Issue creating my Pokemon game global organisation - c++

Question

For context I am recreating a Pokemon game in c++(I am new to C++ i have only 1 year xp in programming and i was programming in C). But i have issue with the organisation of my code.
Here is my problem: I don't know what to put in class and what to put in struct.
For example in my current code my Pokemon and my Attaque are 2 different class. I have done that because of the fact that I want the 2 of them to be init with info in a file. But if the Pokemon are fighting they need to have access to the Attaque. But when generating my Pokemon some stat change when it's affected by item. Like shiny % is affected by Shiny Charm. So i need to have access to my bag too.
The problem here is that I am making a lot of class friend (right now Attaque is friend of Pokemon and Pokemon is friend of bag). And I have read that it's maybe an organisation code issue.
I have thought about making getters for example for the Shiny Charm, but I don't know if it's good or not.
Here is my Pokemon class. nature_e, status_e and type_e are enum class.
class Pokemon {
private:
bool m_is_shiny { false };
bool m_is_pokerus { false };
short m_level { 0 };
int m_id { 0 };
int m_exp { 0 };
std::array<int, 2> m_texture_coord { 0, 0 };
std::array<unsigned char, 6> m_iv {0, 0, 0, 0, 0, 0};
std::array<unsigned char, 6> m_ev {0, 0, 0, 0, 0, 0};
std::array<unsigned char, 6> m_base_stat {0, 0, 0, 0, 0, 0};
std::array<unsigned char, 8> m_stat {0, 0, 0, 0, 0, 0, 0, 0};
nature_e m_nature {nature_e::NONE};
status_e m_status {status_e::NONE};
std::array<type_e, 2> m_type {type_e::NONE, type_e:: NONE};
Texture2D m_texture;
std::string m_name { "Non" };
std::string m_item { "non" };
std::string m_sprite_path { "None" };
std::array<Attaque, 4> m_atk { Attaque(), Attaque(), Attaque(), Attaque() };
public:
Pokemon()
{
}
Pokemon(int id, short level);
};
Here is my Attaque class:
class Attaque {
private:
bool m_phy_or_spe;
int m_damage;
type_e m_type;
double m_effect_precision;
double m_precision;
std::string m_name;
public:
Attaque()
{
}
Attaque(int id);
};
