Usage (Scripts)

In the dist/ folder, download any package(s) you need. Include the scripts on your page, and all components are automatically registered for you:

<script src="https://cdn.jsdelivr.net/gh/c-frame/aframe-extras@7.5.2/dist/aframe-extras.min.js"></script>

replace 7.5.2 by another tag or a commit hash (for example 3e0ab50) if you want to use a build from master branch. You can look at the commits and use the latest commit hash.

For partial builds, use a subpackage like aframe-extras.controls.min.js. Full list of packages above.

A-Frame Version Compatibility

A-Frame	Extras
v1.4.0	v7.0.0
v1.3.0	v7.0.0
v1.2.0	v7.0.0
v1.1.0	v6.1.1

NOTE: Several components and examples also rely on aframe-physics-system.

Usage (NPM)

npm install --save aframe-extras

// index.js
import 'aframe-extras';
// or specific packages
import "aframe-extras/controls/index.js";
import "aframe-extras/pathfinding/index.js";

Once installed, you'll need to compile your JavaScript using something like webpack with three defined as external, see webpack.config.js in this repo for an example.

Deprecated Components

The following components existed in previous versions of A-Frame Extras, but have been removed as of the latest release

Component	Removed in	Reasons
kinematic-body	7.0.0	Using physics for movement is unstable and performs poorly. When preventing players from passing through obstacles, use a navigation mesh instead whenever possible. The kinematic-body component constrainted player movement using physics, and depended on aframe-physics-system. Using physics for locomotion is not VR-friendly, and often glitchy even for traditional 3D experiences. Use a navigation mesh instead, whenever possible.
jump-ability	7.0.0	Dependent on kinematic-body
a-hexgrid	7.0.0	Was based on this repo, which is no longer maintained, and does not work with recent versions of THREE.js.
mesh-smooth	7.0.0	Intended for JSON models, but the JSON Loader is no longer part of this repo. More background here.
