1.對MicroPhone類的理解

  對麥克風的呼叫在Unity裡主要是用到了MicroPhone這個類，此類裡面有幾個方法可以方便我們實現功能

2.程式碼演示

//此指令碼須掛在錄音按鈕上
public class Record : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
{
    float tirecordingTimemer = 0;//錄音時長限制
    public AudioSource aud;//儲存聲音
    public Text ShowTimeHint;//剩餘時間的文字提示
    public void OnPointerDown(PointerEventData eventData)
    {
        Debug.Log("Start");
        StartCoroutine("KeepTime");
        aud.clip = Microphone.Start("Built-in Microphone", false, 60, 44100);
    }
    public void OnPointerUp(PointerEventData eventData)
    {
        Microphone.End("Built-in Microphone");
        StopCoroutine("KeepTime");
        Debug.Log("Over");
        aud.Play();
    }
    //此處開攜程也行，用while也可以，放在updata裡也沒問題
    IEnumerator KeepTime()
    {
        for (tirecordingTimemer = 10; tirecordingTimemer >= 0; tirecordingTimemer -= Time.deltaTime)
        {
            if (tirecordingTimemer <= 10)
            {
                ShowTimeHint.text = "你還可以錄 " + (int)tirecordingTimemer + " 秒";
                if (tirecordingTimemer < 1)
                {
                    ShowTimeHint.text = "時間到";
                    Microphone.End("Built-in Microphone");
                }
            }
            yield return 0;
        }
    }
}
 

對應的ui元件掛靠一下直接執行工程就好了

3.執行結果

具體接下來想實現什麼功能就可以自己更改自定義
