blah

A small 2D C++ Game Framework, using few dependencies and simple code to maintain easy building and portability.

☆ This will likely see breaking changes! Use at your own risk! ☆

a sample application

#include <blah.h>
using namespace Blah;

Batch batch;

int main()
{
    Config config;
    config.name = "blah app";
    config.on_render = []()
    {
        App::backbuffer()->clear(Color::black);

        auto center = App::get_backbuffer_size() / 2;
        auto rotation = Time::seconds * Calc::TAU;
        auto transform = Mat3x2f::create_transform(center, Vec2f::zero, Vec2f::one, rotation);

        batch.push_matrix(transform);
        batch.rect(Rectf(-32, -32, 64, 64), Color::red);
        batch.pop_matrix();

        batch.render();
        batch.clear();
    };

    App::run(&config);
    return 0;
}

building

• Requires C++17 and CMake 3.14+
• A single Platform implementation must be enabled in CMake:
  • SDL2 (Default) BLAH_PLATFORM_SDL2
  • WIN32 (Unfinished) BLAH_PLATFORM_WIN32
  • Additional platforms can be added by implementing the Platform Backend
• At least one Renderer implementation must be enabled in CMake:
  • OpenGL (Default on Linux/macOS) BLAH_RENDERER_OPENGL
  • D3D11 (Default on Windows) BLAH_RENDERER_D3D11
  • Additional renderers can be added by implementing the Renderer Backend

notes

• There's no Shader abstraction, so you need to swap between GLSL/HLSL depending on the Renderer.
• Only floatN/mat3x2/mat4x4 uniforms are supported.
• There's no Audio API or backend implementation yet.
• No threaded rendering so it will explode if you try that.
