UE4 RPC函数_Implementation未调用

Question

很抱歉，但是我的英语说得不好。

我的.h：

UFUNCTION()
void AttachToPlayer(USkeletalMeshComponent* Mesh, const FName &SocketName);

UFUNCTION(Server, Reliable, WithValidation)
void ServerAttachToPlayer(USkeletalMeshComponent* Mesh, const FName &SocketName);

virtual void ServerAttachToPlayer_Implementation(USkeletalMeshComponent* Mesh, const FName &SocketName);

virtual bool ServerAttachToPlayer_Validate(USkeletalMeshComponent* Mesh, const FName &SocketName);

我的cpp：

void ABagPlayer::AttachToPlayer(USkeletalMeshComponent* Mesh, const FName &SocketName)
{
    if (Role == ROLE_Authority)
    {
         GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Red, TEXT("TEST"));
    }
    else
    {
        ServerAttachToPlayer(Mesh, SocketName);
    }
}


bool ABagPlayer::ServerAttachToPlayer_Validate(USkeletalMeshComponent* Mesh, const FName &SocketName)
{
    return true;
}


void ABagPlayer::ServerAttachToPlayer_Implementation(USkeletalMeshComponent* Mesh, const FName &SocketName)
{
    AttachToPlayer(Mesh, SocketName);
}

我不明白为什么，当我的客户端启动功能“ AttachToPlayer”时，未调用功能“ ServerAttachToPlayer_Implementaion”。 但是，如果是服务器调用“ AttachToPlayer”，则会调用函数“ ServerAttachToPlayer_Implementaion”。

我尝试了很多事情，我正在拔头发！
