AnimPanel

A utility panel to make working with Greensock Animation Platform timeline animations easier.

---

Intro

AnimPanel simplifies the process of building complex timeline-based animations using the Greensock Animation Platform by adding a handful of extremely useful debugging tools, including:

• Play, Pause, and Restart buttons
• A visual playback scrubber
• Buttons to dynamically change the playback speed (1x, 0.5x, 0.2x, etc)
• A display of the current timeline time
• For TimelineMax timelines, automatically-added buttons to jump to each label in the timeline
• The ability to easily set custom loop in and out ranges for focusing on a specific span of the overall timeline, including making these in/out points persistent between page refreshes
• Keyboard shortcuts for common actions

Install

You can install AnimPanel via npm:

npm install anim-panel --save

or simply include it in your HTML:

<script src="anim_panel.js"></script>

Use

// Require the module if you're using something like browserify or webpack
var AnimPanel = require('anim-panel')
 
// Create your Greensock timeline using TimelineLite or TimelineMax
// (using TimelineMax gets you extra goodies like label buttons)
var tl = new TimelineMax({});
 
// Add some stuff to your timeline (see the gsap docs if you don't know how to do this)
tl.add(…);
 
// Create the AnimPanel, passing it your Timeline instance
new AnimPanel(tl);

  }
});
