Question

我一直在设计我的c ++控制台游戏，我对游戏循环有疑问。每当游戏循环时，我最终会在构造函数中重新初始化我的速度变量，这会将它们设置为＆＃34; 0＆＃34;。我有几个关于如何解决这个问题的想法，但它最终破坏了我的游戏基础设施，并在一段时间后让人感到困惑。有人可以告诉我如何防止我的速度变量重新初始化。顺便说一下，我将在稍后了解如何更好地对标题进行分组。

FPS.timerMilli(1)是一个在退出函数前计算1毫秒的函数。（试图控制FPS）。

rectangle.cpp：

#include "stdafx.h"
#include <iostream>
#include <Windows.h>

#include "rectangle.h"


void rectangle::rectangleDrawPos(int h, int k) {

    // Draw top of rectangle
    for (int verticle = 1; verticle <= h; verticle += 1) {
        std::cout << "\n";
    }

    for (int horizontal = 1; horizontal <= h; horizontal += 1) {
        std::cout << " ";
    }
    for (int x = 1; x <= width; x += 1) {
        std::cout << ".";
    }
    std::cout << "\n";

    //Number of sides
    midWidth = width - 2;
    for (int y = 1; y <= height; y+=1) {

    //Draw sides
        for (int x = 1; x <= h; x += 1) {
            std::cout << " ";
        }

        std::cout << ":";
        for (int x = 1; x <= midWidth; x+=1) {
            std::cout << " ";
        }
        std::cout << ":\n";
    }

    //Bottom of rectangle
    for (int x = 1; x <= h; x += 1) {
        std::cout << " ";
    }
    for (int x = 1; x <= width; x += 1) {
        std::cout << ".";
    }
    std::cout << "\n";
}

如果你需要你的变量保留它的值，你可以把它们变成静态变量。

游戏基础设施无法正常工作（c ++）
