I've been working on this player class all day and now I get this error when I build everything after I passed all of the debugging. It's my first time really messing with headers/classes and SFML. Also I'm new to video game programming so I still lack a lot of the intuition.
These are my exact two errors-19 error LNK2019: unresolved external symbol "public: bool __thiscall Player::load_player(void)" (?load_player@Player@@QAE_NXZ) referenced in function _main C:\Users\OverLordSupreme\Documents\Visual Studio 2012\Projects\Playgrounds\Playgrounds\main.obj DIM
Error 20 error LNK1120: 1 unresolved externals C:\Users\OverLordSupreme\Documents\Visual Studio 2012\Projects\Playgrounds\Debug\DIM.exe DIM
Forewarning- I commented out some code for various reasons, so everything not commented is how I intend for this program to work.
The main file:#include <SFML/Graphics.hpp>
#include <math.h>
#include <iostream>
#include "tile_class.cpp"
#include "player.h"
using namespace sf;
int main()

The Player hpp file#include <SFML/Graphics/Sprite.hpp>
#include <SFML/Graphics/Drawable.hpp>
#include <SFML/Graphics.hpp>
using namespace sf;
class Player: public Sprite, public Texture
{
public:
Player();
void setPlayer(int current_health, int health_pool, int current_armor, int current_weapon, int weapon_upgrade, int inventory, int speed, Vector2i position);
void setCurrentHealth(int);
void setHealPool(int);
void setCurrentArmor(int);
void setCurrentWeapon(int);
void setWeaponUpgrade(int);
void setInventory(int);
void setSpeed(int);
void setPosition(Vector2i);
int getCurrentHealth();
int getHealPool();
int getCurrentArmor();
int getCurrentWeapon();
int getWeaponUpgrade();
int getInventory();
int getSpeed();
Vector2i getPosition();
void playermove(Vector2i);
bool load_player();
private:
int player_states[7];
Vector2i player_position;
Sprite playerSprite;
int current_health;
int health_pool;
int current_armor;
int current_weapon;
int weapon_upgrade;

int speed;
Vector2i position;

And finally the player cpp file#include <SFML/Graphics.hpp>
#include "player.h"
#include <iostream>
using namespace sf;
using namespace std;

void Player::setPosition(Vector2i position)
{player_position=position;}
int Player::getCurrentHealth()
{int current_health=player_states[0];
return current_health;}
int Player::getHealPool()

return current_weapon;}
int Player::getWeaponUpgrade()

return weapon_upgrade;}
int Player::getInventory()

return inventory;}
int Player::getSpeed()
{int speed=player_states[6];
return speed;}
Vector2i Player::getPosition()
{Vector2i position=player_position;
return position;}
bool load_player()
{
Texture player_texture;
if (!player_texture.loadFromFile("face_right"))
{
cerr<< "Texture error" << endl;
return false;
}
Sprite player;
player.setTexture(player_texture);
return true;
}
Any help with this would be awesome! I did try to rename the whole project from "Playgrounds" to "DIM", I feel like that might be helpful to know.
Also while I'm posting this, if anyone could critique my coding that'd be great. Like I said I'm new to this stuff including C++ so I don't know if there's any more ideal ways to go about what I'm doing.
