To have a speed bar in Flash

Question

I want this

which I found in a animation about a heart

One manual here but too little details and very basics. ActionScript 3 most probably the latest programming language in Flash, but I cannot find here, for instance the function changeFps.

How can you have such a speed bar for an animation? Any package for this?

Answer 1

With a component Slider named slider on your stage:

import fl.events.SliderEvent;

var val:Number = 30;

slider.value = val;
slider.maximum = 100;
slider.minimum = 20;

myFps.text = val + " fps";
stage.frameRate = val;

slider.addEventListener(SliderEvent.THUMB_DRAG, changeFps);

function changeFps(e:SliderEvent):void {
    val = e.target.value;
    stage.frameRate = val;
    myFps.text = val + " fps";
}
