SFML 窗口大小调整非常难看 [英] SFML Window Resizing is very ugly

问题描述

当我调整我的 sfml 窗口的大小时，当我削减 resize 以使其更小并调整其大小以使其更大时，它会给你一个非常奇怪的效果.

When I resize my sfml window, when I cut resize to make it smaller and resize to make it larger, it gives you a really weird effect.

如何使调整大小更漂亮?代码来自 code::blocks 的安装教程.代码(同sfml网站code::blocks安装教程中的代码):

How do I make the resizing more prettier? The code is from the installation tutorial for code::blocks. Code (same as the code in the installation tutorial for code::blocks on the sfml website):

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

推荐答案

您需要管理窗口的大小调整.否则坐标不对.这是带有解决方案的代码的摘录.感谢这篇论坛帖子的作者，这是我在寻找解决方案时曾经找到的地方:https://en.sfml-dev.org/forums/index.php?topic=17747.0

You need to manage the resize of the window. Otherwise the coordinates are wrong. Here is an excerpt of your code with the solution. Credits go to the author of this forum post, this is where I once found it when I was looking for a solution: https://en.sfml-dev.org/forums/index.php?topic=17747.0

此外，您可以根据新尺寸设置新坐标.该链接为您提供了更多信息.

Additionally you can set the new coordinates based on the new size. The link gives you more information.

// create own view
sf::View view = window.getDefaultView();

while (window.isOpen())
{
    sf::Event event;
    while (window.pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
            window.close();

        if (event.type == sf::Event::Resized) {
            // resize my view
            view.setSize({
                    static_cast<float>(event.size.width),
                    static_cast<float>(event.size.height)
            });
            window.setView(view);
            // and align shape
        }
    }
