Ticker

The ticker centralizes luge’s requestAnimationFrame callbacks.

You can attach your own functions, they will be called at each requestAnimationFrame call.

Usage

const myCallback = () => { ... }
luge.ticker.add(myCallback, this)
luge.ticker.remove(myCallback, this)

If you are already using a requestAnimationFrame loop in your code or if you are using a third-party library that uses it (gsap for instance) you can call the tick method manually like so:

// Tell luge to use an external ticker
luge.settings({ticker: {external: true}})

function myRaf () {
  // Call tick method in your raf function
  luge.ticker.tick()

  requestAnimationFrame(myRaf)
}
myRaf()

Or for gsap:

luge.settings({ticker: {external: true}})
gsap.ticker.add(luge.ticker.tick)
