^Type | [[Topic]] |
^Payload | [[ValueMessage]]<float> |
^Broadcaster | [[ISceneLoadingService]] |

This topic is broadcast from the [[ISceneLoadingService]] when as scene of a [[Chunk]] loads. The ValueMessage<float> carries the normalized progress of the loading operation, ranging from 0.0 to 1.0. Since [[ISceneLoadingService]] is implemented by each individual game engine differently, frequency of the updates or even the broadcast itself is highly dependent on the implementation details of the engine. The Unity module provided for this architecture uses the scene's loading [[https://docs.unity3d.com/6000.3/Documentation/ScriptReference/AsyncOperation-progress.html|AsyncOperation.progress]] as a returned value. Other implementors might use different metrics, or might not broadcast at all if a scene's loading progress cannot be tracked.
