Create a new header file in the Header Files/GameObjects filter called TransformComponent.h and add the following code:
#pragma once
#include "Component.h"
#include<SFML/Graphics.hpp>
using namespace sf;
class Component;
class TransformComponent : public Component {
private:
    const string m_Type = "transform";
    Vector2f m_Location;
    float m_Height;
    float m_Width;
public:
    TransformComponent(
        float width, float height, Vector2f location);
    Vector2f& getLocation();
    Vector2f getSize();
