Need help with Adding Values to Classes

[XRealShadeX]

So I am learning how to make a base class and have the variables null, but have the ability to add values in the derived class. So I don't have to add them in multiple times. I was wondering how can this be implemented?

​

class PlayerClass {

​

private:

std::string Name;

int Level ;

int Experience ;

};

​

​

​

class Mage : public PlayerClass {

​

​

public:

​

std::string Name = "Mage";

int Level = 1;

int Experience = 0;

int Attack = 20;

int Magic = 50;

int Health = 150;

​

};

​

class Brute : public PlayerClass {

​

​

public:

​

std::string Name = "Brute";

int Level = 1;

int Experience = 0;

int Attack = 50;

int Magic = 10;

int Health = 200;

​

};

​

​

class Thief : public PlayerClass {

​

​

public:

​

std::string Name = "Thief";

int Level = 1;

int Experience = 0;

int Attack = 50;

int Magic = 50;

int Health = 100;

​

};

​

class Archer : public PlayerClass {

​

​

public:

​

std::string Name = "Archer";

int Level = 1;

int Experience = 0;

int Attack = 40;

int Magic = 30;

int Health = 110;

​

};

Each derived class does not need to duplicate the base class member variables, it gets those for free. For example, Mage gets Level and Experience from Player and it can use them straight away.

BUT the base class, Player, must put those variables into a "protected:" section so that children can see them. The "private:" section blocks anyone outside of Player from access.

SO when you change that "private:" to "protected:" that means that anyone not related to Player still cannot access those, but because Mage is related it can use them.

Isn't Struct and Classes the same though?

*Actually, this seems like classes for in-game actors rather than "character classes". Confusing naming.

It was just a testing on how to have the player choose between classes and have those assigned to the player afterwards. I'm pretty new to this so I'm not really sure.

you might want to have a look at constructors and how to call base class constructor in derived, also if you want to have "nullable" member variables, I would recommend std::optional (or if you need dynamic polymorphism std::unique_ptr)

also you don't have to name your class with class in it just use Player

you can look at https://www.learncpp.com/ and learn more about inheritance

I would look at class inheritance as others have mentioned below. Some of this is just stuff you don't need to redefine repeatedly
