noa-examples

Several small example worlds built on the noa voxel engine. The easiest way to get started with noa is to clone this repo and hack on these demos.

Live demos:

• hello-world - a bare minimum world, suitable for building on top of
• testbed - a testbed world that minimally implements most/all engine features
• stress test - a demo made to test the performance of long view distances and crunchy terrain

Usage

To build and serve the examples locally:

# (clone this repo)
cd noa-examples
npm install
npm test      # serves demos on localhost:8080
npm start     # serves demos in prod mode

Then open localhost:8080 to view the three demos.

There's also a build script to generate all bundles into the docs directories, using vite. If you prefer webpack, the hello-world demo has a sample webpack config.

Those using React may want to check @MCArth/noa-cra-example, which is a ported noa example built with create-react-app.

Dependency / build notes

Babylon dependency:

Noa uses Babylon.js for 3D rendering, but references it as a peer dependency (so that game worlds can specify their Babylon version/modules). This means game worlds should declare a dependency on @babylonjs/core or similar, rather than loading in a prebuilt babylon script.

noa dependency:

This engine is under active development. The current release is available from npm as noa-engine, but if you want the latest changes may want to change your package.json to point to the #develop branch on github:

  "dependencies": {
    "noa-engine": "github:fenomas/noa#develop",
  },

Or, if you want to hack on both the engine and a game world together, it's easiest to clone the noa repo alongside to this one, and then edit package.json to reference your local copy of the engine:

  "dependencies": {
    "noa-engine": "file:../noa",
  },

Note that after changing package.json you'll need to run npm i.
