API reference

Callable behavior is grouped by domain under nexBash.api. A small set of lifecycle helpers and accessors also live directly on the global.

api.diagnostics	Read-only troubleshooting snapshots	report

api.control

The manual lifecycle verbs. start and stop each flip the master enabled switch, toggle the in-game "Bashing" reflex group, and drive the bash actor — there is intentionally no separate enable/disable. Package and routine automation must use api.hunt; api.control does not provide ownership, correlation, or scoped cancellation.

nexBash.api.control.start();        // resolve the area for this location, go live
nexBash.api.control.stop();         // go inert; report the run summary
nexBash.api.control.enableLokiCheck(); // arm a one-shot Loki affliction probe

start() is a visible no-op with a notice when no area matches your location. stop() is silent when no run was active.

api.hunt

hunt is the sole versioned automation boundary for a package that needs nexBash to perform PvE while retaining ownership of its own workflow. The caller supplies the objective, route, target names, and correlation identity; nexBash owns the temporary area lease, combat, safe route verification, progress, cancellation, and restoration of the player's normal area.

const result = nexBash.api.hunt.start({
  owner: {
    package: "task-runner",
    routineId: "task-runner:daily-clear",
    invocationId: crypto.randomUUID(),
  },
  targets: ["a cave rat"],
  route: [12001, 12002, 12003],
  startRoom: 12001,
  slow: true,
  objective: { type: "killQuota", requiredKills: 5 },
  onEvent(event) {
    console.log(event.runId, event.type, event.progress);
  },
});

if (result.ok) {
  // Cancellation is correlated: a stale or foreign run id cannot stop it.
  nexBash.api.hunt.stop({ runId: result.runId, reason: "callerCancelled" });
}

The supported objectives are:

• { type: "routeClear" }: complete one normal route pass, and succeed only when every unique route room was actually reported clear.
• { type: "killQuota", requiredKills }: count exact objective-target deaths and repeat complete route passes after the respawn interval until the quota.

The optional slow boolean selects slow-mode for this session and defaults to false; the prior setting is restored when the session finishes. The optional respawnIntervalMs is 10000 by default and accepts 100 through 60000. The optional area may be a complete Area instance. Without it, the API resolves a registered area for the current location. Configured NPC metadata is preserved whenever available. A requested target missing from that area gets the standard new Npc() defaults on the session's transient clone. If the location has no registered area, nexBash builds a transient area from the current GMCP identity, requested targets, and route. These inferred definitions are never registered or persisted.

start() returns either { ok: true, runId, unsubscribe, snapshot } or a structured rejection. Only one normal run or hunt session may own nexBash at a time. get(runId) returns a frozen active or recently completed snapshot. subscribe(runId, fn) attaches an additional run-scoped listener and returns an unsubscribe function. The callback and nexbash4.hunt.* topics carry the same correlated event shapes.

Feature detection is explicit:

nexBash.capabilities.huntSession;          // "1.1.0"
nexBash.api.hunt.version;                  // "1.1.0"
nexBash.api.hunt.capabilities.objectives;  // ["killQuota", "routeClear"]
nexBash.api.hunt.capabilities.slowMode;    // true
nexBash.api.hunt.capabilities.transientNpcDefaults; // true

api.config

// Make a ready-made Area instance the live bashing area (runs its lifecycle).
nexBash.api.config.setArea(areaInstance);

// Add a complete Area definition to the runtime catalog without activating it.
nexBash.api.config.registerArea(areaInstance, { replace: false });

// Register the current GMCP area as a new (empty) area definition and persist it.
nexBash.api.config.addArea();

// Add an NPC target to the active area. Persisted when the area is registered.
nexBash.api.config.addNpc("a Nelbennir alchemist");

setArea is the programmatic entry point for driving nexBash through an Area built by a caller; ephemeral areas passed this way are not added to nexBash.areas. It returns true when the Area crossed the ownership boundary and false for invalid input or a re-entrant transition. The replacement emits nexbash4.area.deactivated, .activated, and one final .changed event with reason: "api"; integrations should subscribe to those events instead of adding callbacks to the Area instance.

