本文介绍了一个用于Unity游戏开发中的特效预加载系统实现方案。该系统通过读取XML配置文件来加载不同角色所需的特效资源，并支持场景特效及UI提示的预加载。文中详细展示了代码逻辑与配置文件结构。

目录为：Assets/Scripts/ConfigReader/目录下
ReadPreLoadConfig.cs

这个文件专门预加载特效的

对应配置文件：
Assets/Resources/Config/PreLoad.xml
部分如下

<PreloadEffect>
    <Roles>
        <Role id ="10001">
            <Effect>effect/skill/release/sakuraline</Effect>
            <Effect>effect/skill/buff/chenmo</Effect>
            <Effect>effect/skill/release/sakuraline_ex</Effect>
            <Effect>effect/skill/buff/sakuraarea</Effect>
            <Effect>effect/skill/buff/Prohibited_weapon</Effect>
            <Effect>effect/skill/buff/sakuraarea_ex</Effect>
            <Effect>effect/skill/hit/Hitsakura</Effect>
            <Effect>effect/skill/hit/Hitsakura</Effect>
        </Role>         
        <Role id ="10002">
            <Effect>effect/skill/release/sword</Effect>
            <Effect>effect/skill/buff/stun</Effect>
            <Effect>effect/skill/release/sword_ex</Effect>
            <Effect>effect/skill/release/landcut</Effect>
            <Effect>effect/skill/buff/jiansu_buff</Effect>
            <Effect>effect/skill/release/landcut_ex</Effect>
            <Effect>effect/skill/hit/Hitcutlight</Effect>
            <Effect>effect/skill/hit/Hitblood</Effect>
            <Effect>effect/skill/hit/Hitliedizhan</Effect>
        </Role>
