1.5 发现unity的资源内容
1.5 Discovering Unity's content
As you enter Unity for the first time, you might think you'll need to build and code everything from scratch. However, Unity comes with several collections of content called Packages, designed to save you time when implementing commonly required features.
正如你第一次进入Unity里时，你也许会想你要用你的胡逼操作创建、编写每一个东西。然而，实际上，unity本身自带了几种收集好的内容，被称之为“Packages”（包），当仅仅执行一般性指令的时候，可以来拯救你。
How to do it...（如何去做）
Let's find out what's inside Unity's standard packages:
让我们找出有哪些标准包在unity里面吧：
1.Inside the Unity editor, access the Assets menu.
1.在unity编辑器中，打开Assets菜单。
2.Expand the Import Package submenu.
2.打开Import Package（导入包）分选项。
3.You will see a list of available packages from Unity. These are filled with ready-to-use content.
3.你会看到一个可使用包的一个列表，这里都是预使用的资源内容。
How it works...（工作原理）
Unity makes implementing commonly requested features easy by making them available as packages ready to be imported and used in your project. These packages include First-Person and Third-Person Character Controllers, Image Effects (Pro Only), Terrain textures and assets,Skyboxes, Water, Tree Creator, and more.
Unity把一些常用的功能和内容以打包的形式储存起来，让你在把他们导入到项目里之后，可以更加轻松的使用。这些包，包括第一人称和第三人称角色控制器、图像特效（只有专业版有）、地形纹理以及天空盒、流水、树木创建器等等。
There's more...（更多）
There are other ways to learn from ready-made material. Here are some:
你可以从已有的资源中学习，比如：
Studying the sample project
学习样本项目
Unity also comes with a sample project ready to be dissected by you. It automatically opens the first time you start the software.
Unity在你安装时会自带一个样本项目，在你第一次使用软件的时候会自动打开（5以后需要手动寻找，有的没有案例项目的是因为在安装的时候你没有勾选样本项目资源下载，你可以上网寻找资源下载）。
