Entity Component System

Heavily based in Austin Morlan's ECS.

Usage instructions:

1. Create a Manager object. It will automatically create the other sub-managers: ComponentManager, EntityManager and SystemManager.

kuge::ECS::Manager manager {};

2. Register your Systems:

manager.registerSystem<PhysicsSystem>();
manager.registerSystem<RenderSystem>();

3. Register your Components:

manager.registerComponent<Transform>();
manager.registerComponent<RigidBody>();

4. Generate a signature for each of your Systems. The signature is a std::bitfield that informs which Components needs a System to perform it's task. For example:

kuge::ECS::Signature signature {};
signature.set(manager.componentID<Gravity>(), true);
signature.set(manager.componentID<Transform>(), true);
signature.set(manager.componentID<RigidBody>(), true);
manager.setSystemSignature<PhysicsSystem>(signature);

Pro tip: use Manager's systemSignature<T>() to retrieve a System's signature.

5. Create some entities:

auto entity {manager.createEntity()};

6. Add the desired Components to your Entities :

manager.addComponent(entity, Transform{});

7. On your update loop update() the Systems:

manager.system<PhysicsSystem>()->update();

8. Hopefully enjoy!
