Skill: Create Blueprint Interface

Description

Create a Blueprint interface with C++ backing for interactable objects.

Arguments

• {{arg}}: Interface name (without 'I' prefix, e.g., Interactable)

Steps

1. Create header I{{arg}}.h:

   UINTERFACE(MinimalAPI)
   class U{{arg}} : public UInterface { GENERATED_BODY() };
   class I{{arg}} {
       GENERATED_BODY()
   public:
       UFUNCTION(BlueprintNativeEvent)
       void Interact(AActor* Interactor);
   };
   

2. Implement on an actor:

   class AMyActor : public AActor, public I{{arg}} {
       virtual void Interact_Implementation(AActor* Interactor) override;
   };
   

3. Call via interface (handles both C++ and Blueprint-implemented interfaces correctly):

   if (TargetActor->GetClass()->ImplementsInterface(U{{arg}}::StaticClass()))
   {
       I{{arg}}::Execute_Interact(TargetActor, this);
   }
