feat: moderation feature skeleton (/core admin + mod mode + tools)
New feature fr.luc.crcore.features.moderation, opt-in via
CRCoreConfig.setupModeration() (also enabled by setupAll()).
Core abstractions:
- ModerationState: full player snapshot (inv + armor + offhand, XP,
health, food, location, gamemode, allowFlight/flying, walk/fly speed).
Immutable, restoreTo(player) restores everything.
- ModerationService interface + ModerationServiceImpl (with
protected onAfterEnter/onAfterExit hooks) +
BukkitEventFiringModerationServiceImpl (fires ModerationEnterEvent /
ModerationExitEvent).
- ModerationRepository interface + InMemoryModerationRepository
(skeleton — SQLite impl with BukkitObjectOutputStream serialization
planned).
- ModeratorTool interface: getKey/getSlot(0..8)/buildIcon +
onLeftClick/onRightClick/onInteractEntity. ModeratorToolRegistry
preserves registration order, slot collision = replace.
- Exceptions: ModerationException base + AlreadyActive + NotActive.
- Events: ModerationEvent base + Enter + Exit.
5 skeleton tools in the hotbar:
- slot 0: TeleportRandomPlayerTool (compass, right-click → tp random)
- slot 1: InventorySpyTool (chest, right-click on player → open inv)
- slot 2: FreezeTool (ice, right-click on player → toggle freeze)
- slot 7: VanishToggleTool (ender eye, click → toggle vanish)
- slot 8: ExitTool (barrier, click → exit mod mode)
Slots 3-6 free for custom tools.
ModerationListener routes interactions and locks hotbar:
- PlayerInteractEvent → tool.onLeftClick / onRightClick (with cancel).
- PlayerInteractEntityEvent → tool.onInteractEntity (with cancel).
- PlayerDropItemEvent / PlayerSwapHandItemsEvent: cancel for mods.
- InventoryClickEvent: cancel only when top inv is the mod's own inv
(preserves InventorySpyTool's ability to manipulate target's inv).
- PlayerJoinEvent: re-applies vanish for already-vanished mods.
- PlayerQuitEvent: cleanup freeze state.
- PlayerMoveEvent: cancel block-position changes for frozen players,
keeping head rotation free.
Mod mode lifecycle:
- enter: snapshot + clear inv + populate hotbar + CREATIVE +
allowFlight + vanish + ModerationEnterEvent.
- exit: state.restoreTo(player) + unvanish + unfreeze + repo delete +
ModerationExitEvent.
/core admin (perm crcore.admin, player-only): toggle on/off.
Messages moderation.enter.success / moderation.exit.success added
to crcore-messages.yml.
CRCoreConfig.setupModeration() + isModerationEnabled() flag.
CRCore: buildModerationService() and registerDefaultModeratorTools()
override points, moderation() / getModerationService() getters with
IllegalStateException guard. Builds + registers ModerationListener at
enable() when feature on. CoreCommand extended to take ModerationService;
registers AdminToggleSubCommand only when service non-null.
Skeleton limitations documented in features.md:
- In-memory repo only (server crash = lost inv) — SQLite planned.
- InventorySpyTool opens real inv (no read-only wrapping yet).
- TeleportRandomPlayerTool is a placeholder for a future player-picker
GUI.
- No moderation.*.broadcast keys yet.
- No /core admin <player> (self-toggle only).
Docs: section 11 in features.md, decision logged in decisions.md
(skeleton scope + rationale), setup.md snippet updated,
new moderation-class-diagram.puml, README.md updated.
