English documentation

Simpludify is an experimental code-first TypeScript 2D engine. It provides a DOM-free simulation Core and a Web host for Pixi rendering, browser input, asynchronous scene preparation, and DOM UI. There is no published npm SDK yet; clone the source workspace to start.

Language coverage

The primary site currently provides Japanese onboarding, concepts, practical guides and sample instructions. This English section directly renders the existing detailed API, architecture, roadmap, performance and licensing documents from the repository. It is not a complete translation of every Japanese page.

Quick start

git clone https://github.com/oz-coden/Simpludify.git
cd Simpludify
npm ci
npm run dev -- --example character

Use Node.js 22.12+; CI uses Node 24. Open the printed localhost URL, focus the game area and use WASD. WebGL is the primary verified rendering path. The pinned Pixi can select a fallback; a no-WebGL Character Canvas2D startup is covered, not full fallback compatibility. Chromium is the automated browser target. The sample gallery launches each game in a separate iframe; Signal Run, Blockfall and Prism Raid also support touch controls. Blockfall demonstrates integer-grid puzzle rules, seeded bags, hold, ghost pieces and headless replay without Collider physics. Character and Beacon Field require a keyboard for movement.

Scope

Trigger/Solid contacts and bounded inverse-mass position correction are implemented. This is not a force/impulse rigid-body engine or continuous collision detection. Audio, sprite animation, networking and Windows packaging are not implemented. API semantics may change before stabilization.

Prism Raid uses the new upward Triangle shape with independent circle Triggers. See the shooter API review and measurements for reproduction commands, supported rendering paths and measured limits.
