AS2：鼠标移动太快扰乱功能

Question

我使用以下代码作为一组可滚动条的一部分，以便在拖动一个条时更改每个条相对于另一个条的关系。它会一直工作，直到用户尽可能快地滑动栏，然后数字就会出错......我确信这个功能无法像鼠标一样快速处理，但有人知道解决这个问题的方法吗？

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

这个问题仍然发生，我认为它无法避免，但我使用另一个函数（Slider_checker），每次鼠标滚动滚动条时，该函数都会在鼠标空闲 20 毫秒后运行一次（这 20 毫秒允许它确保 Food_Scroll_ratio 的所有循环都完成，这样就不会干扰它并节省一些 cpu 周期）。

这是我的最终代码：

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);
