Controlling the Frame Rate with requestAnimationFrame

Limiting the frame rate while using requestAnimationFrame can be a common want especially when coding Games where you want your animations and mechanics to not exceed a particular mark of frames per second. Let’s go through 2 ways of doing it.

Quick and Easy Way

Using setTimeout inside the rAF method is an easy way.

	#!/bin/bash -eux

	# Extracts and load PSX games that are distributed in .7z / .ape format.
	# Requires : ffmpeg, perl, cdemu, ecm2bin
	GAME_FOLDER="$1"
	EXTRACT_FOLDER=/tmp/game

	rm -rf "$EXTRACT_FOLDER"
	mkdir "$EXTRACT_FOLDER"
	cp -rf "$GAME_FOLDER"/* "$EXTRACT_FOLDER"

	#!/usr/bin/ruby
	# Create display override file to force Mac OS X to use RGB mode for Display
	# see http://embdev.net/topic/284710

	require 'base64'

	data=`ioreg -l -d0 -w 0 -r -c AppleDisplay`

	edids=data.scan(/IODisplayEDID.*?<([a-z0-9]+)>/i).flatten
	vendorids=data.scan(/DisplayVendorID.*?([0-9]+)/i).flatten

	import subprocess
	import re

	command = ['qdbus', 'org.kde.plasmashell', '/PlasmaShell', 'org.kde.PlasmaShell.evaluateScript']
	command.append("""
	var allDesktops = desktops();
	for (i=0;i<allDesktops.length;i++)
	{
	d = allDesktops[i];
	d.wallpaperPlugin = "org.kde.image";

	#!/bin/bash

	# !!WARNING!!
	# This will DELETE all efforts you have put into configuring nix
	# Have a look through everything that gets deleted / copied over

	nix-env -e '.*'

	rm -rf $HOME/.nix-*
	rm -rf $HOME/.config/nixpkgs
