<h1>CorrectPlayerMovePredictionPacket (161)</h1>
|
|
<div class="description">Sent to a player when their simulation of movement mismatches enough from the server that it wants to correct the client.</div>
|
|
<div class="description">Used only in server authoritative movement mode, see ServerAuthMovementMode documentation.<br>
|
|
Since it is sent to the specified client the target player is implied to be the receiver.<br>
|
|
It is an optional part of the server authoritative protocol. A server could choose to never send this or do all corrections
|
|
through MovePlayerPacket, although doing so would likely provide less smooth results.</div>

<td>In server authoritative movement mode the client supplies this in PlayerAuthInputPacket.

For any client-bound packets containing a tick, the server should supply the tick value corresponding to the most recently processed PlayerAuthInputPacket.
|
|
This allows the client to adjust any client predictions made while the packet was in flight.
|
|
If the packet is being sent to the client but not relating to data of the player or a client-predicted vehicle, it can be zero.
|
|
It is also acceptable to specify zero for players, although this may lead to minor visual flickers and less smooth application of CorrectPlayerMovePredictionPacket.</td>
