需要帮助让按钮在 Adob​​e Flash 中播放多种声音

Question

我在尝试让我的代码为我的 Adob​​e Flash 项目工作时遇到问题。基本上，我试图让一个按钮在每次单击它时播放随机声音，这很有效，但我不能在同一帧上为不同的按钮使用相同的代码，这就是它给我这个错误的原因。

这是我的代码：

    import flash.utils.Dictionary;
import flash.events.MouseEvent;

var request:URLRequest = new URLRequest("19103_b.mp3");
var ci_diese:Sound = new Sound();
ci_diese.load(request);

var request_two:URLRequest = new URLRequest("19203_b.mp3");
var d_diese:Sound = new Sound();
d_diese.load(request_two);

var request_three:URLRequest = new URLRequest("19204_b.mp3");
var f_diese:Sound = new Sound();
f_diese.load(request_three);

var play_liste = 0;

var dictSounds = new Dictionary ();

dictSounds[1] = d_diese;
dictSounds[2] = ci_diese;
dictSounds[3] = f_diese;

fireweapon_H3AR.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler);

function mouseDownHandler (event:MouseEvent) : void {
    play_liste = Math.ceil(Math.random () *3); 
    dictSounds[play_liste].play ();

ready_H3AR.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler);

function mouseDownHandler (event:MouseEvent) : void {
    play_liste = Math.ceil(Math.random () *3); 
    dictSounds[play_liste].play ();}
}
import flash.utils.Dictionary;
import flash.events.MouseEvent;

var request:URLRequest = new URLRequest("Readya.mp3");
var ci_diese2:Sound = new Sound();
ci_diese2.load(request);

var request_two:URLRequest = new URLRequest("Readyb.mp3");
var d_diese2:Sound = new Sound();
d_diese2.load(request_two);

var request_three:URLRequest = new URLRequest("Readyc.mp3");
var f_diese2:Sound = new Sound();
f_diese2.load(request_three);

var play_liste = 0;

var dictSounds = new Dictionary ();

dictSounds[1] = d_diese2;
dictSounds[2] = ci_diese2;
dictSounds[3] = f_diese2;

ready_H3AR.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler);

function mouseDownHandler (event:MouseEvent) : void {
    play_liste = Math.ceil(Math.random () *3); 
    dictSounds[play_liste].play ();}
}

有什么方法可以重写它以容纳多个按钮？前半部分一直持续到它在“导入闪存”处重复。我一直在到处寻找答案，所以请帮忙！

Answer 1

您不应将两个函数或两个变量命名为相同，因为最后一个会覆盖第一个。

例如

var request:URLRequest = new URLRequest("19103_b.mp3");

然后被覆盖

var request:URLRequest = new URLRequest("Readya.mp3");

按钮 ready_H3AR 和函数监听器 mouseDownHandler 也会发生同样的情况

顺便说一句，你不需要两次导入类：

import flash.utils.Dictionary;
import flash.events.MouseEvent;

通常当一个任务或一段代码打算被多次使用时，最好把它放在一个函数中，以获得更简单和更易于维护的代码。

所以你可以这样做：

var sounds:Array = [
    ['01.mp3', '02.mp3', '03.mp3'],     // sounds for the 1st button
    ['04.mp3', '05.mp3', '06.mp3']      // sounds for the 2nd button
];

var sound:Sound,
    sound_channel:SoundChannel = new SoundChannel();

function play_sound(sound_name:String): void 
{
    var request:URLRequest = new URLRequest('mp3/' + sound_name);   
    sound = new Sound();
    sound.addEventListener(Event.COMPLETE, on_sound_loaded); 
    sound.load(request); 
}
function on_sound_loaded(e:Event): void 
{ 
    // if you want, you can stop the current playing sound 
    // otherwise you don't need the SoundChannel
    sound_channel.stop();
    sound_channel = Sound(e.target).play(); 
}

button_01.addEventListener(MouseEvent.MOUSE_DOWN, on_press);
button_02.addEventListener(MouseEvent.MOUSE_DOWN, on_press);
function on_press(e:MouseEvent): void
{
    // to get values : 0, 1 or 2
    var random:int = int(Math.random () * sounds[0].length);
    // if it's the 1st button so pick the sound from the 1st sounds array
    if(e.currentTarget.name == 'button_01'){
        play_sound(sounds[0][random]);
    } else {
        play_sound(sounds[1][random]);
    }
}

希望能有所帮助。
