TimeLine //JavaScript Class

jonasraoni (Jonas Raoni Soares Silva) — Sun, 30 Mar 2008 16:49:21 GMT

Simulates the Adobe Flash timeline. You define the amount of frames, the speed in fps (frames per second) and, at each frame passage an event is called, useful for animations.

[UPDATED CODE AND HELP CAN BE FOUND HERE]

TimeLine = function(fps, f){

	this.fps = fps, this.frames = f;

};

with({o: TimeLine, $: TimeLine.prototype}){

	o.timers = [];

	$.running = !!($.current = +(o.timer = $.time = null));

	o.run = function(){

		var o = this;

		o.timer || (o.timer = setInterval(function(){

			for(var h, d = +(new Date), t = o.timers, i = t.length; i--;){

				(!t[i].running || ((d - t[i].time) / (1e3 / t[i].fps) > t[i].current + 1 &&

				t[i].onframe(++t[i].current), t[i].current >= t[i].frames)) &&

				(h = t.splice(i, 1)[0], h.stop(1));

			}

		}, 1));

	};

	$.start = function(c){

		var o = this, t = TimeLine;

		if(o.running) return;

		o.running = true, o.current = c || 0;

		o.time = new Date, o.onstart && o.onstart();

		if(!o.onframe || o.frames <= 0 || o.fps <= 0)

			return o.stop(1);

		t.timers.push(this), t.run();

	};

	$.stop = function(){

		var o = this;

		o.running = false;

		if(!TimeLine.timers.length)

			TimeLine.timer = clearInterval(TimeLine.timer), null;

		arguments.length && o.onstop && o.onstop();

	};

}

Example





25 fps

12 fps



TimeLine working together with the ease in quad function.
