Consumable Interactable Pattern

Type: Requires external gameplay system

This is the "safe pickup" pattern: the interactable only disappears if your own gameplay system confirms the reward or consumption succeeded.

Example

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "Data/EDInteractionTypes.h"
#include "MyConsumableActor.generated.h"

class UArrowComponent;
class UEDInteractableComponent;
class USceneComponent;
class UStaticMeshComponent;

UCLASS()
class AMyConsumableActor : public AActor
{
	GENERATED_BODY()

public:
	AMyConsumableActor();

protected:
	virtual void BeginPlay() override;

	UPROPERTY(VisibleAnywhere)
	TObjectPtr<USceneComponent> Root;

	UPROPERTY(VisibleAnywhere)
	TObjectPtr<UStaticMeshComponent> VisualMesh;

	UPROPERTY(VisibleAnywhere)
	TObjectPtr<USceneComponent> WidgetHolder;

	UPROPERTY(VisibleAnywhere)
	TObjectPtr<UArrowComponent> CenterArrow;

	UPROPERTY(VisibleAnywhere)
	TObjectPtr<UEDInteractableComponent> InteractableComponent;

	UFUNCTION()
	void HandleInteractionSuccessful(const FEDInteractionEventContext& Context);
};

#include "MyConsumableActor.h"

#include "Components/ArrowComponent.h"
#include "Components/EDInteractableComponent.h"
#include "Components/SceneComponent.h"
#include "Components/StaticMeshComponent.h"
#include "GameFramework/Pawn.h"

AMyConsumableActor::AMyConsumableActor()
{
	Root = CreateDefaultSubobject<USceneComponent>(TEXT("Root"));
	SetRootComponent(Root);

	VisualMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("VisualMesh"));
	VisualMesh->SetupAttachment(Root);
	VisualMesh->ComponentTags.Add(FName(TEXT("DimensionComponent")));

	WidgetHolder = CreateDefaultSubobject<USceneComponent>(TEXT("WidgetHolder"));
	WidgetHolder->SetupAttachment(Root);
	WidgetHolder->ComponentTags.Add(FName(TEXT("WidgetHolderComponent")));

	CenterArrow = CreateDefaultSubobject<UArrowComponent>(TEXT("CenterArrow"));
	CenterArrow->SetupAttachment(VisualMesh);
	CenterArrow->ComponentTags.Add(FName(TEXT("CenterComponent")));

	InteractableComponent = CreateDefaultSubobject<UEDInteractableComponent>(TEXT("InteractableComponent"));
}

void AMyConsumableActor::BeginPlay()
{
	Super::BeginPlay();
	InteractableComponent->OnInteractionSuccessful.AddDynamic(this, &AMyConsumableActor::HandleInteractionSuccessful);
}

void AMyConsumableActor::HandleInteractionSuccessful(const FEDInteractionEventContext& Context)
{
	APawn* InstigatorPawn = Context.Instigator ? Context.Instigator->GetPawn() : nullptr;
	if (!InstigatorPawn)
	{
		return;
	}

	// Placeholder for your own inventory/stat/progression system.
	const bool bConsumed = TryConsumeOnPlayer(InstigatorPawn);
	if (!bConsumed)
	{
		return;
	}

	Destroy();
}

Why this matters

This avoids deleting the actor when the actual gameplay reward fails.
