Features

Mailboxes

Mailboxes provide delayed player and server deliveries containing a written letter and optional items. Offline notifications are delivered on join, and a player-specific hologram indicates waiting mail. Runtime text, dialog labels, messages, and delivery timing are configurable under mailboxes.

Features are discovered from dev.stemcraft.feature and loaded through BaseFeature.

World and Travel

Feature	Purpose
HubFeature	Defines the hub world, join routing, and /hub command behavior
TeleportUtils	Registers warps, spawn, world teleport, /back, /top, /jump, and related travel commands
RandomFirstSpawn	Applies per-world random first spawn rules and persistence
Coordinates	Action bar and boss bar coordinate displays through /coord and /coordbar
NamedRegions	Permanently names discovered biome territories and structures, with coordinate-bar and optional Pl3xMap presentation; see Named Regions
GameModeAliases	Registers short aliases such as gms, gmc, gma, and gmsp
GameModeInventories	Keeps inventory state separate across gamemode profiles

Content and UI

Feature	Purpose
CustomBooks	Configurable books plus /book command surfaces
QuestFeature	Private NPC quests, updating owner-bound books, objective progress, prerequisites, and rewards
InteractiveMenus	Book/form-based interactive menu system with admin editing
CustomCommands	Config-defined command aliases with player/server sender control
PlayerTabList	Header/footer tab list rendering and update loop
PlayerGameMessages	Join, quit, death, and related configurable player messages

PlayerTabList treats its header, footer, and name_format as MiniMessage. Both gray and grey tag spellings are accepted. {world} uses the shared player-facing world name, while {world-raw} exposes the underlying world folder name. By default, underscores become words and multi-part map names treat their first word as a category: bedwars_amazon becomes Bedwars: Amazon, while dimension suffixes remain natural, such as survival_nether becoming Survival Nether and bedwars_forest_nether becoming Bedwars: Forest Nether. Override any generated name for Player Tab and Coordinates with:

worlds:
  world:
    display-name: "World"

Feature Design Rules

Common feature characteristics:

• config-driven enablement
• self-registration of listeners and commands
• preference for existing services instead of direct Bukkit utility code
• focused ownership over one gameplay concern

If a new capability is optional and domain-specific, it usually belongs in dev.stemcraft.feature.

Notice boards provide graphical lobby boards containing player-authored headers, short messages, and author names. Posts expire automatically and are displayed through the reusable image-map service.

Newer guide, rendering and progression features

Feature	Runtime contract
StemBotFeature	Owner-only Citizens guide and action interpreter; see STEMBot
ProfessionsFeature	Eight level-1-to-100 skills with world/mode filtering; see Professions
FormattedSigns	Supported ampersand codes and glyphs, explicit stemcraft.sign.format grant

See Permissions for individual player/admin grants. There is no required stemcraft.player bundle. Custom commands enforce a permission only when one is configured; fixed /survival and /creative shortcuts run their teleport as the server.
