Detailed Description

Tags a GameObject as a point light source in the scene.

When a GameObject has a LightComponent, Scene::CollectLight() picks it up during the per-frame traversal and adds a LightData entry (world position

• RGB colour) to the list forwarded to RenderQueue::Draw(). The queue then uploads the light data as uniforms to every material that is drawn.

Usage

auto *lightObj = scene->CreateObject("SunLight");
lightObj->SetPosition(vec3(10, 20, 5));
auto *light = new LightComponent();
light->SetColor(vec3(1.0f, 0.95f, 0.8f));   // warm white
lightObj->AddComponent(light);

Note

Only the owner's world position is used — there is no direction, radius, or attenuation yet (point light model).
