图像平移窗口调整大小问题

Question

我在 Flash 中有这个文档，我希望图像可以通过鼠标移动进行平移。当我测试电影时，它运行正常，没有任何问题。但是当我调整窗口大小以调整大图像的位置时，一切都出错了。

这是代码（Actionscript 2.0）：

var boundX:Number = bigPic._x+activator._x*(bigPic._width/activator._width);
var diffX:Number = bigPic._width-activator._width;
var easeSpeed:Number = 7;

function resizeHandler():Void {
    g1_mc._x = 0;
    g1_mc._y = 0;
    g1_mc._height = Stage.height;
    g1_mc._width = (Stage.width-activator._width)/2;
    g2_mc._y = 0;
    g2_mc._height = Stage.height;
    g2_mc._width = (Stage.width-activator._width)/2;
    g2_mc._x = Stage.width-g2_mc._width;
    activator._x = g1_mc._width;
    //trace('bigPic' + bigPic._x);
    //trace('activatorx' + activator._x);
    boundX = bigPic._x+activator._x*(bigPic._width/activator._width);
    diffX = bigPic._width-activator._width;
    var divX:Number = _xmouse / activator._width;
    var moveX:Number = divX*diffX;
}

function activate():Void {
    var divX:Number = _xmouse / activator._width;
    var moveX:Number = divX*diffX;
    trace(bigPic._x);
    bigPic._x += (boundX-moveX-bigPic._x) / easeSpeed;
    //trace('DIVX' + divX);
    /*trace('boundX' + boundX);
    trace('moveX' + moveX);*/
}

activator.onRollOver = function():Void {
    addEnterFrameEvent();
};
activator.onRollOut = function():Void {
    removeEnterFrameEvent();
};
function addEnterFrameEvent():Void {
    this.onEnterFrame = activate;
}
function removeEnterFrameEvent():Void {
    delete this.onEnterFrame;
}
var stageListener:Object = new Object();
stageListener.onResize = function():Void {
    resizeHandler();
    delete _root.onEnterFrame;
};
Stage.addListener(stageListener);
stageListener.onResize();
Stage.scaleMode = "noScale";
Stage.align = "TL";

我认为，您看到的调整大小错误是因为您调用激活函数时没有为图像移动和设置边界。图像不断增加/减少它的 x 坐标。

您需要做的就是添加一个条件来检查图片是否超出框架（我想这就是您所指的错误）&如果是，则将 x 坐标设置为最大/最小限制...类似这样：（到 activate() 函数的末尾）

var MinimumX:Number = Stage.width - bigPic._width;
var MaximumX:Number = 0;

if(bigPic._x < MinimumX)  bigPic._x = MinimumX;
if(bigPic._x > MaximumX)  bigPic._x = MaximumX;
