I optimized requestAnimationFrame calls by prebinding the animation function
The normal flow is
function animate() {
requestAnimationFrame(animate);
// do render stuff
chicken.position.x++;
}
animate();
However when you encapsulate your code into a class
Normal Animation Step in Class
animate() {
requestAnimationFrame(this.animate.bind(this));
// do render stuff
this.chicken.position.x++;
}
// somewhere else
this.animate.call(this);
I noticed you can get a measurable execution speedup by prebinding the animate function to do this
Optimized Animation Step
animate() {
requestAnimationFrame(this.animate_binded);
// do render stuff
this.chicken.position.x++;
}
// somewhere else
this.animate_binded = this.animate.bind(this);
this.animate();
I don't have heap analysis tools but I observed a measurable and repeatble drop in time spent scripting and rendering.
Can anyone help me confirm? This might be obvious but I don't think it hurts to point out that you can optimze away the bind step.
