Question 1:

  1. Create some actor or pawn or character with bReplicate = true
  2. Add function like “SetCameraRotation” to that actor with “Server” option
  3. Add function body “SetCameraRotation_Implementation” with code

When client call “SetCameraRotation” with FVector param - UE call “SetCameraRotation_Implementation” on server with same param inside server version of actor.

Example:
Header:

UFUNCTION(Server, Reliable, WithValidation)
	void SERVER_Fire();
	bool SERVER_Fire_Validate();
	void SERVER_Fire_Implementation();

UFUNCTION(NetMulticast, Reliable)
	void MULTICAST_Fire();
	void MULTICAST_Fire_Implementation();

CPP:

bool ASomePawn::SERVER_Fire_Validate(){ return true; }
void ASomePawn::SERVER_Fire_Implementation()
{
	MULTICAST_Fire();
}

void ASomePawn::MULTICAST_Fire_Implementation()
{
	..Some code..
}

Client1 call SERVER_Fire → SERVER_Fire_Implementation called on server and it call MULTICAST_Fire → all client call MULTICAST_Fire_Implementation.

So that way client can call function on all client and server with any param you want.
