mojs-player

Player controls for mojs. Intended to help you to craft mojs animation sequences. To be clear, this player is not needed to play mojs animations. It is just a debug tool that gives you the ability to:

• control your sequences with GUI while working on them
• it saves the current progress of your animation thus you don't loose the focus
• it gives you bounds to constrain focus point of your animation
• it gives you the control over the speed of animation
• it gives you the ability to seek animations freely
• it saves player's state and settings thus they not get lost when page reloaded

Installation

The MojsPlayer depends on mojs >= 0.225.2 so make sure you link it first.

CDN:

<script src="//cdn.jsdelivr.net/mojs-player/latest/mojs-player.min.js"></script>

NPM:

[sudo] npm install mojs-player

Bower:

bower install mojs-player

Import MojsPlayer constructor to your code (depends on your environment) :

const MojsPlayer = require('mojs-player').default;
// or
import MojsPlayer from 'mojs-player';

If you installed it with script link — you should have MojsPlayer global.

Usage

Construct MojsPlayer and pass your main Tween/Timeline as the add option:

// const mainTimeline = new mojs.Timeline({});
// .. some code regarding timeline ..
const mojsPlayer = new MojsPlayer({ add: mainTimeline });

The add option is the only required option to launch. Player's controls should appear at the bottom of the page.

You can also set other player initial state:

// ..
const mojsPlayer = new MojsPlayer({
  // required
  add:      mainTimeline,
  // optionally
  className:    '',         // class name to add to main HTMLElement
  isSaveState:  true,       // determines if should preserve state on page reload
  isPlaying:    false,      // playback state
  progress:     0,          // initial progress
  isRepeat:     false,      // determines if it should repeat after completion
  isBounds:     false,      // determines if it should have bounds
  leftBound:    0,          // left bound position  [0...1]
  rightBound:   1,          // right bound position [0...1]
  isSpeed:      false,      // determines if speed control should be open
  speed:        1,          // `speed` value
  isHidden:     false,      // determines if the player should be hidden
  precision:    0.1,        // step size for player handle - for instance, after page reload - player should restore timeline progress - the whole timeline will be updated incrementally with the `precision` step size until the progress will be met.
  name:         'mojs-player', // name for the player - mainly used for localstorage identifier, use to distinguish between multiple local players
  onToggleHide(isHidden) {  // should be called after user taps on the hide-button (isHidden is a boolean, indicating the visibility state of the player)
    if (isHidden) {
      // do something when player is invisible
    } else {
      // do something when player is visible
    }
  }
});
