Actionscript 3 按钮不起作用

Actionscript 3 按钮不起作用,actionscript-3,Actionscript 3,我有以下问题/错误: 我创建了一个自定义按钮类(称为CustomBlitButton),其中定义了一个按钮。按钮的翻滚状态在CustomScreen类中定义。这是因为自定义屏幕包含一个或多个按钮。我可以在使用CustomScreen类的createButton函数时创建一个按钮 因此,如果我想制作一个带有菜单的屏幕,即几个按钮,我会这样做(这只是一个摘录): 但它不起作用!:(屏幕上出现多个按钮,每个按钮都有自己的eventListener,但当我将鼠标移到最后一个按钮上时,只有我创建的最后一个

我有以下问题/错误:

我创建了一个自定义按钮类(称为CustomBlitButton),其中定义了一个按钮。按钮的翻滚状态在CustomScreen类中定义。这是因为自定义屏幕包含一个或多个按钮。我可以在使用CustomScreen类的createButton函数时创建一个按钮

因此,如果我想制作一个带有菜单的屏幕,即几个按钮,我会这样做(这只是一个摘录):

但它不起作用!:(屏幕上出现多个按钮,每个按钮都有自己的eventListener,但当我将鼠标移到最后一个按钮上时,只有我创建的最后一个按钮会更改其颜色。当鼠标移到其他按钮上时,所有其他按钮都不会更改其颜色

请问,有人能帮我解决这个问题吗?非常感谢。:)

这是定义自定义按钮滚动状态的自定义屏幕的代码

    }

}

}
这是定义按钮的代码:

package com.framework_mod.src
{
import flash.display.*;
import flash.text.*;


public class CustomBlitButton extends Sprite
{
    public static const OFF:int = 1;
    public static const OVER:int = 2;

    private var offBackGroundBD:BitmapData;

        this.positionOffset = positionOffset;
        this.x = x;
        this.y = y;


        offBackGroundBD = imageOff;
        overBackGroundBD = imageOver;

        buttonBackGroundBitmap = new Bitmap(offBackGroundBD);

        tempText.embedFonts = true;
        tempText.blendMode = BlendMode.LAYER;
        tempText.autoSize = TextFieldAutoSize.LEFT;
        tempText.defaultTextFormat = textformat;
        tempText.selectable = false;
        tempText.setTextFormat(textformat);
        tempText.text = text;

        buttonTextBitmapData = new BitmapData(tempText.textWidth + positionOffset, tempText.textHeight
                                              + positionOffset,true,0x00000000);

        buttonTextBitmapData.draw(tempText);
        buttonTextBitmap = new Bitmap(buttonTextBitmapData);
        buttonTextBitmap.x = ((buttonBackGroundBitmap.width - int(tempText.textWidth))/2)-positionOffset;
        buttonTextBitmap.y = ((buttonBackGroundBitmap.height - int(tempText.textHeight))/2)-positionOffset;

        addChild(buttonBackGroundBitmap);
        addChild(buttonTextBitmap);
        this.buttonMode = true;
        this.mouseChildren = false;
        this.useHandCursor = true;
    }

    public function changeBackGroundColor(typeval:int):void
    {
        if (typeval == CustomBlitButton.OFF)
        {
            buttonBackGroundBitmap.bitmapData = offBackGroundBD;
        }
        else
        {
            buttonBackGroundBitmap.bitmapData = overBackGroundBD;
        }
    }


}

}

您的代码非常混乱,但我想指出一些我发现的可能会使您的代码正常工作的小故障:

首先,在CustomScreen的单个实例中创建按钮时,它们链接到同一个变量:CustomScreen.custButton

然后,custButton是具有侦听器的按钮,而不是链接按钮的引用:creditsButton和settingsButton

因此,每次创建按钮时,都会将custButton链接到其他对象,也会链接监听器,而上一个按钮将被取消链接,并且不会侦听事件

我建议您创建一个真正的Button类,每个按钮都必须从中派生,这个“母亲”类必须实现自己的侦听器,并为您喜欢的鼠标事件分派事件

我就是这么做的:

首先,如果您想要一些订单,请创建一个按钮界面:

package buttons 
{
    import flash.events.MouseEvent;

    /**
     * ...
     * @author Joe Cabezas
     */
    public interface IButton 
    {
        function onClick(e:MouseEvent):void;
        function onRollOver(e:MouseEvent):void;
    }

}
然后,创建按钮类,其中每种按钮都必须派生自:

package buttons 
{
    import flash.display.Sprite;
    import flash.events.MouseEvent;
    /**
     * ...
     * @author Joe Cabezas
     */
    public class Button extends Sprite implements IButton
    {

        public function Button() 
        {
            this.agregarListeners();
        }

        private function agregarListeners():void 
        {
            this.addEventListener(MouseEvent.CLICK, onClick);
            this.addEventListener(MouseEvent.ROLL_OVER, onRollOver);
        }

        /* INTERFACE botones.IButton */

        public function onClick(e:MouseEvent):void
        {

        }

        public function onRollOver(e:MouseEvent) :void
        {

        }

    }

}
接下来,每当您想要创建一个按钮时,只需扩展上面的button类,它就会自动设置自己的侦听器,请参见扩展button类的MenuButton示例

package buttons
{
    import com.as3joelib.generators.TextFieldGenerator;
    import flash.display.Sprite;
    import flash.text.TextField;
    import flash.text.TextFieldAutoSize;
    import flash.text.TextFormatAlign;
    /**
     * ...
     * @author Joe Cabezas
     */
    public class BotonMenuSuperior extends Button 
    {
        //constantes de diseño
        private const padding:Number = 10;

        private var fondo:Sprite;
        private var color:uint;

        private var text_string:String
        private var text_field:TextField;

        public function BotonMenuSuperior(text:String, color:uint) 
        {
            super();

            this.text_string = text;
            this.color = color;

            this.setup();
            this.dibujar();
        }

        private function setup():void 
        {
            //crear textfield
            this.text_field = TextFieldGenerator.crearTextField(this.text_string, {
                //border:true,
                size:15,
                embedfonts:false,
                color:0xffffff
            });
            this.text_field.x = this.padding*0.75;
            this.text_field.y = this.padding*0.75;

            //crear fondo
            this.fondo = new Sprite();

            this.fondo.graphics.beginFill(this.color);
            this.fondo.graphics.drawRect(0, 0, this.text_field.textWidth + 2*this.padding, this.text_field.textHeight + 2*this.padding);
            this.fondo.graphics.endFill();
        }

        private function dibujar():void 
        {
            this.addChild(this.fondo);
            this.addChild(this.text_field);
        }


        //overriding functions to create the custom behavior of this button when mouse events happens
        override public function onClick (e:MouseEvent):void{
            //do here whatever you like when user clicks this button, like:
            this.scaleX = this.scaleY = 1.5;
        }


    }

}
正如您所看到的,这个类没有定义/创建它的侦听器,因为已经有了它,然后您可以创建自定义事件,例如使用Button类来冒泡它的事件

希望这对你有帮助

另外,在代码中还有一个提示:

public class CustomScreen extends Sprite {

    ...

    public function createButton(button:CustomBlitButton, btnOff:ButtonOff, btnOver:ButtonOver, text:String, location:Point, width:Number,
                                 height:Number, textFormat:TextFormat, positionOffset:Number = 0):void {

    custButton = button; //<-- this

    custButton = new CustomBlitButton(btnOff, btnOver, location.x, location.y, width, height, text,
                                    textFormat, positionOffset);
    addChild(custButton);

    ...
    }
}
请创建接口,它将使您的代码更加有序

再见
