Beginners to Unity might imagine that you develop your game from start to finish in Unity, including writing code, creating 3D models and textures, and so on .
    初学者总是想象着整个游戏的开发过程都能基于Unity3D引擎来实现,包括代码编写,三维模型创建,特征创建等。
    In reality, a better way of thinking about Unity is as an integration tool. Typically you will write code or create 3D models or textures in a separate program, and use Unity to wire everything together.
    在现实中,最好是将Unity看成是一个集成工具。编写代码,创建三维模型及特征最好是基于其它的独立软件,然后再使用Unity将其集成在一起。
