How can I use it?

The following code will create an sector on map, assuming a Leaflet.Map called map.

var sector = L.animatedSector([30.661057, 104.081757], {
	radius: 500000,			// meters
	fillColor: '#ff0000',
	fillOpacity: 0.6,
	directionAngle: 90,		// the direction sector point to
	viewAngleRange: 90,		// the angle of sector
})

sector.addTo(map); 

How do I animate the sector ?

/**
 * AnimatedSector.pendulum(angleStep, minAngle, maxAngle)
 *  angleStep: angle changes during every interval
 *  minAngle: the minimum angle of pendulum animation
 *  maxAngle: the maximum angle of pendulum animation
 */
sector.pendulum(4, 30, 150);

/**
 * AnimatedSector.stopPendulum()
 */
sector.stopPendulum();

/**
 * AnimatedSector.spin(angleStep)
 *  angleStep: angle changes during every interval
 */
sector.spin(4);

/**
 * AnimatedSector.stopSpin()
 */
sector.stopSpin();

How do I reset the sector's style ?

/**
 * AnimatedSector.setStyle(options)
 */
sector.setStyle({
	radius: 400000,
	fillColor: '#ffff00',
	fillOpacity: 0.4,
	fillGradient: true,
	viewAngleRange:100,
	border: 1,          
	borderColor: '#ff0000',
	borderDashLine: true
});
