Calling Blueprint-defined interface functions from C++

While the previous recipes have focused on C++ being usable in Blueprint, such as being able to call functions from C++ in Blueprint, and override C++ functions with Blueprint, this recipe shows you the reverse: calling a Blueprint-defined interface function from C++.

How to do it...

1. Create a new UInterface called Talker (Creating the UTalker/ITalker classes):

2. Add the following UFUNCTION implementation:

#pragma once

#include "CoreMinimal.h"
#include "UObject/Interface.h"
#include "Talker.generated.h"

// This class does not need to be modified.
UINTERFACE(MinimalAPI)
class UTalker : public UInterface
{
    GENERATED_BODY()
};
