Project settings There are many switches in the project settings that will help reduce the build size. The first thing you can do is set Build Configuration to Shipping and enable For distribution:...

Here is information about the following containers: TArray, TSet, TMap, and a basic overview of the TMultiMap and TSortedMap. TArray Let’s start with TArray. TArray is a dynamically sized array, similar to std::vector in the standard library....
This is a short article on how to convert an enumerator to FString in Unreal Engine. Blueprints In Blueprints, it is easy to convert all supported enumerators to FString. Simply drag your enumerator to the required pin, which will automatically add the necessary conversion node. C++ In C++, the implementation varies based on the type of enum used. Unreal Reflection System If you want to use a solution that is compatible with the Unreal Reflection System and accordingly uses UENUM, there is an in-built method named UEnum::GetValueAsString....
Concept There are two main types of libraries: Static and Dynamic (also called Shared). A static library is statically linked to a program and is available at compile time. A dynamic (or shared) library, on the other hand, is dynamically linked and available at runtime. Static linking assumes that the library code is built into the final block of code, unlike dynamic linking. But the process of dynamic linking takes some time....
