1.创建一个Actor的c++类

2.创建武器WeaponBase的子类，给玩家的武器

3.进入WeaponBase，只留下构造函数，并且将bCanEventTick改为false，增加组件。

#pragma once#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "WeaponBase.generated.h"class UBoxComponent;UCLASS()
class ARPG_GRIVITY_API AWeaponBase : public AActor
{GENERATED_BODY()public:	AWeaponBase();UBoxComponent* GetWeaponCollisionBox() const { return WeaponCollisionBox; }protected:UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Weapon")UStaticMeshComponent* WeaponMesh;UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Weapon")UBoxComponent* WeaponCollisionBox;};

#include "Items/Weapon/WeaponBase.h"#include "Components/BoxComponent.h"AWeaponBase::AWeaponBase()
{PrimaryActorTick.bCanEverTick = true;WeaponMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("WeaponMesh"));SetRootComponent(WeaponMesh);WeaponCollisionBox = CreateDefaultSubobject<UBoxComponent>(TEXT("WeaponCollisionBox"));WeaponCollisionBox->SetupAttachment(GetRootComponent());WeaponCollisionBox->SetBoxExtent(FVector(20.f));WeaponCollisionBox->SetCollisionEnabled(ECollisionEnabled::NoCollision);
}

4.启动项目，创建XMBWeapon的蓝图类,命名为BP_WeaponBase，再创建这个蓝图类的子类，命名为BP_PlayerWeapon，用于玩家的武器
