Unreal engine 4 c++ tutorial portable#
The code written in C++ is very portable and is now used as a tool by many game developers. Although designed primarily for first-person shooters, it was later used in various game genres. The "Pointer to incomplete class type" error is often times an indicator that you're missing an #include. Unreal Engine is a game engine developed by Epic Games and first used in the 1998 Unreal first-person shooter. Otherwise, you'll need to #include the header file. In short, if you are just passing pointers to a class around, you can just forward declare with class ClassNameHere and be done with it. Include #include "Components/StaticMeshComponent.h" When you need to use a class and forward declaring it isn't enough, go to the Unreal Engine 4 documentation and search for the class you are trying to use.įor example, searching for UStaticMeshComponent will bring you to its API page, and it says: You'll likely need to add other #include directives. Unfortunately, there are still many old tutorials & guides what don't fully reflect this change.įor instance, because you're using UStaticMeshComponent (without forward declaring with class UStaticMeshComponent), you must have #include "Components/StaticMeshComponent.h" at the top of that file.įor ConstructorHelpers, you must have #include "UObject/ConstructorHelpers.h".

This change was made to make compilation faster. One of the first things I wanted to do with Unreal Engine 4 (UE4) was to reload the. Starting with version 4.15, the default configuration requires that you must have additional #include directives when you reference most classes.
