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"

Strange client replication jitter.

Hello everybody,

I'm running into an incredibly annoying issue that has me perplexed. The aim is to have my character follow the cursor and rotate around it and have this replicate for every player. It does this, however there seems to be a very strange location jitter on the client's perspective. The rotation replicates just fine, however the location is what seems to jitter whilst it is moving. Here is my code, if anybody can point me in the direction of where/how to fix this it would be greatly appreciated!

 void ASkyDiveCharacter::OnRep_PosChange()
 void ASkyDiveCharacter::OnRep_RotChange()
 void ASkyDiveCharacter::MoveForward(float Value)
     if (!Controller || Value == 0.0f) return;
     ASkyDivePlayerController* PlayerController = Cast<ASkyDivePlayerController>(GetController());
     if (PlayerController)
         FVector mouseLocation, mouseDirection;
         PlayerController->DeprojectMousePositionToWorld(mouseLocation, mouseDirection);
         FVector EndLoc = mouseLocation + mouseDirection * 10000;
         FCollisionQueryParams Sky_TraceParams = FCollisionQueryParams(FName(TEXT("Sky_Trace")), true, this);
         Sky_TraceParams.bTraceComplex = true;
         Sky_TraceParams.bTraceAsyncScene = true;
         Sky_TraceParams.bReturnPhysicalMaterial = false;
         FHitResult RV_Hit(ForceInit);
         if (Role != ROLE_Authority && IsLocallyControlled())
                 FVector RotVec(GetActorLocation() - RV_Hit.Location);
                 float    BreakVecRot(FMath::RadiansToDegrees(FMath::Atan2(RotVec.Y, RotVec.Z)) * 1 - 90);
                 FVector BreakVec(0, RV_Hit.Location.Y, RV_Hit.Location.Z);
                 SetActorLocation(FMath::VInterpConstantTo(GetActorLocation(), BreakVec, Value * 260, 5));
                 //SetActorRotation(FRotator(0, 0, BreakVecRot));
                 SetActorRotation(FMath::RInterpTo(GetActorRotation(), FRotator(0, 0, BreakVecRot), Value * 3, 5));
         if (Role < ROLE_Authority)
                 FVector RotVec(CurrentPosition - RV_Hit.Location);
                 float    BreakVecRot(FMath::RadiansToDegrees(FMath::Atan2(RotVec.Y, RotVec.Z)) * 1 - 90);
                 FVector BreakVec(0, RV_Hit.Location.Y, RV_Hit.Location.Z);
                 ServerMoveForward(FMath::VInterpConstantTo(CurrentPosition, BreakVec, Value * 260, 5), FMath::RInterpTo(CurrentRotation, FRotator(0, 0, BreakVecRot), Value * 3, 5));
 bool ASkyDiveCharacter::ServerMoveForward_Validate(FVector Location, FRotator Rotation)
     return true;
 void ASkyDiveCharacter::ServerMoveForward_Implementation(FVector Location, FRotator Rotation)
     CurrentPosition = GetActorLocation();
     CurrentRotation = GetActorRotation();

 void ASkyDiveCharacter::GetLifetimeReplicatedProps(TArray< FLifetimeProperty > & OutLifetimeProps) const
     DOREPLIFETIME(ASkyDiveCharacter, CurrentPosition);
     DOREPLIFETIME(ASkyDiveCharacter, CurrentRotation);
