Cool text based adventure game

Question

I am looking for general critique of my code and notice of any bugs or errors. I have included the main file and the class files. Also, I'm wondering where would I need comments. Sorry it is such a monster ;).

#include <iostream>

#include "rooms.h"
#include "characters.h"
#include<bits/stdc++.h>

    int y;

void save(vector<vector<Rooms>>& map, Characters& player, int numTurns);
void createOriginalSave(); // Creates original.txt
int load(string filename, vector<vector<Rooms>>& map, Characters& player, vector<Characters>& npcs); // Loads object data from save file
Coord move(string in, vector<vector<Rooms>> map, int x, int y, Characters& player, int moves);
int score (double moves, Characters& player);
void help();
void take(string in, vector<vector<Rooms>>& map, Characters& player);
void end(double moves);

Answer 1

In addition to everything mentioned in Toby Speight's review:

This program can use at least one additional class and probably more. The class that is obviously missing is Game. The class Game should be responsible for loading the game from a file, saving the game to a file and executing the game.

The function createOriginalSave() should probably be broken up into createNewGame() and then use the save() function to save the new game.

The suggested createNewGame() function should generate a map of rooms.

Each room should be responsible for printing its data to the output file.

Most of the functions in the file that contains main are too 'complex' and need to be broken up into smaller functions. You might find some reusable code this way. The code is currently very difficult to maintain and expand because it is so complex.

Answer 2

<bits/stdc++.h> is not a standard C++ header. Please use only standard headers, so your code is portable.

using namespace std; is a terrible idea - it completely removes the benefit of namespaces, meaning that all the standard library (including future types and functions not yet standardised) is mixed in with your program identifiers. Don't do that! Especially not in a header, where the harm is inflicted on every translation unit that includes that header.

There's sometimes an argument for importing a few, specific names into a smaller scope (a function, usually), but seldom for bringing in an entire namespace at the top level.

---

Many members are missing their const qualification. For example:

std::string getName() const;
//                    ^^^^^
// function must not modify 'this' object

---

Picking on a random function that just caught my eye:

void Rooms::setName(std::string nm) {
    name = nm;
}

We're making an unnecessary copy; we can avoid doing so:

void Rooms::setName(std::string nm) {
    name = std::move(nm);
}

And in Rooms::removeItem, we don't need a copy:

void Rooms::removeItem(const string& nm) {

There are many more functions that unnecessary copy their arguments.

Answer 3

In general when there is multiple options on a program like yours (on the section you manage the variable input), is desirable to make it more readable in order to avoid the multiples if statements. My recommendation is to use a map, or unordered_map with the input as first parameter and second a callback to the desire functionality. For example:

for (int i = 0; true; i++){

    cin >> input;
    Coord newPlayerCoords;

    transform(input.begin(), input.end(), input.begin(), ::tolower);

    if (input == "north") input = "n";
    else if (input == "south") input = "s";
    else if (input == "east") input = "e";
    else if (input == "west") input = "w";
    else if (input == "u") input = "up";
    else if (input == "d") input = "down";

Transform on

for (int i = 0; true; ++i){ // Check the increment here

    cin >> input;
    Coord newPlayerCoords;

    transform(input.begin(), input.end(), input.begin(), ::tolower);

    auto it = callbacks.find(input);
    if (it != callbacks.end()) {
        auto operation = it->second;

        operation(...);
     }

Hope you get the idea, just need to define statically the callbacks as your convenience.
