I had never seen anything like this before. Seeing that is was supposed to be an insertable object, I tired Instance.new("AuroraScript", workspace) and got an error This type can not be instantiated. There is also AuroraService and AuroraScriptService. Finally, an Aurora Script has the following special properties:
Source : string
Priority : number
Tag : string
EnableLOD : boolean
RunInParallel : boolean
LODDistanceFactor : number
LODFrequencyFactor : number
Dump Mispredictions : boolean
I couldn’t find anything online about it. Is this a core feature or some lost idea?
Doing a further digging into AuroraService, makes me think that this will have something to do with physics. It would explain the predictions part of the script. Aurora Service has a lot to do with stepping physics and predictions. The predictions are most likely prediction where a physics object would go and would explain why you might want to dump mispredictions.
I don’t think they were. The video is of an internal build of Roblox (as indicated at the top right of the video), which us plebians do not (or at least aren’t meant to) have access to.
The aurora script (plus its associated services) have the strikethrough in their name, indicating deprecation.
