C++ Replicating Animations

What’s wrong:

  • HOST can see the CLIENTS FireAnimation.

  • CLIENTS can’t see the HOST’s FireAnimation.

  • CLIENTS can’t see other CLIENTS FireAnimation.

What is needed:

What would need to be changed with the following code so that all CLIENTS and HOST can see any connected player’s FireAnimation? Is only a Replicated Multicast Function needed for the solution? What about only using a Replicated Server Function?

PLEASE NOTE:

bReplicates = true; // In player’s the constructor

I’ve already read this:

// ACharacter.h

public:
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Gameplay, Replicated)
  class UAnimMontage* FireAnimation;

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = WeaponUsage, Replicated)
  class USoundBase* FireSound;

UFUNCTION(NetMulticast, Unreliable)
    void MulticastSetFiring();

UFUNCTION(Server, Reliable, WithValidation)
    void ServerSetFiring();

protected:
void OnFire();

// ACharacter.cpp

void ACharacter::GetLifetimeReplicatedProps(TArray< FLifetimeProperty > & OutLifetimeProps) const
{
  Super::GetLifetimeReplicatedProps(OutLifetimeProps);

  DOREPLIFETIME(ACharacter, FireAnimation);
  DOREPLIFETIME(ACharacter, FireSound);
}

void ACharacter::SetupPlayerInputComponent(class UInputComponent* InputComponent)
{
  // set up gameplay key bindings
  check(InputComponent);

  InputComponent->BindAction("Fire", IE_Pressed, this, &ACharacter::OnFire);
}

// WIP - Only Server can see animations of clients.
void ACharacter::MulticastSetFiring_Implementation()
{
  // try and play the sound if specified
  if (FireSound != NULL)
  {
    UGameplayStatics::PlaySoundAtLocation(this, FireSound, GetActorLocation());
  }

  // try and play a firing animation if specified
  if (FireAnimation != NULL)
  {
    // Get the animation object for the arms mesh
    UAnimInstance* AnimInstance = Mesh1P->GetAnimInstance();
    if (AnimInstance != NULL)
    {
      AnimInstance->Montage_Play(FireAnimation, 1.f);
    }
  }
}

void ACharacter::ServerSetFiring_Implementation()
{
  // try and play the sound if specified
  if (FireSound != NULL)
  {
    UGameplayStatics::PlaySoundAtLocation(this, FireSound, GetActorLocation());
  }

  // try and play a firing animation if specified
  if (FireAnimation != NULL)
  {
    // Get the animation object for the arms mesh
    UAnimInstance* AnimInstance = Mesh1P->GetAnimInstance();
    if (AnimInstance != NULL)
    {
      AnimInstance->Montage_Play(FireAnimation, 1.f);
    }
  }
}

bool ACharacter::ServerSetFiring_Validate()
{
  return true;
}

void ACharacter::OnFire()
{
  if (Role < ROLE_Authority)
  {
    ServerSetFiring();
  }
  else
  {
    MulticastSetFiring();
  }
}
