If I use a setter, it should then change my private classes attribute's value right? However that's not the case, it's just giving me the default value of the private attribute when I use the setter. I am finding the distance travelled value with a getter.
Player.h
#pragma once
class Player
{
public:
void setForestDistanceTravelled(int amount);
int getForestDistanceTravelled();
private:
unsigned short int forestDistanceTravelled = 0;
};
Player.cpp
#include "Player.h"
void Player::setForestDistanceTravelled(int amount)
{
forestDistanceTravelled += amount;
}
int Player::getForestDistanceTravelled()
{
return forestDistanceTravelled;
}
forest.cpp
void welcomeToForest()
{
Forest forest;
Player player;
std::string userInput;
system("cls");
std::cout << "Your current distance is: " << player.getForestDistanceTravelled();
std::cin >> userInput;
if (userInput == "1")
{
unsigned short int playerDist = 0;
system("cls");
playerDist = forestDistanceRand();
player.setForestDistanceTravelled(playerDist);
welcomeToForest();
}
}

As Yksisarvinen states in the comments, the problem lays in new instances of the Player object spawning again and again with each recursion of welcomeToForest().
You just want to isolate the recursive bit of that function into its own function, that accepts the Player object as an outside parameter.
Something like below should work, whilst preserving the recursive logic of the program:
void recursiveBit(Player& player_)
{
std::string userInput;
system("cls");
std::cout << "Your current distance is: "
<< player.getForestDistanceTravelled();
std::cin >> userInput;
if (userInput == "1")
{
unsigned short int playerDist = 0;
system("cls");
playerDist = forestDistanceRand();
player_.setForestDistanceTravelled(playerDist);
recursiveBit(player_);
}
}
void welcomeToForest()
{
Forest forest;
Player player;
recursiveBit(player);
}
