Thread: C++ Text game code

Hello.
I have been experimenting with some code iv found and iv made a 2-player game. I am just learning how to write code and this is the first project I have done that can be expanded and changed.

This is definitely not finished and im sorry if its a bit sloppy and the comments don't make sense. Iv been too busy learning and having fun to keep tidy. You should see my flat!

I plan to add the following later on:

menu's and to be able to pick character.

new characters like mage or wizard.

basic AI for single player game.

Any comments or suggestions would be awesome.

Code:

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{   
    int damage = 0;
    int player1HP = 100;
    int player2HP = 100;
    int player1MP = 0;
    int player1ATK = 2;
    int player2ATK = 2;
    int potionSTR = 3;
    int potionNUM1 = 3;
    int potionNUM2 = 3;
    int turn = 1;
    char enter;


    //Combat

    cout << "welcome to Atco's savage fighting game!\n\nEnter 1: ";
    cin >> enter;
    
    if (enter == '1')
         cout << system("CLS");
    else system ("CLS");

    while (player1HP > 0 && player2HP > 0)
    {
        system("CLS");
        cout << "Berserker Warrior's HP = " << player1HP << endl;
        cout << "Berserker Warrior's rage = " << player1MP << endl;

It is pointless lol. I made that bit just so i could understand how clearscreen worked and left it.

I'm don't know how to get it to check for upper case yet so i will have to do some research. Thanks for the input

I have heard of and seen this thing called class but up till now have only used main. I have no idea what an enum is and iv not read anything about the constructor. You have given me much to think about my next priority.

I will post what i do into the games section next. Thank you for finding the time to read my post and give me advice so I can learn more. If I carry on the way im going its going to get far too complicated so nice one for giving me a heads up.

I'l get on it but now it's time for sleep! thanks
