[AS3] trying to control the frame rate on a movie clip

[Race Bannon]

I'm trying to control the frame rate on a movie clip ( i want the movie to flash at a speed controled by a knob) currently i have a tweened time line that fades in and out over the course of 20 frames. and the knob i have to control it is set to play that movie clip and set the frame rate at the same time. i have placed a trace statement on the knob rotation and the frame rate of the second clip. they both seem to show a decreas and increase of rate and angle as i turn the knob but vissually it looks same. any ideas? (i have enclosed just a part of my knob rotation code it is ugly i know i should have done an array) thank you for the help

 

his.fan_knob.addEventListener(Event.ENTER_FRAME, fan3);
fan_knob.buttonMode = true;
function fan3(evt:Event):void {
	if (this.ok) {
		trace("knob "+ fan_knob.rotation);
		var xVar = this.mouseX-fan_knob.x;
		var yVar = this.mouseY-fan_knob.y;
		MovieClip(root).texting.gotoAndStop(9);
		fan_knob.rotation = Math.max(0, Math.min(180, Math.abs(-(Math.atan2((yVar), -(xVar))*(180/Math.PI)))));
	
	} if (0 < fan_knob.rotation && fan_knob.rotation < 20 && (0 < MovieClip(root).hvac_knob.hvac_knob.rotation && MovieClip(root).hvac_knob.hvac_knob.rotation < 96) && (MovieClip(root).AC_Heat.currentFrame == 3)) {
		MovieClip(root).cool.cool.gotoAndPlay(10);
		MovieClip(root).cool.cool.frameRate =5;
	} else if (20 < fan_knob.rotation && fan_knob.rotation < 40 && (0 < MovieClip(root).hvac_knob.hvac_knob.rotation && MovieClip(root).hvac_knob.hvac_knob.rotation < 96) && (MovieClip(root).AC_Heat.currentFrame == 3)) {
		MovieClip(root).cool.cool.gotoAndPlay(10);
		MovieClip(root).cool.cool.frameRate =10;

I'm not so sure, but i think that MC speed isn't important. It uses the main timeline framerate. But as i said , i'm not so sure, and i can't test it right now. So test it in new movie and see if the MC framerate is controled by main timeline framerate.

i think you are right about the movie using the main time line rate but i want to try to change the frame rate of a nested movie clip. does anybody know if that is possible?

Ok, you are right. The frameRate property only works for the entire stage. Individual MovieClips cannot have independent frame rates.

oh well
any idea which direction i should research to figure out how to make it look like a knob is increasing the flashing of something?

[MyFriendIsATaco]

you could always attempt to simulate things using a Timer to emulate a different frame rate. If you are doing that, I would suggest setting your stage frame rate to at least the highest possible frame rate. That way you can simulate a slower rate better.

^ yeah, that should work.

ok good idea and thank you for the heads up on the frame rate settings. i will work on that today, and try not to bug you guys
