Class objects not declared in scope - c++

Question

I am currently experiencing a problem that I just can't seem to wrap my head around why it would be occurring.
In my (Unsplit)program I've created a class that defines an entity object and is able to handle its creation and variables just fine (as I've tested before adding
std::string getName(Entity)const;
std::string getType(Entity)const;
int getDamage(Entity)const;
int getHealth(Entity)const;
But when I do... Even though they are already declared publicly in the class and I am fully able to call Initialize(); Attack(); and PrintStats(); just fine, it doesn't see the other four and therefor are not able to be called.
#include <iostream>
#include <string>
#include <math.h>
#include <stdlib.h> /* srand, rand */
#include <time.h> /* time */
using namespace std;
class Entity
{
public:
Entity() { // default constructor
name = "Human";
type = "Normal";
damage = 1;
health = 100;
}
void printStats();
void Initialize(string, string, int, int); //transformer or setting function
void Attack(Entity&); //observer or getter function
std::string getName(Entity)const;
std::string getType(Entity)const;
int getDamage(Entity)const;
int getHealth(Entity)const;
private://data members and special function prototypes
std::string name;
std::string type;
int damage;
int health;
};
void summonEnemy(Entity&);
int main () {
/* initialize random seed: */
srand (time(NULL));
Entity Player;//declaring new class objects
Entity Enemy;//declaring new class objects
Player.Initialize("Player", "Normal", 10, 90);
summonEnemy(Enemy);
return 0;
}
void summonEnemy(Entity &target) {
target.Initialize("Enemy", "Normal", floor(rand() % 20 + 1), floor(rand() % 100));
cout << "An " << getType(target) << " type " << getName(target) << " has appeared with " <<
getHealth(target) << "HP and can do " << getDamage(target) << " damage.";
}
Error message:
error:'getType' Was not defined in this scope.
error:'getName' Was not defined in this scope.
error:'getHealth' Was not defined in this scope.
error:'getDamage' Was not defined in this scope.
Cut off some code to narrow it down such that only what could be the cause of the problem is showing... But honestly its probably something simple that I am not seeing. Any help appreciated.

Answer 1

You are not calling them correctly. They are members of the Entity class, not standalone functions. Remove the Entity parameters from them, as they already have an implicit Entity *this parameter, and then call them like this:
class Entity
{
public:
Entity(); // default constructor
...
std::string getName() const;
std::string getType() const;
int getDamage() const;
int getHealth() const;
...
};
Entity::Entity()
{
Initialize("Human", "Normal", 1, 100);
}
std::string Entity::getName() const
{
return name;
}
std::string Entity::getType() const
{
return type;
}
int getDamage() const
{
return damage;
}
int getHealth() const
{
return health;
}
void summonEnemy(Entity &target)
{
target.Initialize("Enemy", "Normal", floor(rand() % 20 + 1), floor(rand() % 100));
cout << "An " << target.getType() << " type " << target.getName() << " has appeared with " <<
target.getHealth() << "HP and can do " << target.getDamage() << " damage.";
}

getType is a member function of Entity, so you need to call it on an Entity object:
target.getType();
In the class, you could implement it as:
class Entity {
...
std::string getType() const { return type; }
...
};
The same is true for your other three setters.
