Movement is not fluid in standalone (On the client) (stuttering)

The command “p.NetShowCorrections 1” shows two capsules (one red and one green).
And a message in the console.

[2024.12.09-04.21.55:986][417]LogNetPlayerMovement:

I can imagine there is a difference in position between the server and the client. Right?

I assumed that replicating movement would take care of this.

This is the character replication settings:

And this is my movement function:


void AMyPlayer::InputMove(const FInputActionValue &Value)
{		
	// input is a Vector2D
	const FVector2D MovementVector = Value.Get<FVector2D>();

	if (!IsValid(Controller)) return;
	
	// find out which way is forward
	const FRotator Rotation = Controller->GetControlRotation();
	const FRotator YawRotation(0, Rotation.Yaw, 0);

	// get forward vector
	const FVector ForwardDirection = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::X);

	// get right vector 
	const FVector RightDirection = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::Y);

	// add movement 
	AddMovementInput(ForwardDirection, MovementVector.Y);
	AddMovementInput(RightDirection, MovementVector.X);
}

The error occurs in this scope

AMyPlayer::InputMove => No Authority / Client / ROLE_AutonomousProxy /

I tried to run the function on the server only

	UFUNCTION(Server,Unreliable)
	void InputMove(const FInputActionValue &Value);

and also in multicast.

	UFUNCTION(NetMulticast,Unreliable)
	void InputMove(const FInputActionValue &Value);

But it didn’t fix the problem.
What is wrong? What should I do?

Thank you so much!!
