class UNiagaraNodeFunctionCall : public UNiagaraNodeWithDynamicPins

Variables

	Name	Description
FGuid	CachedChangeId	Adjusted every time that we compile this script.
FString	FunctionDisplayName
UNiagaraScript ...	FunctionScript
FName	FunctionScriptAssetObjectPath	A path to a script asset which can be used to assign the function script the first time that default pins are generated.
TMap< FName, FN...	FunctionSpecifiers
FOnInputsChange...	OnInputsChangedDelegate
TArray< FNiagar...	PropagatedStaticSwitchParameters	All the input values the function propagates to the next higher caller instead of forcing the user to set them directly.
FNiagaraFunctio...	Signature	Some functions can be provided a signature directly rather than a script.

ENiagaraNume...	GetNumericOutputTypeSelectionMode()	Gets which mode to use when deducing the type of numeric output pins from the types of the input pins.
UObject *...	GetReferencedAsset()	Gets the asset referenced by this node, or nullptr if there isn't one.
bool	RefreshFromExternalChanges()	Refreshes the node due to external changes, e.g. the underlying function changed for a function call node.
void	SubsumeExternalDependencies ( TMap< const UObject*, UObject ... )	Determine if there are any external dependencies wrt to scripts and ensure that those dependencies are sucked into the existing package.
void	UpdateCompileHashForNode ( FSHA1& HashState )	Old style compile hash code. To be removed in the future.
