NGIN alpha

AI-first / Three.js game engine

NGIN

Describe the game.
The modules already walk.

Alpha Three.js WebGPU engine. Walking, cars, boats, and physics are built. In active development. Prompt the rest.

From folder to playable.

Open NGIN in your AI editor. Build your game in its own folder. The engine and sandbox stay unchanged.

  1. Run locally

    Open a terminal in the NGIN folder and start a PHP server.

    php -S localhost:8080
    localhost:8080/game.php

  2. Give your AI the context

    Start with the NGIN prompt and agent rules. Describe your game and name the one folder the AI may edit.

    Open the AI prompt Download SKILL.md

  3. Build a separate game

    Copy games/template/ into your own game folder. Launch its page and verify the engine and demo are unchanged.

Modules the AI is supposed to reuse

A material library to build on.

16×16 procedural wood, stone, brick, and grass. Generated at runtime, no texture packs.

You write the prompt. NGIN keeps the defaults.

Use NGIN. Build only in games/my-game/. Keep the engine and sandbox unchanged. A person walks on grass, drives a truck, and takes a boat across a pool. Do not invent walking, cars, or water from scratch.

How to build a traversal level

Use NGIN walking. Third person, drag to look. Build a courtyard with stairs, a ramp, and a trampoline. Add matching colliders to every solid surface. Keep the block character and default movement.

Walking module
How to add a delivery loop

Use NGIN driving, carry, and inventory. Add a truck and orange crates. E enters the truck, F carries, G stows. Add a marked delivery area and count crates delivered. Do not rewrite vehicles or carry.

Carry module
How to add water and atmosphere

Use NGIN water, boats, and day/night. A pool with a fishing boat, start at dusk, and enable rain. Keep buoyancy and the existing sky system. Add my game logic separately.
