General / Can't create the sf::Drawable vector[error -1073741819]

« on: July 09, 2023, 03:53:48 pm »

Hello, everyone!
I'm the begginer in the using of SFML and there is an error, which i can't fix:

#include <SFML/Graphics.hpp>
#include <iostream>
#include <memory>
#include <vector>

std::vector<std::shared_ptr<sf::Drawable>> createDrawableVector() {
        std::vector<std::shared_ptr<sf::Drawable>> vec;

        std::shared_ptr<sf::Font> tahoma = std::make_shared<sf::Font>();
        if (!tahoma->loadFromFile("corbel.ttf")) {
                return vec;
        }

        auto text = std::make_shared<sf::Text>("Clicks", *tahoma, 20);
        text->setPosition(100.f, 100.f);
        vec.push_back(std::move(text));

        auto rect = std::make_shared<sf::RectangleShape>(sf::Vector2f(100.f, 100.f));
        rect->setPosition(200.f, 200.f);
        rect->setFillColor(sf::Color::Red);
        vec.push_back(std::move(rect));

        return vec;
}

int main() {
        sf::RenderWindow window(sf::VideoMode(550, 700), "SFML Drawable Vector", sf::Style::Close);

        std::vector<std::shared_ptr<sf::Drawable>> drawableVector = createDrawableVector();

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

                window.clear();

                for (auto &element : drawableVector) {
                        window.draw(*element);
                }

                window.display();
        }

        return 0;
}

When i'm running it i'm taking the -1073741819 error.

But when i'm replacing it into main() the error is going away

int main() {
        sf::RenderWindow window(sf::VideoMode(550, 700), "SFML Drawable Vector", sf::Style::Close);

        std::vector<std::shared_ptr<sf::Drawable>> vec;

        std::shared_ptr<sf::Font> tahoma = std::make_shared<sf::Font>();
        if (!tahoma->loadFromFile("corbel.ttf")) {
                return -1;
        }

        auto text = std::make_shared<sf::Text>("Clicks", *tahoma, 20);
        text->setPosition(100.f, 100.f);
        vec.push_back(std::move(text));

        auto rect = std::make_shared<sf::RectangleShape>(sf::Vector2f(100.f, 100.f));
        rect->setPosition(200.f, 200.f);
        rect->setFillColor(sf::Color::Red);
        vec.push_back(std::move(rect));

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

                window.clear();

                for (auto &element : vec) {
                        window.draw(*element);
                }

                window.display();
        }

        return 0;
}

The same code with sf::RectangleShape, not sf::Text is working great
I think, that some text data became null after createDrawableVector() was finished, therefore text can't be rendered.
Cuz this code is not working too

#include <SFML/Graphics.hpp>
#include <iostream>
#include <memory>
#include <vector>

std::vector<sf::Text> createDrawableVector() {
        std::vector<sf::Text> vec;

        sf::Font corbel;
        if (!corbel.loadFromFile("corbel.ttf")) {
                return vec;
        }

        sf::Text text("Clicks", corbel, 20);
        text.setPosition(100.f, 100.f);
        vec.push_back(text);

        return vec;
}

int main() {
        sf::RenderWindow window(sf::VideoMode(550, 700), "SFML Drawable Vector", sf::Style::Close);

        std::vector<sf::Text> drawableVector = createDrawableVector();

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

                window.clear();

                for (auto &element : drawableVector) {
                        window.draw(element);
                }

                window.display();
        }

        return 0;
}
 

Please help me with it)
