set Interval problem

[Lost Student]

hey i have this block of code:

setInterval(function () {
angle += 0.045;
_parent.clock.back.arm._rotation = angle;
timer = i;
}, 1);

it moves an arm on a clock very smoothly, works fine in a SWF but runs far too slowly when in a browser, any ideas would help alot. im lost..

cheers

Make its rotation change 0.25 degree per 5 msec.

I believe 0.25 degree is the unit that Flash handles rotation.

no matter what settings i use it always runs too fast in the broswer.. could it be that set intercal uses cpu speed to work and the cpu is under pressure therefore slower?

this is the arm moving 6 degrees every second, not ideal bu this way it keeps the time perfectly.. why not so if i use .00 numbers..?

Oh, that is what you mean by "slow" !

Both setInterval and onEnterFrame are not evoked at precisely accurate interval. A movie with FPS 12 is not going to be played acurately for one frame per 83.3333333333333 msec;

Yes, the interval is partly affected by the working load of CPU.

If you want to make a clock, you get to peek the system clock.

so why does it run fine in a swf on its own when in a broswer it runs too slow? does the broswer have to keep up with the timing of the swf?
