I’m finding something strange when trying to test using a NetMulticast in playercontroller. I have the following:
CPlayerController.h
UFUNCTION(Reliable, NetMulticast)
void MulticastRPCupdatePlayerState();
void MulticastRPCupdatePlayerState_Implementation();
CPlayerController.cpp
void ACPlayerController::BeginPlay() {
Super::BeginPlay();
UKismetSystemLibrary::PrintString(this, TEXT("PC begin "), true, true, FLinearColor(1.000000, 1.000000, 1.000000, 1.000000), 40.0);
}
void ACPlayerController::SetupInputComponent() {
InputComponent->BindAction("Jump", IE_Pressed, this, &ACPlayerController::MulticastRPCupdatePlayerState);
}
void ACPlayerController::MulticastRPCupdatePlayerState_Implementation() {
UKismetSystemLibrary::PrintString(this, TEXT("PC multicast "), true, true, FLinearColor(0.000000, 0.660000, 1.000000, 1.000000), 40.0);
}
When I start the game I get a messages from both server and client of “PC begin” (twice from server because client connected) which seems all fine and good. If I press “Jump” on client, client gives a message “PC multicast”, which is expected as well.
The strange part is when I press “Jump” key on the server than I get Server:“PC Multicast”; Client:“PC Multicast”; and THEN…Client:“PC begin”. The clients camera is also reset and any further controls pressed on the client do not register (including ESC to exit testing). The server camera and controls continue to work. Now why is it calling the BeginPlay on the playercontroller again on the client when calling the Multicast function? It’s like it’s resetting the playercontroller. Then keys don’t work and camera goes back to pawn (I have bAutoManageActiveCameraTarget=false in my playercontroller). So to reiterate:
“Jump” key pressed on server
Server:“PC multicast”
Client:“PC multicast”
Client:“PC begin”
All key presses stop working on client and bAutoManageActiveCameraTarget seems to go back to true.
Here is the full code (lots of junk because just been testing/learning) in case there is anything else that is causing this:
