嘿，我建立自定义的滚动框。当我向上滚动，此框滚动元素正在下降，当我向下滚动 - 滚动元件正在上升）。我whant扭转这一机制。我该怎么办呢？ 下面我code鼠标

 进口flash.events.MouseEvent;

功能handleMouseWheel（事件：MouseEvent）方法：无效{
    如果（（event.delta大于0＆安培;＆安培; box_mc.y＆所述; 171）||（event.delta＆℃，安培;＆安培; box_mc.y＆GT; 135））
    {

        box_mc.y = box_mc.y +（event.delta * 3）;
        sb.thumb.y = sb.thumb.y +（event.delta * 13）;

        跟踪（box_mc.y）;
        跟踪（event.delta）;

    }
}
stage.addEventListener（MouseEvent.MOUSE_WHEEL，handleMouseWheel）;
 

解决方案

所有你需要做的就是反转（在其中滚动或方向）的delta值：

  IF（（event.delta＆GT; 0安培;＆安培; box_mc.y＆LT; 171）||（event.delta℃，与功放;＆安培; box_mc.y＆GT; 135））
{

    box_mc.y = box_mc.y +（-event.delta * 3）;
    sb.thumb.y = sb.thumb.y +（-event.delta * 13）;

    跟踪（box_mc.y）;
    跟踪（event.delta）;

}
 

通知所有我做的是把一个减号在前面的 event.delta 的值。

Hey i built custom scroll box. When i scroll up on this box scrolling element is going down and when i scroll down - scrolling element is going up ;). I whant to reverse that mechanism. how can i do it ? Below my code for mouse

import flash.events.MouseEvent;

function handleMouseWheel(event:MouseEvent):void {
    if ((event.delta > 0 && box_mc.y < 171) || (event.delta < 0 && box_mc.y > 135)) 
    {

        box_mc.y = box_mc.y + (event.delta * 3);
        sb.thumb.y = sb.thumb.y + (event.delta * 13);

        trace(box_mc.y);
        trace(event.delta);

    }
}
stage.addEventListener(MouseEvent.MOUSE_WHEEL, handleMouseWheel);

All you need to do is invert the delta value (or the direction in which you scroll):

if ((event.delta > 0 && box_mc.y < 171) || (event.delta < 0 && box_mc.y > 135)) 
{

    box_mc.y = box_mc.y + (-event.delta * 3);
    sb.thumb.y = sb.thumb.y + (-event.delta * 13);

    trace(box_mc.y);
    trace(event.delta);

}

Notice all I have done is put a minus symbol in front of the event.delta value.
