Question

好，所以我正在为一个课堂项目做游戏，我有两个文件：game.cpp和一个game.h。我声明了所有私有变量和公共函数，目前正在.cpp文件中对其进行定义。

在菜单功能中，我有以下开关：

switch (option) {
case 1:

    while (this->playing) {
        //clean screen
        h.screen();

        //deletescroll bar
        h.nosc();

        //draw canvas
        h.draw();


    } 
}

这是我的draw函数：

void Game::draw() {
    HWND window= GetConsoleWindow();

    MoveWindow(window, 400, 100, 750, 550, TRUE);
    Game h;



    GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);
    this->columns = csbi.srWindow.Right - csbi.srWindow.Left + 1;
    this->rows = csbi.srWindow.Bottom - csbi.srWindow.Top + 1;

    h.nosc();

    CONSOLE_SCREEN_BUFFER_INFO csbi;

    GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);
    this->columns = csbi.srWindow.Right - csbi.srWindow.Left + 1;
    this->rows= csbi.srWindow.Bottom - csbi.srWindow.Top + 1;*/

    gotoxy(15, 0);
    cout << "Lives: " << lives;

    gotoxy(45, 0);
    cout << "Level: " << this->level;

    gotoxy(75, 0);
    cout << "Score: " << this->score;

    //up - down
    for (int i = 2; i < this->columns - 1; i++) {

        gotoxy(i, 1);
        printf("%c", 205);
        //down
        gotoxy(i, this->rows - 1);
        printf("%c", 205);
    }

    //left - right
    for (int j = 2; j < this->rows - 1; j++) {
        gotoxy(2, j);
        printf("%c", 186);
        gotoxy(this->columns - 1, j);
        printf("%c", 186);
    }


    gotoxy(2, 1); 
    printf("%c", 201);
    gotoxy(2, this->rows - 1); 
    printf("%c", 200);
    gotoxy(this->columns - 1, 1);
    printf("%c", 187);
    gotoxy(columns - 1, rows - 1);
    printf("%c", 188);

    this->playing = false;
}

它应该返回到开关，并且由于playing现在为假，因此它不应再次运行，对吗？但是它仍在继续，我不确定该怎么办。这是我的头文件(.h)：

#pragma once

#include<Windows.h>
#include <iostream>
#include <conio.h>

using namespace std;

class Game {

private:
    int xAxis= 25;
    int yAxis = 25;
    int direction = 0;
    int columns = 0;
    int rows = 0;
    int lives = 3;
    int level = 1;
    int score = 0;
    int scoreArr[9];    
    bool playing;

private:

我知道这段代码对于某些人来说似乎是一团糟，但我仍在学习。非常感谢您的帮助。

目前尚不清楚'h'对象到底是什么，但是public async Task RouteAsync(RouteContext context) { var requestPath = context.HttpContext.Request.Path.Value; if (!string.IsNullOrEmpty(requestPath) && requestPath[0] == '/') { // Trim the leading slash requestPath = requestPath.Substring(1); } // Get the page that matches. var page = GetPageList() .Where(x => x.VirtualPath.Equals(requestPath)) .FirstOrDefault(); // If we got back a null value set, that means the URI did not match if (page == null) { return; } //Invoke MVC controller/action var oldRouteData = context.RouteData; var newRouteData = new RouteData(oldRouteData); newRouteData.Routers.Add(this.target); // TODO: You might want to use the page object (from the database) to // get both the controller and action, and possibly even an area. // Alternatively, you could create a route for each table and hard-code // this information. if (context.RouteData.Values["action"] == "fakeAction") newRouteData.Values["controller"] = "realController"; newRouteData.Values["action"] = "realAction"; // This will be the primary key of the database row. // It might be an integer or a GUID. newRouteData.Values["id"] = page.Id; try { context.RouteData = newRouteData; await this.target.RouteAsync(context); } finally { // Restore the original values to prevent polluting the route data. if (!context.IsHandled) { context.RouteData = oldRouteData; } } } app.UseMvc(routes => { routes.Routes.Add( new CustomRoute(routes.ServiceProvider.GetRequiredService<IMemoryCache>(), routes.DefaultHandler)); routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); });中的行this->playing = false;将访问h.draw内的playing的不同变量或不同实例菜单功能。如果您需要的是在完成while (this->playing)之后立即结束循环，那为什么还需要while循环呢？

假设您有一个名为h的对象，则可以像下面这样修改代码。您不应该在此检查播放变量。

while (h.playing) {
    //clean screen
    h.screen();

    //deletescroll bar
    h.nosc();

    //draw canvas
    h.draw();
}
