Client Prediction and Server Reconciliation for Pawn

Here’s how player movement prediction, replication and correction works in network games:

Every tick, the TickComponent() function is called. It figures out the acceleration and rotation change for the frame,
and then calls PerformMovement() (for locally controlled Characters), or ReplicateMoveToServer() (if it’s a network client).

ReplicateMoveToServer() saves the move (in the PendingMove list), calls PerformMovement(), and then replicates the move
to the server by calling the replicated function ServerMove() - passing the movement parameters, the client’s
resultant position, and a timestamp.

ServerMove() is executed on the server. It decodes the movement parameters and causes the appropriate movement
to occur. It then looks at the resulting position and if enough time has passed since the last response, or the
position error is significant enough, the server calls ClientAdjustPosition(), a replicated function.

ClientAdjustPosition() is executed on the client. The client sets its position to the servers version of position,
and sets the bUpdatePosition flag to true.

When TickComponent() is called on the client again, if bUpdatePosition is true, the client will call
ClientUpdatePosition() before calling PerformMovement(). ClientUpdatePosition() replays all the moves in the pending
move list which occurred after the timestamp of the move the server was adjusting.

You are a lifesaver!! Thank you!
