C++ problems in creating the .h file of an already existing code

Lyt · Jul 22, 2022

Hi, I'm making a little game for a college project.
I was asked by the professor to implement a pathfinding system. He also recommended a site to get the code from https://www.redblobgames.com/pathfinding/a-star/implementation.html. So I took the code, adapted it, translated the comments into Italian (my language) and split it into two files AStar.cpp and Map.cpp. The problem is that in order for the code to work I need to create the respective .h files. I have been trying for several days but still have problems. Would anyone know how to give me a hand? it's my first time working on someone else's code.

this is the Map.cpp file

C++:

#include "librerie.h"

//Crea un tipo di dato GridLocation, che contiene la posizione sulla scacchiera
struct GridLocation {
    int x, y;
};

namespace std {
    //implementare la funzione hash in modo da poter inserire GridLocation in un unordered_set

    //I unordered_set sono contenitori che memorizzano elementi univoci in nessun ordine particolare
    // e che consentono il recupero rapido di singoli elementi in base al loro valore.
    template <> struct hash<GridLocation> {
        std::size_t operator()(const GridLocation& id) const noexcept {
            // NOTE: better to use something like boost hash_combine
            return std::hash<int>()(id.x ^ (id.y << 16));
        }
    };
}



struct SquareGrid {
    static std::array<GridLocation, 4> DIRS;

    int width, height;
    std::unordered_set<GridLocation> walls;

    SquareGrid(int width_, int height_)
            : width(width_), height(height_) {}

    bool in_bounds(GridLocation id) const {
        return 0 <= id.x && id.x < width
               && 0 <= id.y && id.y < height;
    }

    bool passable(GridLocation id) const {
        return walls.find(id) == walls.end();
    }

    std::vector<GridLocation> neighbors(GridLocation id) const {
        std::vector<GridLocation> results;

        for (GridLocation dir : DIRS) {
            GridLocation next{id.x + dir.x, id.y + dir.y};
            if (in_bounds(next) && passable(next)) {
                results.push_back(next);
            }
        }

        if ((id.x + id.y) % 2 == 0) {
            // see "Ugly paths" section for an explanation:
            std::reverse(results.begin(), results.end());
        }

        return results;
    }
};

Here it gives me error to "find ()". But it only started after the CLion update, I don't understand why.
Thanks in advance everyone, and sorry if I made some grammatical errors, as I mentioned this is not my mother tongue

Sorry for the text walls, but I don't think the problem is in a specific spot, so I didn't know what to share. In addition, the comment to the code remained in Italian, sorry for that

The libraries used (saved in the Librerie.cpp file) are:

C++:

#include <iostream>
#include <time.h>
#include <ctime>
#include <cstdlib>
#include <iomanip>

Hello there, @Lyt.

Despite my rusty C skills, I'll do my best to help. But first, could you perhaps share some of the errors you're getting? I've had a lot of problems with .c/.h files and trying to get them to work together in the past, but that is because I keep including all of the headers in the .c files and when I go to include them in another .c file, it begins causing errors and I often have to create one big .h file just to avoid the issue as best I can. Any error codes or other possible solutions you've tried and their results would be handy to know.

Thank you.

yes
From last post I made some changes to the code. I essentially moved a few things between Map.h and Map.cpp. Now Clion no longer marks me any errors. But...

I honestly don't understand what's going on
When I select the error code on CLion, CLion warns me of the error by saying: Variable has incomplete type 'SquareGrid'

I hope I was clearer, thanks anyway in advance

When I select the error code on CLion, CLion warns me of the error by saying: Variable has incomplete type 'SquareGrid'

I don't know what would cause this. I've looked over the Map.* files to see if there is an error there and from my knowledge of C(not C++) it looks to have been declared and initialised correctly, so I don't see what the error could be there. It isn't exactly good practice but whenever I had problems with multiple header and .c files, I'd end up resorting to this quick hack that would work but doesn't exactly make for good code:

Import header in file1.c.
Import file1.c(not file1.h) into file2.c.

