使用 sfml 更新 TicTacToe 游戏中的图块

Question

因此，我正在使用 C++ 中的 sfml 创建游戏，但我的代码没有更新我正确单击的图块。

我使用函数 isTileClicked 来检查图块是否被单击，并将变量 clickedTileRow 和 clickedTileCol 更新为当前单击的图块的行和列。我希望它只更新索引与变量 clickedTileRow 和 clickedTileCol 一致的图块。这里的问题是，当我单击新图块时，它也会更新所有以前单击的图块。

game.h 文件是：

#include <iostream>
#include <SFML/Graphics.hpp>
#ifndef GAME_H
#define GAME_H
static int changer = 0;
class Player; 
class Game  //class to playGame
    {
        private:
        sf :: RenderWindow window;
        sf :: Texture Tex, emptyTile; 
        sf :: Sprite **sprites;
        sf :: Event clickSprite;
        int clickedTileRow, clickedTileCol;
        Player *p;

        public:
        Game(); 
        ~Game();
        sf:: Window& getWindow();
        void setSpriteMemory();
        sf :: Sprite** getSpritesArr();
        void setTexture();
        sf::Texture getTexture();
