Struct GhostPredictionHistorySystem

A system used to make a backup of the current predicted state, right after the last full (not fractional) tick in a prediction loop for a frame has been completed. The backup does a memcopy of all ghost components (into a separate memory area connected to the chunk). The backup is used to restore the last full tick, to continue prediction when no new data has arrived. Note: When this happens, only the fields which are actually serialized as part of the snapshot are copied back, not the full component. Thus, preserving any non-GhostField state. The backup data is also used to:

  • Detect errors in the prediction.
  • To add smoothing of predicted values.
