laggy输出到控制台

我一直在试图在控制台中制作小行星，我知道控制台不是这样做的理想方式，但我想挑战自己。

我遇到的问题是打印到屏幕上。首先，我的屏幕正在闪烁，因为我没有更新某些屏幕零件，而是通过将整个数组附加到字符串并输出该字符串来重新绘制每个帧。

因此，我更改了代码来做到这一点，但是现在我目前的问题是我的游戏FPS确实很低，因为我无法将其称为一个COUT功能。

要将我的代码打印到屏幕上，我有一个宽度和高度作为大小的2D字符。然后，我将数组复制，更改输出并将其与先前的输出进行比较，以查看是否需要更改像素，然后将其更改。

这是我的绘制功能

void draw() {
    char prevOutput[ArrayBorder][ArrayBorder];
    copyOutput(outputBuffer, prevOutput);
    innitOutput();
    plotPolygons();
    for (int y = 0; y < GameBorder; y++) {
        for (int x = 0; x < GameBorder; x++) {
            if (outputBuffer[x][y] == prevOutput[x][y]) {continue;}
            setCursorPosition(x, y);
            cout << outputBuffer[x][y];
        }
    }
    cout.flush();
}

，这是我以前的绘制功能

void draw() {
    innitOutput();
    plotPolygons();
    system("CLS");
    string output = "";
    for (int y = 0; y < GameBorder; y++) {
        for (int x = 0; x < GameBorder; x++) {
            output += outputBuffer[x][y];
        }
        output += "\n";
    }
    cout << output;
}

原文

I have been trying to make asteroids in the console, I know that the console isn't an ideal way to do this, but I wanted to challenge myself.

The problem I am having is with printing to the screen. At first, my screen was flickering because I wasn't updating certain screen parts and instead redrawing every frame by appending the whole array to a string and outputting that string.

So I changed my code to do that, but my current problem now is that the fps of my game is really low because I can't batch call it to one cout function.

To print my code to the screen I have a 2d array of characters with width and height as its size. Then I copy the array, change the output, and compare it to the previous output to see if the pixel needs to be changed, then change it.

Here is my draw function

void draw() {
    char prevOutput[ArrayBorder][ArrayBorder];
    copyOutput(outputBuffer, prevOutput);
    innitOutput();
    plotPolygons();
    for (int y = 0; y < GameBorder; y++) {
        for (int x = 0; x < GameBorder; x++) {
            if (outputBuffer[x][y] == prevOutput[x][y]) {continue;}
            setCursorPosition(x, y);
            cout << outputBuffer[x][y];
        }
    }
    cout.flush();
}

Here is my previous draw function

void draw() {
    innitOutput();
    plotPolygons();
    system("CLS");
    string output = "";
    for (int y = 0; y < GameBorder; y++) {
        for (int x = 0; x < GameBorder; x++) {
            output += outputBuffer[x][y];
        }
        output += "\n";
    }
    cout << output;
}
