. To show the latest releases, patch notes, links and contributors, your browser asks api.github.com and raw.githubusercontent.com for them, and avatars.githubusercontent.com for the contributors' pictures; GitHub's privacy statement covers those requests. The launcher sends nothing unless you allow it: what it can send, and how to delete it.

    PrivacyData collection

    -

    Nothing leaves without your yes.

    -

    The Horizon launcher can send a few things that help make the game faster and steadier. It asks first, each kind has its own switch, and every switch is off until you turn it on.

    -
    -

    What can be sent

    -

    Only the kinds you allow, from the launcher's first-run question or Settings → Data collection:

    -
      -
    • Performance statistics, after each play session of a minute or more. These are the frame-time and tick-time percentiles and a 14-bucket histogram (never a recording of each frame), the peak memory, how long the game took to start and to load the world, and the settings that change performance (render and simulation distance, frame limit, VSync, fullscreen, graphics mode).
      • -
    • Crash reports, when the game crashes. They hold the error, where it happened in Horizon's code, your graphics adapter and settings. They hold no log, no world, no server and no resource packs.
      • -
    • Bug reports that you write and send yourself. The end of the game's log goes with one only if you add it after reading it, and lines of chat are removed first.
      • -
    • Benchmark uploads of the benchmarks you run. They are shown publicly on the Benchmarks page, only as medians of groups of at least 3 different installs with the same graphics card, processor and render distance; never one by one, and never with your install ID, the day, your OS version, driver, exact memory or screen.
      • -
    -

    Each one also carries the Horizon version, the day it was made (not the time), and a description of your machine, because that is what explains how fast the game runs on it:

    -
      -
    • the operating system, its version and the processor architecture;
      • -
    • the processor model, its cores and threads, and its base and boost clock where the system gives them;
      • -
    • the memory, rounded to the gigabyte;
      • -
    • the graphics card the game draws with: its model, maker, whether it is built into the processor or separate, its own memory, its driver version and the graphics interface (Vulkan, Metal, DirectX 12);
      • -
    • the kind of drive the game folder is on (NVMe, SSD or hard disk);
      • -
    • the screen the game opened on: its size in pixels, refresh rate and scaling;
      • -
    • whether the computer is a laptop or a desktop, and whether it runs on battery.
      • -
    -

    No serial number, computer name, user name, network address or file path is read. Each item also carries a random install ID. The launcher makes that ID the first time you allow something; it says nothing about you and exists only so that your data can be deleted.

    -

    Never sent: your Microsoft or Minecraft account name or UUID, world names, server or LAN addresses, chat, and your user name or home folder in file paths. Before anything is kept, those are replaced with placeholders, along with e-mail and IP addresses. The server does not store the IP address requests come from.

    -

    The launcher shows exactly what would be sent: Settings → Data collection → View what would be sent, or horizon-launcher data show. Every field is listed in docs/telemetry.md.

    - -

    The "I'm playing" ping

    -

    The game sends an anonymous "I'm playing" ping, so the launcher can show how many people play Horizon right now. It is sent once a minute while you play, whatever the switches say.

    -

    It holds: a random number made when the game starts and forgotten when it closes, the Horizon version, your operating system (Linux, macOS or Windows), and whether you have a world open to LAN or to friends. It does not hold: your account, your install ID, world or server names, your hardware or settings, or anything you do in the game. The random number changes every time you start the game, so two of your sessions can't be linked to each other or to you.

    -

    The server keeps the pings in memory only, never on disk, and not with the address they came from (that is used only to stop abuse, as below). A session counts while it pinged in the last two minutes and is then forgotten. What it shows is the number playing now, per version and with a world open, rounded.

    - -

    Why

    -

    To find what is slow or crashes on which machines, and fix it. The ping shows players, and Horizon, how many people play right now. Benchmark uploads also show other players how Horizon runs on hardware like theirs. Nothing is sold, shared for advertising, or used to identify you.

    - -

    On what basis

    -

    For the switches: your consent (Article 6(1)(a) of the EU's General Data Protection Regulation). It is given kind by kind, recorded on your computer with the version of the question you answered and when, and withdrawn at any time with the same switches. Withdrawing deletes what was waiting to be sent. When what is collected changes, the launcher asks again, and nothing new is sent until you answer. The ping holds nothing that identifies you; the address it comes from is used only to limit how often one address may send, kept in memory for an hour at most and never stored.

    - -

    Where and how long

    -

    Items wait on your computer (telemetry/ in the game folder) and are sent compressed when the launcher starts or closes, to Horizon's own server, telemetry.playhorizon.dev, hosted by Railway in the European Union (Amsterdam, the Netherlands). The server keeps them for 180 days, then deletes them. What stays after that are anonymous totals per day, Horizon version, operating system, GPU maker and render distance (for example "120 sessions on macOS with Apple GPUs at render distance 12"). They hold no install ID, and groups too small to be anonymous are never shown. Published results also show how players split by memory size (in steps: 8, 16, 32 GB…), graphics memory, drive type, operating system and built-in or separate graphics, each class only once it holds at least 3 different installs; the exact values, the driver, the clocks and the screen are never published.

    - -

    Deleting your data

    -

    Settings → Data collection → Delete my data, or horizon-launcher data delete. The server deletes everything sent under your install ID, your share of the totals is recomputed, anything waiting on your computer is removed, and you get a new install ID. You can also turn everything off, or delete the telemetry/ folder.

    - -

    Your rights and contact

    -

    Horizon is made by Ludovic Marie, who is responsible for this data. To ask for a copy of what was sent under your install ID, have it corrected or deleted, or ask anything about it, write through lu4ovic.com (give your install ID, shown in Settings → Data collection). You can also complain to the data protection authority where you live.

    What's new in Horizon

    -

    Each release lists what it adds and fixes, then its full notes and its downloads. New versions come out many times a day as changes land, and the launcher installs each one once it has passed its test. The launcher has its own releases.
