Unreal Dump

  • TEnumRange

    • see \Runtime\Core\Public\Misc\EnumRange.h.
    • for (const EMyEnum Val : TEnumRange<EMyEnum>())
    • Required to use ENUM_RANGE_BY_COUNT, ENUM_RANGE_BY_FIRST_AND_LAST, or ENUM_RANGE_BY_VALUES

  • BlueprintAuthorityOnly, tbh some of these TIL.

    • UFUNCTION(BlueprintCallable, BlueprintAuthorityOnly, Category = "MyCategory")

  • EditCondition, VisibleCondition, and EditConditionHides

    • UPROPERTY(..., meta = (EditCondition="bToggled")) or UPROPERTY(..., meta = (EditCondition="MyEnum == MyEnum::None")) etc

  • FSimpleMulticastDelegate and FSimpleDelegate

    • These are delegates that you can bind only in C++ and don’t support any args. If using these you don’t have to do the macro to define them as they’re already defined so it helps clean up your classes.

  • TArrayView

    • You can do some cool stuff with this class, such as splitting an array.

  • FDateRange, FDoubleRange, FFloatRange, FInt8Range, FInt16Range, FInt32Range, FInt64Range -

    • see \Runtime\Core\Public\Math\Range.h

  • APlayerState::CopyProperties and APlayerState::OverrideWith

  • FWorldDelegates 

  • UE_NONCOPYABLE macro

  • FFormatNamedArguments

  • UE_ARRAY_COUNT

  • ThisClass - used when well… using delegates etc &ThisClass::MethodName

  • UEnum class - has some really useful methods

  • PawnLeavingGame - override this in your PlayerController class and it will prevent your pawn from being destroyed on disconnect

  • FDebug::DumpStackTraceToLog to dump the callstack to the log

  • ObjectInitializer.DoNotCreateDefaultSubobject

  • NotifyControllerChanged on the Pawn

  • #include UE_INLINE_GENERATED_CPP_BY_NAME(ClassFileName) in cpp files

  • ULineBatchComponent - useful for drawing debug (DrawDebug*)

  • UE_DISABLE_OPTIMIZATION & UE_ENABLE_OPTIMIZATION

  • FMessageLog(“MapCheck”).*

  • [/Script/EngineSettings.GameMapsSettings] - EditorTemplateMapOverrides

until next time
