checking actual framerate

[somaBoy MX]

Hi,


I made a site which uses horizontal scrolling navigation (check:
[url]http://www.esthervenrooy.com[/url]) Not surprisingly, the scrolling is far from
smooth on older machines. I would like to be able to test the actual
framerate of the movie on the client machine, so when I detect a very slow
fps I can just make the navigation skip to the next section without
scrolling...

Anybody have function/idea for that?

AFAIK there is no way to get the framerate of an swf. I saw some experiment to calculate an estimate of fps or to estimate the capacilities of client's machines, but ... I don't remember where sorry.

Perhaps you can use the getTimer()-function to find out how long an interval
of a few frames takes?

....but I dont know!

When you say older machines I assume you mean machines with less RAM. If that is true it might help you to remember that flash is an embedded object and html can call upon several programs (including itself) to check system info before you load any swf object.

I'm pretty sure there is an extension in the Exchange that will do this.
look up zShowFPS in the Exchange

Here's one I made earlier. Of course, if you don't need to actuall *display*
the frame rate, you can get rid of all the textField stuff and just use the
variable values.

//--------------------------------------------------------------------------
-----------
// Creates timer a rough frames per second counter...
//--------------------------------------------------------------------------
-----------
//create clip
_root.createEmptyMovieClip("counter", 2);
//set textformat
counterText = new TextFormat();
counterText.font = "courier";
counterText.size = 12;
counterText.bold = true;
counterText.color = 0xFF0000;
//create text field
counter.createTextField("label", 1, 10, 10, 0, 0);
counter.label.autoSize = "left";
counter.label.text = "fps: ";
counter.label.setTextFormat(counterText);
counter.createTextField("fps", 2, counter.label._width, 10, 0, 0);
counter.fps.autoSize = "left";
counter.fps.type = "dynamic";
counter.fps.variable = "_root.counter.fpsDisp";
counter.fps.setNewTextFormat(counterText);
counter.startTime = getTimer();
//posotion
counter._y -= counter.label._height*2;
//enterframe handler
counter.onEnterFrame = function() {
this.allTime = getTimer()-this.startTime;
this.fpsDisp = Math.round(1000/this.allTime);
this.startTime = getTimer();
};

//--------------------------------------------------------------------------
-----------
// END TIMER
//--------------------------------------------------------------------------
-----------

Thanks for your help, all of you...

I did the following:

Made a movieClip with some complex alpha tweened animation which plays
offstage.

I check with getTimer() how long it takes for the movie to complete. If the
value returned is more than double the time it should take at the movie's
author-time framerate, I disable the animated navigation.

Seems to do the job.
