AudioSource.Play

# [AudioSource](https://docs.unity3d.com/cn/2019.4/ScriptReference/AudioSource.html).Play

public void **Play** (ulong **delay**= 0);

## 参数

| delay | 已弃用。以样本数为单位的延时，假设采样率为 44100Hz（意味着 Play(44100) 将使播放延时整整 1 秒）。 |
| ------- | -------------------------------------------------------------------------------------------------- |

## 描述

播放 [clip](https://docs.unity3d.com/cn/2019.4/ScriptReference/AudioSource-clip.html)。

该 delay 参数已弃用，请改用更新的 PlayDelayed 函数指定延时（以秒为单位）。

如果 [AudioSource.clip](https://docs.unity3d.com/cn/2019.4/ScriptReference/AudioSource-clip.html) 设置为正在播放的同一剪辑， 则该剪辑听起来将像是重新开始播放一样。[AudioSource](https://docs.unity3d.com/cn/2019.4/ScriptReference/AudioSource.html) 假设 所有 [Play](https://docs.unity3d.com/cn/2019.4/ScriptReference/AudioSource.Play.html) 调用将播放新的音频剪辑。

__注意：[__AudioSource.PlayScheduled](https://docs.unity3d.com/cn/2019.4/ScriptReference/__AudioSource.PlayScheduled.html) API 可以让您更准确地控制播放音频剪辑的时间。
