1。新建一个基类，用于玩家可拾取物品的父类

然后

// Fill out your copyright notice in the Description page of Project Settings.#pragma once#include "CoreMinimal.h"
#include "Components/SphereComponent.h"
#include "GameFramework/Actor.h"
#include "XMBPickUpBase.generated.h"UCLASS()
class ARPG_GRIVITY_API AXMBPickUpBase : public AActor
{GENERATED_BODY()public:	AXMBPickUpBase();protected://UPROPERTY(VisibleAnywhere,BlueprintReadOnly,Category = "Pick Up Interaction")USphereComponent* PickUpCollisionSphere;//UFUNCTION()virtual void OnPickUpCollisionSphereBeginOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult);};

// Fill out your copyright notice in the Description page of Project Settings.#include "Items/PickUps/XMBPickUpBase.h"
#include "Components/SphereComponent.h"// Sets default values
AXMBPickUpBase::AXMBPickUpBase()
{PrimaryActorTick.bCanEverTick = false;PickUpCollisionSphere = CreateDefaultSubobject<USphereComponent>(TEXT("PickUpCollisionSphere"));SetRootComponent(PickUpCollisionSphere);PickUpCollisionSphere->InitSphereRadius(50.f);PickUpCollisionSphere->OnComponentBeginOverlap.AddUniqueDynamic(this,&ThisClass::OnPickUpCollisionSphereBeginOverlap);}void AXMBPickUpBase::OnPickUpCollisionSphereBeginOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor,UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{}

再创建该类的子类，用于制作玩家可拾取的功能性石头道具

2。再根据创建的子类创建一个蓝图，做为蓝图的基类，往里面添加一个niagara

在创建此蓝图的子类，用于分类不同功能的可拾取性道具
