Deterministic fixed timestep simulation updates with state interpolation

time traveling in-memory datastore

Timestep AI - Durable agent execution framework with cross-language state persistence and multi-model support for OpenAI Agents

Zero-dependency RAF scheduler with game-pausable timers, fixed-timestep physics, profiler hooks, and tab-switch guard.

Authoritative realtime rooms on serverless: a leased fixed-timestep tick loop, a WebSocket relay, and Redis pub/sub as the bus.

Fixed-Timestep Ticker (with container interpolation) PixiJS plugin

A fixed timestep for the browser

Arobust game loop implementation with fixed timestep updates and variable rendering

Host-blind fixed-timestep cell engine. One App owns the rules and the grid; the host only paints, feeds keys, and stores bytes.

Fixed-timestep, deterministic game loop manager that supports arbitrary time-scaling.

Rapier physics for @sigx/three — <Physics>, <RigidBody>, <Collider>, collision events and a debug renderer on a fixed-timestep loop

Fixed‑timestep update loop with independent draw rate and quantized interpolation

A fixed timestep game loop with variable fps

Engine-agnostic fixed-timestep coordinator for deterministic game logic: accumulator, catch-up limits, dropped-tick accounting, interpolation alpha, pause, reset, and manual stepping.

Headless rigid-body physics: fixed-timestep integration, GJK/EPA collisions, and impulse solving for the Vanilla Slice engine.

The shared Demystify Play engine — fixed-timestep loop, input intents, DOM/canvas surfaces, packaged audio, the zero-network trap and the shared game mini-kit.

micro js engine with fixed timestep and keyboard events

A JavaScript game engine for the Game Closure SDK, built on Canvas and DOM rendering backends. Runtime implementations are optimized at a low level to develop high-performance games.

Generate word clouds in JavaScript.
