update()

void Flint::AssetManager::update

(

)

Poll for hot-reload changes and fire pending callbacks.

Must be called once per frame (or at any other regular interval). When hot-reload is disabled, this is a no-op. Internally, the method checks elapsed time against HOT_RELOAD_INTERVAL and PENDING_RELOAD_INTERVAL to debounce rapid file-save events.

A texture whose reload fails to read or decode keeps its previous contents and is retried on the next revision change. An asset whose revision drops to 0 is logged once as missing, and its cached copy is kept until it reappears.
