popmotion-aframe-role

A-Frame plugin for Popmotion

Popmotion Actor role to enable A-Frame animation, physics and input tracking.

Examples

• Physics
• Some rather obnoxious-yet-demonstrative animation](http://codepen.io/popmotion/pen/GoZpjo?editors=101)

Use

<a-cube width="3" color="red"></a-cube>

import ui from 'popmotion';
import aframeRole from 'popmotion-aframe-role';
 
const cube = new ui.Actor({
    element: document.querySelector('a-cube'),
    as: aframeRole
});

cube is now a standard Popmotion Actor, except with an applied A-Frame Role.

This allows you to run a standard Tween, Simulate or Track action:

const moveBackAndForth = new ui.Tween({
    values: {
        x: 5
    },
    duration: 600,
    ease: 'easeInOut',
    yoyo: true
});
 
cube.start(moveBackAndForth);

Create many A-Frame Actors

As A-Frame elements are DOM elements, you can use ui.select to create multiple Actors at once. For instance:

ui.select('a-cube', {
    as: aframeRole
});

Will return an Iterator of Actor elements (see full documentation). You must remember to set as on Actor initialisation.

Supported properties

All numerical properties can be set with Popmotion.

• position properties can be set with x, y, and z.
• scale and rotation properties can be set eg scaleX and rotateY.
• Dash-case characters are set as camelCase, eg radius-bottom becomes radiusBottom.

Advanced: create an A-Frame Actor

If you're creating a lot of A-Frame Actors and don't want to set as each time, you could make something like this:

import { Actor } from 'popmotion';
import aframeRole from 'popmotion-aframe-role';
 
class AFrameActor extends Actor {
    constructor(props, ...args) {
        props.as = aframeRole;
        super(props, ...args);
    }
}
 
const cube = new AFrameActor(document.querySelector('a-cube'));
