Now we have a class for a simple object (SimpleObj) we can use it. This will create a class for your game, and it will create objects of the SimpleObj class.
Game.h
Remember a class in C++ needs a header to declare the variables and to specify the methods it contains. Remember it provides no implementation for the methods:
#pragma once
class Game
{
public:
Game(); //standard constructor
~Game(); //standard destructor
//list the functions we want to have (called methods in C++)
void Update();
};
Game.cpp
The Game.cpp file provides the implementation of the methods within the header file. The includes are need to be able to access the header files.
#include "Game.h"
#include "SimpleObj.h"
Game::Game() {}; // just need to exist at the moment
Game::~Game() {};
void Game::Update()
{
SimpleObj Bobby1; // create a Simple Object withe the class name Bobby1
SimpleObj Bobby2;
Bobby1.m_MyName = "Bobby1"; // Give Bobby 1 his name
Bobby2.m_MyName = "Bobby2"; // Give Bobby 2 his name
// now we will do a loop;
for (int i = 0; i < 200; i++)
{
Bobby1.Update(); // do Bobby1's update
Bobby2.Update(); // do Bobby2's update
}
return;
};
This code above mainly defines the Update method of the game class, in this case it will create 2 SimpleObj, assign each a name, and then run the update method for the objects 200 times.
Usage
This declares and defines what a game is, we now need to create an object of it in the 'main.cpp' code:
#include "Game.h"
int main(int argc, char *argv[])
{
Game TheGame; // create an instance of game.
for (int i = 0; i < 10; i++)
{
TheGame.Update();
}
}
