c++11中常见的智能指针有三种: unique_ptr、 shared_ptr、weak_ptr 对于智能指针的具体使用可以参考下边的网址:A beginner's look at smart pointers in modern C++ Unreal Engine也实现了自己的一套智能指针,具体详细参考虚幻智能指针库 std::shared_ptr不是在所有的平台都能用的。 可以和其它虚幻容器及类型无缝...
シェアード ポインタは Unreal オブジェクト (UObject およびその派生クラス) と互換性がありません。Unreal Engine には UObject 管理のための独自のメモリ管理システムがあります (「Unreal でのオブジェクトの処理」 を参照)。これら 2 つのシステムは互いに干渉しません。 ...

Smart pointersare not intended to be used with UObjects. Strong references keep UObjects alive. IsValid()is for checking if it's null or garbage, but most usages of IsValid can be replaced with proper programming conventions like clearing pointers to Actors when they have theirOnDestroyevent ...
Even more technical, on Smart Pointers in Unreal Class Default Object Class Default Objectis the default instance of a class in Unreal Engine. This instance is automatically created and used to quickly instantiate new instances. You can use this CDO in other ways too to avoid having to manually...
Smart pointersare not intended to be used with UObjects. Object->MarkPendingKill()has been replaced withObj->MarkAsGarbage(). This new function is now only for tracking stale objects, Ifgc.PendingKillEnabled=truethen objects marked asPendingKillwill be automatically nulled and destroyed by Garbag...
5. Unreal Smart Pointer Library The Unreal Smart Pointer Library is a custom implementation of C++11 smart pointers designed to ease the burden of memory allocation and tracking.These classes cannot be used with the UObject system because Unreal Objects use a separate memory-tracking ...

Using shared pointers allows you to assume ownership of these slate widgets without having to call delete on them. I recommend taking a look at Epic's Documentation on Smart Pointers An important note that when casting Slate Widget's it is totally fine to use standard casting such as static...
A reference cycle exists whenever two or more objects use Smart Pointers to keep strong references to each other. In these situations, the objects protect each other from deletion, as each one is always being referenced by one other object, and so neither can be deleted while the other still...
