Closes the editing loop on the NPC service catalog: dump a .wbkd
to JSON, hand-edit serviceKind / requiresGold / factionRequiredId
/ gossipTextId (e.g. retag a city-mail NPC from Mailbox kind to
GuildBanker, raise stable master cost from 1s to 5s, gate an
auctioneer behind faction rep), re-import to a byte-identical
binary.
The exporter emits both serviceKind (int 0..11) and the human-
readable serviceKindName ("banker" / "mailbox" / "auctioneer" /
"stable-master" / "flight-master" / "trainer" / "innkeeper" /
"battlemaster" / "guild-banker" / "reagent-vendor" /
"tabard-vendor" / "misc"); the importer accepts either form.
Verified byte-identical round-trip on all three presets
(city / battle / prof). CLI flag count 1030 -> 1032.
Open replacement for AzerothCore's npc_vendor / npc_trainer /
npc_gossip / npc_options SQL tables plus the engine's hard-coded
service-type dispatch. Defines the kinds of services NPCs can
offer (Banker / Mailbox / Auctioneer / StableMaster /
FlightMaster / Trainer / Innkeeper / Battlemaster / GuildBanker
/ ReagentVendor / TabardVendor / Misc) and the per-service
metadata (gold cost, faction gating, gossip text id).
When a player right-clicks an NPC, the engine looks at the
NPC's serviceId list (from WCRT.npcFlags or equivalent) and
dispatches to the appropriate service-frame handler — Banker
opens the inventory expansion frame, Auctioneer opens the
auction house, StableMaster opens the pet stable. This catalog
defines what each service actually does and what preconditions
it requires.
Cross-references back to WCRT (creature.npcFlags decodes into a
list of service ids defined here), WFAC (factionRequiredId
references factionId for rep-gated services like Argent
Tournament), and WGSP (gossipTextId references menuId for the
"How can I help you?" dialogue line).
Three preset emitters: --gen-bkd (5 city services typical of a
capital city), --gen-bkd-battle (3 battlemaster services for
each Vanilla BG queue), --gen-bkd-profession (4 profession
services). findByKind(kind) is the engine helper used by NPC
spawning to find e.g. all FlightMaster services configured for
a server.
Validation enforces id+name presence, serviceKind 0..11, no
duplicate ids; warns on:
- Mailbox kind with non-zero gossipTextId (mailboxes are
gameobject services with no NPC dialogue; gossip won't show)
- Innkeeper kind with gossipTextId=0 (no welcome/bind dialog;
will silently bind the hearthstone)
- Battlemaster kind with non-zero requiresGold (battle queue
services are typically free)
Wired through the cross-format table; WBKD appears automatically
in all 16 cross-format utilities. Format count 86 -> 87; CLI
flag count 1025 -> 1030.
