28 ## A basic animatable element
30 Elements that can be animated should implement the `Polymer.NeonAnimatableBehavior` behavior, or `Polymer.NeonAnimationRunnerBehavior` if they're also responsible for running an animation.
36 Polymer.NeonAnimationRunnerBehavior
42 // provided by neon-animation/animations/scale-down-animation.html
43 name: 'scale-down-animation',
50 // this event is fired when the animation finishes
51 'neon-animation-finish': '_onNeonAnimationFinish'
54 // run scale-down-animation
57 _onNeonAnimationFinish: function() {
58 console.log('animation done!');

66 ## Animation configuration
68 <a name="configuration-types"></a>
71 An element might run different animations, for example it might do something different when it enters the view and when it exits from view. You can set the `animationConfig` property to a map from an animation type to configuration.
77 Polymer.NeonAnimationRunnerBehavior
87 // provided by neon-animation/animations/scale-up-animation.html
88 name: 'scale-up-animation',
92 // provided by neon-animation-animations/fade-out-animation.html
93 name: 'fade-out-animation',
101 'neon-animation-finish': '_onNeonAnimationFinish'
105 this.style.display = 'inline-block';
106 // run scale-up-animation
107 this.playAnimation('entry');
111 // run fade-out-animation
112 this.playAnimation('fade-out-animation');
114 _onNeonAnimationFinish: function() {
116 this.style.display = 'none';
122 [Live demo](http://morethanreal.github.io/neon-animation-demo/bower_components/neon-animation/demo/doc/types.html)
124 You can also use the convenience properties `entryAnimation` and `exitAnimation` to set `entry` and `exit` animations:
129 value: 'scale-up-animation'
132 value: 'fade-out-animation'
137 <a name="configuration-properties"></a>
138 ### Configuration properties
140 You can pass additional parameters to configure an animation in the animation configuration object.
141 All animations should accept the following properties:
143 * `name`: The name of an animation, ie. an element implementing `Polymer.NeonAnimationBehavior`.
144 * `node`: The target node to apply the animation to. Defaults to `this`.
145 * `timing`: Timing properties to use in this animation. They match the [Web Animations Animation Effect Timing interface](https://w3c.github.io/web-animations/#the-animationeffecttiming-interface). The
146 properties include the following:
147 * `duration`: The duration of the animation in milliseconds.
148 * `delay`: The delay before the start of the animation in milliseconds.
149 * `easing`: A timing function for the animation. Matches the CSS timing function values.
151 Animations may define additional configuration properties and they are listed in their documentation.
153 <a name="configuration-multiple"></a>
154 ### Using multiple animations
156 Set the animation configuration to an array to combine animations, like this:
162 // fade-in-animation is run with a 50ms delay from slide-down-animation
164 name: 'slide-down-animation',
167 name: 'fade-in-animation',
176 <a name="configuration-encapsulation"></a>
177 ### Running animations encapsulated in children nodes
179 You can include animations in the configuration that are encapsulated in a child element that implement `Polymer.NeonAnimatableBehavior` with the `animatable` property.
185 // run fade-in-animation on this, and the entry animation on this.$.myAnimatable
187 {name: 'fade-in-animation', node: this},
188 {animatable: this.$.myAnimatable, type: 'entry'}
195 <a name="page-transitions"></a>
198 *The artist formerly known as `<core-animated-pages>`*
200 The `neon-animated-pages` element manages a set of pages to switch between, and runs animations between the page transitions. It implements the `Polymer.IronSelectableBehavior` behavior. Each child node should implement `Polymer.NeonAnimatableBehavior` and define the `entry` and `exit` animations. During a page transition, the `entry` animation is run on the new page and the `exit` animation is run on the old page.
202 <a name="shared-element"></a>
203 ### Shared element animations
205 Shared element animations work on multiple nodes. For example, a "hero" animation is used during a page transition to make two elements from separate pages appear to animate as a single element. Shared element animation configurations have an `id` property that identify they belong in the same animation. Elements containing shared elements also have a `sharedElements` property defines a map from `id` to element, the element involved with the animation.
207 In the incoming page:
214 // the incoming page defines the 'entry' animation
216 name: 'hero-animation',
233 In the outgoing page:
240 // the outgoing page defines the 'exit' animation
242 name: 'hero-animation',
252 'hero': this.$.otherHero
259 <a name="declarative-page"></a>
260 ### Declarative page transitions
262 For convenience, if you define the `entry-animation` and `exit-animation` attributes on `<neon-animated-pages>`, those animations will apply for all page transitions.
267 <neon-animated-pages id="pages" class="flex" selected="[[selected]]" entry-animation="slide-from-right-animation" exit-animation="slide-left-animation">
268 <neon-animatable>1</neon-animatable>
269 <neon-animatable>2</neon-animatable>
270 <neon-animatable>3</neon-animatable>
271 <neon-animatable>4</neon-animatable>
272 <neon-animatable>5</neon-animatable>
273 </neon-animated-pages>
276 The new page will slide in from the right, and the old page slide away to the left.

279 ## Included animations
281 Single element animations:
283 * `fade-in-animation` Animates opacity from `0` to `1`.
284 * `fade-out-animation` Animates opacity from `1` to `0`.
285 * `scale-down-animation` Animates transform from `scale(1)` to `scale(0)`.
286 * `scale-up-animation` Animates transform from `scale(0)` to `scale(1)`.
287 * `slide-down-animation` Animates transform from `translateY(-100%)` to `none`.
288 * `slide-up-animation` Animates transform from `none` to `translateY(-100%)`.
289 * `slide-left-animation` Animates transform from `none` to `translateX(-100%)`;
290 * `slide-right-animation` Animates transform from `none` to `translateX(100%)`;
291 * `slide-from-left-animation` Animates transform from `translateX(-100%)` to `none`;
292 * `slide-from-right-animation` Animates transform from `translateX(100%)` to `none`;
294 * `transform-animation` Animates a custom transform.
296 Note that there is a restriction that only one transform animation can be applied on the same element at a time. Use the custom `transform-animation` to combine transform properties.
298 Shared element animations
300 * `hero-animation` Animates an element such that it looks like it scales and transforms from another element.
301 * `ripple-animation` Animates an element to full screen such that it looks like it ripples from another element.
304 * `cascaded-animation` Applys an animation to an array of elements with a delay between each.
