Settle a number towards another number over time with an overridable tween.
npm install settler
var Settler = require('settler');
var settler = new Settler();
settler.on('frame', function(value){
console.log(value);
});
settler.on('settle', function(){
console.log('done');
});
settler.settle(100);
// Will log a few times from 100 to 0.You can cancel a settle with .cancel() and listen for the event:
settler.on('cancel', function(value){
console.log('cancled');
});
settler.cancel();You can override any defaults on the instance via the constructor or just manually:
var Settler = require('settler');
var settler = new Settler({
target: 50,
tween: function(value, distance){
return distance / 10; // get one tenth closer to the target each 'frame'
}
});
// later...
settler.target = 300;And more, read the source for more interesting usage.
