Aframe-keyboard-controls NPM

A-Frame `keyboard-controls` Component

Keyboard controls for A-Frame.

Overview

Bindings and events for keyboard controls on an A-Frame VR scene. When combined with ProxyControls.js (with the proxy-controls component for A-Frame), can also receive remote keyboard input by WebRTC.

Usage

Movement + keyboard events:

<a-scene>
  <a-entity camera
            keyboard-controls>
  </a-entity>
</a-scene>

Keyboard events only (no movement):

<a-scene>
  <a-entity camera
            keyboard-controls="enabled: false">
  </a-entity>
</a-scene>

The full list of options can be seen in keyboard-controls.js.

Usage + Remote Device

ProxyControls.js ⇢ Docs

Example:

<a-scene proxy-controls>
  <a-entity camera
            keyboard-controls>
  </a-entity>
</a-scene>

Check Keyboard State

To check the pressed/unpressed state of a given Keyboard.code, use the isPressed() method:

var keyboardControls = el.components['keyboard-controls'];
keyboardControls.isPressed('ArrowLeft');

Events

keyboard-controls comes with a polyfill guaranteeing support for KeyboardEvent.key and KeyboardEvent.code. When a keydown or keyup event is detected, an extra event is created with the code attached. Example usage:

<a-entity keyboard-controls
          sound="src: reload.wav;
                 on: keydown:KeyR">
</a-entity>

A complete list of code values may be found here.

Known Issues

In OS X, pressing the Command/Meta (⌘) key blocks all other key events. For example, pressing A, pressing ⌘, releasing A, and then releasing ⌘ would create a keydown:KeyA event, but no keyup:KeyA. Because of this, I do not recommend using the Command/Meta key in your apps.
