Jazz2::Actors::Collectibles::CollectibleBase::IlluminateLights class

#include <Jazz2/Actors/Collectibles/CollectibleBase.h>

Swarm of lights orbiting an illuminated collectible.

The effect is decoration, seeded at random and animated on its own, which is why it's reusable: an illuminated collectible in an online session is drawn by a stand-in that runs none of the object's logic, and reproducing the swarm there costs nothing — whereas describing two dozen constantly moving lights to every client on every update would be by far the most expensive object in the level.

Public functions

void Create()

Seeds the swarm.

auto IsEmpty() const -> bool

Returns true if the swarm hasn't been seeded yet.

void OnUpdate(float timeMult)

Advances the swarm.

void OnEmitLights(SmallVectorImpl<LightEmitter>& lights, Vector2f pos) const

Emits the swarm around the specified position.
