General / "Unknown CMake command 'build_chapter'"

« on: February 06, 2022, 05:42:18 pm »

I'm trying to compile the example project files that came with the SFML Game Development book (the one with the ocean and rock on the cover). I'm using Visual Studio 2022. I went to "Open CMake" and ran the CMakeLists that was in the project directory and got an error on Line 6:

Code: [Select]

CMake Error at G:\[Name]\Documents\Packt\SFML Game Development\01_Intro\Source\CMakeLists.txt:6 (build_chapter): Unknown CMake command "build_chapter".

What am I doing wrong?

Graphics / Exception when trying to draw text from a function

« on: May 04, 2019, 08:07:18 pm »

Hi,

So I'm trying to get started on a new game. I figured that I could streamline the action of rendering text by putting all of the routines needed to do it (setting the font, the size, the color, and the text itself) into a function but when I try to execute this function, I get the error "Exception thrown at 0x0FD2485F (sfml-graphics-d-2.dll) in SFMLProject.exe: 0xC0000005: Access violation reading location 0x3F800004."

Here is my code:

#include <SFML/Graphics.hpp>

sf::Text drawText(sf::Font font, std::string inputText, int size, sf::Color color) //Function to draw text (TODO: Add the ability to specify coordinates)
{
        sf::Text outputText;
        outputText.setFont(font);
        outputText.setString(inputText);
        outputText.setCharacterSize(size);
        outputText.setFillColor(color);
        return outputText;
}

int main()
{
        sf::RenderWindow window(sf::VideoMode(200, 200), "SFML Project");
        sf::CircleShape shape(100.f);
        sf::Font testFont;
        testFont.loadFromFile("calibri.ttf");

        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.draw(drawText(testFont, "Development Build 0", 12, sf::Color::White));
                window.display();
        }

        return 0;
}

EDIT: I just want to add that this does not happen when I manually draw text in the main function.
