SteelScene

Animation devtools for production code

Features

• Animate existing sites from localhost using the devtools
• Build animations without thinking about specific frameworks

Why use SteelScene?

• Human readable code in HTML, JSON, and Fluent API
• Zero config

Power this project up with 🌟s, ^ star it please.

Getting Started

SteelScene has three important concepts. targets to animate, states to transition targets between, and scenes to control groups of targets.

Building Scenes

There are three different ways to build out animations with SteelScene. Demo Project on CodePen

HTML

SteelScene automatically will try to load scenes in the body when the document is ready.

 <s-scene name="boxes" duration="800" easing="Power1.easeOut">
    <s-target select="#box1">
        <s-state name="middle" x="0" easing="Power2.easeOut" />
        <s-state name="right" x="100px" />
    </s-target>
</s-scene>

JSON

You can load JSON, HTML, or provide a document selector to load after the document is loaded.

steel.load([
   {
      name: 'boxes',
      duration: 800,
      easing: 'Power1.easeOut',
      targets: [
         {
            select: '#box1',
            states: {
               middle: { x: 0,  easing: 'Power2.easeOut' },
               right: { x: '100px' }
            }
         }
      ]
   }
])

Fluent API

SteelScene also has a fluent API that is pretty simple.

const box1 = steel
	.target('#box1')
	.on('middle', { x: 0, easing: 'Power2.easeOut' })
	.on('right', { x: '100px' })

const boxesScene = steel
	.scene('boxes', { duration: 800, easing: 'Power1.easeOut' })
	.add(box1)

Changing states

Transitioning a scene

A single transition

const boxScene = steel.scene('boxes')
boxScene.transition('right')

Multiple transitions in sequence

const boxScene = steel.scene('boxes')
boxScene.transition(['right', 'middle'])

Transitioning a target

Transitioning a known state

const box1 = steel.target('#box1')
box1.transition('right')

Multiple transitions in sequence

const box1 = steel.target('#box1')
box1.transition(['right', 'middle'])

Setting a target/scene

Immediately setting the state of all targets in a scene

const boxesScene = steel.scene('boxes')
boxesScene.set('right')

Immediately setting the state of a single target

const box1 = steel.target('#box1')
box1.set('right')

Setup

Setup for use in the browser

Include this script

<script src="https://unpkg.com/steel-scene/dist/steel-scene.min.js"></script>

Setup for bundling (or if you want typings for TypeScript)

npm install steel-scene --save

Plugins

Instead of reinventing web aniamtion, SteelScene works seamlessly with your existing animation library

• GSAP (GreenSock)

Other notes

• Transitions must have a duration (at this point)
• State properties override target properties, target properties override scene properties
• SteelScene will not work without using a Plugin

Get a simple prototype working and posted. Stay tuned!
