Unity實(shí)現(xiàn)高效的音效管理類的示例代碼

更新時(shí)間：2023年03月22日 10:28:47 作者：極客柒

這篇文章主要為大家詳細(xì)介紹了如何通過(guò)Unity實(shí)現(xiàn)高效的音效管理類，文中的示例代碼講解詳細(xì)，具有一定的借鑒價(jià)值，感興趣的可以了解一下

效果

自動(dòng)維護(hù)一個(gè) AudioSource的池子

如果超過(guò)了池子的峰值池子會(huì)生成一個(gè)新的AudioSource對(duì)象來(lái)進(jìn)行擴(kuò)容

支持2D音效調(diào)用方式 public void PlaySound( string url, float volume = 1.0f, bool loop = false )
支持2D音樂(lè)調(diào)用方式 public void PlayMusic( string url, float volume = 1.0f, bool loop = true )
支持3D音效調(diào)用方式 public void PlaySoundAtPoint( string url, Vector3 position, float volume = 1f )

食用方式

更改這塊的加載用你們自己框架里的加載方式或者走 Resource.Load

源碼
