초보 개발자 지피티로 다양한 게임 만들어 보기 - 틱텍토

먼저 필자는 컴퓨터 공학과 학생이며 이러한 글을 쓰는 이유는 지피티같은 AI들이 우리의 돈벌이를 빼앗가 가기 때문에 그럴바에는 적극적으로 활용해 보면 어떨까라는 생각에서 시작하게 되었다.

 

 

 

 

 

 

 

먼저, 챗 지피티에게 틱텍토 게임을 c++로 만들어달라고 해보았더니

#include <iostream>

using namespace std;

const int SIZE = 3;
char board[SIZE][SIZE];
char currentPlayer = 'X';

void initializeBoard() {
    for (int i = 0; i < SIZE; ++i) {
        for (int j = 0; j < SIZE; ++j) {
            board[i][j] = ' ';
        }
    }
}

void printBoard() {
    for (int i = 0; i < SIZE; ++i) {
        for (int j = 0; j < SIZE; ++j) {
            cout << board[i][j];
            if (j < SIZE - 1) cout << " | ";
        }
        cout << endl;
        if (i < SIZE - 1) cout << "--|---|--" << endl;
    }
}

bool placeMarker(int row, int col) {
    if (row >= 0 && row < SIZE && col >= 0 && col < SIZE && board[row][col] == ' ') {
        board[row][col] = currentPlayer;
        return true;
    }
    return false;
}

bool checkWin() {
    // Check rows and columns
    for (int i = 0; i < SIZE; ++i) {
        if ((board[i][0] == currentPlayer && board[i][1] == currentPlayer && board[i][2] == currentPlayer) ||
            (board[0][i] == currentPlayer && board[1][i] == currentPlayer && board[2][i] == currentPlayer)) {
            return true;
        }
    }
    // Check diagonals
    if ((board[0][0] == currentPlayer && board[1][1] == currentPlayer && board[2][2] == currentPlayer) ||
        (board[0][2] == currentPlayer && board[1][1] == currentPlayer && board[2][0] == currentPlayer)) {
        return true;
    }
    return false;
}

bool checkDraw() {
    for (int i = 0; i < SIZE; ++i) {
        for (int j = 0; j < SIZE; ++j) {
            if (board[i][j] == ' ') return false;
        }
    }
    return true;
}

void switchPlayer() {
    currentPlayer = (currentPlayer == 'X') ? 'O' : 'X';
}

int main() {
    initializeBoard();
    bool gameEnded = false;

    while (!gameEnded) {
        printBoard();
        int row, col;
        cout << "Player " << currentPlayer << ", enter your move (row and column): ";
        cin >> row >> col;

        if (placeMarker(row - 1, col - 1)) {
            if (checkWin()) {
                printBoard();
                cout << "Player " << currentPlayer << " wins!" << endl;
                gameEnded = true;
            } else if (checkDraw()) {
                printBoard();
                cout << "The game is a draw!" << endl;
                gameEnded = true;
            } else {
                switchPlayer();
            }
        } else {
            cout << "This move is not valid" << endl;
        }
    }

    return 0;
}

다음과 같은 코드를 짜 주었다.

입력을 클릭으로 받고 싶어서 다시 한번 물어보니 

#include <SDL.h>
#include <iostream>

const int WINDOW_WIDTH = 600;
const int WINDOW_HEIGHT = 600;

        }
    }

    for (int i = 1; i < 3; ++i) {
        SDL_RenderDrawLine(renderer, i * CELL_SIZE, 0, i * CELL_SIZE, WINDOW_HEIGHT);

        }
    }
}

bool placeMarker(int row, int col) {

        if ((board[i][0] == currentPlayer && board[i][1] == currentPlayer && board[i][2] == currentPlayer) ||
            (board[0][i] == currentPlayer && board[1][i] == currentPlayer && board[2][i] == currentPlayer)) {
            return true;
        }
    }
    if ((board[0][0] == currentPlayer && board[1][1] == currentPlayer && board[2][2] == currentPlayer) ||

void switchPlayer() {
    currentPlayer = (currentPlayer == 'X') ? 'O' : 'X';
}

int main(int argc, char* argv[]) {
    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        std::cerr << "SDL could not initialize! SDL_Error: " << SDL_GetError() << std::endl;
        return 1;
    }

    SDL_Window* window = SDL_CreateWindow("Tic Tac Toe", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WINDOW_WIDTH, WINDOW_HEIGHT, SDL_WINDOW_SHOWN);
    if (window == nullptr) {
        std::cerr << "Window could not be created! SDL_Error: " << SDL_GetError() << std::endl;
        SDL_Quit();
        return 1;
    }

    SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
    if (renderer == nullptr) {

        SDL_DestroyWindow(window);
        SDL_Quit();
        return 1;
    }

    initializeBoard();
    bool quit = false;
    SDL_Event e;

    while (!quit) {
        while (SDL_PollEvent(&e) != 0) {
            if (e.type == SDL_QUIT) {
                quit = true;
            } else if (e.type == SDL_MOUSEBUTTONDOWN && !gameEnded) {
                int x, y;

                int row = y / CELL_SIZE;

                if (placeMarker(row, col)) {

                    }
                }
            }
        }

        SDL_SetRenderDrawColor(renderer, 255, 255, 255, SDL_ALPHA_OPAQUE);
        SDL_RenderClear(renderer);
        drawBoard(renderer);
        SDL_RenderPresent(renderer);
    }

    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}

이러한 코드를 금새 짜주었다.

인간이 짠다면 한참 걸릴 일을 챗 지피티를 활용하니 3분도 안되어 끝난걸 볼 수 있다. 지피티를 적극적으로 활용하여 1인 사업을 차리는 것이 목표이다.
