音频进入Phaser？

Question

我正在设计一个游戏，玩家将得到4种声音，他们必须猜测声音有什么共同之处。它的工作原理是"4图片1字“游戏，但不是图片，玩家必须猜出声音。

用户必须按1、2、3和4键才能听到声音。一旦玩家听到了声音，玩家就必须猜出这些声音有什么共同之处。我如何编码的部分，在玩家听到了4的声音后，他们会输入这个词来猜测它？

作为第1级的一个例子，玩家将被给予猫，狗，鹦鹉和仓鼠的声音，并且必须猜测这四种声音之间的共同之处。玩家在听到声音后会被通知，这个单词由3个字母组成，他们必须猜出它是什么。如果玩家插入字母"E“，则"E”将被插入到缺失的单词中，而玩家需要猜测剩下的单词。正确的词将是"PET“。我怎么用Phaser编码这个？

(顺便说一句，这款游戏没有图形或动画，因为它是为盲人用户准备的)。

我收到错误消息"Uncaught :意外令牌{“一行"if SyntaxError {”。

在听到这四种声音后，我仍在尝试播放的输入不起作用。我不知道我哪里出了问题。

我的代码：

  var game = new Phaser.Game(400,490, Phaser.AUTO, 'gameDiv');
  var key1;
  var key2;
  var key3;
  var key4;
  var speech;
  var level1;
  var PCorrect;
  var ECorrect;
  var TCorrect;
  var TryAgain;
  var mainState = {


preload: function() {
    game.stage.backgroundColor ='#71c5cf'
    game.load.audio('the_intro', 'assets/speech_intro.wav');
    game.load.audio('start', 'assets/cat_meow.wav');
    game.load.audio('second', 'assets/dog_bark.wav');
    game.load.audio('third', 'assets/mouse_squeak.wav');
    game.load.audio('fourth', 'assets/parrot.wav');

    //Call the sound when the key is pressed
    var self = this;
    game.input.keyboard.onDownCallback = function(e) {
        var keycode = e.keycode || e.which;

        switch(keycode) {

            case Phaser.Keyboard.ONE:
                 self.addCat();

我建议你不要听特定的键，而是所有的键。您可以使用Keyboard.addCallbacks方法来完成这一任务。签名如下：

/** * Add callbacks to the Keyboard handler so that each time a key is pressed down or released the callbacks are activated. * * @method Phaser.Keyboard#addCallbacks * @param {Object} context - The context under which the callbacks are run. * @param {function} [onDown=null] - This callback is invoked every time a key is pressed down. * @param {function} [onUp=null] - This callback is invoked every time a key is released. * @param {function} [onPress=null] - This callback is invoked every time the onkeypress event is raised. */ addCallbacks: function (context, onDown, onUp, onPress) {

您只需了解onPress事件，就可以：

game.input.keyboard.addCallbacks(this, null, null, keyPress);

其中keyPress是按下键时调用的函数的名称。此函数将被发送到按下为字符串的字符。因此，在这个函数中，如果您正在寻找来自播放器的PET单词，您可以检查按下的键是P、E还是T，并相应地突出显示它。下面是我为您提供的一个工作示例：http://examples.phaser.io/debug.php?f=input/word+input.js
