Adding AURTrackingComponet to Custom Class in C++

[chipper10]

Hello,

Thank you very much for the plugin, I am able to load the example projects and it works well.

The next I wanted to do was create a new C++ class "Trackable Object" that already comes with the proper mesh and tracking target. I want to do this so I can generate the objects on the fly later.

What is the proper method to add the AURTrackingComponent to a C++ class?

CreateDefaultSubobject gives me a linker error. I've tried a few other things to no avail.

Is it possible to do this and what's the best way?

Thank you

Please try adding "AugmentedUnreality" to PublicDependencyModuleNames in YourProject.Build.cs.
It may cause the plugin to be used in C++ linking.

Thanks for the response. I had to do this to get it to compile so that was already done. Somehow the linker still throws an error. So have you successfully been able to create an object of type AURTrackingComponent in C++ before? Can you share the code you used if so? Thank you!

Could you post the linker error message here? Which symbols are missing?

This is the code I'm using:
UAURTrackingComponent* trackingComponent;
trackingComponent = CreateDefaultSubobject<UAURTrackingComponent>(TEXT("Tracker"));

and here is the linker message:
Error LNK2019 unresolved external symbol "private: static class UClass * __cdecl UAURTrackingComponent::GetPrivateStaticClass(void)" (?GetPrivateStaticClass@UAURTrackingComponent@@CAPEAVUClass@@XZ) referenced in function "public: __cdecl ATrackable_Part::ATrackable_Part(void)" (??0ATrackable_Part@@QEAA@XZ) AugmentedUnrealityEx C:\Users\keselmld\Documents\Projects\AugmentedUnrealityEx\Intermediate\ProjectFiles\Trackable_Part.cpp.obj 1
As I understand it, the CreateDefaultSubobject template calls UAURTrackingComponent::GetPrivateStaticClass(void) as part of the creation process and this function does not exist. Let me know if I'm misunderstanding.

Thanks again!
