预制件原来自动生成的啊。。

Live2D的使用
Live2D导入Unity后文件结构如下，并且官方也提供了多个演示场景以供大家学习使用。
基本功能和使用。
导入前的Live2D文件结构如下：
分别为表情的Json配置文件，动作的Json配置文件，贴图以及物理Json配置文件等。
将此导入Unity后Live2D会自动处理配置文件，并在Runtime文件夹下生成Liv2D的预制体，expressionList表情列表和fadeMotionList动作列表，列表的引用关系Live2D已自动处理。
Live2D预制体所挂脚本：
可选功能脚本：
LookController与LookTarget配合使用，控制Live2D的鼠标追踪效果。
Mouth，EyeBlink控制Live2D自动眨眼功能和嘴巴张闭。
Expression表情管理。
Fade 动作淡入淡出管理。
同时自动眨眼还有鼠标追踪等功能，需要在相应可动部位添加相应功能脚本。
如自动眨眼：
嘴巴：
鼠标追踪：
这些都是Live2D提供的基本功能，只需要挂载相应脚本便可实现功能。
动作和表情的播放

注意，可交互部位要挂载相应功能脚本，点击才会生效。如要点击身体部位，可在预制体的Drawables下将相关区域挂载CubismHitDrawable与CubismRaycastable脚本。如：
如此，射线检测到点击的相应区域，便可播放相应的动作或者表情了。
