In a previous post, timing inconsistencies using requestAnimationFrame were suggested to be solved with an infinite requestAnimationFrame loop e.g. as follows. function workaroundLoop() { requestAnimationFrame(workaroundLoop); }; I actually tested this with an oscilloscope, and this looping does nicely improve timing precision in all browsers (not only Chrome, as suggested in that post). The new problem ..

According to Zero-cost async stack traces V8 uses the Promise reference in the microtask to reconstruct an "async stacktrace". I assume similar techniques are also used in the debugger, which also shows an "async stack". However when debugging a "pseudorecursive function", like e.g. this one using requestAnimationFrame: (function tick() { requestAnimationFrame(tick); })(); then Chrome also ..

I have an infinitely long webpage (it loads new chunks in when the page gets x distance from the bottom). I want to implement, via Javascript, smooth automatic scrolling of this webpage in a way that minimizes jitter/jumpiness. I’ve tried two primary methods: setInterval() and requestAnimationFrame(). So far, setInterval() seems to give the best visual ..

little question. After googling how to do this for 8 hours a day, nothing. Please let me know how to stop a requestAnimationFrame: simply, just temporarily pause the animation: <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width" /> <head> <title>Parking Master LVL. 1</title> </head> <body> <h3 id="header-style">Parking Master</h3> <p class="paraGraph1">How to play:</p> <ol id="directions"> <p>1. drive into ..

So, I’m having an issue with figuring out how to pause and (most importantly) unpause my simulation. When I press play, I call a function called animate(). I only call it once, so naturally inside animate() I call requestAnimationFrame(animate) for it to loop as usual: function animate() { idAnimate = requestAnimationFrame(animate); (…more code…) } Note ..

I am experimenting with performant scrolling in React, and trying to really get to grips with requestAnimationFrame, in particular how it works in relation to the React render lifecycle. Consider the following code: function App() { const navRef = useRef(null); const [width, setWidth] = useState(100); useLayoutEffect(() => { function adjustWidth(pos) { console.log("scrollY is ", pos); ..
