es6-tween

ES6 implementation of tween.js

let coords = { x: 0, y: 0 };
let tween = new TWEEN.Tween(coords)
    .to({ x: 100, y: 100 }, 1000)
    .on('update', object => {
        console.log(object.x, object.y);
    })
    .start();

requestAnimationFrame(animate);

function animate(time) {
    requestAnimationFrame(animate);
    TWEEN.update(time);
}

Installation

Download the library and include it in your code:

<script src="js/Tween.js"></script>

CDN-Hosted version

Using unpkg hosted version

You can also reference a unpkg-hosted version in your code, thanks to unpkg. For example:

<script src="https://unpkg.com/es6-tween/dist/Tween.min.js"></script>

Using jsdelivr hosted version

You can also reference a @jsdelivr-hosted version in your code, thanks to jsdelivr. For example:

<script src="https://cdn.jsdelivr.net/es6-tween/latest/Tween.min.js"></script>

Using cdnjs (TO-DO)

Sorry for that, but cdnjs doesn't accept none of my app, so if someone can from cdnjs contributors, would be nice.

More advanced users might want to...

Use import

import * as TWEEN from './node_modules/es6-tween/src/Tween';

Use yarn

yarn add es6-tween

Use npm or bower

npm install es6-tween

or

bower install es6-tween

Then include the Tween.js module with the standard node.js require:

let TWEEN = require('es6-tween');

And you can use Tween.js as in all other examples--for example:

let t = new TWEEN.Tween( /* etc */ );
t.start();

You can run script commands to build modules into single UMD compatible file:

Use Webpack + Babel Transpiler

npm run build

Then reference the library source:

<script src="dist/Tween.min.js"></script>

Tests

You need to install npm first--this comes with node.js, so install that one first. Then, cd to es6-tween's directory and run:

npm install

if running the tests for the first time, to install additional dependencies for running tests, and then run

npm test

every time you want to run the tests.

If you want to add any feature or change existing features, you must run the tests to make sure you didn't break anything else. If you send a PR to add something new and it doesn't have tests, or the tests don't pass, the PR won't be accepted. See contributing for more information.
