C5：Unity3D制作智能家居设计软件——新手引导系统
为什么叫新手引导系统而不叫新手引导页呢？
新手引导系统适用于各个引导环节，引导环节需要特定状态给出特定引导流程。
其出现和消失的引导页应该是可量化可控的。
话不多说，我们直接看代码：
首先，新手引导页基础类：GuidanceData

新手引导系统逻辑控制脚本：GuidanceManager

public void DestoryThis()

}
}
在场景里使用的时候，只需要调用控制脚本中的GuidanceManager方法，把父级物体赋值进去即可。
当然，缺少不了预制体，需要提前将预制体Prefabs创建，我们的预制体是一个Canvas，将其放置在Resources文件夹中便于创建，
两个脚本挂载在预制体上，结构如下：
Canvas里结构和效果如下：
具体实现，大家可以拷贝代码到自己工程里实现一下，就不多赘述了。
