现在公司的游戏虽然也实现了换装，但是存在一定的问题。我们项目中的换装系统的实现是这样的：一套没有蒙皮信息的人物空骨骼模型（虚拟体），头、身体、武器是独立于人物骨骼的具有蒙皮信息的模型。换装时将模型置为“T-pos”状态，删除需要身体上对应的meshpart, 然后将新的模块模型拷贝到角色骨骼下面，将蒙皮所依赖的骨骼根据名称拷贝到人物模型对应的骨骼下面。这样虽然也实现了换装，但却在人物骨骼中多添加了许多骨骼，造成资源的浪费，而且每次换装都会使模型动画置到默认状态下。
一直想完善现在项目的化妆系统，这个周末终于有时间了，于是利用周天重写了一个简单的换装系统，以此验证一下我设想的换装是否可行。如果可行，便整合到目前的项目中。
其实原理很简单，提取换装模型的蒙皮信息，在人物骨骼中按照提取出来的蒙皮信息重新实现一遍。
说了一大堆废话，还是直接上代码吧：
