Description​

System that propagates score snapshots to ScoreObserverComponents.

Each frame, queries all active entities with a ScoreObserverComponent and updates them with the current ScorePoolSnapshot from the ScorePoolManager. The component's revision-based change detection ensures that downstream consumers (e.g. UI bindings) are only notified when the score actually changes.

ScoreObserverSystem()​

helios::engine::mechanics::scoring::systems::ScoreObserverSystem::ScoreObserverSystem (ScorePoolManager & scorePoolManager)
 inline explicit

Constructs the system with a reference to the ScorePoolManager.

Parameters
scorePoolManager

The ScorePoolManager providing score pool state.

Public Member Functions​

update()​

void helios::engine::mechanics::scoring::systems::ScoreObserverSystem::update (helios::engine::runtime::world::UpdateContext & updateContext)
 inline noexcept

Updates all active ScoreObserverComponents with current score data.

Compares each observer's cached revision against the pool's current revision. On mismatch, propagates the pool's snapshot to the component.

Parameters
updateContext

The current frame's update context.
