如何修复子 class 中的参数计数不匹配错误？

Question

我有三个classes

基础形状

package 
{
    import flash.display.MovieClip;
    import flash.events.Event;
    import flash.system.System;

    public class BaseShape extends MovieClip
    {
        var isActive:Boolean;
        public function BaseShape(iX:int, iY:int)
        {
            x = iX;
            y = iY;
            isActive=true;
        }
        //Other function here
    }
}

五角星

package  {
    import flash.display.MovieClip;
    public class Pentangular extends BaseShape {
        public function Pentangular(iX:int, iY:int) {
            super(iX, iY);
        }
    }

}

PentangularClk

package  {

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

    public class PentangularClk extends Pentangular {
        public function PentangularClk(iX:int, iY:int) {
            super(iX, iY);
            Cross.visible=false;
            addEventListener(MouseEvent.CLICK, setActive);
        }
        private function setActive(e:MouseEvent):void{
            Tick.visible=!Tick.visible;
            Cross.visible=!Cross.visible;
            isActive=Tick.visible;
        }
    }
}

当我在主要（阶段）使用时class

package 
{
    import flash.display.MovieClip;
    import flash.events.KeyboardEvent;
    import flash.events.Event;
    import flash.ui.Keyboard;

    public class Main extends MovieClip
    {
        var myShape:Array=new Array();
        var toVertical:int=0;
        var toHorizontal:int=0;
        var pressedKeys:Object = { };
        public function Main()
        {
            SpeedShape.value=8;
            SpeedShape.minimum=0;
            SpeedShape.maximum=20;
            SpeedShape.stepSize= 1;
            RotationShape.value=8;
            RotationShape.minimum=1;
            RotationShape.maximum=20;
            RotationShape.stepSize= 1;
            myShape[0] = new Star(mainShape.width / 2,mainShape.height / 4);
//Next line makes this MovieClip
            myShape[1] = new PentangularClk(-1 * mainShape.width / 2,-1 * mainShape.height / 4);
            mainShape.addChild(myShape[0]);
            mainShape.addChild(myShape[1]);
            stage.addEventListener(KeyboardEvent.KEY_DOWN,moveShapeByKeyboard);
            stage.addEventListener(KeyboardEvent.KEY_DOWN,moveShapeByKeyboard,true);
            stage.addEventListener(KeyboardEvent.KEY_UP,stopShapeByKeyboard);
            stage.addEventListener(KeyboardEvent.KEY_UP,stopShapeByKeyboard,true);
        }
    }
}

我的库中有两个 MovieClips：

五边形
PentangularClk

PentangularClk 基于 Pentangular - 它具有 Pentangular 的所有形状。

我的 SWF 已启动并且可以使用。但是我看到了下一条消息：

ArgumentError: Error #1063: Argument count mismatch on Pentangular(). Expected 2, got 0.
    at flash.display::Sprite/constructChildren()
    at flash.display::Sprite()
    at flash.display::MovieClip()
    at BaseShape()
    at Pentangular()
    at PentangularClk()
    at Main()

我检查了发送给 classes 的参数类型。他们都还好。我不明白这条消息的原因。

Answer 1

你的函数 PentangularClk(iX:int, iY:int) 需要两个整数类型的变量，所以尝试（未测试）：

var int1 : int = (-1 * mainShape.width / 2);
var int2 : int = (-1 * mainShape.height / 4);

myShape[1] = new PentangularClk(int1, int2);

或者您可以这样尝试...

myShape[1] = new PentangularClk( int(-1 * mainShape.width / 2), int(-1 * mainShape.height / 4) );

Answer 2

感谢大家的建议。添加 PentangularClk 及其子形状 (Pentangular) 时，构造函数 Pentangular 被调用两次。

第二次调用构造函数时不带任何参数

所以，@Selirion的推荐很适合我。我刚刚设置了 iX 和 iY.

的默认值

现在看起来像

public function Pentangular(iX:int=0, iY:int=0)
