Scene Graph Verse Component

Want a torch that glows, an NPC that patrols, a platform that blinks? In Scene Graph, that behavior is a component — a little class you attach to an entity.

Think of the component as a blueprint. You write the behavior once, then stamp it onto any entity that needs it — each entity runs its own copy of the same logic.

We declare 'glow_component' from 'component' with final_super, so it can attach to entities. Inside OnBeginSimulation we use Entity — the entity this copy lives on — call GetComponent to grab its sound component, and Play it. Same class, different entity each time.

A component is your logic wearing an entity. Write it once, attach it anywhere.

glow_component := class<final_super>(component):
    OnBeginSimulation<override>():void =
        if (Light := Entity.GetComponent[sound_component]):
            Light.Play()
