FKismetConnectionDrawingPolicy ( int32 InBackLayerID,

Functions

  Type Name Description
Protected function Const bool Checks that the specified nodes are connected in the graph directly by an exec pin.
Protected function FTimePair const *

BackTraceExecPath ( UEdGraphPin const*const OutputPin,
FExecPairingMap const*const NodeExecutionList
)

 With the introduction of "reroute" (UK2Node_Knot) nodes, we have to backtrace to find a node that was actually executed before the one in question (knot nodes are removed at compile time, and therefore never executed).
Public function Virtual void  
Public function Const void

CalculateEnvelopeAlphas ( double ExecutionTime,
float& AttackAlpha,
float& SustainAlpha
)

  
Public function Virtual Const bool  
Protected function Const bool

CanBuildRoadmap ( UBlueprint* TargetBP
)

 Determines if the given Blueprint context has a valid object for debugging.
Public function Virtual void

DetermineStyleOfExecWire ( float& Thickness,
FLinearColor& WireColor,
bool& bDrawBubbles,
const FTimePair& Times
)

  
Protected function Const bool

FindPinCenter ( UEdGraphPin* Pin,
FVector2D& OutCenter
)

  
Protected function Const bool

GetAverageConnectedPosition ( UK2Node_Knot* Knot,
EEdGraphPinDirection Direction,
FVector2D& OutPos
)

  
Protected function Const UBlueprint * Determines the target Blueprint for querying the active debugging context.
Protected function bool  
Protected function Virtual Const bool

TreatWireAsExecutionPin ( UEdGraphPin* InputPin,
UEdGraphPin* OutputPin
)

 Should this wire be treated as an execution pin, querying the execution trace for connected nodes to draw it differently?

Overridden from FConnectionDrawingPolicy

  Type Name Description
Public function Virtual void

DetermineWiringStyle ( UEdGraphPin* OutputPin,
UEdGraphPin* InputPin,
FConnectionParams& Params
)

 Give specific editor modes a chance to highlight this connection or darken non-interesting connections.
Public function Virtual void

Draw ( TMap< TSharedRef< SWidget >, FArrangedWidget >& PinGeometries,
FArrangedChildren& ArrangedNodes
)

  
Public function Virtual void

)

  
Public function Virtual void

SetIncompatiblePinDrawState ( const TSharedPtr< SGraphPin >& StartPin,

Classes

  Type Name Description
Protected struct FTimePair Times for one execution pair within the current graph.  

Typedefs

Name Description
FExecPairingMap Map of exec-pins to a pair of execution times (holds timing info for the owning-node, paired with a time of execution for the linked node)...
