Run JavaScript code every second with rAF.js? -


i moved using settimeout requestanimationframe per post at: http://paulirish.com/2011/requestanimationframe-for-smart-animating/

how can set code inside animation() loop execute every second?

i like:

animate() {   if(playgame) {     requestanimframe(animate);   }    var time = new date().gettime();    if(time % 1000 <= 10) {     // code run ~every second   }    // need fix this, executes fast, need add score    // every 100 milliseconds (player must stay in zone 2 seconds win)   if(playerinzone()) {     gamescore++;     if(gamescore >= 100) {       endgame();     }   } else {     gamescore = 0;   }  }

i'm not sure if calling time , performing modulus right way? in way change gamescore code fire every (for example) 200 milliseconds?

note:
use code @ top of javascript file:

window.requestanimframe = (function(){   return  window.requestanimationframe       ||           window.webkitrequestanimationframe ||           window.mozrequestanimationframe    ||           window.orequestanimationframe      ||           window.msrequestanimationframe     ||           function(/* function */ callback, /* domelement */ element){             window.settimeout(callback, 1000 / 60);           }; })();

but i've included raf.js in file, unsure use:

// http://paulirish.com/2011/requestanimationframe-for-smart-animating/ // http://my.opera.com/emoller/blog/2011/12/20/requestanimationframe-for-smart-er-animating  // requestanimationframe polyfill erik möller. fixes paul irish , tino zijdel  // mit license  (function() {     var lasttime = 0;     var vendors = ['ms', 'moz', 'webkit', 'o'];     for(var x = 0; x < vendors.length && !window.requestanimationframe; ++x) {         window.requestanimationframe = window[vendors[x]+'requestanimationframe'];         window.cancelanimationframe = window[vendors[x]+'cancelanimationframe'] || window[vendors[x]+'cancelrequestanimationframe'];     }      if (!window.requestanimationframe)         window.requestanimationframe = function(callback, element) {             var currtime = new date().gettime();             var timetocall = math.max(0, 16 - (currtime - lasttime));             var id = window.settimeout(function() { callback(currtime + timetocall); },               timetocall);             lasttime = currtime + timetocall;             return id;         };      if (!window.cancelanimationframe)         window.cancelanimationframe = function(id) {             cleartimeout(id);         }; }());

when requestanimationframe called "current time" sent in milliseconds, this:

var lasttime = 0;  animate(currenttime) {   if (currenttime >= lasttime + 1000)  {      // 1 second has passed, run code here       lasttime = currenttime;   }     if(playgame) {     requestanimationframe(animate);   } }
