Animation Plugin for Leaflet.js

General information

A leaflet plugin which allows users to apply animation.

Downloads

NPM

npm install --save leaflet.motion

YARN

yarn add leaflet.motion

Usage

Include script:

<script src="dist/leaflet.motion.min.js"></script>

Main options:

L.motion.polyline([], options, motionOptions, markerOptions).addTo(map); //  as L.polyline
L.motion.polygon([], options, motionOptions, markerOptions).addTo(map); //  as L.polygon
L.motion.group([], options).addTo(map); //  as L.featureGroup - to run all animation at same time
L.motion.seq([], options).addTo(map); //  as L.featureGroup - to setup seq for animations.

Options:

You can pass a number of options to the plugin to control various settings.

Default control options

Option	Type	Default	Description
pane	Pane	'polymotionPane'	Default pane

Motion options

Option	Type	Default	Description
auto	Boolean	false	Indicates auto start animation when motion object added to the map
easing	L.Motion.Ease	L.Motion.Ease.linear	Animation strategy
speed	Number	0	Motion speed in KM/H
duration	Number	0	Motion duration in ms, 0 means no animation, instant rendering on motionStart()

Marker options

All MarkerOptions that you can add to any marker + one more:

Option	Type	Default	Description
removeOnEnd	Boolean	false	Removes marker from map on motion end
showMarker	Boolean	false	Add marker to the map on first line point when motion just added(start can be delayed) to the map

Here's an example of passing through some options:

L.motion.polyline([[50,0], [60,10]], {
	color: "transparent"
}, {
	auto: true,
	duration: 3000,
	easing: L.Motion.Ease.easeInOutQuart
}, {
	removeOnEnd: true,
	showMarker: true,
	icon: L.divIcon({html: "<i class='fa fa-car fa-2x' aria-hidden='true'></i>", iconSize: L.point(27.5, 24)})
}).addTo(map);

Public methods

L.motion.*

Public methods in all motion objects:

motionStart() // to start motion.
motionStop() // to stop motion.
motionPause() // to pause motion.
motionResume() // to resume paused motion.
motionToggle() // to pause motion, if it's running. To start motion if it's not. Also will resume motion if it was paused.
getMarkers() // to get all markes from all motion sub components. Will return multi-dimensional array of markers.

L.motion.polyline and L.motion.polygon

Additional methods in polyline and polygon

motionDuration(duration) // - expected duration for motion in milliseconds, can be used after motion is created.
motionSpeed(speed) // - expected motion speed in KM/H, can be used after motion is created.
addLatLng(latLng) // - allows to add additional point in the end for the motion animation.
getMarker() // returns marker (if markerOptions is passed on creation) to attach needed behavior. Marker will be added to the map only during animation

Motion Events

Event	Value	Description
L.Motion.Event.Started	{ layer }	Fires on motion stated on root element only
L.Motion.Event.Paused	{ layer }	Fires on motion paused on root element only
L.Motion.Event.Resumed	{ layer }	Fires on motion resumed on root element only
L.Motion.Event.Ended	{ layer }	Fires on motion ended on root element only
L.Motion.Event.Section	{ layer }	Fires on each motion section change in L.Motion.Seq starting with first one
