Question

我对actionscript 3有疑问

我在VPAID做表演。我无法创建方法adVolume。我有编译错误

1067：将SoundTransform类型的值隐式强制转换为不相关的类型flash.media:SoundTransform。

1119：通过静态类型SoundTransform的引用访问可能未定义的属性卷。

这是一个功能adVolume

        _data = data;
    }

    public function get data():Object {
        return _data;
    }
}

}

请帮帮我

Answer 1

首先要尝试的是实例化变量＆＃39; adSoundTransform＆＃39;在做任何事情之前。编写的代码，您引用的是类，而不是类的实例。

    adSoundTransform = new SoundTransform();
    adSoundTransform.volume = value;
    ...

Answer 2

另一件事是你应该解释来自VPAID的音量，例如：从＆＃34;设置adVolume＆＃34;传递它到你的FakeAd课程。广告不应该设置自己的音量，因为播放器应该处于控制之中。

带有动作脚本VPAID的SoundTransform
