Lynx Engine

A simple (mostly) 2D game engine/framework written in C++ with Vulkan

✨ Features

• Layer system
• Macro based logging
• Event system
  • Non blocking event queue
  • Window events (WindowClose, WindowMove, WindowResize, WindowEnterFullscreen, WindowExitFullscreen, WindowEnterFocus, WindowExitFocus)
  • Keyboard events (KeyPressed, KeyReleased, KeyRepeat)
    • Custom keycodes (Compatible with SDL3)
  • Mouse events (MouseButtonPressed, MouseButtonReleased, MouseScroll, MouseMove)
• Timestep and Clock classes for framerate independent motion
• User input polling
  • SDL implementation
  • GLFW implementation
• Graphics
  • Window abstraction
  • SDL window implementation
  • GLFW window implementation
  • Perspective camera
  • Simple perspective camera controller with WASD movement + mouse rotation + scroll zoom (fov) + speed boost when holding shift
  • Orthographic camera
  • Rendering (Loosely based on my Vulkan learning repo)
• Resource management
• ECS
• Audio support

🚀 Getting started

#include <LynxEngine.h>

class MyLayer : public Lynx::Layer
{
  public:
    virtual void onAttach() override
    {
      LYNX_INFO("Hello World");
    }
};

int main()
{
  auto app = Lynx::Application();
  app.pushLayer<MyLayer>();
  app.run();
}
