UBlueprintSetLibrary::Set_ToArray

function Engine Blueprint Since unknown

#include "Kismet/BlueprintSetLibrary.h"

Access: public Specifiers: staticBlueprintCallableCustomThunk

Description

Copies the contents of a set into an array, useful whenever you need index-based access or a fixed iteration order.

Caveats & Gotchas

• The resulting array order matches the set's internal iteration order, not insertion order, and is not guaranteed to stay stable across further mutations of the set.
• In C++, construct the array with TSet::Array() instead of routing through this wildcard node.

Signature

static void Set_ToArray(const TSet<int32>& A, TArray<int32>& Result);

Parameters

Name	Type	Description	Default
A	const TSet<int32>&	Wildcard placeholder for the source set.	—
Result	TArray<int32>&	Output array populated with a copy of every element in A.	—

Return Type

void

Example

Convert a set to an array C++

TSet<FName> UnlockedLevels = { TEXT("Level01"), TEXT("Level02") };
TArray<FName> LevelArray = UnlockedLevels.Array(); // native TSet::Array — the direct equivalent of the Set_ToArray node
