Modernize the Fabric module from Minecraft 1.20.1 (Yarn mappings) to
Minecraft 26.2 (Mojang mappings, Java 25), and add several server-admin
commands.
Toolchain:
- minecraft 26.2, Fabric Loader 0.19.3, Fabric API 0.153.0+26.2
- Loom 1.17-SNAPSHOT, Gradle 9.5.1, Java 25
- 26.2 ships de-obfuscated: no mappings declaration, plain `implementation`
deps, no refmap/legacy mixin AP
- Gradle 9 `base { archivesName }`; trimmed settings.gradle to Fabric-only
(dead Common/Forge modules removed)
Source migration (Yarn -> Mojang names) across all commands, events,
mixins and PlayerDataManager, including the reworked APIs: Identifier,
sendSystemMessage, level(), teleportTo, flattened inventory, GameRules
get/set, the clock/weather subsystems (time/weather delegate to vanilla),
and the new NameAndId/ban-list profile resolution. Mixin @Inject targets
updated to mojmap method names (verified at runtime on a 26.2 dev server).
New commands:
- /kick, /kill, /ban, /ban-ip, /banlist, /broadcast (+/bc), /tpall
- /msg now also gates /tell and /w
- /warp with no args lists warps
Commands that collide with vanilla (/kick /kill /ban /ban-ip /banlist /msg
/tell /w) remove the vanilla node before registering so the fleettools.*
permission gates actually apply (Brigadier otherwise drops the mod's
requires() when merging onto the existing node).

Teleports to saved locations now restore the saved facing instead of keeping the player's current view: - /home, /warp, /spawn and /back store yaw+pitch with each location and apply them on teleport - setLastLocation now captures from the player directly (simplifying all call sites) with an explicit overload for setting a specific location Back-on-death: after a player respawns, their death location is recorded as their /back point (BackOnDeathHandler via ServerPlayerEvents.AFTER_RESPAWN, reading the dead entity's position so the respawn teleport can't clobber it). On by default; deny `fleettools.back.ondeath` to opt a player/group out. Locations saved before this version have no facing and default to yaw 0.

Back-on-death: capture the death location at the moment of death (ServerLivingEntityEvents.AFTER_DEATH) instead of reading the old player's position during respawn, which returned the respawn point and lost the death dimension (e.g. dying in the nether sent /back to the overworld). The captured spot is promoted to the /back point in AFTER_RESPAWN. Respawn abilities: re-apply stored fly and god-mode state on AFTER_RESPAWN. The respawned entity starts with default abilities, so previously a player had to toggle /fly off and on again after dying. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…1.6.3) Teleport requests (EssentialsX-style, available to all players by default): - /tpa <player>, /tphere <player>, /tpaccept [player], /tpdeny [player] - Full multi-request queue: each recipient can hold one pending request per requester; a new request from the same player replaces their old one and becomes the most recent. /tpaccept and /tpdeny with no argument act on the most recent non-expired request, or on a named requester when given. Requests expire after 2 minutes. /coords: split self vs others. /coords (no arg) shows your own coordinates and is available to everyone (fleettools.coords); /coords <player> requires fleettools.coords.others (operators). Keep inventory: now gated by the fleettools.keepinventory permission, granted to operators by default, with a per-player /keepinv override that takes precedence so servers without a permissions manager can still grant/revoke it in-game.

…1.7.0) Teleport / homes: - Multiple named homes: /home [name], /sethome [name], /delhome [name], /homes; default limit 3 (fleettools.homes.unlimited bypasses). - /tptoggle to block incoming teleport requests. Communication: - /reply (/r) replies to the last whisper partner. - Timed mutes: /mute <player> [time] [reason] (auto-expiring). AFK: - /afk plus auto-AFK after 5 min idle, cleared on movement. - AFK players are excluded from the sleep-percentage check (SleepStatusMixin). - AFK shows as a grayed name with an [AFK] tag in the player list. Chat formatting (EssentialsXChat-style, opt-out when StyledChat/StyledPlayerList present): LuckPerms prefix/suffix on chat and the player list, keeping messages cryptographically signed by only decorating the ChatType.Bound name (PlayerListMixin) rather than re-sending. AFK status also flows through %luckperms:prefix% (transient prefix node) and a %fleettools:afk% placeholder. Soft integrations (compile-only, isModLoaded-guarded): Text Placeholder API, LuckPerms, StyledChat, StyledPlayerList. Abilities: per-tick reconciliation re-applies stored fly/god after gamemode changes and respawns, preserving active flight across the change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Vanish (/vanish, /v): - Hide the player's entity (TrackedEntityMixin), tab list (PlayerInfoSendMixin filters outgoing player-info packets so relogs and StyledPlayerList can't re-add the entry), and locator bar (WaypointVanishMixin + waypoint rebuild on toggle). - Suppress presence broadcasts: AFK, sleep count, join/quit, advancements, deaths, /list, server-ping count/sample, and command name-completions. - Vanish persists across relogs (in-memory) for silent quit/rejoin. - Mobs ignore vanished (and AFK-protected) players via MobTargetMixin. - Permissions: fleettools.vanish[.others/.see]. Also: AFK-protection feature (AfkProtectCommand + getAfkProtection), /list override, and README updates. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
When a player vanishes, broadcast a "left the game" message; when they un-vanish, broadcast "joined the game" - so vanishing looks like a normal logout/login to players who can't see them (staff who can are skipped to avoid contradictory lines). Mirrors vanilla's placeNewPlayer/removePlayerFromWorld wording, color, and the "(formerly known as X)" renamed-join variant (driven by the same name cache comparison), so the messages are indistinguishable from real ones - including Bedrock players via Geyser/Floodgate whose cached name differs.

Incoming /tpa and /tphere requests now include clickable [Accept] and [Deny] buttons in chat that act on that specific requester - handy when several requests arrive at once. The buttons use a custom click event (fleettools:tpaccept / tpdeny with the requester in an NBT payload) rather than run_command, so the client doesn't show the "run this command?" confirmation prompt. A mixin on the packet listener handles the action on the server thread and shares the same accept/deny logic as the typed commands. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What & why
Modernizes the Fabric module from Minecraft 1.20.1 (Yarn) to Minecraft 26.2 (Mojang mappings, Java 25) and adds a set of server-admin commands. The mod compiles cleanly and was verified loading on a 26.2 dev server (all mixins apply, 0 errors).

/kick /kill /ban /ban-ip /banlist /msg /tell /w) remove the vanilla node before registering, because Brigadier merges a same-named registration onto the existing vanilla node and drops the mod'srequires()predicate — so thefleettools.*permission gates would otherwise never apply. Removal uses a small reflection helper inFleettoolsMod(Brigadier exposes no public remove).fleettools.kick,fleettools.kill(+.others),fleettools.ban,fleettools.banip,fleettools.banlist,fleettools.broadcast,fleettools.tpall. As with all fabric-permissions-api nodes, they surface in LuckPerms after first use or can be set manually./ban-ipresolves an online player's IP viagetIpAddress(), so the player-name form requires them to be online; raw IPs work regardless.🤖 Generated with Claude Code
