Question

我有一个增强现实移动应用程序，其中声音会自动为特定的图像目标播放，当目标丢失时声音会停止。我需要的是如何在仍然聚焦于该图像目标的同时，通过使用按钮来重复声音。

示例：

          Image target - Apple 
          Sound - Letter A sound

         Image target- Banana
         Sound - Letter B sound

当我专注于苹果的图像目标时，会发出字母A的声音。我该如何使用按钮来重复这种声音，这样我就不必再次专注于图像目标了。

有多种方法可以做到这一点

通常，您将拥有一个带有公共方法的组件，例如

<?php
    $first = ( $per_page * $paged ) - $per_page;
    $last  = min( $total, $per_page * $paged );
    $current = isset( $paged ) ? $paged : wc_get_loop_prop( 'current_page' );
    $base    = isset( $base ) ? '' : esc_url_raw( str_replace( 999999999, '%#%', remove_query_arg( 'add-to-cart', get_pagenum_link( 999999999, false ) ) ) );
    $format  = isset( $format ) ? '?page=%#%' : '%#%';

            echo paginate_links( apply_filters( 'woocommerce_pagination_args', array( // WPCS: XSS ok.
                'base'         => $base,
                'format'       => $format,
                'add_args'     => false,
                'current'      => max( 1, $current ),
                'total'        => ceil($total / $per_page),
                'prev_text'    => '&larr;',
                'next_text'    => '&rarr;',
                'type'         => 'list',
                'end_size'     => 3,
                'mid_size'     => 3,
            ) ) );

        ?>

将其放在public class SoundController : MonoBehaviour { // here you reference your Scene's AudioSource in the inspector // e.g. via drag and drop [SerializeField] private AudioSource _audioSource; // Here you reference the according AudioClips [SerializeField] private AudioClip _letterASound; [SerializeField] private AudioClip _letterBSound; // an enum makes it esier to find the correct letter later public enum Letter { A, B // etc } // store the current Sound to be played public Letter CurrentLetter; private Button _button; // a dictionary makes it easy to find the according sound for a specific letter private Dictionary<Letter, AudioClip> _sounds; private void Awake() { // initialize the dictionary _sounds = new Dictionary<Letter, AudioClip>() { {A, _lettarASound}, {B, _letterBSound} } // get the Button component _button = GetComponent<Button>(); // add an onclick callback for the button // (it is save to allways first remove the callback to avoid double calls) _button.onClick.RemoveListener(PlayCurrentSound); _button.onClick.AddListener(PlayCurrentSound); } // make it public so you could even call it from somewhere else if needed public void PlayCurrentSound() { AudioSource.PlayOneShot(_sounds[CurrentLetter]); } }组件旁边的按钮上，并引用Button和AudioSource（当然，可以根据需要添加更多内容）。

现在，剩下的就是每次将鼠标悬停在新的字母上时都更改AudioClip。我不知道您的代码看起来如何，但是您会添加类似的内容

CurrentLetter

因此，下次您按下按钮时，它将播放A的声音。

当目标发现我需要的是如何重复该声音时，增强现实对象就会发出声音
