Question

I am using the following code as part of a set of scrollable bars to change each bar in relation to another when one is dragged. It works until the user swipes the bar as fast as possible then the numbers go wrong… I’m sure this is the function unable to process as fast as the mouse but anyone know a way around this?

onClipEvent (load) {
    Symptoms_sliders = new Array(this._parent.slider1.slider, this._parent.slider2.slider, this._parent.slider3.slider, this._parent.slider4.slider, this._parent.slider5.slider);
    Food_sliders = new Array(this._parent.slider6.slider, this._parent.slider7.slider, this._parent.slider8.slider, this._parent.slider9.slider);
    for (i=0; i<Food_sliders.length; i++) {
        Food_sliders[i]._y = 75;
    }
    is_scrolling = 0;
    function Food_scroll_ratio() {
        init_scroll_diff = init_scroll_num-init_scroll._y;
        Slider_ratio = new Array();
        totalLeft = init_scroll_num;
        while (_global.init_moved != init_scroll._y) {
            for (i=0; i<Food_sliders.length; i++) {
                if (Food_sliders[i] != init_scroll) {
                    slider_pos = Food_sliders[i]._y;
                    percentageOf = ((100-init_slider_pos[i])/totalLeft)*100;
                    percentageMultiplier = 100/percentageOf;
                    trace(percentageMultiplier);
                    if (init_scroll_num == 0) {
                        scroll_change = Math.round(Math.abs(init_scroll_diff/3));
                    } else {
                        scroll_change = Math.round(Math.abs(init_scroll_diff)/percentageMultiplier);
                    }
                    if (percentageOf == Infinity) {
                        Food_sliders[i]._y = 100;
                    } else if (init_scroll_diff>0) {
                        Food_sliders[i]._y = init_slider_pos[i]+scroll_change;
                    } else if (init_scroll_diff<0) {
                        Food_sliders[i]._y = init_slider_pos[i]-scroll_change;
                    }

                }
            }
            _global.init_moved = init_scroll._y;

        }
    }
}
onClipEvent (mouseMove) {
    for (i=0; i<Food_sliders.length; i++) {
        Food_sliders[i].onPress = function() {
            startDrag(this, false, 0, 100, 0, 0);
            init_scroll_num = this._y;
            init_scroll = this;
            is_scrolling = 1;
            init_slider_pos = new Array();
            init_slider_pos.push(Food_sliders[0]._y);
            init_slider_pos.push(Food_sliders[1]._y);
            init_slider_pos.push(Food_sliders[2]._y);
            init_slider_pos.push(Food_sliders[3]._y);
        };
        Food_sliders[i].onRelease = Food_sliders[i].onReleaseOutside=function () {
            stopDrag();
            is_scrolling = 0;
        };
    }
    if (is_scrolling == 1) {
        Food_scroll_ratio();
    }
}

Answer 1

This problem still occurs and I don’t think it can be avoided but I use another function (Slider_checker) that runs once 20ms after the mouse is idle everytime the mouse scrolls a scrollbar (the 20ms allows it to ensure that all loops of Food_Scroll_ratio are finished so nothing interferes with it and saves some cpu cycles).

Here is my final code:

onClipEvent (load) {
    Symptoms_sliders = new Array(this._parent.slider1.slider, this._parent.slider2.slider, this._parent.slider3.slider, this._parent.slider4.slider, this._parent.slider5.slider);
    Food_sliders = new Array(this._parent.slider6.slider, this._parent.slider7.slider, this._parent.slider8.slider, this._parent.slider9.slider);
    for (i=0; i<Food_sliders.length; i++) {
        Food_sliders[i]._y = 75;
    }
    is_scrolling = 0;
    Slider_check_interval = 0;
    var mouseTimerID:Number;
    var delay:Number = 50;
    var mouseMoveListener = new Object();
    mouseMoveListener.onMouseMove = function() {
        clearInterval(mouseTimerID);
        mouseTimerID = setInterval(Slider_checker, delay);
    };
    Slider_checker = function () {
        while (Slider_check_interval == 1) {
            count = 0;
            for (i=0; i<Food_sliders.length; i++) {
                count += 100-Food_sliders[i]._y;
            }
            if (count != 100 && count != 0) {
                mxm = Food_sliders[0];
                for (i=0; i<Food_sliders.length; i++) {
                    if (Food_sliders[i]._y<mxm._y) {
                        mxm = Food_sliders[i];
                    }
                }
                if (count>100) {
                    mxm._y += count-100;
                }
                if (count<100) {
                    mxm._y -= 100-count;
                }
            }
            Slider_check_interval = 0;
        }
    };


    Mouse.addListener(mouseMoveListener);
    function Food_scroll_ratio() {
        init_scroll_diff = init_scroll_num-init_scroll._y;
        totalLeft = init_scroll_num;
        Slider_check = new Array();
        for (i=0; i<Food_sliders.length; i++) {
            if (Food_sliders[i] != init_scroll) {
                slider_pos = Food_sliders[i]._y;
                percentageOf = ((100-init_slider_pos[i])/totalLeft)*100;
                percentageMultiplier = 100/percentageOf;
