UBlueprintVariableNodeSpawner | Unreal Engine 5.7 Documentation

API > API/Editor > API/Editor/BlueprintGraph

Takes care of spawning variable getter/setter nodes. Serves as the "action" portion for certain FBlueprintActionMenuItems. Evolved from FEdGraphSchemaAction_K2Var, and can spawn nodes for both member-variables and local function variables.

Functions

Public

Name	Remarks	Include Path
FFieldVariant GetVarOuter()	If this is a local variable, then this will return the UEdGraph that it belongs to, otherwise it pulls the outer from the wrapped member-variable property.	BlueprintVariableNodeSpawner.h
FProperty const * GetVarProperty ()	Accessor to the variable's property.	BlueprintVariableNodeSpawner.h
FEdGraphPinType GetVarType()	Utility function for easily accessing the variable's type (needs to pull the information differently if it is a local variable as opposed to a member variable with a FProperty).	BlueprintVariableNodeSpawner.h
bool IsLocalVariable()	Since this spawner can wrap both local and member variables, we use this method to discern between the two.	BlueprintVariableNodeSpawner.h
bool IsUserLocalVariable()		BlueprintVariableNodeSpawner.h

Overridden from UBlueprintNodeSpawner

Name	Remarks	Include Path
virtual FBlueprintNodeSignature GetSpawnerSignature ()	We want to be able to compare spawners, and have a signature that is rebuildable on subsequent runs.	BlueprintVariableNodeSpawner.h
virtual FBlueprintActionUiSpec GetUiSpec ( FBlueprintActionContext const& Context, FBindingSet const& Bindings ) const	Takes the default FBlueprintActionUiSpec and modifies it dynamically to accommodate the current context.	BlueprintVariableNodeSpawner.h
virtual UEdGraphNode * Invoke ( UEdGraph* ParentGraph, FBindingSet const& Bindings, FVector2D const Location ) const	Takes care of spawning a node for the specified graph.	BlueprintVariableNodeSpawner.h
virtual void Prime ()	Not required, but intended to passively help speed up menu building operations.	BlueprintVariableNodeSpawner.h

Static

Name	Remarks	Include Path	Unreal Specifiers
static UBlueprintVariableNodeSpawner * CreateFromLocal ( TSubclassOf< UK2Node_Variable > NodeClass, UEdGraph* VarContext, FBPVariableDescription const& VarDesc, FProperty* VarProperty, UObject* Outer )	Creates a new UBlueprintVariableNodeSpawner, charged with spawning a local-variable node (for a variable that belongs to a specific graph).	BlueprintVariableNodeSpawner.h
static UBlueprintVariableNodeSpawner * CreateFromMemberOrParam ( TSubclassOf< UK2Node_Variable > NodeClass, FProperty const* VarProperty, UEdGraph* VarContext, UClass* OwnerClass )	Creates a new UBlueprintVariableNodeSpawner, charged with spawning a member-variable node (for a variable that has an associated FProperty)	BlueprintVariableNodeSpawner.h
