blah
A small 2D C++ Game Framework, using few dependencies and simple code to maintain easy building and portability.
β This will likely see breaking changes! Use at your own risk! β
a sample application
#include <blah.h>
using namespace Blah;
Batch batch;
int main()
{
Config config;
config.name = "blah app";
config.on_render = []()
{
auto target = App::backbuffer();
target->clear(Color::black);
auto center = Vec2f(target->width(), target->height()) / 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(target);
batch.clear();
};
return App::run(&config);
}
building
- Requires C++17 and CMake 3.14+
- 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
- OpenGL (Default on Linux/macOS)
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.
- No threaded rendering, so it will explode if you try that.
