fixed-timestep

renew engine: an AI-first game engine in Rust, built to be operated. Bit-deterministic fixed-timestep simulation in Q47.16 fixed point, Vulkan rendering through ash, and every capability driven from the CLI with schema-versioned JSON. 29 modular crates, desktop and mobile. Apache-2.0. Early development.

Gondwana Game Engine

Header-only fixed timestep runner for deterministic updates. std::chrono API, time scaling, clamps. ☕ C++20+.

Small, deterministic, single-threaded ECS

Experimental Rust foundations for deterministic simulations, including fixed-step timing and render interpolation; component libraries only, not yet a complete engine or runnable host.

Deterministic fixed timestep physics simulation decoupled from variable display refresh rates using state accumulator and alpha render interpolation in TypeScript.

Arena-Spiel in Echtzeit im Browser: ausweichen, schiessen, aufsteigen. Fester Zeitschritt und gesaeter Zufall — derselbe Lauf laesst sich Tick fuer Tick wiederholen und nachrechnen. Eine einzelne HTML-Datei.

⏱️ Run fixed-timestep simulations with ease using this lightweight, header-only library designed for C++ projects. Simple, efficient, and reusable.
