I am reading the UE5 migration guide (Unreal Engine 5 Migration Guide | Unreal Engine 5.0 Documentation), and I see that TObjectPtr is now recommended over . So to answer you. What is it: TemplateClass wrapper around raw c++ pointers. What does it do: Mentioned above. Why should anyone use it: Lazy-loading .Help shape the future of Unreal Engine documentation!

My friend introduced me to TStrongObjectPtr, which appears to be a shared pointer for UObjects. This might provide what we want. docs.unrealengine.com . Place the created UObject into UPROPERTY/TStrongObjectPtr# If you’re confident about the background thread’s lifespan tied to the parent UObject’s existence, .© 2004-2024, Epic Games, Inc.

Unreal Engine 5 C++ Guide - TObjectPtr.In this video i am going to introduce the new Unreal Engine 5 TObjectPtr template-based 64-bit pointer system, that is. I am reading the UE5 migration guide (Unreal Engine 5 Migration Guide | Unreal Engine 5.0 Documentation), and I see that TObjectPtr is now recommended over raw pointers. But the only thing the guide says about what this new type does is this: This system adds dynamic resolution and access tracking in editor builds What exactly does .

Или использовать его готовую реализацию под один объект -TStrongObjectPtr<>. При вызове деструктора FGCObject жесткая ссылка удалится и объект будет передан на удаление, если их не осталось.对一个指针的不同解析. 如上图所见，TObjectPtr内部是一个FObjectHandle，然后FObjectHandle本质就是一个指针，epic自己也说SHIPPING下就如同UE4一样，就是一个UObject指针。. 接下来看一下，为什么有TObjectPtr这一出吧。. 其实是由于UE5抛弃了32位系统，那么整个指针就有64bit .
使用智能指针TStrongObjectPtr，TStrongObjectPtr内部会有一个继承FGCObject的对象，然后这个对象会持有这个UObject，原理和第2点差不多。只要指针不被销毁，对象就不会被回收。 手动回收对象. 我们可以调用UObjectBaseUtility::MarkAsGarbage()，下一次GC就会回收这个对象。TStrongObjectPtr：不推荐使用。引用的对象，强制不会被GC; FSoftObjectPath：不推荐使用。由上面的指针类型在内部使用，很慢，因为它不缓存结果; FSoftClassPath：不推荐使用。与 FSoftObjectPath 相同，但有一些与加载类相关的辅助函数Help shape the future of Unreal Engine documentation!

The IsValid method should be used to check for validity. The Pin method can be used to get a shared pointer to the target object.

Unreal’s own build tool is the creatively-named UnrealBuildTool (UBT), which makes heavy use of the UnrealHeaderTool (UHT) for code generation. Your actual build files are the Target.cs and Build.cs files you get when you create any starter C++ project template or add a C++ class to a BP-only project.Specific implementation of [FGCObject](API\\Runtime\\CoreUObject\\UObject\\FGCObject) that prevents a single UObject-based pointer from being GC'd while this guard is in scope.Help shape the future of Unreal Engine documentation!
