I loved the animations for the polygon ps4 review a few months back and decided to create a small library to re-create them.
Create a new Walkway instance with a supplied options object.
When you want to start animating call .draw on the returned instance
providing an optional callback that will be called when drawing is complete.
// Create a new instance
var svg = new Walkway(options);
// Draw when ready, providing an optional callback
svg.draw(callback);
// Options passed in as an object, see options below.
var svg = new Walkway({ selector: '#test'});
// Overwriting defaults
var svg = new Walkway({
selector: '#test',
duration: '2000',
// can pass in a function or a string like 'easeOutQuint'
easing: function (t) {
return t * t;
}
});
svg.draw();
// If you don't want to change the default options you can
// also supply the constructor with a selector string.
var svg = new Walkway('#test');
svg.draw(function () {
console.log('Animation finished');
});- selector (mandatory) - The selector of the parent element (usually will be a specific svg element)
- duration - Time the animation should run for, in ms. Default is 400.
- easing - Name of the easing function used for drawing. Default is 'easeInOutCubic'. You can also supply your own function that will be passed the progress and should return a value in the range of [0, 1];
All credit for the built-in easing functions go to gre from this gist.
Currently, this only works on path and line elements. Walkway
will also work with polyline elements when I have a few hours free.
