A minimal C++ toolset for 2D games using SDL2 + OpenGL.
This is just a snippet showing how to draw a sprite to the screen at a position {50.0f, 150.0f}:
#include <auk.h>
using namespace auk;
int main(int argc, char *argv[]) {
int screen_w = 512, screen_h = 256;
SDL_Window * window = Window::init("Window Title", screen_w, screen_h);
Mat4x4 window_projection = LinAlg::ortho(0, (float) screen_w, (float) screen_h, 0, -1, 1);
BatchRenderer renderer;
renderer.setup();
Shader shader = Shader::default_sprite_shaders();
shader.use().set_mat4x4("projection", window_projection);
Texture sprite_tex = Texture::from_file("sprite.png");
SDL_Event event;
bool quit = false;
while(!quit) {
while (SDL_PollEvent(&event) != 0) if (event.type == SDL_QUIT) quit = true;
Graphics::viewport(screen_w, screen_h);
Graphics::clear(Color::black);
renderer.set_texture(&sprite_tex);
renderer.draw_tex({50.0f, 150.0f});
renderer.render();
SDL_GL_SwapWindow(window);
}
return 0;
}
It requires CMake 3.14+ to build. This is a minimal example of a CMakeLists.txt file to build something:
cmake_minimum_required(VERSION 3.11)
project(example)
# C++ version
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_subdirectory(path/to/auk)
add_executable(example main.cpp)
target_link_libraries(example auk)CMake will download automatically SDL2 and it will be built and linked statically to the application.
