在Unreal Engine（UE）中，Cast方法用于安全地进行动态类型转换，确保目标指针指向有效且完整的对象。这在使用继承自SceneComponent的类作为Actor的RootComponent时尤为重要。转换方法的语法大致如下：当需要调用RootComponent的特定子类方法时，通过调用Cast进行转换。初看Cast将父类指针转换为子类指针似乎风险较高...
U::UClassType::StaticClassFlags & CLASS_Interface 对应的就是第三条,任何接口点击它的 #include "xxxxxx.generated.h",内查看 DECLARE_CLASS 这条宏,就看到它有添加 CLASS_Interface 类型标签。回溯到 CodeSnippet.3 五个参数我们现在能确定四个 From、To、bFromInterface、bToInterface,还差一个CastClass ...
enum class ECastType { UObjectToUObject, InterfaceToUObject, UObjectToInterface, InterfaceToInterface, FromCastFlags }; 可见主要分为UObject,Interface, FromCastFlags三类,前两者比较好理解,FromCastFlags表示使用预置的CastFlags比较是否可转型,只要位操作即可,速度最快。
