Variables

  Type Name Description
Public variable UProperty uint32: 1 bCanHaveInputs Whether this node is allowed to have inputs.
Public variable UProperty uint32: 1 bCanHaveOutputs Whether this node is allowed to have outputs.
Public variable UProperty TObjectPtr< UK2Node_Tunnel > InputSinkNode The input pins of this tunnel go to the output pins of InputSinkNode.
Public variable UProperty FKismetUserDeclaredFunctionMetadata MetaData The metadata for the function/subgraph associated with this tunnel node; it's only editable and used on the tunnel entry node inside the subgraph or macro.
Public variable UProperty TObjectPtr< UK2Node_Tunnel > OutputSourceNode The output pins of this tunnel node came from the input pins of OutputSourceNode.
Protected variable TArray< UEdGraphPin * > WildcardPins Cache of the pins that were created as wildcards.

Constructors

Functions

  Type Name Description
Protected function void Utility function that subclasses must call after allocating their default pins.
Public function Virtual Const bool  
Public function Virtual Const bool  
Public function Virtual Const FName

CreateUniquePinName ( FName SourcePinName
)

  
Public function Virtual void  
Public function Virtual Const UK2Node_Tunnel * The input pins of this tunnel go to the output pins of InputSinkNode (can be NULL).
Public function Virtual Const FText

GetNodeTitle ( ENodeTitleType::Type TitleType
)

  
Public function Virtual Const UK2Node_Tunnel * The output pins of this tunnel node came from the input pins of OutputSourceNode (can be NULL).
Public function Virtual Const FText  
Public function Virtual Const bool

IsCompatibleWithGraph ( const UEdGraph* InGraph
)

  
Protected function Virtual void

PostFixupAllWildcardPins ( bool bInAllWildcardPinsUnlinked
)

 Handles any work needed to be done after fixing up all wildcard pins during reconstruction
Public function Virtual void  
Protected function Static bool Feature flag for 'smart' wildcard inference which allows for multiple types to be inferred.

Overridden from UK2Node_EditablePinBase

  Type Name Description
Public function Virtual bool

CanCreateUserDefinedPin ( const FEdGraphPinType& InPinType,
EEdGraphPinDirection InDesiredDirection,
FText& OutErrorMessage
)

 Queries if a user defined pin of the passed type can be constructed on this node.
Public function Virtual bool Can this node have execution wires added or removed?
Public function Virtual Const bool Can this node have pass-by-reference parameters?
Public function Virtual UEdGraphPin *

CreatePinFromUserDefinition ( const TSharedPtr< FUserPinInfo > NewPinInfo
)

 Creates a new pin on the node from the specified user pin info.
Public function Virtual bool

ModifyUserDefinedPinDefaultValue ( TSharedPtr< FUserPinInfo > PinInfo,
const FString& NewDefaultValue
)

 Modifies the default value of an existing pin on the node, this will update both the UserPinInfo and the linked editor pin

Overridden from UK2Node

  Type Name Description
Public function Virtual void

ClearCachedBlueprintData ( UBlueprint* Blueprint
)

 Clears out any cached data that needs to be regenerated after a structural blueprint change
Public function Virtual Const bool Return whether to draw this node as an entry
Public function Virtual Const bool Return whether to draw this node as an entry
Public function Virtual void

FixupPinStringDataReferences ( FArchive* SavingArchive
)

 Fixes up structure/soft object ref pins, on both save and load
Public function Virtual Const UObject *  
Public function Virtual Const bool Query if this is a node that is safe to ignore (e.g., a comment node or other non-structural annotation that can be pruned with no warnings).
Public function Virtual Const bool Return true if adding/removing this node requires calling MarkBlueprintAsStructurallyModified on the Blueprint
Public function Virtual void

ReallocatePinsDuringReconstruction ( TArray< UEdGraphPin* >& OldPins
)

 Reallocate pins during reconstruction; by default ignores the old pins and calls AllocateDefaultPins() If you override this to create additional pins you likely need to call RestoreSplitPins to restore any pins that have been split (e.g. a vector pin split into its components)
Public function Virtual ERenamePinResult

RenameUserDefinedPinImpl ( const FName OldName,
const FName NewName,
bool bTest
)

 Implementation function that renames an existing pin on the node. Does not broadcast notifications.
Public function Virtual Const void

ValidateNodeDuringCompilation ( FCompilerResultsLog& MessageLog
)
