Gamedev Framework (gf)

Gamedev Framework (gf) is a framework to build 2D games in C++14. It is based on SDL and OpenGL ES 2.0, and presents an API that is very similar to the graphics module of SFML with additional features. It is not a game engine, it is more something like a framework, similar to libGDX in the Java world.

Gamedev Framework (gf) is licensed under the terms and conditions of the zlib/libpng license.

Quick example

#include <gf/Event.h>
#include <gf/Font.h>
#include <gf/RenderWindow.h>
#include <gf/Sprite.h>
#include <gf/Text.h>
#include <gf/Window.h>

int main() {
  // Create the main window and the renderer
  gf::Window window("Example", { 640, 480 });
  gf::RenderWindow renderer(window);

  // Load a sprite to display

  gf::Texture texture;

  if (!texture.loadFromFile("sprite.png")) {
    return EXIT_FAILURE;
  }

  gf::Sprite sprite(texture);
  sprite.setPosition({ 300, 200 });

  // Create a graphical text to display

  gf::Font font;

  if (!font.loadFromFile("DroidSans.ttf")) {
    return EXIT_FAILURE;
  }

  gf::Text text("Hello gf!", font, 50);
  text.setPosition({ 100, 100 });

  renderer.clear(gf::Color::White);

  // Start the game loop

  while (window.isOpen()) {
    // Process events

    gf::Event event;

    while (window.pollEvent(event)) {
      switch (event.type) {
        case gf::EventType::Closed:
          window.close();
          break;
        default:
          break;
      }
    }

    // Draw the entities

    renderer.clear();
    renderer.draw(sprite);
    renderer.draw(text);
    renderer.display();
  }

  return 0;
}
