Question

我有一些代码可以控制拖动mouseX轴时生成的图像和360度旋转。这一切都与我使用的代码完美配合。

我必须为不同的平台设计并扩大舞台的大小我在文档设置中按比例缩放到舞台复选框。

当鼠标按下时，旋转可以正常拖动图像，但是当你释放并开始再次拖动时，它不记得最后一帧并跳转到另一帧然后再次拖动？当我所做的只是改变一切的规模时，为什么它会这样跳？

请参阅代码使用

//ROTATION OF CONTROL BODY X
spinX_mc.stop();

var spinX_mc:MovieClip;
var offsetFrame:int = spinX_mc.currentFrame;
var offsetX:Number = 0;
var percent:Number = 0;

//Listeners
spinX_mc.addEventListener(MouseEvent.MOUSE_DOWN, startDragging);
spinX_mc.addEventListener(MouseEvent.MOUSE_UP, stopDragging);

function startDragging(e:MouseEvent):void
{   

    // start listening for mouse movement
    spinX_mc.addEventListener(MouseEvent.MOUSE_MOVE,drag);
    offsetX = stage.mouseX; 
}

function stopDragging(e:MouseEvent):void
{
    ("stopDrag")
    // STOP listening for mouse movement
    spinX_mc.removeEventListener(MouseEvent.MOUSE_MOVE,drag);
    // save the current frame number;

    offsetFrame = spinX_mc.currentFrame;

    removeEventListener(MouseEvent.MOUSE_DOWN, startDragging);
}

// this function is called continuously while the mouse is being dragged

function drag(e:MouseEvent):void
{
    trace ("Drag")
    // work out how far the mouse has been dragged, relative to the width of the spinX_mc
    // value between -1 and +1
    percent = (mouseX - offsetX) / spinX_mc.width;
    // trace(percent);

    // work out which frame to go to. offsetFrame is the frame we started from
    var frame:int = Math.round(percent * spinX_mc.totalFrames) + offsetFrame;

    // reset when hitting the END of the spinX_mc timeline
    while (frame > spinX_mc.totalFrames)
    {
        frame -=  spinX_mc.totalFrames;
    }
    // reset when hitting the START of the spinX_mc timeline
    while (frame <= 0)
    {
        frame +=  spinX_mc.totalFrames;
    }

    // go to the correct frame
    spinX_mc.gotoAndStop(frame);
}

通过更改

spinX_mc.addEventListener(MouseEvent.MOUSE_MOVE,drag);
offsetX = stage.mouseX;

到

spinX_mc.addEventListener(MouseEvent.MOUSE_MOVE,drag);
offsetX = mouseX;

我似乎解决了这个问题，一切都顺利进行。
