Graphics / Render sf::Text in HD quality using sf::View

« on: May 14, 2022, 04:32:00 pm »

Hey!
I'm developing a co-op game and i need to draw nicknames with good quality of sf::Text. It's could be easier if the sf::View size was 1920x1080, but in my game it is 300x300.
I made a test project (https://github.com/JusticeShurup/ViewAndTextTest)

main.cpp

(click to show/hide)

#include "Map/Map.h"
#include "Camera.h"
#include "TextureContainer/TextureContainer.h"
#include <iostream>

int main() {
        sf::RenderWindow window(sf::VideoMode(1920, 1080), "Test", sf::Style::Default);
        sf::Event event;
        Map map("Map\\Map.txt", "Map\\GameObjectsMap.txt");
        sf::Vector2f camera_pos(300, 300);
        sf::Vector2f camera_size(300, 300);
        Camera camera(camera_size, camera_pos, &window, sf::Vector2i(32 * map.getSize().x, 32 * map.getSize().y));
        bool is_active = true; 

        sf::Text nickname;
        nickname.setFont(TextureContainer::getInstance()->getFont());
        nickname.setCharacterSize(15);
        nickname.setString("nickname");
        nickname.setPosition(280, 280);


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

                camera.update();
                window.setView(*camera.getView());

                window.clear();
                window.draw(map);
                window.draw(nickname);
                window.display();
        }

        return 0;
}

result:

As you can see the quality leaves much to be desired.

We can resize current sf::View to 1920x1080 and after resize to 300x300.
code:

(click to show/hide)

camera.setSize(1920, 1080);
window.draw(nickname);
camera.setSize(300, 300);

result

(click to show/hide)

Everything would be fine if not for one problem. This nickname moves, when you move camera and i don't know why.

This happens without assigning a position to a nick. I can assign a position to a nickname, but that won't solve the other problem, which is that I won't be able to add other players' nicknames, as they will be in the wrong places.

Is it possible to display text in HD quality and still have it's actual size?
