Question

我正在使用Tic-Tac-Toe SFML C ++ [STATE CREATION]教程中Sonar Systems提供的相同代码制作Tic-Tac-Toe游戏。但是游戏无法运行，相反，我收到一个消息框，指出调试断言失败，并且在输出窗口中引发了异常：无法超出范围的deque迭代器，并且（有时并非总是）当我尝试再次运行它时输出窗口中会显示以下附加消息：“无效参数已传递给认为无效参数致命的函数”

我安装了sfml并将其成功链接到我的VS2017项目，项目文件中的主体包含了所有必需的资源，并且我确保所有目录路径都正确。我修复了最初的86个错误（关于其他头文件），并且此刻没有红色下划线显示任何代码，只是出现了此消息框。

这是导致相同问题的最少代码：

main.cpp

#include "pch.h"
#include <iostream>
#include "Game.h"

int main()
{
    TicTacToe::Game(800, 600, "Tic-Tac-Toe Game");
    return EXIT_SUCCESS;
}

Game.cpp

#include "pch.h"
#include "Game.h"

namespace TicTacToe
{
    Game::Game(int width, int height, std::string title)
    {
        _data->window.create(sf::VideoMode(width, height), title, sf::Style::Close | sf::Style::Titlebar);

        this->Run();
    }

    void Game::Run()
    {
        float newTime, frameTime, interpolation;
        float currentTime = this->_clock.getElapsedTime().asSeconds();
        float accumulator = 0.0f;
        while (this->_data->window.isOpen())
        {
            this->_data->machine.ProcessStateChanges();
            newTime = this->_clock.getElapsedTime().asSeconds();
            frameTime = newTime - currentTime;

            if (frameTime > 0.25f)
            {
                frameTime = 0.25f;
            }

            currentTime = newTime;
            accumulator += frameTime;

            while (accumulator >= dt)
            {
                this->_data->machine.GetActiveState()->HandleInput();
                this->_data->machine.GetActiveState()->Update(dt);

                accumulator -= dt;
            }

            interpolation = accumulator / dt;
            this->_data->machine.GetActiveState()->Draw(interpolation);
        }
    }
}

        virtual void Draw(float dt) = 0;
        virtual void Pause() { }
        virtual void Resume() { }


    };
}

在调用堆栈窗口中，这些是崩溃的行：

StateMachine.cpp（第53-56行）

StateRef &StateMachine::GetActiveState()
    {
        return this->_states.top();
    }

Game.cpp（第41行）

this->_data->machine.GetActiveState()->Draw(interpolation);

Game.cpp（第6-11行）

Game::Game(int width, int height, std::string title)
    {
        _data->window.create(sf::VideoMode(width, height), title, sf::Style::Close | sf::Style::Titlebar);

            this->Run();
    }

main.cpp（第7行）

TicTacToe::Game(800, 600, "Tic-Tac-Toe Game");

我不知道这可能有什么用，但以防万一，我还进入输出窗口，无法找到或打开一些PDB文件，所以我尝试修复它并加载了其中的一些文件，但是仍然有些无法加载。

P.S。我是编程新手

如何修复调试断言失败？
