API

• new Clock([useInterval=false])
• clock.start([useInterval=false])
• clock.stop()
• clock.tick()
• clock.elapsedTime
• clock.deltaTime
• clock.currentTime

Usage example

There's two ways you can use clock.js: manual or automatic.

Automatic

By initializing Clock with true as the first argument, a interval will be created, in which tick() is called 60 times per second.

var clock = new Clock(true);

You can also call start(true) to create the interval.

var clock = new Clock();
clock.start(true);

Manual usage

You call tick() manually in your existing loop.

var Clock = require('clock.js');
var clock = new Clock();

setInterval(function() {
  clock.tick();
  console.log("Delta time: ", clock.deltaTime);
  console.log("Elapsed time: ", clock.elapsedTime);
  console.log("Current time: ", clock.currentTime);
}, 1000 / 60);
