Work in progress. These docs describe Spawnite at launch, and some parts are still being built.

AuthoritativeStep

A step on a world that decides outcomes: a room’s, or a game played alone. A system with no runsOn receives one, and if (step.authoritative) narrows a SystemStep to it. It is the Authority every outcome function takes first, dealDamage(step, target, damage), and a call that only the room may make, such as a knockback through pushCharacter from a system that is not a predicted system, takes it too.

Property Modifier Type Description
[authorityBrand] readonly true -
[entityAuthorityBrand] readonly true -
authoritative readonly true True: this world decides outcomes, as isAuthoritative says.
deltaSeconds public number The step’s length, which every caller passes as fixedStepSeconds.
input? public StepInput What the characters under the client’s authority read. Left out where the caller steers none, as a room’s server does: each character keeps what she was last sent.
moverRecords? public readonly MoverRecords[] Where the movers keep this step’s calls: one list an entity, the one whose entity names it, holding a record for each of its first four mover calls. A re-run call takes its record in place of sweeping where nothing the call reads has changed, and a page keeps one list for each entity of her set on each step it may re-run. Left out, the movers keep none.
pushes? public boolean On a re-run, whether a character pushes a dynamic body she walks into, as the world’s own step does: a client’s replay, which does not rewind the body, leaves it.
rerunEntities? public readonly Entity[] The entities a re-run steps: her page’s predicted set, as the room’s last word names it, re-run together after a correction. Only the predicted systems run on such a step, each once a tick over every entity of the set and nothing else, and input is left out: each steps on the InputTrait it holds. Left out on the world’s step.
tick readonly number The room’s tick the step is for: on a room, its own step; on her page, the tick her page leads the room on, a replayed step the tick it first ran on; in a game with no room, its own step, from 0.
world readonly World The world the step runs on: what a hook that receives a step, such as onPlayerJoin(step, player), reads its world from.
