Help With using classes for games.
This is my first attempt at using classes for a program, it is sort of like a "learn how to use class's in c++ test" program for me. Of all the tutorials I have read about them, I couldn't find anything useful to use them with except maybe games (which I don't know how program).
Could anyone share with me some tips about what to change about implementation of them and how I can use them better in the future? (note: this program was only a test of how to use classes not meant to be that great or anything). Thanks in advance for your help.
Code:
#include <iostream>
#include <string>
using namespace std;
char map[50][30] = { 0 };
char message[30];
bool done = false;
class Charactor
{
public:
Charactor();
~Charactor();
void moveup();
void movedown();
void moveleft();
void moveright();
int xpos;
int ypos;
int height;
int width;
int health;
int speed;
} player;
Charactor::Charactor()
{
xpos = 5;
ypos = 15;
height = 1;
width = 2;
health = 100;
speed = 1;
}
Charactor::~Charactor()
{
}
void Charactor::moveup()
{
ypos -= speed;
}
void Charactor::movedown()
{
ypos += speed;
}
void Charactor::moveleft()
{
xpos -= speed;
}
void Charactor::moveright()
{
xpos += speed;
}

{

int x1,x2,y1,y2;
