Snapshots

Types

SnapshotData<T>

Field Type Description
t number The snapshot timestamp
value T The stored value

Snapshot<T>

A snapshot buffer with indexing and interpolation.

Field / Method Type Description
cache { SnapshotData<T> } Internal buffer
lerp(a: T, b: T, alpha: number) (T, T, number) -> T Linear interpolation function for type T
Push(t, value) (self, number, T) -> () Inserts a snapshot at timestamp t
GetLatest() (self) -> SnapshotData<T>? Returns the most recent snapshot
GetAt(t) (self, number) -> T? Returns an interpolated value at time t

Methods

Push(t: number, value: T)

Inserts a snapshot into the buffer.

  • Maintains chronological order
  • Overwrites oldest entries when full

GetLatest() → SnapshotData<T>?

Returns the most recent snapshot, or nil if empty.

GetAt(t: number) → T?

Returns the interpolated value at timestamp t:

  • Interpolates linearly between before and after snapshots
  • Handles wrap-around between 0 and 255 timestamps
  • Returns the closest value if interpolation is not possible

Usage Notes

  • lerp must handle your type T (e.g., CFrame.Lerp, Vector3:Lerp)
  • Used internally by Chrono replication for smooth CFrame interpolation
  • Buffer automatically handles late or out-of-order packets without breaking motion continuity
