Question

有人可以告诉我这件事我做错了吗？

我有一个名为炮塔的电影剪辑，它位于屏幕上并被设为Turret，我有一个名为bullet的影片剪辑，它出现在AS“bullet”没有引号的库中。

我的frame（main）类名为du34

我的du34代码是：

package

    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.MouseEvent;

        private static const SCREEN_HEIGHT: int = 1000

        private var turret: Turret = null
        private var me: MouseEvent = null
        private var trigger: Boolean = false

        private var bullets: Array = []

        public function Main():void 
        {
            graphics.beginFill(0x0)
            graphics.drawRect(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)
            graphics.endFill()

            turret = new Turret(SCREEN_WIDTH / 2, SCREEN_HEIGHT)
            turret.addEventListener(Turret.ADD_BULLET, onAddBullet)
            addChild(turret)

            addEventListener(Event.ENTER_FRAME, onEnterFrame)
            stage.addEventListener(MouseEvent.MOUSE_DOWN, function(): void { trigger = true } )

        }

        private var nextAddBullet: Bullet = null;
        private function onAddBullet(e: BulletEvent): void {
            nextAddBullet = new Bullet(turret.x + e.pos, turret.y, mouseX, mouseY)
        }

        private var frameProcessing: Boolean = false

        private function onEnterFrame(e: Event): void {

            }

            turret.frameAction(trigger)
            var i: int

                var bullet: Bullet = bullets[i]

                if (null != bullet) {
                    if (bullet.frameAction()) {
                        removeChild(bullet)
                        bullets[i] = null
                    }
                }
            }

            i = bullets.length
            while (0 < i--) {
                if (null == bullets[i]) bullets.splice(i, 1)
            }
            frameProcessing = false
        }
    }
}

我不断收到编译错误

5008：定义“Main”的名称不反映此文件的位置。请更改此文件中的定义名称，或重命名file.du34.as

Answer 1

按照错误中的建议操作。将包定义中的Main类重命名为du34（或调用任何AS3文件），或将其所在的文件重命名为Main。 The class and filename have to match：

ActionScript 3.0允许您在一个源文件中包含多个类，但每个文件中只能有一个类可用于该文件外部的代码。换句话说，每个文件中只能在包声明中声明一个类。您必须在包定义之外声明任何其他类，这使得这些类对该源文件之外的代码不可见。 在包定义中声明的类的名称必须与源文件的名称匹配。

Answer 2

你需要更多的分号吗？似乎很多分号都丢失了。也许改变班级名称可能有所帮助。

Answer 3

在正常使用的动作中，每个“as”文件需要一个类 “as”文件需要与该类命名相同类名应使用首字母ex：MyClass
命名所有类文件都需要包含在一个包中包结构需要反映导向器与源fla / mxml文件的关系在您提供的示例代码中，您有5个类，您需要5个“as”文件
以下示例假定包/类与FLA

位于同一目录中

保存为Main.as

package
{
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.MouseEvent;

    [SWF(width=1000, height=1000, framerate=24)]
    public class Main extends Sprite
    {
        private static const SCREEN_WIDTH: int = 1000
        private static const SCREEN_HEIGHT: int = 1000

        private var turret: Turret = null
        private var me: MouseEvent = null
        private var trigger: Boolean = false

        private var bullets: Array = []

        public function Main():void
        {
            graphics.beginFill(0x0)
            graphics.drawRect(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)
            graphics.endFill()

            turret = new Turret(SCREEN_WIDTH / 2, SCREEN_HEIGHT)
            turret.addEventListener(Turret.ADD_BULLET, onAddBullet)
            addChild(turret)

            addEventListener(Event.ENTER_FRAME, onEnterFrame)
            stage.addEventListener(MouseEvent.MOUSE_DOWN, function(): void { trigger = true } )
            stage.addEventListener(MouseEvent.MOUSE_UP, function(): void { trigger = false } )
        }

        private var nextAddBullet: Bullet = null;
        private function onAddBullet(e: BulletEvent): void
        {
            nextAddBullet = new Bullet(turret.x + e.pos, turret.y, mouseX, mouseY)
        }

        private var frameProcessing: Boolean = false

        private function onEnterFrame(e: Event): void
        {
            if (frameProcessing) return
            frameProcessing = true

            if (null != nextAddBullet) {
                bullets.push(nextAddBullet)
                addChild(nextAddBullet)
                nextAddBullet = null
            }

            turret.frameAction(trigger)
            var i: int
            for (i = 0; i < bullets.length; i++) {
                var bullet: Bullet = bullets[i]

                if (null != bullet) {
                    if (bullet.frameAction()) {
                        removeChild(bullet)
                        bullets[i] = null
                    }
                }
            }

            i = bullets.length
            while (0 < i--) {
                if (null == bullets[i]) bullets.splice(i, 1)
            }
            frameProcessing = false
        }
    }
}

你还需要BulletEvent，Bullet，Barrel，Turret的“as”文件

Answer 4

试试这个..将包定义中的Main类重命名为du34。在目录中（与.fla相同的位置）创建文件夹名称du34并将du34.as放入其中。

ActionScript编译错误：定义“Main”的名称不反映此文件的位置
