Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Call Server function from Client on attached Actor

Hello and Thank You.

I have an class Backpack.h

     UFUNCTION(Reliable, Server, WithValidation)
     void AddItem(AItem* item);
     virtual void AddItem_Implementation(AItem* item);
     virtual bool AddItem_Validate(AItem* item);


 void ABackpack::AddItem_Implementation(AItem *item)
     UE_LOG(YourLog, Warning, TEXT("[AddItem]server item %s"), *item->Name);

Attach Backpack to Character

 void ANetworkTestCharacter::EquipOnSlot_Implementation(AItem* bp, FName slot)
     LocalEquipOnSlot(bp, slot);
     if(Role == ROLE_Authority) {
         UE_LOG(YourLog, Warning, TEXT("[EquipOnSlot]Slot is %s"), *slot.ToString());
         EquipOnSlot_RPC(bp, slot);
 void ANetworkTestCharacter::LocalEquipOnSlot(AItem* item, FName slot) {
     UE_LOG(YourLog, Warning, TEXT("[LocalEquipOnSlot]Slot is %s"), *slot.ToString());
     ABackpack* bp = Cast<ABackpack>(item);
     if (bp != NULL) {
         USkeletalMeshComponent* sm = bp->FindComponentByClass<USkeletalMeshComponent>();
         if(sm != NULL) {
         bp->AttachRootComponentTo(GetMesh(), slot, EAttachLocation::SnapToTarget);

Problem part:

 ABackpack* backpack = Cast<ABackpack>(*Itr);
  if(backpack != NULL) {
      backpack->AddItem(item); // Doesn't call on Server
