AudioSource.loop

描述

是否循环播放该音频剪辑？

返回或设置在完成某音频剪辑的播放后是否重放该音频剪辑。 如果对正在播放的 AudioSource 禁用循环播放，则在当前循环结束后停止播放该声音。AudioSource 组件中有一个复选框，让您能够在不编写代码的情况下启用或禁用循环播放。

//Create an empty GameObject and attach this script
//Attach an AudioSource component. (Click on the GameObject, go to its Inspector and click Add Component Button. Go to Audio>Audio Source)
//Attach an Audio clip in the AudioClip field of the AudioSource
//Create a Button (Create>UI>Button) and a Toggle (Create>UI>Toggle). Attach these in the Inspector of your GameObject.

//This script allows you to toggle the loop of a sound on or off
