Super isn't a class or namespace name

Development Programming & Scripting C++

Good evening!

I’m getting what is, apparently, the consequence of a circular dependency that I’m not catching: the compiler is complaining about the Super inside one of my method declarations, informing me that Super is not a class or a namespace name neither (error C2653). I’m not seeing the issue here, can you guys point me what’s going on here? Here are two snapshots:

Base class:

Derived class:

Thanks! :slight_smile:

I could be wrong on this but isn’t the “Super” class is defined by the UnrealHeaderTool? If so, you have to include your class’s generated header file as well.

#include FOrbitDataTask.generated.h

I recreated your situation and this is my solution:

To use Super::, you require a GENERATED_BODY() macro, a UCLASS() macro in front of the declaration, inheritance from UObject, and to include your generated.h file:
classes
Ignore the IntelliSense errors; it still hasn’t updated, but it compiles with no problems.

I’ve found the generated.h file doesn’t exist unless you use UObject.

The class you’re inheriting from is an Unreal class, but it isn’t a UCLASS (UObject) or a UStruct so I don’t think you can use the GENERATED_BODY or UPROPERTY macros in your code unless you really know what you’re doing. Super is a convenience thing you get when using UStructs and UObjects, and won’t work in your case.

Just use the parent class name explicitly, like in “normal” C++. In your case that’d be FGenericTask::DoWork();

Sorry for the delayed reply, guys. I was sick, and turned my PC on just now.

Yes, what @anonymous_user_4aa5607e1 said is true, I figured out myself in the past days (thanks to Unreal Property System (Reflection) (unrealengine.com)): I’m not using an UObject derived class, but a FNonAbandonableTask, and I should use the parent class explicit name ParentClassName::DowWork(), since UE4 doesn’t support multiple inheritance and I can’t inherite both FNonAbadonableTask and UObject (it would be a weird class thou).

You’re guys are right too, @anonymous_user_7db7de02 and @STRiFE.x, but for what I want to do, isn’t possible.

Thanks guys!
