    Need help with concepts for first game

    Hey I'm making my first game. I've decided to do what everyone else seems to start off doing - a text based rpg.

    However, my aspirations have led me to be clueless. Just what the heck am I supposed to accomplish as a goal? I mean it's so open-ended and stuff. THats where I need your help. Please, what sort of goals should I make? I don't want to make a game without goals in mind.

    The goal of a classic RPG is simple: Some bad guy/thing is threatening everyone by doing something bad. The goal is to walk around and beat his stronger minions that are conveniently placed at the bottom of various dungeons that are filled with his weaker minions. The bosses are also conveniently comparable to you in strength at all times. Fill in the blanks and you're solid.
    Just because I don't care doesn't mean I don't understand.

    Maybe concepts was the wrong word. Maybe mechanics is a better one. I don't want you to write it for me or anything, but I just need some slight guidance. Like how to store a character and such. So far I have really stupidly basic ideas that they're not ideas .

    Code:
    //Text Based RPG v1.0
    //First implementations
    
    #include <iostream>
    using namespace std;
    
    class Human {
          public:
          short int h_BaseHitPoints;
          short int h_BaseStrength;
          short int h_BaseManaPoints;
          short int h_BaseAccuracy;
    };
          
    class Dwarf {
          public:
          short int d_BaseHitPoints;
          short int d_BaseStrength;
          short int d_BaseManaPoints;
          short int d_BaseAccuracy;
    };
          
    class Elf {
          public:
          short int e_BaseHitPoints;
          short int e_BaseStrength;
          short int e_BaseManaPoints;
          short int e_BaseAccuracy;
    };
          
    int main() {
        cout << "\t\t\tWELCOME TO TEXT RPG v1.0!" << endl;
        cin.get();
        return 0;
    }

    I notice you've created 3 separate classes that have the exact same members that differ only by the naming convention. Perhaps you should just make one single Unit class. If you want to specialise the Unit class, use inheritance.

    Ya, much better. It makes sense to break the game into several different engines that work together, like the battle engine, the world engine, the shop engine, etc... You can use a common base class for players and mosters alike, then specialize in the children. For example, all characters would have hit points, but only the player characters would have equipment lists. The non-player characters might need special functions for making decisions while the player characters would need some kind of interface for the user.

    You probably want to start with the battle engine, because it's a big part of the game, and you can figure out what you would need as far as attributes and equipment.
    Just because I don't care doesn't mean I don't understand.

    As Dante Shamest said if all of your units are going to have the exact same parameters then just make one class, and just make each unit different with the constructor. Then if you are going to have units with different parameters use inheritance. (this is just deeper calarification of what Dante Shamest said)

    Also, I don't think DOS text-based games are of much use for SAVING. Ha, makes me laugh. Seriously, that's stupid right?

    Also, I've always wondered about characters like storing an answer and then computing it or giving you the result. How would I implement a Name save for the Character ?

    I have brought you a fountain for your game... I would also give your characters some kind of location variables (i.e x,y).

    Code:
    cout << "You arrive at the fountain of forgiveness..." << endl;
    cout << "You begin to pray..." << endl;
    
    int opt = rand()%3;
    
    if(opt == 0)
    {
         ++health;
         cout << "You have been forgiven" << endl;
    }
    if(opt == 1)
    {
         --health;
         cout << "You will suffer for eternity" endl;
    }
    
    if(opt == 2)
         cout << "No Reply...";

    I've never understood the rand() function. OBVIOUSLY it means random, but the %3 i have no idea about. I mean I just need context clues is all. And is there a specified header for that function?

    I'm also assuming that opt is option. Woohoo lol. Makes sense almost.

        cin.get();
        return 0;
    }
    Yeah compiler errors
    The main one is that i'm readin character input wrong when choosing the class. I mean how exactly should I read their input?

    Basically the mod (%) operator in this case restricts the range of random numbers. In general you can get a random number in the range 0 to (n - 1) by modding by n. So in the % 3 case you will either get 0, 1, or 2 as a result. Located in the stdlib.h header for C or cstdlib for C++. Opt is probably short for option as you suggested.

    Oh! I kind of thought that the %3 meant that there were 3 possible solutions so that's cool thanks for the clarification. Now for help compiling this monstrosity above.

    Okay, here is one way you could accomplish what you are attempting to do. Have you ever used STL's string class? It's has a lot of functionality but you don't need to know all of the underlying mechanics to appreciate it. Just include <string> at at the top of your program. Now instead of having CharacterClass being a 1 element char array, we will change that to be a string.

    Code:
    string CharacterClass;
    Reason: You can't have a 1 element character array and expect the user to just enter one character. It would be very easy for someone to accidently overflow that buffer. Even if they did just enter one character you would need a 2 element array for the null terminator at the end.

    So now we have the value d, h, or e hopefully in our string. Now to test it we can simply do an equality comparison

    Code:
    if(CharacterClass == "e")
    Note: Before you had just d when comparing your 1 element array. What you wanted was 'd' for a literal character. Instead, your compiler was looking for a variable named d which didn't exist.

    If you don't feel comfortable using string's, you might want to look into switching it so the user enters a number to determine which character class he wants.
    You can read more about STL string class here:
    http://www.msoe.edu/eecs/cese/resources/stl/string.htm

    Edit Note: You assign CharacterClassvar to Dwarf or Elf or Human but those are uninitialized variables. I'll trust that you just put that there temporarily, because nothing good will come from that assignment.

    Here, I fixed the errors and modified it a bit with whatever I noticed.

          CharacterClass = toupper(CharacterClass); //make sure its upper case, so d and D will work.
    
          switch (CharacterClass) {
            case 'D':
                           CharacterClassvar = Dwarf;
                           Player.BaseHitPoints = 50;

                           CharacterClassvar = Elf;
                           Player.BaseHitPoints = 40;
                           Player.BaseStrength = 1;

                           Player.BaseStrength = 3;
                           Player.BaseManaPoints = 30;
                           Player.BaseAccuracy = 5;
                           cout << "Welcome human to the world of Bazeor full of treachery and villany." << endl;
            break;
            default:
                           cout << "Invalid entry.";
                           continue;
            break;
          }
    
          break;
        }
    
        cin.ignore();
        cin.get();
        return 0;
    }
    The reason it was giving errors wasnt because of your input, but because you were trying to compare: CharacterClass with D, which it though was a variable, for a char you must put 'D', and for strings you put "string here". I switched your if statements to a switch statement, for clarity, and the default: incase other than D E or H are entered; added an to upper case effect incase they enter d or D or h or H, it will work either way; also added a while statement so it goes back to the class choice if they enter anything but D E or H; also added cin.ignore() before cin.get() because it didnt pause (because you previously had used cin, you must use ignore before cin.get from not on for it to have a pause effect).
    Warning: Have doubt in anything I post.

        cin.ignore();
        cin.get();
        
        cout << "In a distant town not far from Macksgrail is a young " << endl; 
       
        
        return 0;
    }
    I really want to incorporate the character class and the character name so like if the character was Elf Jim it would be better than just Elf, you know? I tried it with characters but i got a BAJILLION of errors.
