Simple game loop

Install

npm i --save gameloopjs

Usage

const gameloop = require('gameloopjs') // or import gameloop = require('gameloopjs') if you use typescript.

const loop = gameloop(() => {
  console.loog('step')
}, 30)

loop.run()

setTimeout(() => {
  loop.stop()
}, 5000)

In the above example func is called 30 times per second and is stopped after 5 seconds.

Set other fps

If you want to run func 60 times per sec, then do this:

const loop = gameloop(func, 60)

loop.run() // func is called 60 times per second

API

gameloop(func: () => void, fps: number)

This throws when it's called during it's already running.

loop.stop(): void
