Question

我正在尝试使用按钮编写主菜单。我有一个名为MenuAchievementsButton的类，在其构造函数中，它从文档类向下传递舞台宽度和舞台高度。当我追踪它时，它是正确的宽度/高度。

我正试图让按钮的高度为舞台高度/ 100.我已经尝试过这样做。高度=舞台高度/ 100，但每当我这样做时，它给我4倍的结果我想要的，甚至当我输入一个像5这样的数字并在Photoshop中测量px时。

此外，当我尝试移动对象时，存在类似的问题：当我想要它时，例如，向上和向下20px，结果是向下和向下80px。

感谢任何帮助！

    package menus {

import flash.display.MovieClip;


public class MenuAchievementsButton extends MovieClip {
    private var _stageWidth, _stageHeight:int;

    public function MenuAchievementsButton(stageWidth:int, stageHeight:int) {
        _stageWidth = stageWidth;
        _stageHeight = stageHeight;

        alpha = 1;
        rescaleMe();
        repositionMe();
        trace(_stageWidth, _stageHeight);
    }

    private function rescaleMe():void {
        var oldWidth = this.width;
        var oldHeight = this.height;

        this.height = _stageHeight/100;
        this.width = (this.height * oldWidth) / oldHeight;
    }

    private function repositionMe():void {
        this.x = 20;
        this.y = 20;
        trace(x,y,width,height);
        trace("Stage height is: ",_stageHeight,"Stage height divided by 100 is: ", _stageHeight/100, "And the object's height, which should be stageheight / 100 is:", this.height);
        //Gives Stage height is:  800 Stage height divided by 100 is:  8 And the object's height, which should be stageheight / 100 is: 8
        //Actually, though, it's 36px!
    }
}

}

代码似乎是正确的。那里没有问题。

是否在舞台上添加了该类的实例？或者在其他一些对象上？

看看你是否改变父母的规模，如下所示：

var parentMC:MovieClip=new MovieClip();
addChild(parentMC);

var rectangle:Shape = new Shape; // initializing the variable named rectangle
rectangle.graphics.beginFill(0xFF0000); // choosing the colour for the fill, here it is red
rectangle.graphics.drawRect(0, 0, 100,100); // (x spacing, y spacing, width, height)
rectangle.graphics.endFill(); // not always needed but I like to put it in to end the fill
parentMC.addChild(rectangle); // adds the rectangle to the stage

trace(rectangle.width) // result 100

parentMC.scaleX=2;
trace(rectangle.width) // result 100 altough it looks like it has 200

as3 MovieClip无法正确缩放
