Constructors

  Type Name Description
Public function  

UK2Node_PromotableOperator ( const FObjectInitializer& ObjectInitializer
)

  

Functions

  Type Name Description
Public function Static bool

CanConvertComparisonOperatorNodeType ( const UEdGraphNode* Node
)

 Returns true if we can convert this node to another comparison operator type.
Public function Const bool

CanConvertPinType ( const UEdGraphPin* Pin
)

 Returns true if the given pin can be converted via the context menu to another type
Public function Static void

ConvertComparisonOperatorNode ( UEdGraphNode* Node,
const FName NewOpName
)

 Converts the given node to use the new operator name
Public function void

ConvertPinType ( UEdGraphPin* PinToChange,
const FEdGraphPinType NewPinType
)

 Convert the given pin to the new pin type.
Public function Const UEdGraphPin * Attempts to find the error tolerance pin on this node. Can return nullptr.
Public function Const UEdGraphPin *

GetAdditionalPin ( int32 PinIndex
)

 Gets the additional pin that was created at this index
Public function Const const FName  
Public function Const UEdGraphPin * Returns the first pin with the EGPD_Output direction
Public function Virtual void  
Public function void Recombines all split pins and sets the node to have default values (all wildcard pins)

Overridden from UK2Node_CallFunction

  Type Name Description
Public function Virtual void  
Protected function Virtual Const bool By default, pure nodes can be toggled.
Public function Virtual Const void

GetNodeContextMenuActions ( UToolMenu* Menu,
UGraphNodeContextMenuContext* Context
)

  
Public function Virtual Const FText  
Public function Virtual void

PinDefaultValueChanged ( UEdGraphPin* Pin
)

  
Public function Virtual void  
Public function Virtual void

SetFromFunction ( const UFunction* Function
)

 Set properties of this node from a supplied function (does not save ref to function)

Overridden from UK2Node

  Type Name Description
Public function Virtual void

AutowireNewNode ( UEdGraphPin* FromPin
)

  
Public function Virtual void

ExpandNode ( FKismetCompilerContext& CompilerContext,
UEdGraph* SourceGraph
)

 Expands a node while compiling, which may add additional nodes or delete this node
Public function Virtual Const void

GetPinHoverText ( const UEdGraphPin& Pin,
FString& HoverTextOut
)

  
Public function Virtual Const bool

IsConnectionDisallowed ( const UEdGraphPin* MyPin,
const UEdGraphPin* OtherPin,
FString& OutReason
)

  
Public function Virtual void

NotifyPinConnectionListChanged ( UEdGraphPin* Pin
)

 Called when the connection list of one of the pins of this node is changed in the editor, after the pin has had it's literal cleared
Public function Virtual void Called at the end of ReconstructNode, allows node specific work to be performed
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)

Overridden from IK2Node_AddPinInterface

  Type Name Description
Public function Virtual void Add an additional input pin to this node
Public function Virtual Const bool Determines if a pin can be added to this node.
Public function Virtual Const bool

CanRemovePin ( const UEdGraphPin* Pin
)

 Returns true if the given pin can be removed from this node.
Public function Virtual void

RemoveInputPin ( UEdGraphPin* Pin
)

 Attempt to remove the given pin from this node.
