歌曲采摘系统

Question

我正在尝试在我的项目中选择一首歌。每次你点击游戏中的一个按钮，它就会发送int给这个函数。有没有更好的方法来构建这个代码，所以我不必为每首歌编写IF语句？

public void SongPick(int song)
{
    if (song == 0)
    {
        audioSource.clip = musicArray[0];    
    }
    if (song == 1)
    {
        audioSource.clip = musicArray[1];
    }
    if (song == 2)
    {
        audioSource.clip = musicArray[2];
    }

    audioSource.Play();
    string currentMusic = musicArray[song].name;
    songName.text = "PLAYING: " + currentMusic;
}

Answer 1

假设song始终引用musicArray中的正确索引，您绝对不需要一个不断增长的if语句。

public void SongPick(int song) {
    if (song < musicArray.length) {
        audioSource.clip = musicArray[song];    
    }    
    audioSource.Play();
    string currentMusic = musicArray[song].name;
    songName.text = "PLAYING: " + currentMusic;
}
