• Spatial audio system
• Scene management with transitions
• Live editor and debugging tools
• Cross-platform (Windows, Linux, macOS)
• Post-processing effects pipeline
• Particle system
• 2D lighting system
• Networking (TCP/UDP)

Quick Start

#include <Nebula/Engine.h>
using namespace nebula;

class MyGame : public Application {
public:
    MyGame() : Application("My Game", 1280, 720) {}

    void onInit() override {
        auto player = ecs::World::createEntity();
        ecs::World::addComponent<gfx::Sprite>(player, "hero.png");
        ecs::World::addComponent<Transform>(player, {640, 360});
    }

    void onUpdate(float dt) override {
        auto& t = ecs::World::getComponent<Transform>(player);
        if (Input::isKeyHeld(Key::Right)) t.position.x += 300 * dt;
        if (Input::isKeyHeld(Key::Left))  t.position.x -= 300 * dt;
    }

    void onRender() override {
        Renderer::begin(camera);
        Renderer::drawSprites();
        Renderer::end();
    }

    ecs::Entity player;
    gfx::Camera camera;
};

int main() {
    MyGame game;
    game.run();
}
