Passing entity constructor to a player

I created an entity class with its constructor:

class Entity { public:     Entity(sf::Vector2f Size, sf::Vector2f Position, std::string File_name, int Damage, int Life, float Speed);     int Entity_damage, Entity_life, Counter = 0, Direction = 2;     float Entity_movement_speed;     std::shared_ptr< sf::Texture > Entity_texture;     sf::Vector2f Map_margin;     sf::RectangleShape Entity_rect;   }; 

The Constructor:

Entity::Entity(sf::Vector2f Size, sf::Vector2f Position, std::string File_name, int Damage, int Life, float Speed) {     Entity_rect.setSize(Size);     Entity_rect.setPosition(Position);     Entity_texture = Shared_resources::Acquire(File_name);     Entity_rect.setTexture(&*Entity_texture);     Entity_damage = Damage;     Entity_life = Life;     Entity_movement_speed = Speed; } 

and now I have a player class which inheritances from entity, but i don’t know how to access entity constructor.
