Question

添加了增长和缩小按钮代码后，我的代码出现问题。它在告诉我

“C：\ Users \ Dan \ Desktop \ Flash \ Interactive Story Book \ Main.as，Line 28 1120：访问未定义的属性onShrinkButtonClick。”

“C：\ Users \ Dan \ Desktop \ Flash \ Interactive Story Book \ Main.as，第29行1120：访问未定义的属性onGrowButtonClick。

实例名称正确，与我的AsLinkage或对象名称不同。

package 
{

import flash.display.MovieClip;
import flash.events.MouseEvent;

public class Main extends MovieClip
{

    var startPage:StartPage;
    var hillPage:HillPage;
    var lakePage:LakePage;

    public function Main()
    {
        startPage = new StartPage();
        hillPage = new HillPage();
        lakePage = new LakePage();
        addChild(hillPage);

        //Add event listeners
        startPage.buttonHill.addEventListener(MouseEvent.CLICK, onHillButtonClick);
        startPage.buttonLake.addEventListener(MouseEvent.CLICK, onLakeButtonClick);

        hillPage.shrinkButton.addEventListener(MouseEvent.CLICK, onShrinkButtonClick);
        hillPage.growButton.addEventListener(MouseEvent.CLICK, onGrowButtonClick);
    }
    //Event handlers
    function onHillButtonClick(event:MouseEvent):void

    }

    }
    function onStartButtonClick_lake(event:MouseEvent):void

        if(hillPage.cat.y < 90)
        {
            hillPage.cat.y =90
        }
    }
    function onDownButtonClick(event:MouseEvent):void
    {
        hillPage.cat.y +=15
        if(hillPage.cat.y >190)
        {
            hillPage.cat.y =190
        }
    function onGrowButtonClick(event:MouseEvent):void
    {
        hillPage.cat.scaleX +=0.1;
        hillPage.cat.scaleY +=0.1;
    }
    function onShrinkButtonClick(event:MouseEvent):void
    {
        hillPage.cat.scaleX -=0.1;
        hillPage.cat.scaleY -=0.1;
    }


    }
}
}

Answer 1

您之前的功能（function onDownButtonClick(event:MouseEvent):void）缺少关闭}。结果onGrowButtonClick成为onDownButtonClick的内部函数，因此在外部不可见。

注意：你在结尾处放置了大量的括号，因此整个文件实际上有正确数量的大括号，只有onGrowButtonClick和onShrinkButtonClick位于onDownButtonClick内。您的代码目前类似于：

function onDownButtonClick(event:MouseEvent):void
{
   function onGrowButtonClick() ...;
   function onShrinkButtonClick() ...;
}

建议：找到带有大括号匹配的好文本编辑器。 ActionScript接近于JavaScript - 所以找到一个好的可以工作。
