I didn't make it very clear in my answer, but the ClassToFind needs to be populated somehow (for example by exposing it to blueprints as property and setting it there).. Iterators are one of the four pillars of the Standard Template Library or STL in C++. For example if you need to scale an object from one size to another you can use FMath::Lerp to accomplish this. For any element you need localized add the data-l10n-id attribute and pass the namespace and key of the translated FText e.g. Creating the C++ world objects.

Hi there, in my current project I need a way to in C++ either a) find all classes inheriting from a certain C++ base class (including all Blueprint-generated classes) or b) find a class by its name (again, including Blueprint-generatec classes) I've tried a lot of things but couldn't get anything to work in a standalone game (some things worked in the editor, but not in the game).

CS378 UNREAL ENGINE 2 AND 3 Unreal Engine 2 development began in 1999 First game released in 2002 Improved rendering, and tools pipeline Additional features included physics, particle systems, cinematic editing systems, character animation systems Unreal Engine 3 development started in 2002 First games released in 2006 Engine added support for programmable shader pipeline, and improved looking at UCheatManager::DestroyPawns() would've made it perfectly clear how to obtain a pointer to the actor from the iterator. To get the Actor's coordinates in a coordinate space which is comparable with the Selection Box, use: FVector projected = this->Project( iter->GetActorLocation( ) ); Comparison is done by edit CoolPlugin.uplugin and change "RunTime" to "Editor". how do you iterate over all the actors in the world of a specific class from an AActor based class?

GetActorOfClass () returns the first actor found of a specific class instead of all actors, so if you have 2 actors in the world, it will return only the first found.

The latter is probably more useful, as well as being a bit more user-friendly, but takes more steps to set up. C++11 template <class Category, class T, class Distance = ptrdiff_t, class Pointer = T*, class Reference = T&> class iterator; For example - GetWorld() is part of both UWorld and AActor, so including GameFramework/Actor.h or World.h would allow compilation when using GetWorld(). In your GameMode method described above, you would return the PlayerStart actor that corresponds with the appropriate team. You signed in with another tab or window. For any element you need localized add the data-l10n-id attribute and pass the namespace and key of the translated FText e.g. BaseMesh->SetWorldScale3D(FMath::Lerp(BaseMesh->GetComponentScale(), FVector(2.f, 2.f, 2.f), 0.05f)); This page exists to try and remedy that.
