From 43f2497f1fef1a19b046da6c5c247af48e55621e Mon Sep 17 00:00:00 2001 From: Shreyas Date: Wed, 28 Oct 2026 17:13:45 +0530 Subject: [PATCH 001/110] Sulfur cubes: synchronize size metadata and adult egg spawns Include sulfur cubes in AbstractCubeMob size metadata serialization and remote data handling so adult cubes retain their size across the network. Adult sulfur cubes spawned from spawn eggs now correctly render and act as adults rather than defaulting to size 1 babies. Vanilla reference: AbstractCubeMob.ID_SIZE, SulfurCube.setSpawnSize.

Those that used the column for every dimension read the world's (World::bottom_y, top_y), which is -64..320 in all three vanilla levels; those that chose per dimension read the level's shape (LevelAccess from world.shape, Dim's bounds from Dim::shape). Each level's World now holds its shape where it is made. chunk::every_section replaces the per-file [true; SECTIONS] arrays of the fluid scans. Every value read is the one in use today.

A refused command line now exits 2 without a crash report; errors keep 1 and panics 101. The crash report's path stays the last stderr line, its prefix now a constant (crash::SAVED_LINE). docs/api/launch.md is the surface page; docs/api/launch-reference.md is generated from game/launch_api.rs and a test keeps the two together.

A column is lit from the blocks of its whole 3x3, so it holds light from a neighbour whose own light job has not landed yet. An edit in it then runs the incremental relight, which reads only lit columns: its darkening removes that neighbour's light and nothing can put it back, and the neighbour's job landing does not relight the column. The stale border stays, and is saved. Columns whose light an edit (or a replayed edit) changed beside a loaded, unlit column now get a full light job, as vanilla's light engine, with one light storage for every chunk, never loses it.

Two faults stacked up: - draw_frame answered CurrentSurfaceTexture::Validation with Err on every frame; the loading screen runs ControlFlow::Poll, so the warn ran ~16k times a second (130k log lines in the report) while nothing recovered. - SpriteAnimator::new asked the animated sprites pipeline for its bind group layout after the error scopes in pipeline() had been popped. A device lost during that window makes create_compute_pipeline return a silent invalid placeholder (device-lost errors bypass the scopes), so the scopes saw nothing, and the out-of-scope get_bind_group_layout then hit wgpu's uncaptured-error path and panicked. pipeline() now returns the layout queried while the scopes are open, where a validation error is caught and the CPU path takes over, as it already does for drivers without working compute shaders. Validation on acquire now gets the swapchain a fresh configuration like Outdated does, then reattaches the window like Lost does once that has not helped, and a frame is skipped (Ok(false)) instead of failed; the counter resets on the next acquired frame.

The client read the flag for other entities only and hid its own body, cape, first-person arm and name tag (and thinned its effect swirls) only for the effect, so the real body showed under the pose. Keep the own flag from SetEntityData (reset on login and on a respawn without KEEP_ENTITY_DATA) and use it with the effect wherever the own player's isInvisible is asked.

VanillaCreativeTabsExporter now builds the tabs with permissions and marks the stacks only that build lists (permissions_only). Creative keeps every exported stack and rebuilds its tabs and search tab for hasPermissions (canUseGameMasterBlocks and the option), as CreativeModeInventoryScreen does on opening and in containerTick (tryRefreshInvalidatedTabs): a selected operator tab left empty gives way to the default tab. The option is switchable again. test_creative_parity.py runs with and without permissions. Part of #3393.

Vanilla's ThrowableProjectile.applyInertia and AbstractHurtingProjectile.applyInertia read Entity.isInWater (wasTouchingWater), which the previous tick's Entity.baseTick -> updateFluidInteraction set from the deflated bounding box after the move (EntityFluidInteraction.update: some water surface at or above the box's bottom), and which is still false on the first tick. So a pearl thrown under water lost a fifth of its speed on the first tick (it lands about 6.0 blocks away instead of 7.4), one skimming just above a pool slowed as if under water, and one whose box dipped into the next column's water did not slow at all. The projectile now keeps touching_water from the box after each move (ProjWorld reads it through MobWorld::fluids, the mobs' port of the same test); llama spit, whose base tick runs before its move, tests its box at the start of the tick. Client-side arrows test their box too. Part of #3072.

Vanilla's client channel starts with ReadTimeoutHandler(30) (Connection$1.initChannel), so the client socket now gets a 30 s read timeout. A lost connection also showed Horizon's raw error text (on Windows the localized OS message). Connection.exceptionCaught's reasons replace it: disconnect.timeout ("Timed out") for the read timeout, disconnect.genericReason ("Internal Exception: ...") for any other failure, and disconnect.endOfStream when the server closed the stream (Connection.channelInactive). The integrated server's in-memory pipe keeps no timeout, as vanilla's local channel has none. Part of #3520 (Connection#exceptionCaught).

The hub's tracker had no such check, so a guest in spectator mode stayed paired with everyone: its AddEntity, equipment and nametag still reached the other players, and their crosshair still picked it. Player states now carry whether the player is a spectator, viewers too, and the pair check follows broadcastToPlayer. Going in or out of spectator mode checks the player's pairs again (vanilla's ChunkMap.move does it at the player's next move), so the others lose it, or get it back with its armour, at once.

The remote client had no case for these events, so on a server a breaking pickaxe, armour piece or wolf armour was silent and left no crumbs, for this player and for everyone else. Handle them: find the stack in the slot (the own inventory, or the mob's or other player's equipment), play its break_sound component at the entity's feet unless the entity is silent, and spawn the five item crumbs of spawnItemParticles. Entity.DATA_SILENT is now kept for remote entities so the silent check works.
