I am attempting to create a simple interface in C++. I have already defined and declared the virtual function, yet Visual Studio claims that NPC.cpp has unresolved external symbols. Here is the relevant code:
IInteractable.cpp:
#include "IInteractable.h"
void IInteractable::Interact()
{
}
IInteractable.h:
UINTERFACE(MinimalAPI)
class UInteractable : public UInterface
{
GENERATED_BODY()
};
class ULTRARPG_API IInteractable
{
GENERATED_BODY()
public:
FText InteractPrompt;
virtual void Interact();
};
NPC.h:
public:
void Interact() override;
NPC.cpp:
void Interact()
{
UE_LOG(LogTemp, Warning, TEXT("Talk"));
}
