noa-examples

Two small example worlds built on the noa voxel engine.

Live demos:

• hello-world - a bare minimum world, suitable for building on top of
• test - a testbed world that minimally implements most engine features

Usage

To build and serve the examples locally:

(clone this repo)
cd noa-examples
npm install
npm start     # runs /src/hello-world
npm test      # runs /src/test

The start and test scripts serve each world via webpack-dev-server, so you should be able to find them at localhost:8080 or thereabouts.

There's also a build script to generate bundles into the docs directories.

Dependency / build notes

Babylon dependency:

Noa uses Babylon.js as its 3D engine, 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:

The noa engine is under active development, so this module declares its dependency directly on the source repo's develop branch (github:andyhall/noa#develop), so as to pull in the latest bleeding-edge build. If you want to hack on something stable you may want to change the dependency to noa-engine (to get the current stable build from npm), or a specific noa version/commit/etc.

When hacking on the engine:

If you want to hack on both the engine and a game world side-by-side, the easiest way is to clone the noa repo next to this one, and change this module's dependency to point at "file:../noa" or whatever. However there is some weirdness with how webpack resolves peer dependencies on the local file system.

The fix for this is to include symlinks: false in your webpack config. This is already done in this repo, but if you start from scratch and get build errors, that's the reason.