From my memory, this typically resolved some of the common and extremely annoying errors I faced with headers, but as I said, it isn't good practice and I highly recommend against doing it. I say it isn't good because I have yet to see an open-source project with serious programming going on to import the .c with the .h inside, rather than just directly including the .h.

Can I just check as well that you're importing the Map.h into TurnSystem.cpp and not Map.c?

Side-note: If you've done well and did not follow the quick hack that I done(again, please avoid from doing it if you want an easier life because it will most likely give you headaches later on), I found through a quick search this post on a C++ programming forum[/URL]. To save you clicking the link, two users responded to the OP's question with the following:

You need to give your 'sales' struct a body.
(code example)

To which another responded:

He did. In SalesNmSpce.cpp.

That's the problem. You need to do it within your header. In main.cpp the compiler doesn't know what SALES::sales is (it's only a forward declaration).

All the functions in SalesNmSpce.h act like member functions of sales. So why don't you turn in into a class with OOP?

My suggestion then, based on the second user's post in that thread, is to initialise your structure's members in the header rather than the C++ file. Try that and let me know how it goes.

Short update: talking to some of my classmates, I noticed how the code I got from the internet as a starting point is rather long and complicated. I found another one that should be simpler. Unfortunately, the .h file is also missing from this, I have created a second project on CLion, tomorrow I will try to create the .h file and if it works I replace it with the old one. the new code is:

C++:

// A C++ Program to implement A* Search Algorithm
#include <bits/stdc++.h>
using namespace std;

#define ROW 9
#define COL 10

// Creating a shortcut for int, int pair type
typedef pair<int, int> Pair;

// Creating a shortcut for pair<int, pair<int, int>> type
typedef pair<double, pair<int, int> > pPair;

// A structure to hold the necessary parameters
struct cell {
    // Row and Column index of its parent
    // Note that 0 <= i <= ROW-1 & 0 <= j <= COL-1
    int parent_i, parent_j;
    // f = g + h
    double f, g, h;
};

// A Utility Function to check whether given cell (row, col)
// is a valid cell or not.
bool isValid(int row, int col)
{
    // Returns true if row number and column number
    // is in range
    return (row >= 0) && (row < ROW) && (col >= 0)
           && (col < COL);
}

// A Utility Function to check whether the given cell is
// blocked or not
bool isUnBlocked(int grid[][COL], int row, int col)
{
    // Returns true if the cell is not blocked else false
    if (grid[row][col] == 1)
        return (true);
    else
        return (false);
}

// A Utility Function to check whether destination cell has
// been reached or not
bool isDestination(int row, int col, Pair dest)
{
    if (row == dest.first && col == dest.second)
        return (true);
    else
        return (false);
}

// A Utility Function to calculate the 'h' heuristics.
double calculateHValue(int row, int col, Pair dest)
{
    // Return using the distance formula
    return ((double)sqrt(
            (row - dest.first) * (row - dest.first)
            + (col - dest.second) * (col - dest.second)));
}

// A Utility Function to trace the path from the source
// to destination

    printf("\nThe Path is ");
    int row = dest.first;

        pair<int, int> p = Path.top();
        Path.pop();

    // there is no way to destination cell (due to
    // blockages)
    if (foundDest == false)
        printf("Failed to find the Destination Cell\n");

    return;
}

Main.cpp

C++:

#include "Code.h"
// Driver program to test above function
int main()
{
    /* Description of the Grid-
    1--> The cell is not blocked
    0--> The cell is blocked */
    int grid[ROW][COL]
            = { { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 0, 1, 1, 1, 1 },
                { 1, 0, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
                { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 } };

    grid[2][0]=0;

    // Source is the left-most bottom-most corner
    Pair src = make_pair(8, 0);

    // Destination is the left-most top-most corner
    Pair dest = make_pair(0, 0);

    aStarSearch(grid, src, dest);

    return (0);
}

thanks again for the help
