Mouse speed calculated on mouse move.
npm install mouse-speedCalculates mouse speed during the mousemove event.
``js
var MouseSpeed = require("mouse-speed");
var speed = new MouseSpeed();
speed.init(onCalcSpeed);
var onCalcSpeed = function() {
var speedX = speed.speedX;
var speedY = speed.speedY;
// do anything you want with speed values
console.log(speedX, speedY);
};
`
Create a new instance of mouse-speed in your project.
The speed values are accessed through the speedX and speedY properties on the instance.
The function passed to the instance will fire on every mousemove event.
`js
speed.destroy(onDestroyFunc);
var onDestroyFunc = function() {
console.log("destroyed");
};
`
To remove the event listener, call destroy` on the instance of mouse-speed.
An optional function can be passed that will be called when the event listener is removed
