    继续完善PickUP类

    直接上图

    其中需要注意的是IsActive函数设置的蓝图属性是BlueprintPure 表明该函数只是读取数据 不做修改类似C#中的get域

    最终。h

    #pragma once

    #include "GameFramework/Actor.h"

    #include "PickUp.generated.h"

    UCLASS()

    class BATTERYCOLLECTOR_API APickUp : public AActor

    {

    GENERATED_BODY()

    public:

    // Sets default values for this actor's properties

    APickUp();

    protected:

    // Called when the game starts or when spawned

    virtual void BeginPlay() override;

    UFUNCTION(BlueprintPure, Category = "Pickup")

    bool IsActive();

    UFUNCTION(BlueprintCallable, Category = "Pickup")

    void SetActive(bool NewPickupState);

    public:

    // Called every frame

    virtual void Tick(float DeltaTime) override;

    FORCEINLINE class UStaticMeshComponent* GetMesh()const { return PickupMesh; }

    protected:

    bool bIsActive;

    private:

    UPROPERTY(VisibleAnyWhere, BlueprintReadOnly, Category = "Pickup", meta=(AllowPrivateAccess = "true"))

    UStaticMeshComponent* PickupMesh;

    };

    最终。cpp

    // Fill out your copyright notice in the Description page of Project Settings.#include "BatteryCollector.h"#include "PickUp.h"// Sets default valuesAPickUp::APickUp(){ // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.PrimaryActorTick.bCanEverTick = false;PickupMesh = CreateDefaultSubobject(TEXT("PickupMesh"));

    RootComponent = PickupMesh;

    bIsActive = true;

    }

    // Called when the game starts or when spawned

    void APickUp::BeginPlay()

    {

    Super::BeginPlay();

    }

    // Called every frame

    void APickUp::Tick(float DeltaTime)

    {

    Super::Tick(DeltaTime);

    }

    bool APickUp::IsActive()

    {

    return bIsActive;

    }

    void APickUp::SetActive(bool NewPickupState)

    {

    this->bIsActive = NewPickupState;

    }

    进入UE4 找到PickUP 右键 创建子类蓝图
