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...

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。 我们首先要确定使用哪种CastType,然后才能决议使用哪个版本的特化TCastImpl。

Unreal Engine C++ 为反射系统提供了内置支持,该系统提供了执行类型安全向上和向下转换的方式,而无需 dynamic_cast<T*>。 让我们看看函数 Cast: template <typename To, typename From> FORCEINLINE To* Cast(From* Src) { return TCastImpl<From, To>::DoCast(Src); ...
If you wish to encrypt the created files, you could provide an AES key, but I am pretty sure Unreal Engine won't be able to decrypt your files. I just added this encryption "feature" for experimentation. int packGameFiles(char *dirPath, char *manifestPath, char *outFile, char *...
