在角色的头文件中，添加一个布尔变量，设为共有状态，用来判断是否携带目标物体，并暴露给蓝图，类型为仅蓝图可读

    UPROPERTY(BlueprintReadOnly,Category="Gameplay")
    bool bIsCarryingObjective;

当NotifyActorBeginOverlap发生时，检查是否与FPSCharacter中的角色发生重叠

AFPSCharacter* MyCharacter = Cast<AFPSCharacter>(OtherActor);
    if (MyCharacter)
    {
        MyCharacter->bIsCarryingObjective = true;

        Destroy();
    }
