还有：LoadSND 类

package 
import flash.events.*;
import flash.media.*;
import flash.net.URLRequest;
import flash.display.MovieClip;


public class LoadSND extends MovieClip 

    //declare variables
    private var sndTrack: Sound;
    private var sndChannel: SoundChannel;
    private var sndVolume: Number;
    private var newTrack: String;
    private var canRepeat: Boolean;

    public function LoadSND(myTrack: String, myRepeat: Boolean = true) 
        // constructor code
        // set a default volume and track 
        sndVolume = 0.5;
        setTrackData(myTrack, myRepeat);
    


    private function loadSound(): void 
        // first stop all old sounds playing 
        SoundMixer.stopAll();
        // create a new sound for the track and a new sound channel 
        sndTrack = new Sound();
        sndChannel = new SoundChannel();
        // load the required sound
        sndTrack.load(new URLRequest(newTrack));
        // when loaded – play it;
        sndTrack.addEventListener(Event.COMPLETE, soundLoaded);
    

    private function soundLoaded(evt: Event): void 
        // finished with this listener so remove it 
        //sndTrack.removeEventListener(Event.COMPLETE, soundLoaded);
        // call the play sound function 
        playSound();

    

    private function playSound(): void 
        // assign music to the musicChannel and play it 
        sndChannel = sndTrack.play();
        // setting the volume control property to the sound channel 
        sndChannel.soundTransform = new SoundTransform(sndVolume, 0);
        // but add this one to make repeats 
        sndChannel.addEventListener(Event.SOUND_COMPLETE, playAgain);
    

    private function playAgain(evt: Event): void 
        // remove this listener and repeat playSound() 
        sndChannel.removeEventListener(Event.SOUND_COMPLETE, playAgain);
        playSound();
    

    private function setTrackData(myTrack: String, myRepeat: Boolean): void 
        // update the new track information 
        newTrack = myTrack;
        canRepeat = myRepeat;
        // and load it 
        loadSound();

    

    private function setVolumeLevel(myVolume: Number): void 
        // change the volume when slider changed 
        sndVolume = myVolume;
        sndChannel.soundTransform = new SoundTransform(sndVolume, 0);
    




 //end class

 //end package

感谢所有帮助 :) 谢谢

【参考方案1】：

LoadSND 类中的 setTrackData 函数是私有的。您需要将函数的类型更改为公共，以便您可以从主类访问此函数。

所以像这样改变你的功能

public function setTrackData(myTrack: String, myRepeat: Boolean): void 
        // update the new track information 
        newTrack = myTrack;
        canRepeat = myRepeat;
        // and load it 
        loadSound();
