newLane(id: string, foe: string) → void

state — the live match One record per lane, keyed "ember" / "ash". `owner` is the peer id of the player commanding that lane, or nil when the AI commander runs it.

reset( ) → void

Reset the match back to its opening position. Any slice may call it; the entrypoint calls it when the scene enters play.

on(event: string, fn: (any) → void

The events the slices agree on. Emitting an event not on this list is allowed; documenting it here is how the next slice discovers it. matchStarted {} waveTick { wave, spawned = { {lane, creep} } } creepSpawned { lane, creep, entity } -- lane = the lane it marches down creepKilled { lane, creep, bounty, by } -- `by` = "ember" | "ash" creepLeaked { lane, creep, leak } livesChanged { lane, lives, delta } goldChanged { lane, gold, delta } incomeChanged { lane, income } sendQueued { lane, creep, cost } heroDamaged { lane, health, max, amount } heroDied { lane } heroRespawned { lane } abilityUsed { lane, ability } matchOver { winner }

off(event: string, fn: (any) → void

emit(event: string, payload: any) → void

creep(id: string) → void

helpers — the shared arithmetic, so five slices agree on one answer

lane(id: string) → void

foe(id: string) → string

gateOf(laneId: string) → void

Where a lane's creeps enter, and what they march toward.

nexusOf(laneId: string) → void

marchDir(laneId: string) → number

March direction along X for a lane's creeps: +1 for ember, -1 for ash.

progress(laneId: string, x: number) → number

Progress 0..1 of a world x along a lane's march (0 = gate, 1 = nexus).

clampToLane(laneId: string, x: number, z: number) → void

Keep a world position inside its lane's playable band.

spend(laneId: string, amount: number) → boolean

Spend gold. Returns false and changes nothing if the lane can't afford it.

grant(laneId: string, amount: number) → void

leak(laneId: string, amount: number) → void

A creep reached a nexus. Drains lives and ends the match at zero.

send(laneId: string, creepId: string) → boolean

Buy one creep into the foe's lane. The single entry point for sending — the economy slice calls it, the HUD calls it, the AI commander calls it.
