Tips & Tricks#

Useful examples https://www.ue4community.wiki/logging-lgpidy6i

  • Prefer Implementable Event of Delegate Assignment Users can receive the event right away in the case of implementable event Blueprint Assignable have to be assigned first during begin play which might happen after the event is fired!

UFUNCTION(BlueprintImplementableEvent, Category = "Team", meta = (DisplayName = "OnTeamAssigned"))
void ReceiveTeamAssigned(FGenericTeamId NewTeam);

static FName NAME_AGKCharacterBase_ReceiveTeamAssigned = FName(TEXT("ReceiveTeamAssigned"));
void AGKCharacterBase::ReceiveTeamAssigned(FGenericTeamId NewTeam)
{
    GKCharacterBase_eventReceiveTeamAssigned_Parms Parms;
    Parms.NewTeam=NewTeam;
    ProcessEvent(FindFunctionChecked(NAME_AGKCharacterBase_ReceiveTeamAssigned),&Parms);
}

Logging values#

FName name;
UE_LOG(LogChessy, Verbose, TEXT("Creating a new render target for %s"), *name.ToString());

Finding an instance by type/class

TSubclassOf<AFogOfWarVolume> classToFind = AFogOfWarVolume::StaticClass();
UGameplayStatics::GetAllActorsOfClass(GetWorld(), classToFind, OutActors);

Doxygen Friendly#

// Do not put arguments to UCLASS, doxygen does not like it, the whole header file will get ignored
UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
class GAMEKIT_API UFogOfWarComponent : public UActorComponent
{
    //
};

    // UE_LOG(LogTemp, Warning, TEXT("%fx%f"), CamDir.X, CamDir.Y);


    InputComponent->BindAction("SetDestination", IE_Pressed, this, &AChessyPlayerController::OnSetDestinationPressed);
    InputComponent->BindAction("SetDestination", IE_Released, this, &AChessyPlayerController::OnSetDestinationReleased);

    // support touch devices
    InputComponent->BindTouch(EInputEvent::IE_Pressed, this, &AChessyPlayerController::MoveToTouchLocation);
    InputComponent->BindTouch(EInputEvent::IE_Repeat, this, &AChessyPlayerController::MoveToTouchLocation);

    InputComponent->BindAction("ResetVR", IE_Pressed, this, &AChessyPlayerController::OnResetVR);

UFUNCTION(BlueprintCallable)

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameSpeed)

CameraBoom->SetupAttachment(RootScene);

Generating Textures#

You can use blender to generate texture and use an orthographic camera to export the render as texture.

  • Create square plan with the material we want to export

  • Set Output Resolution to 1024x1024

  • Set Camera Type to Orthographic

  • Set Camera Orthographic scale to match the plan

  • Render (F12), save render to file
