代码复用和合并
在换装原理初探中介绍了换装的核心步骤，但是只有一种男孩角色的换装，本文考虑男孩和女孩的换装。并且，对上文的一些变量命名进行调整，Target均改为Avatar，合并Model和Avatar的加载方法。其实考虑男孩和女孩的换装，主要是代码的复用和合并问题。
- 加载Model和Avatar。由于需要复用代码，因此需要在加载方法中给出参数，这里主要有模型名字modelName，avatarName，加载存储到的变量modelTrans和avatarTrans。
- 保存数据。同样，需要有参数，变量modelTrans和avatarTrans，参数保存容器modelData、avatarData和hips。
- 换装。参数容器modelData、avatarData和hips，变换部位名字partName和变换型号num。
测试
为了完成上述代码的测试工作，需要定义一些测试单元，新增一个Gender变量表示男孩或女孩。
- 在Start函数中，完成初始化测试。
- 在Update函数中，分别完成性别切换测试和换装测试。性别切换点击鼠标左键完成，换装点击鼠标右键完成。
