1. 通过设置两个蓝图的变量，并通过CreateUIWidget保存获取相应的UI界面，这样另一个蓝图就可以获取对象，从而通过变量进行沟通2. 通过命令行Execute Console Command3. 通过Event Dispatchers进行绑定时间，并在触发的地方Call。 注意：绑定bind的事件已经要运行到节点才能绑定上。例子中使用了在初始化的时候就进行了绑定

派生自 Actor 的类前缀为 A，如 AController。派生自 对象 的类前缀为 U，如 UComponent。枚举 的前缀为 E，如 EFortificationType。接口 类的前缀通常为 I，如 IAbilitySystemInterface。模板 类的前缀为 T，如 TArray。派生自 SWidget（Slate UI）的类前缀为 S，如 SButton。

Actor 相当于 Unity中的GameobjectPawn相当于带了控制器或者被AI控制的继承与Actor的类。
