StateInterpolationBuffer class
Interpolation buffer for actor positions received from a remote authority.
Ring buffer of timestamped positions received over the network, sampled ServerDelay milliseconds in the past so movement stays smooth between (and across late) updates. Shared by the server-side shadow of a remote player (RemotePlayerOnServer) and by client-side remote actors (RemoteActor).
Public static variables
-
static std::
int64_t ServerDelay constexpr - How far in the past the received state is displayed, in milliseconds.
Public static functions
-
static auto Now() -> std::
int64_t - Returns the current timestamp of the interpolation clock, in milliseconds.
Public functions
-
void Reset(Vector2f pos,
std::
int64_t now) - Resets the whole buffer to a single position (spawn, warp, forced resync), disabling interpolation.
- auto GetLatest() const -> Vector2f
- Returns the most recently pushed position.
-
void Push(Vector2f pos,
std::
int64_t now, bool wasVisible) - Pushes a newly received position.
-
auto Sample(std::
int64_t renderTime, Vector2f& result) const -> bool - Samples the interpolated position at the given time.
Function documentation
void Jazz2::
Pushes a newly received position.
When wasVisible is false, the actor was hidden before this update, so the previous and current frames are collapsed to the new position to disable interpolation across the gap.
bool Jazz2::
Samples the interpolated position at the given time.
| Returns | true and writes result when renderTime is covered by the buffer; false when it is ahead of the newest received state, in which case result is left untouched. |
