snap-animation-states

A Snap.svg plugin that lets you load and animate svgs using a simple schema.

Installation

Include JS

Include Snap.svg 0.4.1 and snap-animation-states.js in the footer. No JQuery needed.

<script type="text/javascript" src="js/snap.svg.js"></script>
<script type="text/javascript" src="js/snap-animation-states.js"></script>

Set HTML

Your SVGs need a container element. You just need to add whatever class you're calling your svg with to the element that will contain it.

<i class="icon-hamburger"></i><br> 
<i class="my-svg-selector"></i>    

Call the plugin

It's as simple as calling the plugin with the correct schema.

(function() {    
	SnapStates({ ...schema... })
})();

Schema

• selector: string css selector - ex: ".icon-hamburger"
• svg: string svg string or svg file reference
• easing: string "linear", "easein", "easeout", "easeinout", "backin", "backout", "bounce", "elastic"
• transitionTime: intTransition time is applied to each transform. A state with 3 transforms one after the other and a transitionTime of 500 ms will take a total of 1500 ms to finish
• initState: stringSet initState equal to the state you want to run when the plugin is called.
• states: obj Contains the states and transforms to be performed. Each state contains an array of transforms.
  • key: state name prop: array of transform objects
    • id: int/string/arr The id should be unique to its state. If you want the transform to start after a timeout, the id takes an array: [id, timeout:int]
    • waitFor: int/string/arr Set the waitFor property to the id of a transform that it should follow. For a timeout, waitFor takes an array: [id, timeout: int]
    • element: string Takes the css selector of the element that the transform is affecting.
    • x: int Takes an x coordinate relative to the elements starting position
    • y: int Takes a y coordinate relative to the elements starting position
    • r: int/array
      • r:180 rotates the element 180 degrees around its center
      • r:[180, 30, 30] rotates the element 180 degrees around the coordinates 30, 30 on the svg canvas
    • s: int/array
      • s:0.5 scales the element down to half its size.
      • s:[0.5, 1] scales the element down to half its size horizontally without affecting its vertical size.
      • s:[0.5, 0.5, 30, 30] scales the element down to half its size around the coordinates 30, 30 on the svg canvas
    • attr: obj Affect any svg attribute
    • path: string Represented by the "d" attribute in an svg. Learn more about paths.
    • drawPath: int/obj
      • int: percentage of path to draw. 0 is no path and 100 is the full path length
      • obj: {min: minPath max: maxPath} Randomize your path length using min and max
    • transitionTime: int/obj
      • int: transition time to override the base transition time
      • obj: {min: minTime max: maxTime} Randomize the transitionTime with a min and max
    • easing: string same easing options as previously shown. Useful if you have several types of easing you want to display from transform to transform
    • repeat: obj Will repeat the entire state from the point the repeat is called
      • loop :bool set an infinite loop
      • loopDuration :int end loop after a time
      • times: int loop the animation x times
• events:array of objects
  • event: string works with any javascript event
  • state: string/array
    • string: string matches name of state you want to run when the event happens
    • array: used for toggle events. ["state1", "state2"] can be toggled when the event happens
  • selector: string a css selector used to indicate where to watch for the event - ex: an svg inside an anchor tag. The anchor tag will receive the selector so that when the anchor is clicked the svg animation runs.