registerArea accepts a complete Area, clones it into the runtime catalog, and returns { ok, added, area }. Identity is the canonical game area id/name. An existing definition is retained unless { replace: true } is explicit. This is the generic extension point for private catalogs and independently shipped area providers; registration does not activate the area or start combat.

api.observe

The ingress vocabulary mirroring nexSys4's api.observe.*: triggers, skill matches, and GMCP bridges report what they observed with got / lost, and the owner models decide what changed. Scoped by subject so the two are never conflated — npc.* is a combatant's attributes, self.* is your character's nexBash-owned state.

// A combatant gained / lost a shield (name optional → the active target).
nexBash.api.observe.npc.shield.got("a tuar warrior");
nexBash.api.observe.npc.shield.lost();

// A crowd-control type landed on / faded from a combatant.
nexBash.api.observe.npc.cc.got("sensitivity");
nexBash.api.observe.npc.cc.lost("sensitivity");

// A nexBash-tracked effect changed. got/lost flip availability (bloodcloak, maya);
// charge accrues a deathcape charge (0–50) and flips availability on the first one.
nexBash.api.observe.self.effects.got("bloodcloak");
nexBash.api.observe.self.effects.lost("maya");
nexBash.api.observe.self.effects.charge("deathcape");

// Battlerage availability: the shared balance, or a named ability's own cooldown.
nexBash.api.observe.self.battlerage.got();
nexBash.api.observe.self.battlerage.lost();
nexBash.api.observe.self.battlerage.ability.got("disintegrate");
nexBash.api.observe.self.battlerage.ability.lost("disintegrate");

api.strategy.profiles

Named customization variants of the active class's strategy. See Profiles.

nexBash.api.strategy.profiles.list();        // ["default", "solo", "group"]
nexBash.api.strategy.profiles.active;         // "default" (getter)
nexBash.api.strategy.profiles.apply("group"); // swap to a profile (persists)
nexBash.api.strategy.profiles.save("solo");   // snapshot current tuning as a profile
nexBash.api.strategy.profiles.remove("solo"); // delete a profile (default is protected)

Each command resolves against the active strategy: an unsupported class or an unknown profile surfaces an in-client notice and is a no-op — it never throws.

api.diagnostics

const report = nexBash.api.diagnostics.report();

report() prints one JSON block to the developer console and returns the same structured object. It correlates the run machine, room/area matching, target priorities, exact attacker projections and budgets, strategy/profile lanes, action gates, offence blockers, integrations, and persisted-settings schema. It does not modify live state. Character and player names are omitted; NPC names and item/target IDs are included because they are needed to diagnose exact-name and targeting failures.

Top-level lifecycle helpers

Member	Purpose
nexBash.setStrategy(name)	Look up a class strategy by name and make it active; surfaces a notice and resets to inert on an unsupported class. Returns whether one was activated.
nexBash.aliases(input)	Parse and execute an nb … command string (the alias entry point). See Commands.
nexBash.notice(text)	Emit a nexBash status notice to the client (respects the notices option).
nexBash.log(text)	Emit a diagnostic log line (respects the logging option).

Catalog and trace handles

Handle	Purpose
nexBash.actionCatalog	The flat, namespaced action catalog: entries, keys, byId, ambiguousIds, get(key), has(key), list({namespace}), listById(id).
nexBash.trace	The decision trace stream: enable(), disable(), subscribe(fn), list(), clear(), isTracing(). Off by default.
nexBash.classes	The Npc and Area constructors, for building areas programmatically.
nexBash.areas	The registered area definitions (sorted by name).
nexBash.strategies	The shipped per-class strategies, keyed by class id.

Return values

Predicate and toggle methods return booleans. Configuration mutations commonly return whether a change was made (and emit a notice). Callers should not assume a mutation is synchronous server confirmation — use state and events to observe the confirmed result.

Events are separate

Listeners do not live under api. Other packages attach listeners through the Nexus eventStream global. The events page lists the topics nexBash emits and the host topics it reacts to.
