Constructor Asking for Wrong Number of Arguments

Development Programming & Scripting
1

I have build a class in Unreal called Groundmode

GroundMode.h:
#pragma once

#include "CoreMinimal.h"
#include "UObject/NoExportTypes.h"
#include "Components/BoxComponent.h"
#include <NMR\GroundDirection.h>
#include "GroundMode.generated.h"

UCLASS()
class NMR_API UGroundMode : public UObject
{
	GENERATED_BODY()

	public:
		UGroundMode();   
};

GroundMode.cpp:

#include "GroundMode.h"

UGroundMode::UGroundMode() {}

I want to be able to instantiate this class in another class.
PlayerPhysicsCollisionInfo.h

#include "CoreMinimal.h"
#include "Components/ActorComponent.h"
#include "GroundMode.h"
#include "PlayerPhysicsCollisionInfo.generated.h"


UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
class NMR_API UPlayerPhysicsCollisionInfo : public UActorComponent
{
	GENERATED_BODY()

public:	
	UPlayerPhysicsCollisionInfo();

	UGroundMode downMode;
	UGroundMode upMode;
	UGroundMode leftMode;
	UGroundMode rightMode;
};

PlayerPhysicsCollisionInfo.cpp:
#include “PlayerPhysicsCollisionInfo.h”

    void UPlayerPhysicsCollisionInfo::BeginPlay()
    {
    	Super::BeginPlay();
    	downMode = new UGroundMode();
    	upMode = new UGroundMode();
    	leftMode = new UGroundMode();
    	rightMode = new UGroundMode();
    }

When I attempt to create instances of UGroundMode with the new keyword I get the following compile error:
D:\Documents\Unreal Projects\NMR\Source\NMR\PlayerPhysicsCollisionInfo.cpp(25) : error C2661: ‘UGroundMode::operator new’: no overloaded function takes 1 arguments

What am I doing wrong? The constructor takes no arguments not 1.

Normally you should use NewObject<Class>(), but I think new operator got overloaded to do that for you. The missing argument is most likely Outer which you would also need to state in NewObject, it a object that life cycle of you object will be tied if outer dies you object dies with it, it part of garbage collection convention makes sure that object is not left out in memory
