近期发现关于Unity实现音乐播放器的资源较少,我来放一波!

介绍

首先,这个功能的实现仅为demo,给予正在实现本功能的小伙伴一点思路.如果帮到了一些人也属初心所向,不喜勿喷!

工程源码::Demo源码工程

逻辑

主要依赖于UGUI Scroll View通过调用它的verticalNormalizedPosition属性来实现轮播滚动的效果.

歌词的存储格式常见的为**.lrc文件,通过IO将每一行读取到一个List**里,再由循环将每段歌词实例化在Scroll View 的 Content节点下.

场景搭建

创建一个Scene场景 :VideoScene

创建一个Scroll View 如图:

在父物体 Canvas层 挂载一个 Audio Source 同时把我们想要播放的歌曲文件拖到 AudioCilp这个属性里

配置 Content节点的组件

代码部分

可以创建一个脚本 命名 AudioTest.cs
